Leading by examples – retrofitting all types of social housing – part two

Posted on by

By Ian Babelon

In the first part of two blog posts, published on 22 May, Ian Babelon provided examples of good practice in retrofitting social housing. The second part of this blog post looks at estate-wide and area-wide social housing retrofits.

Introduction

Upscaling social housing retrofits requires learning from individual property retrofits and wider retrofitting programmes. With numbers comes greater complexity. As capacity grows, opportunities for partnerships provide new opportunities to embed retrofit programmes in wider sectoral and place-based strategies. This post considers the role of estate-wide and area-wide social housing retrofits, including how these can benefit from tenant engagement for healthy, inclusive placemaking.

Estate-wide retrofits

Low-carbon retrofitting measures on Lancaster West Estate at the Royal Borough of Kensington and Chelsea have included Energiesprong whole house retrofits at 38 homes, energy-efficiency measures at 367 homes across seven blocks, and testing mechanical ventilation heat recovery systems. The latest measure is the fully carbon-neutral retrofit at Treadgold House. Other measures have included public realm and safety improvements. Along with the extensive resident engagement, the estate has witnessed a deep one-of-a-kind transformation.

However, estate-wide retrofits can be difficult to plan and deliver to a high energy-efficiency standard due to the large up-front costs involved. A mix of whole-house retrofits, fabric-first approaches, redevelopment of poorly designed buildings, and essential scheduled upgrades might be preferable, depending on the context and the heavy cost of building safety compliance.

The acclaimed Passivhaus redevelopment of Agar Grove in Camden, based on the masterplan by Hawkins\Brown, features a mix of solutions that make the estate-wide regeneration more affordable for both the council and residents. These include new council homes, refurbished flats, affordable rental housing, and homes for sale, enabling a tall order of 496 new homes to be delivered in six phases. Besides providing much-needed quality homes to many, the project also acts an exemplar for social and affordable housing in the UK and beyond.

Area-wide programmes

From being an early adopter of the Energiesprong approach to the Deep Retrofit Energy Model (DREeM), enabling  energy-efficient retrofits to dozens of social homes, Nottingham City Homes have been among the first in the UK to develop neighbourhood-wide retrofits. Nottingham City Council even tested the innovative use of Low Temperature District Heating along with whole house retrofits for 94 homes in Sneinton, which proved more complex than initially expected.

In Scotland, the Renfrewshire retrofit programme aims for EnerPHit or AECB Retrofit Standard for up to 3,500 homes across eight neighbourhoods. The initiative is part of a £100m housing-led regeneration programme across the local authority. Renfrewshire Council was selected as Social Landlord of the Year 2022 by the Retrofit Academy for its clear strategy to deliver large-scale housing decarbonisation, adopt the PAS2035 framework wherever possible, and for its proactive engagement of residents throughout the programme.

Other noteworthy programmes include whole house retrofits for 150 council-owned flats on the Holt Dale Estate in Leeds, reaching EPC rating A, benefitting residents who were living in fuel poverty. The 3 Cities Retrofit programme is worth following up as it has the potential to retrofit up to 165,000 social homes across the Birmingham, Coventry and Wolverhampton City Councils.

In France, 14 housing associations in Brittany have partnered to leverage the Energiesprong approach for an initial stock of 2,000 social homes, with a potential to extend the experience to 16,000 social homes. In the north of France, the housing association Maison et Cités selected hemp concrete as the most effective material for a progressive roll-out of fabric-first retrofits to 20,000 homes in the former mining region. Both area-wide retrofit approaches were part-funded by the French public investment agency Banque des Territoires.

Upscaling tenant engagement

Residents should be onboard from day one of their property’s retrofit, but they can also actively contribute to wider retrofit programmes. Insight from the Social Housing Tenants’ Climate Jury report (2021) and the Resident Voices in the Net Zero Carbon Journey report both point to the need to educate and actively involve residents from the planning phase to supporting sustainable lifestyles.

One year on, these needs were felt even more acutely in the build-up to COP26. Critically, residents have expressed that perceived contradictions in council-led environmental strategies such as recycling can have knock-on effects on how they perceive the value and effectiveness of retrofits. This implies that efforts toward improving energy-efficiency and reducing waste should be consistent.

Resident-led and national initiatives have included community gardening and the Incredible Edible network. These can provide additional involvement opportunities as well as quality food and care for the neighbourhood. The demand for greener urban spaces, biodiversity and access to wildlife also came strongly in a related report by Orbit and the Chartered Institute of Housing. Initiatives that upscale tenant engagement include recruiting tenants as board members (at Connect Housing) or embedding tenant involvement in the housing provider’s sustainability strategy (at Notting Hill Genesis).

Providers can also encourage residents to contribute to the Together with Tenants Charter led by the National Housing Federation. The organisation Tpas and partners have shared tenant engagement guidance for ALMOs and housing associations that will be useful in seeking to upscale social housing retrofits. In addition, there has been a recent ministerial push encouraging tenants to voice their concerns more readily, and therefore to exercise scrutiny over what may be dismal housing conditions.

Final thoughts

Collaboration and cross-sectoral partnerships underpinned by active tenant engagement seem essential to deliver large retrofit programmes while hedging against otherwise deterring risks. Exemplars, in turn, help build a greater ‘can do’ attitude and know-how for the wider housing and property sectors on the road to net zero, including area-wide retrofits.

Leading by examples – retrofitting all types of social housing – part one

Posted on by

By Ian Babelon

In the first of two blog posts, Idox’s Ian Babelon takes us on a tour of some of the best social housing retrofits in Britain, and beyond.

Blog posts on the Knowledge Exchange blog have repeatedly shown the need to retrofit social homes at scale to provide decent, comfortable homes while building capacity for low-carbon homes. The recent Powering Up Britain agenda highlights the long-term economic, environmental and social benefits of retrofitting homes, with the latest government funding opportunities including the second round of the Social Housing Decarbonisation Fund (SHDF2) and ECO+. Thankfully, decades of learning in the UK and internationally have led to exemplar retrofits for all types of homes. After considering best practice guidance, this post provides a selection of examples across the UK and beyond.

Designing it right

The National Housing Federation has gathered excellent industry guidance about decarbonising social homes, and how to retrofit traditional and historic homes.

For example, the Sustainable Traditional Buildings Alliance’s Guidance Wheel helps to visualise and manage the interactions between the different dimensions of retrofits required to implement the landmark PAS2035 retrofit framework.

The Sustainable Renovation Guide by the Scottish Ecological Design Guide (SEDA) also provides excellent technical guidance for retrofitting various types of homes. Airtightness is often essential to achieving good energy performance as it prevents thermal gaps, as detailed in this technical guide.

Industry-leading, on-demand webinars hosted by the Northern Housing Consortium also provide guidance and inspiration for all aspects of low-carbon social housing retrofits, from financing to neighbourhood-wide retrofits. Experience shows that having an airtightness champion in the construction team is also key to successful retrofits.

To make best use of technical and design guidance, having Unique Property Reference Numbers (UPRNs) provide a ‘golden thread’ for housing associations. Being able to accurately identify and differentiate between all properties enables compilation of complete datasets about housing stocks.

The Better Social Housing Review (2022) encourages housing associations to work together to conduct and publish an audit of the UK social housing stock. A clearer picture of all social housing can benefit both individual organisations and the wider industry in tracking progress toward decarbonisation and healthy, affordable homes for all. Recent assessments by the Regulator of Social Housing for council homes in London have further revealed the importance of up-to-date, complete datasets to monitor and guarantee building safety measures. Related benefits can include consistent monitoring of energy performance, environmental health, carbon emissions, and customer experience.

Historic and older homes

Social housing in the UK is often associated with housing construction in the period between 1947 and the 1980s. However, according to existing housing unit statistics in England for 2021, there is a total of 400,000 social homes built in the interwar period, and 273,000 social homes built before 1919. Older homes can be located in conservation areas, which limits options for retrofitting.

In 2019, Southside Housing Association used the EnerPHit retrofitting approach (involving the highest levels of energy efficiency) to pre-1919 tenements on Niddrie Road in Glasgow, with a design by John Gilbert Architects, in collaboration with Strathclyde University. As is often required for older housing, the eight one-bed flats benefitted from internal wall insulation to preserve the sandstone street façades. Natural building products were favoured as much as possible to guarantee indoor air quality and permeability while reducing embodied carbon and energy. Heating was supplied with new Air Source Heat Pumps or energy efficient combi gas boilers, along with mechanical ventilation heat recovery units (MVHRs). The project serves as a demonstration exemplar for “deep” tenement retrofits, and received funding from Glasgow City Council, the commissioning housing association, the Scottish Government and the Scottish Funding Council.

High rises

In Hamilton, Ontario, the Ken Soble Tower owned by CityHousing Hamilton was nearing the end of its life, having been built in 1967. The 2021 EnerPHit refurbishment featured external-wall and roof insulation, along with Air Source Heat Pumps. Completed in 2021, it is the first EnerPHit retrofit of an apartment tower in North America, providing 146 affordable housing units to older residents.

Back in Glasgow, the Cedars Court high-rise, comprising 314 flats, owned by Queens Cross Housing Association, benefitted from the first of its kind fabric-first EnerPHit refurbishment in Scotland between 2016 and 2019.

Further examples of high-rise retrofits include 528 flats across three tower blocks at Edward Woods Estate (2011-2014) in Shepherds Bush, Hammersmith and Fulham, and retrofits of 291 flats across two tower blocks at Ethelred Estate (2009-2010) in Kennington, Lambeth.

Co-operative social housing

In London, the North Camden Housing Co-operative commissioned a deep retrofit of Carlton Chapel House to EnerPHit standards. The social housing block of 15 flats was built in the 1980s, and was later susceptible to energy losses, forcing residents into fuel poverty. Renovation took place in 2019, and required decanting tenants to temporary accommodation. Collaboration between the construction contractors and the architects was key to achieving airtightness. Residents reported improved air quality, thermal comfort, and less noise after moving back.

Rural retrofits

The guidance about older and traditional homes is often relevant for social homes in rural locations. Swaffham Prior Heat Network is the first of its kind in the UK, delivering a mix of ground source and air source communal heat to 300 homes, including residents at Sanctuary social homes. The project is the result of collaboration between the Swaffham Prior Community Land Trust, Cambridgeshire County Council and the Cambridgeshire and Peterborough Combined Authority.

Learning from examples

In seeking to bring new life to dysfunctional buildings, it pays to learn from other projects, including unforeseen challenges. Flagship retrofits such as the low rise flats at Erneley Close in Manchester (2015) and 11-storey housing blocks at Wilmcote House in Portsmouth (2014-2018) revealed structural issues while retrofits were under way. Such technical and financial complexities illustrate inherent risks to retrofitting homes that initial building surveys, however comprehensive, may fail to detect. Decanting residents or allowing them to stay in occupancy during retrofit works can both be a challenging experience. In both instances, however, residents reported significant improvements to living conditions after final completion.

Final Thoughts

The scale of the retrofit challenge is enormous. This does not mean starting from scratch, however. The wide range of projects cited in this article demonstrate that social housing retrofits can be delivered at scale for nearly all types of homes, apart from structurally unredeemable buildings. It pays, therefore, to learn, and lead, by example.

New life for old homes: the potential of retrofitting social housing

Posted on by

by Ian Babelon

How can social housing retrofits help tackle the cost-of-living and climate crises that are currently exercising the minds of landlords, householders, tenants and governments? In this, blog post, Ian Babelon looks at the potential of retrofits for making homes more energy efficient and for futureproofing the built environment.

The benefits and costs of retrofitting

Around 38% of all homes in the UK were built before 1946. As a result, the UK’s housing stock is not only the oldest, but among the most poorly insulated in Europe, leading to higher energy bills and a lower quality of life. At the same time, UK homes account for over 66m tonnes of direct carbon emissions, undermining government decarbonisation efforts.

On many different levels, making Britain’s housing more energy efficient makes sense. Estimates by the UK’s Department for Energy Security and Net Zero (DESNZ) suggest households could save £220-400 in energy bills per year. In addition, retrofitting homes can address fuel poverty, provide decent homes, reduce public health costs, and help deliver decarbonisation targets.

But energy efficiency requires investment. Insight shared by the Greener Futures Partnership shows that it could cost between £13,000 and £25,000 to bring a social home to EPC (energy performance certificate) band C. This does not take into account training and skills requirements to retrofit homes, nor the significant variations in property condition, fabric type, fluctuating costs of construction materials, retrofit design choices, scheduling of renovation works, and availability of construction labour with the right skills. Retrofitting social homes at scale therefore requires working on multiple fronts at the same time.

The cost of not retrofitting

The 2022 Cost of Living Crisis in Scotland report by the Scottish Government shows that as many as 35% of households in Scotland may be fuel poor. In England, figures for 2022 by DENSZ indicate that fuel poverty affects 13.4% of households.

The consequences of fuel poverty are wide-ranging. The annual cost of treating health conditions associated with cold, damp homes in England amounts to £1.3 billion. Poor housing also affects mental health, can impair children’s learning opportunities, and puts older people at greater risk of strokes and other severe health conditions.

A 2021 National Housing Federation report showed that the UK’s social rented sector has made great progress in tackling fuel poverty (64.3% of housing association homes already have an EPC rating of C or above). But the study also underlined how much more needs to be done. An additional £36bn of investment is required, said the report, to bring the remaining 39% of housing association homes up to a C rating, as well as installing heat pumps and other clean heat technologies in all 2.7 million homes.

Financing challenges and solutions

Social landlords also face significant costs for remediation and building safety improvements that hamper their efforts to retrofit homes and meet national energy efficiency targets. As DESNZ rolls out the second wave of the Social Housing Decarbonisation Fund, the NHF has called for long-term funding certainty so retrofits can pick up the pace.

Fortunately, more financing opportunities are becoming available for social landlords looking to make their properties more energy efficient, as reported in a report by the Green Finance Institute. These include local climate bonds, leaseholder finance and insurance-backed ‘comfort plans’, such as the Energiesprong approach, which can pay for insulation measures with energy and maintenance savings.

Fabric first…

It pays to insulate homes before investing in complementary measures such as renewable energy generation or smart technologies. This ‘fabric-first’ approach is an attractive alternative to the large up-front investment costs for deep, ‘whole-house’ retrofits that may be prohibitive for social housing landlords.

Incremental retrofit approaches can combine initial fabric improvement with scheduled upgrades, such as replacing gas with energy-efficient electric heating and hot water, installing air-source heat pumps (ASHP) or introducing smart home devices.

Strategic planning is essential to avoid piecemeal interventions that might prove more costly and less effective over time. The Social Housing Retrofits for the Future report commissioned by the Greener Futures Partnership highlights the need for cross-sectoral collaboration to tackle technical, financial, legal and customer engagement requirements simultaneously by providing extensive evidence from across Europe and the UK.

LETI, a volunteer network of over 1,000 built environment professionals, has published a Climate Emergency Retrofit Guide for use by social housing landlords, designers and contractors. The guide provides an engaging infographic overview as well as guidance for a range of home archetypes.

… Or building from scratch

Are all poorly performing homes worth retrofitting? So-called ‘hard-to-treat’ and ‘hard-to-decarbonise’ homes (about 2% of all social homes) can be very costly to upgrade. LETI provides a decision aid to determine whether one should retrofit or build anew, to be used in conjunction with other guidance.

A key aspect of this decision is to differentiate between embodied carbon (carbon emitted in making construction materials and during actual construction) and operational carbon (emissions produced during occupancy). All things considered, it is usually more worthwhile to renovate and reuse homes than to knock them down and redevelop them.

Beyond retrofitting

As performance increases to meet sector-wide energy-efficiency targets, designing for and monitoring air tightness will become increasingly important to help achieve decarbonisation.

High-performance standards such as Passivhaus ENERPHit are premised on sound air tightness and ventilation to guarantee thermal comfort while reducing energy costs. The Passivhaus Trust provides resources and case studies to help councils, ALMOs and housing associations deliver energy-efficient retrofits and new builds, along with a recent evidence-based research report that makes the case for whole-house, low-carbon retrofits.

The next frontier for retrofitting social housing at scale lies in neighbourhood-wide retrofits that could appeal even more to green finance but would require commensurate public-private partnerships and coordination.

Final thoughts

Overall, retrofitting social housing is a win-win for everyone involved. It is good for the environment, the economy, and the people who live in social housing. The up-front costs can be substantial, but the long-term benefits should make these investments cost-effective.

The social housing sector has clearly been taking action to deliver more energy efficient homes, and it’s working with residents, contractors, local authorities and other stakeholders to ensure that the Social Housing Decarbonisation Fund succeeds.

Challenges remain, notably concerns about skills shortages. But the prize of warmer homes, affordable energy, a better quality of life and a cleaner planet is well worth the effort of overcoming these obstacles.

Close to home: getting to net zero means decarbonising the UK’s housing stock

Posted on by
Photo by Erik Mclean on Unsplash

Two years ago, the UK became the first major economy in the world to pass a law pledging to bring all greenhouse gas emissions to net zero by 2050. Achieving net zero means balancing the amount of greenhouse gases we emit with the amount we remove, and it’s a critical factor in tackling climate change by reducing global warming.

But, according to the government’s independent adviser on tackling climate change, the UK will be unable to meet the net zero target without the near-complete elimination of greenhouse gas emissions from 29 million homes. 

The necessity: why buildings need to be decarbonised

In 2014, emissions from domestic properties accounted for 34% of total UK greenhouse gas emissions. A combination of high energy prices and improvements in energy efficiency brought that figure closer to 19%. But those reductions have stalled, and because the UK’s building stock is one of the oldest and most energy-inefficient in Europe, the need to decarbonise is even more urgent.

The benefits: environmental, health, economic

While achieving net zero is one good reason for making our buildings more energy efficient, decarbonisation offers further dividends.

Energy efficient homes are cheaper to run, reducing the levels of fuel poverty that affect millions of households. They can also bring health benefits in the form of healthy air temperatures, lower humidity, better noise levels, and improved air quality.

In addition, a nationwide programme of decarbonising buildings could make a vital contribution to the recovery of the economy from the coronavirus pandemic. A recent inquiry by the House of Commons Environmental Audit Committee  (EAC) found that investing in energy efficiency alone could create 34,000 full-time jobs within the next two years. In the longer term, energy efficiency investment could support an estimated 150,000 skilled and semi-skilled jobs to 2030.

The problems: high costs, skills uncertainty and a “disastrous” insulation scheme

The UK government says the cost of decarbonising homes is between £35 billion and £65 billion. But the EAC believes that this seriously underestimates the cost of upgrading the energy efficiency of homes. With 19 million homes in England requiring energy efficiency installations, this could cost £18,000 per home, even before the installation of a heat pump.

Another area of concern is skills. Brian Berry from the Federation of Master Builders told the committee that every tradesperson in the country needs to be upskilled in retrofit techniques in order to secure overall competency in the supply chain:

“We need to upskill people in the building industry because there is a need to understand how their skills interrelate to one another. You cannot just pick out one bit of this. It has to be seen holistically, which is why I think there needs to be a national retrofit strategy, a clear political direction and a commitment to reducing carbon emissions in our homes.”

The EAC was also outspoken in its criticism of the government’s flagship home insulation scheme. The Green Homes Grant was launched in 2020 to offer £1.5bn in subsidies for insulation and low-CO2 heating. However, only 6.3% of the money has been spent, despite exceptionally high demand.

The committee said the scheme was rushed and poorly implemented, and described its administration as “nothing short of disastrous.” Just six months after its launch, the scheme has now been scrapped. Instead, energy saving upgrades and low carbon heating will be delivered to homes through local authorities in England.

The recommendations: strategies, incentives and insights from overseas

There’s no shortage of suggestions for driving decarbonisation forward. The EAC has called for a government strategy for the next decade to give industry and tradespeople time to upskill and to give households the right signals to invest in energy efficiency. The committee also recommends that VAT on the labour element of refurbishment and renovations is reduced to 5%, a measure also supported by the Royal Institute of Chartered Surveyors.

It’s also worth looking at ideas from overseas. In February, research by the University of Edinburgh reviewed the heat decarbonisations policies in nine European countries. The report highlights particular progress made by the Nordic countries in decarbonising buildings’ heat supply and in making greater use of electricity as a potential future source of low-carbon heating.

The solutions: putting promises into practice

While the challenge of decarbonising homes may be daunting, a growing number of housing providers are taking steps to cut emissions from domestic properties.

The Welsh Government has provided £20m in funding for Optimised Retrofit. Through this scheme, 28 social landlords can retrofit homes and test the ways heat and energy are produced, stored and supplied. If it’s successful, the scheme could be the model for decarbonising all of Wales’ 1.4 million homes by 2050.

Last month, Sutton Council launched an energy-efficiency programme to transform draughty properties with high energy bills into net zero carbon houses which are warmer and cheaper for residents. The programme is based on a successful Dutch initiative known as Energiesprong (energy leap). In the Netherlands, 1300 net zero energy refurbishments have been completed, and a further 500 are being built. The initiative involves insulating the external walls and roof areas, replacing windows and doors and installing new solar panels to power a new central heating and ventilation system. Sutton is the first London borough and the latest UK housing provider to adopt the programme, which has already been taken up in Nottingham and Maldon.

Many housing associations are at the start of their journey to net zero, but a National Housing Federation survey has shown that two thirds of social housing landlords have started planning to make their homes greener and warmer. Three quarters (74%) of survey respondents expect to retrofit homes in 2020-21. A similar proportion (73%) expect to retrofit homes in 2021-22. However, the survey also reported that lack of finance and continuing policy uncertainty remain major obstacles to decarbonising homes. That’s important, particularly given the cost of decarbonisation of social housing – £104bn by 2050.

The future: decarbonisation begins at home

Local authorities, housing associations, and the construction industry are all keen to transform existing homes into greener, warmer places to live in. At the same time, residents – especially those having to make the choice between heating or eating – need to be taken out of fuel poverty. And, as we’ve seen, achieving net zero will only be possible by making the nation’s housing stock more energy efficient.

With so much riding on decarbonisation of domestic properties, the need for more funding as part of an ambitious policy approach is clear. As the UK prepares to host the critical climate change talks in Glasgow this year, there has to be a better understanding that tackling the climate emergency starts on our own doorstep.

Is this the future of social housing?

Goldsmith Street: Mikhail Riches / Tim Crocker 2019

Last year, a development of 105 homes on the outskirts of Norwich became the first social housing project to win the prestigious Royal Institute of British Architects Stirling Prize.

The Goldsmith Street estate was built by London architecture firm Mikhail Riches for Norwich City Council, and is the largest Passivhaus scheme in the UK. Passivhaus is an approach to building that provides a high level of occupant comfort while using very little energy for heating and cooling.

Goldsmith Street has been carefully thought through, and adjusted to take account of changing economic and environmental circumstances. In 2008, Norwich City Council selected Mikhail Riches to design the estate. The council had intended to sell the site to a local housing provider, but when the financial crash happened, the council decided to develop the site itself.

The architects have striven to ensure that the development acknowledges the historic context of the site:

“The design seeks to re-introduce streets and houses in an area of the city which is otherwise dominated by 20th century blocks of flats… Street widths are intentionally narrow at 14m, emulating the 19th century model.”

The homes themselves have been built to strict Passivhaus standards which include:

  • very high levels of insulation;
  • extremely high performance windows with insulated frames;
  • airtight building fabric;
  • ‘thermal bridge free’ construction;
  • a mechanical ventilation system with highly efficient heat recovery.

Passivhaus standards typically reduce heating energy consumption by up to 90% as compared to traditional housing. For residents in the Goldsmith Street development, heating bills should be about £150 a year.

Eco friendly housing

In recent years, local authorities and housing associations have been responding to the increasing demands for housing stock to have lower maintenance costs, lower energy costs and fewer emissions of carbon and other gases that can be harmful to the environment and human health.

The Passivhaus Trust has highlighted a growing number of local councils and housing associations that have been exploring Passivhaus standards as a way of tackling these issues.

One of the most ambitious social housing Passivhaus projects is Agar Grove in the London Borough of Camden. Previously a 1960s estate with an unenviable reputation, Agar Grove has been rebuilt with affordable and energy efficient homes. The first phase, involving 38 social rented homes was completed in 2018, and has already won awards for sustainability and community consultation. Once complete, the 500-home estate will be the largest Passivhaus development in the UK.

Cunningham House, Glasgow: Page\Park Architects

In Glasgow, the city’s first Passivhaus development for social rent was opened by Shettleston Housing Association in September 2019. The project provides nineteen new homes for older people in an innovative design that combines a five storey Passivhaus tower with a converted church building. All of the homes benefit from high levels of thermal insulation to augment the sandstone coat of the existing church structure. The project was named the best affordable housing development at the 2019 Inside Housing Awards.

Meanwhile, the City of York Council has released plans to build more than 600 homes across eight sites over the next five years that will be built to carbon zero standards. The council has pledged that 40% of the homes will be affordable, with 20% retained for social renting. The developments, also designed by Mikhail Riches, will have very high energy efficiency standards that exceed standard Passivhaus levels. It’s predicted that residents’ heating bills could be around £60 a year.

Homes for the future

There is a now a growing sense that housing, as well as consuming great amounts of energy, can also be a positive force for change. Energy efficient homes can make a strong contribution to climate change adaptation measures, can make housing more resilient to increasingly common extreme weather events, and can provide opportunities to improve economic development, quality of life and social equality.

In the past year, with many local councils, combined authorities, devolved administrations and the UK government declaring ‘climate emergencies’, the pressure on housing providers to lead by example has intensified. At the same time, governments are setting out plans to ensure new homes are more energy efficient.

The Ministry of Housing, Communities and Local Government is currently consulting on the Future Homes Standard, which includes proposals to increase energy efficiency requirements for new homes from 2025. Similarly, the Scottish Government plans to introduce new regulations to ensure all new homes use renewable or low carbon heating from 2024. A 2019 report commissioned by the Welsh Government has recommended major changes to most homes in the country, including a major programme to improve insulation and heating.

Goldsmith Street: Mikhail Riches / Tim Crocker 2019

The success and widespread publicity enjoyed by the Goldsmith Street project is likely to encourage other local authorities and housing associations to explore the possibilities of Passivhaus. But although the benefits are great, Passivhaus also presents significant challenges for housing providers.

Up-front costs are higher for Passivhaus developments, and there are additional maintenance and replacement costs. The technical requirements are strict, in order to ensure the maximum levels of airtightness and insulation. In addition, there is a shortage of skills needed to achieve the exceptional standards of construction demanded by Passivhaus (Norwich City Council has overcome this by bringing together a network of specialist contractors with the necessary expertise to work on Passivhaus projects).

Despite the challenges, Passivhaus seems to be offering a compelling answer to the significant problems of fuel poverty, climate change and the demand for high quality, affordable housing. As more local authorities and housing associations demonstrate its affordability, Passivhaus is breaking away from its image as a resource for the privileged and moving into the mainstream of social housing.

A mixed reception for Labour’s housing green paper

Posted on by

 

In April, the Labour Party launched its strategy for tackling the housing crisis in England. Housing for the Many presents a 50-point plan, with proposals that include:

  • investing £4bn a year to build one million ‘genuinely’ affordable homes over 10 years
  • lifting of council borrowing caps
  • removing the ‘viability loophole’, making it impossible for developers to dodge their affordable housing obligations
  • zero tolerance of developments without any affordable housing provision
  • a stricter definition of affordable housing
  • scrapping the ‘bedroom tax’
  • suspension of ‘right to buy’
  • cut-price government loans for housing associations
  • protected housing benefit for under 21s
  • consideration of mandatory space requirements
  • a new generation of garden cities and new towns

Following its publication, analysts in the housing and property sectors gave their thoughts on the strategy.

More affordable homes

The most ambitious proposal is the plan to build 100,000 homes each year.

For Emily Williams, associate director at Savills, this proposal was the most eyecatching:

“The emphasis on investing to deliver more homes to solve the housing crisis, rather than relying on housing benefit to support people who can’t access market housing, is something we have been talking about for a long time.”

However, Savills estimates that the £4bn figure is insufficient for Labour to hit its one million homes target, suggesting that a further £3bn would be needed.

Elsewhere, Carl Dyer, partner in Irwin Mitchell solicitors expressed concern about where the money would come from:

“After Labour’s last 13 years in power from 1997 to 2010, their out-going Chief Secretary to the Treasury famously left a note for his successor: “Sorry, there’s no money”. There is still no magic money tree, and no indication here how these homes are to be funded.”

Developers

Labour’s policy of no development without affordable housing has raised concerns in the property industry.  Justin Gaze, head of residential development at Knight Frank told Property Week that the proposals risked deterring developers from undertaking new projects:

“There will be instances where affordable housing cannot be provided, for example on conversions of some buildings where it’s difficult to deliver both open-market and affordable housing side by side.”

The land market

One of the less reported proposals caught the eye of Luke Murphy, IPPR’s associate director for the environment, housing and infrastructure. Writing in CityMetric, Murphy highlighted the proposal to create an English Sovereign Land Trust that would allow local authorities to buy land at cheaper prices to build affordable homes.

“It is here, through intervention in the land market, that the state could have the biggest impact – not to just build more affordable homes, but to make all new homes built more affordable.”

But he argued there was still room for improvement:

“… on land reform, there is scope to be bolder and go further to ensure that affordable housing really is available ‘for the many’, rather than the preserve of the few.

Redefining affordability

The Royal Institution of Chartered Surveyors (RICS) commented on Labour’s proposal to redefine affordable housing to relate it to average incomes rather than housing as a percentage of market rates:

“This makes sense as a measure of affordability, however, this will likely lead to a trade-off between affordability and the numbers of affordable homes delivered, unless capital grants are available at the outset, geared to the income segment to be accommodated.”

RICS also welcomed the plan to lift council housing borrowing caps.

“This is certainly something RICS has been calling for, however appropriate measures must be taken to ensure that local authorities do not expose themselves to too much risk.”

Benefits reforms

The Chartered Institute of Housing wondered whether Labour would reform the benefit system to bring it closer into alignment with housing policy:

“Of course, abolishing the bedroom tax will help, but tenants’ ability to pay their rent if they are on low incomes is now under assault from the whole range of welfare reforms, of which bedroom tax is only one.”

Final thoughts

The housing crisis has been decades in the making, and there is no quick fix for tackling the problems of housing shortages, affordability and homelessness. Just last month, research by Heriot-Watt University found the chronic shortage of housing in the UK was greater than first thought, amounting to four million homes. To meet the backlog, the researchers estimated that the country needs to build 340,000 homes a year until 2031. This is significantly higher than the targets set both by the Conservative government and the Labour Party.

The new green paper from Labour has presented clear alternatives to the government’s housing policies, and later this year the government is set to publish its own green paper on social housing. The debate will continue, and housing will remain high on the political agenda.

Housing matters: our recent publications cover issues from homelessness to housing and health

Posted on by

tiny houses 4

By Heather Cameron

The Chartered Institute of Housing (CIH) annual conference and exhibition, the largest housing-focused event in Europe, takes place this week. Over the next three days the conference will examine and explore the political and policy environment, the economic outlook and the latest thinking across the sector.

A variety of topics will be addressed, including housing supply, housing policy, social housing, welfare reform, regeneration and homelessness. These topic areas feature extensively on our database, some of which we have also written about. So this is a good opportunity to highlight some of our recent publications in this area.

What we’ve published

Our most recent ‘In focus’ briefing looks at housing retrofitting, something that has been highlighted as essential for improving the energy efficiency of our housing stock. It considers the benefits of renovating domestic properties to improve energy efficiency and environmental performance and describes the features and technologies of retrofit, such as heat pumps, combined heat and power and various types of insulation. The environmental, economic and social benefits as well as the barriers are summarised. Recent developments concerning retrofit schemes introduced by the UK government and the devolved administrations are also described, and there are examples of good practice from the Netherlands, Sweden and the UK.

Last month we published Delivering solutions to tackle homelessness (Ideas in practice), which looks at the scale of homelessness across the UK and its causes, and provides innovative examples of projects and initiatives that are tackling the problem.

The examples of innovative approaches highlighted include:

We have also written a series of blogs on the topic of homelessness. These include a look at the Christmas Dinner campaign for the homeless run by Scotland’s not-for-profit sandwich shop, Social Bite, while also highlighting the recent increase in homelessness in Scotland and the UK, and the shocking number of homeless children at Christmas.

Another blog post looks at the problem of the hidden homeless and its financial and human costs.

Digital inclusion and the social housing sector is the topic of another ‘In focus’ briefing. This looks at the benefits of digital inclusion, the barriers to digital inclusion for social housing tenants, and how these might be overcome. It refers to a 2012 report which found that almost half of the UK’s adult population who do not use the internet live in social housing, suggesting digital exclusion is a particular problem in the sector. It includes examples of good practice and highlights the importance of digital inclusion in the context of welfare reform.

We also recently blogged on this topic, highlighting one of the examples of best practice featured in our briefing: a case study of a collaboration between Reading Room – a digital consultancy which joined the Idox Group in 2015 – and Catalyst, one of the leading housing associations in London and the South East. This collaboration highlights the potential of technology for improving communications between social housing providers and their tenants, and for encouraging more people to reap the benefits of going online.

Another topic we have looked at is the integration between housing and health. Housing conditions can affect the physical and mental health of people, and can contribute to many preventable diseases and injuries. The ageing population is also putting pressure on the NHS, and growing numbers of older people have to stay in hospital longer because their homes are unsuitable for their recovery. Our briefing notes that housing associations, local authorities and healthcare providers have been working on solutions to tackle these challenges, and provides case studies from London, Tyneside and Bristol as examples of greater collaboration between housing and health services.

The challenges of an ageing population for the housing sector has also been highlighted in our briefing on meeting the housing needs of older people. It indicates that there will be a need for: adaptations to existing housing stock; mainstream rented accommodation built to accommodate wheelchair users; and newly built specialist accommodation. Examples of good practice – including case studies of extra care housing from Calderdale Council, and adapting homes for older and disabled residents in Knowsley, Merseyside – are highlighted.

This is just a flavour of what we’ve recently covered on housing-related topics, and we will inevitably produce more as the sector responds to a time of change and uncertainty.

Some of our briefings are only available to members of the Idox Information Service.

Rebuilding a community without bringing down the house: an alternative to demolishing ‘sink estates’

Posted on by

In January, the prime minister outlined plans for a £140m development programme in England that he said would improve the life chances of the most disadvantaged people living in social housing estates with high levels of deprivation.

“A new Advisory Panel will help galvanise our efforts and their first job will be to build a list of post-war estates across the country that are ripe for re-development, and work with up to 100,000 residents to put together regeneration plans. For some, this will simply mean knocking them down and starting again. For others, it might mean changes to layout, upgrading facilities and improving local road and transport links.”

The proposal received a mixed response. Some commentators observed that demolishing the worst “sink estates” built during the 1960s and 1970s would free up much-needed land for new homes. Elsewhere, the head of the ResPublica think tank welcomed the chance to replace ugly estates with more attractive environments

Others criticised David Cameron’s idea as a form of “social cleansing”, claiming it raised the spectres of privatisation and gentrification. And Councillor Richard Lewis, executive member for regeneration, transport and planning on Leeds City Council challenged the prime minister’s view that the problem of ‘sink estates’ could be resolved by demolition.

“Through careful management of our housing funds and rental income we have managed to make significant investment in council housing. “I simply don’t recognise the language of ‘sink’ estates when it comes to Leeds and I don’t think we should write off entire areas and the people that live in them.”

After the storm, a dramatic turnaround

A recent New York Times report echoed the view that renovation of deteriorating housing estates can be more effective than demolition. The article reported on a 1970s housing estate on Long Island that had gone into decline after years of neglect. Crime, drugs and vermin were just some of the problems associated with the crumbling properties of the estate. Things got a great deal worse when Hurricane Sandy stormed into the estate in 2012, flooding many of the apartments and cutting off power and fresh water supplies.

The obvious next step would have been demolition. But instead of being torn down, the estate has undergone a remarkable transformation that astonished the newspaper’s reporter:

“The place is almost unrecognisable. Apartments are occupied once again. Hallways, kitchens, bathrooms and electrical systems are refurbished; lobbies opened up with big windows; a floodwall installed; the landscaping upgraded, with a broad promenade to the beach; and leaky facades clad with new, waterproof, energy-efficient panels. Energy bills have dropped 30 percent.”

The turnaround is thanks to a partnership between developers, government and the local community. The new owners renovated the estate at a cost of $60m, but avoided having to raise the rents of longstanding tenants through subsidies from the federal government. The improvements raised property values, enabling the developers to rent out vacant apartments at market rates.

Lessons from Long Island

As in London, there is a severe shortage of affordable housing in New York City. And – also as in London – subsidised public housing has largely given way to private developments for the super-rich. The New York Times reporter described the changes in his own neighbourhood of Greenwich Village, and other parts of New York that were once home to low- and moderate-income residents:

“Now the Village is like a gated playground for runaway wealth. Subsidised apartments all across town are converting to market-rate rentals and condos faster than City Hall can build affordable units or preserve old ones. The city Housing Authority is broke. Its ageing properties face $17 billion in capital repairs.”

Some key factors played a part in the transformation of the Long Island estate:

  • Private development was made possible through tax incentives and other publicly financed programmes
  • The developers consulted a sceptical local community, earning its trust and building consensus
  • On-site management teams maintained oversight of the renovation project
  • Design features to save energy, improve the neighbourhood and enhance quality of life were built into the renovation process

Final thoughts

The $60m price tag for renovating a single estate in New York City suggests that the £140m earmarked for regenerating England’s 100 worst “sink estates” won’t be nearly enough, and may even have been downgraded. A month after the prime minister’s announcement, it emerged that the money set aside for the project will only be available in loan form to private sector developers.

And a warning of how badly off course the prime minister’s plan could go came from The Independent, which highlighted London’s Heygate Estate:

“Formerly one of the largest social housing projects in Europe it was home to thousands, a large number of whom disagreed with its nefarious depiction as problematic sink estate. Widely praised for its green spaces and innovative architectural design, many argued in favour of its refurbishment, but it was nevertheless ‘decanted’ and finally demolished last year to make way for largely private apartments.”

Perhaps addressing the needs of declining housing estates requires a more constructive approach than bringing in the wrecking ball.

Hoarding and housing: person-centred approaches to a growing problem

Posted on by

Most people have possessions in their homes that they can’t bring themselves to throw out, from clothes and furniture to photographs, books and ornaments. But the growth of clutter around the house can sometimes escalate to become so severe that it causes significant risks to the health and wellbeing of residents and their neighbours.

For housing providers, problematic hoarding has become a serious and costly issue. In 2014, Inside Housing magazine reported an increase in the number of social housing landlords seeking injunctions to inspect homes where they suspected the resident of hoarding. But a housing management solicitor highlighted underlying difficulties with taking legal action against problematic hoarders.

“Even if the housing association wins and costs are awarded against the tenant, the chances of the tenant paying are slim. It’s a problem because it’s a huge expense.’

The nature of hoarding

A 2012 paper from the Chartered Institute of Environmental Health (CIEH) provided an overview of hoarding, and observed:

“As a behaviour, it is quite common and most people who hoard possessions do not suffer from any psychiatric disorder. However, in some cases the problem may progress to become so severe that it causes significant distress and impairment.”

The CIEH paper noted that three components have been identified with problematic hoarding:

  • acquisition of and failure to discard possessions that appear to be of little use or value
  • living spaces sufficiently cluttered so as to preclude activities for which those spaces were designed
  • significant distress or impairment in functioning caused by the hoarding

The problems and risks for housing providers and their tenants

For housing providers, residents and neighbours, hoarding presents particular problems and risks, including:

  • overcrowding issues
  • health and safety hazards, including fire risks and falling /tripping
  • environmental health concerns, including infestation and vermin
  • properties falling into disrepair

Tackling the problem

Under mental health and environmental legislation, local authorities and health agencies can take action where hoarding constitutes a statutory nuisance or health and safety risk. Social landlords may also resort to legal action against tenants. But taking an enforcement-only approach raises tricky ethical questions, especially if a resident is mentally unwell. And, as the Inside Housing article reported, taking tenants to court can be ineffective and expensive. Housing organisations, therefore, are increasingly developing person-centred approaches to help compulsive hoarders understand and change their behaviour.

Orbit Housing: support and advice

For some years, the Orbit housing group has been collaborating with Coventry University and the Knowledge Transfer Partnership to tackle the growing problem of hoarding.

In 2013, Orbit launched a toolkit designed to support practitioners and organisations working with people who compulsively hoard. The toolkit was developed with input from mental health support organisations, environmental health bodies and service users. It addresses environmental and social isolation issues and includes advice on the assessment process, intervention tools, improvement measures, relapse prevention, and sign-posting.

In 2015, Orbit obtained funding for two specialist case workers, enabling the launch of a new hoarding support and advice service. In addition, Orbit has also developed a hoarding policy setting out the aims, principles and values to be adopted in the housing group’s approach to individuals with hoarding tendencies.

Derbyshire:  Vulnerable Adult at Risk Management

Because problematic hoarding can require responses from different agencies, including social housing providers, environmental health and fire and rescue services, a multi-agency approach is helpful in tackling the issue.

In Derbyshire, this kind of multi-agency policy has been established to develop a risk management plan for people who would not necessarily fall into the responsibility of adult social care direct service provision.

Vulnerable Adult at Risk Management (VARM) is managed by Derbyshire County Council and Derby City Council, with support from the Fire and Rescue Service, police, social housing providers, environmental health and others. The policy aims to support vulnerable adults who are at risk of serious harm through self-neglect and risk-taking behaviour, and it has already been applied in cases of hoarding.

Last year, the Chief Fire Officers’ Association highlighted a case where the VARM policy helped a Derbyshire social housing provider to support an elderly man who was putting himself at risk due to hoarding behaviour.

“His care package was adjusted, to include assistance with household chores; he was visited and helped by health practitioners; his home was cleared allowing his central heating to be repaired. Fire risks were mitigated down to an acceptable level without the need to revisit and upset him.”

Similar approaches have been developed by Circle Housing Association in the London borough of Merton, and by Knightstone Housing in the West of England.

Positive outcomes

Hoarding is one of many resource-intensive problems facing social housing landlords. But, as these examples demonstrate, a collaborative, sensitive and supportive approach to problematic hoarding can achieve positive outcomes for housing organisations and their tenants.

Digital inclusion in practice: how Reading Room is helping social housing tenants go online

Posted on by

IMG_20160120_101616

In 2012, a Housing Technology report found that almost half of the UK’s adult population who do not use the internet live in social housing. The report’s contributors (including the Chartered Institute of Housing, the National Housing Federation and Peabody housing association) argued that digital inclusion gives tenants more choice and control and better access to lower-cost, better services.

For housing associations, the impact of developing a digital strategy to engage with their tenants can be substantial. The report estimated that social housing landlords could achieve annual savings of £340m in communications costs.

The benefits of digital inclusion for social housing landlords and their tenants is explored further in the latest “In focus” briefing from The Knowledge Exchange.

Social housing: the digital revolution

Increasingly, social housing providers and tenants are connecting online through media such as Facebook, Twitter and online chat services. Other housing associations are offering interactive features on their websites, enabling tenants to check their rent accounts or to book appointments.

But, as the Housing Technology report showed, significant numbers of people don’t have online access. For some, it’s a matter of poor broadband coverage, while others have concerns about access costs and data security.

Our briefing includes examples of how social tenants and their housing providers can benefit from greater digital inclusion, and highlights ways in which the barriers to going online may be overcome.

Reading Room and Catalyst:

Among the examples of best practice featured in the briefing is a case study of a collaboration between Reading Room – a digital consultancy which joined the Idox Group in 2015 – and Catalyst, one of the leading housing associations in London and the South East.

Reading Room has worked closely with Catalyst and its customers to create a strategic framework for the housing association’s digital development. Among the themes emerging from this framework are projects for:

  • Optimising Catalyst’s web platforms for mobile devices and making them more user friendly
  • Developing a plan to implement new online services
  • Training and developing internal teams with digital best practices, including content creation and customer service through social media
  • Engaging the business and creating a team of digital champions
  • Embarking on an innovation programme towards building smart homes

Once the work is complete, Catalyst customers will be able to report and track issues directly through a new web platform, while contractors can view available jobs and location data.

Future plans

Further down the line, Reading Room and Catalyst are working on plans to use the Internet of Things to create smarter buildings with sensors that can detect changes before they become problems, notify the repair company and update the customer automatically.

The collaboration between Reading Room and Catalyst highlights the exciting potential of technology for improving communications between social housing providers and their tenants, and for encouraging more people to reap the benefits of going online.
