Tourism – is it “killing neighbourhoods”?

deck chairs at the seaside

By Heather Cameron

Today is World Tourism Day (WTD), the aim of which is “to foster awareness among the international community of the importance of tourism and its social, cultural, political and economic value.”  (United Nations)

Commencing on 27 September 1980, WTD is celebrated each year with fitting events based on themes selected by the United Nations World Tourism Organisation (UNWTO) General Assembly. The theme for 2017 is the International Year of Sustainable Tourism for Development. The UNWTO says tourism can contribute to all three dimensions of sustainable development – economic, social and environmental – as well as the 17 UN sustainable development goals. It argues that in addition to driving growth, the tourism sector also improves the quality of people’s lives.

However, a recent wave of anti-tourism protests across Europe suggests some disagree.

Anti-tourism sentiment

Much of the focus of anti-tourist sentiment during the summer has been in Spain, where a record 75 million foreign tourists visited last year – up 10 million on 2015. Catalonia hosted more visitors than any other. Estimates suggest an extra 30 million people descended on Barcelona, where radical groups have been reported slashing tyres of rental bikes and a tour bus. The tour bus was also reportedly adorned with the slogan “tourism is killing neighbourhoods.

As the number of tourists has been growing exponentially, so too have the tensions over this surge, coupled with the impact of holiday lets on the local housing market and thus local communities.

Majorca has also experienced protests from citizens against mass tourism. Here concerns have been raised over the number of drunken visitors and the rental of apartments to non-locals, reducing the number of places for locals to live and driving up house prices.

Rising rents and the impact on the environment have been cited as of particular concern among local communities.

Social and environmental impacts

Such concern is by no means a new phenomenon.

A 2012 report on the impacts of tourism on society found that while tourism generates both wealth and jobs, it has also been seen to have negative impacts on socio-cultural values and environmental assets of host communities.

At the same time as bringing people from different backgrounds, cultures and traditions together, due to globalisation, it is argued, tourism has led to many communities losing their cultural identity and giving way to a ‘Disneyfication’ of their town or village.

And while tourism has contributed to the creation of national parks and protected areas, it has also been blamed for increased pollution. According to the United Nations Environment Programme (UNEP), the three main environmental issues of tourism are the depletion of natural resources, pollution and physical degradation.

It is suggested that the main problem emanating from these impacts is that the host community picks up the tab for any damages to the environment and local culture.

Tourism clearly generates a variety of consequences, both positive and negative. It is therefore something that requires careful management.  As the 2012 report concludes, “Tourism development should be part of an economic development and must be done in a manner that is sustainable.”

Sustainable tourism

The focus of this year’s World Tourism Day therefore seems particularly apt. As the World Travel and Tourism Council (WTTC) has highlighted, this provides a unique opportunity for travel and tourism to come together to address the challenges set out in the UN’s sustainable development goals, and for the sector to address the issues of climate change, physical degradation and disruption that leaders from both inside and outside of tourism consider to be of the highest priority.

Progress has certainly been made, as the WTTC has reported:

  • travel and tourism companies were 20% more carbon efficient in 2015 than they were in 2005;
  • the sector is on course to reach a target of cutting CO2 emissions by 50% by 2035; and
  • the sector is on course to reach the target of 25% reduction by 2020.

However, as the recent anti-tourism sentiment indicates, more needs to be done to manage growth in a sustainable manner.

Final thoughts

Sustainable planning and management is clearly important to ensure the long-term viability of the tourism industry. And as the sector represents 10.2% of global GDP and supports 1 in 10 jobs globally, it is too important not to get right.

Designing for positive behaviours

St Paul's Cathedral, London, England

By Heather Cameron

“We shape our buildings; thereafter they shape us” – Winston Churchill, 1943

This much borrowed saying from the former prime minister was made during the 1943 debate over the rebuilding of the House of Commons following its bombing during the Blitz. Although many were in favour of expanding the building to accommodate the greater number of MPs, Churchill insisted he would like it restored to its old form, convenience and dignity. He believed that the shape of the old Chamber was responsible for the two-party system which is the essence of British parliamentary democracy.

Indeed, it has since been widely acknowledged that the built environment has a direct impact on the way we live and work, thus affecting our health, wellbeing and productivity. A new report from the Design Commission, which opens with Churchill’s statement, is described as “a very valuable contribution” to the debate on how the design of the built environment can influence the way people think and behave, “making a healthier, happier and more prosperous and sustainable country”.

Impact of design

The report, which follows a year-long inquiry, is described as providing “solid evidence in difficult areas” on what it is in the built environment that makes people’s lives better. Evidence was gathered on four specific areas believed to be the most important to national policy:

  • health and wellbeing
  • environmental sustainability
  • social cohesion
  • innovation and productivity

It is suggested that design acts at two levels: it can affect individual choices of behaviour, which can then affect health and sustainability; and it can affect the way people are brought together or kept apart, which can then affect communication and creativity, or social cohesion.

The inquiry therefore looked into how people’s behaviour, health and wellbeing are affected by their surroundings; the role design can play in encouraging environmentally sustainable behaviours; the role design can play in social cohesion through its effects on creating or inhibiting co-presence in space; and how the design of work environments can drive innovation and improve efficiency, therefore tackling the current ‘productivity crisis’.

The evidence

The evidence highlights the built environment as “a major contributing factor to public health”. A range of public health issues, including air pollution and obesity, were suggested to be directly linked to factors within the built environment. Other recent research has similarly highlighted this link between health and urban design.

Evidence of the potential for design to positively influence sustainability behaviours, such as greater cycling and walking activity, was also highlighted, with New York cited as a good practice example.

Providing evidence on social cohesion, a senior university lecturer stated that “to divorce the physical from the social environment is inappropriate”. Other submissions referred to the “alienating effects” of various aspects of modern corporate life on civic participation, including estate management, crime and safety, the perceived negative impacts of poorly-conceived urban planning and poor or no maintenance.

Well-designed places, on the other hand, are suggested to improve access and facilitate social cohesion. Nevertheless, the evidence also noted that regardless of how well designed a place may be, “neglecting its aftercare will lead to antisocial behaviour and environmental damage.”

The relationship between the built environment and productive behaviours is supported by substantial evidence, according to the report. In the context of the UK, a lack of access to daylight and fresh air is cited as a reason for offices failing to get the best out of their workers. One study cited, indicated an increase in levels of both wellbeing and productivity in office environments with so-called ‘natural elements’.

Policy – “muddled and fragmented”

While there is evidence of good practice throughout the UK, a principal argument from the report is that more needs to be done.

Policy making for the built environment has traditionally been “muddled and fragmented”, according to the report. It suggests that there is a lack of understanding of the significance of the influence of the built environment on behaviour among policy makers at all levels and therefore makes recommendations for central government, local government and the private sector.

It argues that the relationship between government and local authorities requires reconsideration, calling for greater power at local government level.

Despite encouraging steps with regard to devolution in positively impacting behaviour and quality outcomes, such as in London, it is suggested that more can be done in terms of better collaboration between all stakeholders.

It is also noted that as national policy will be now be conducted in the context of Brexit, adaptation of the regulatory regime will be required.

Final thoughts

The key message from the Design Commission’s inquiry is evidently that the design of the built environment is particularly important in the context of current challenging times for the UK:

 “The way we design our built environment could be one of our greatest strengths in navigating the course ahead… If we get this right, we can build a Britain that is healthier, happier and more productive.”

Managing growth in historic towns

canterbury cathedral

By Heather Cameron

Predominantly set within environmentally attractive surroundings, historic towns and cities have a strong sense of place, offer a good quality of life, are often prosperous and represent models of sustainable development.

Research shows that businesses based in older places are more productive than the average for all commercial businesses across the whole economy. Retail and leisure businesses often seek to cluster in historic areas of towns and cities, and historic buildings are particularly attractive to new business start-ups, especially in the creative and cultural sector. Well-maintained historic places also enhance cultural life and community resilience.

As a result, historic towns are much sought after places to live and work, which has contributed to unprecedented growth.

Growth pressures

While growth is seen as a good thing for the future of town centres, managing it effectively in these areas of historic importance is not without its challenges. Older townscapes and buildings are a valuable and irreplaceable community asset that need to be protected.

Growth in historic towns creates pressure for new housing and development, and the infrastructure that is needed alongside it. It can also lead to increased congestion and depletion of suburban quality through redevelopment and loss of garden space. The traditional infrastructure in these towns may not be able cope with the increased capacity resulting in demand for suitable adaptation.

Managing these growth pressures is a particular challenge for historic towns as they need to try and meet local development need while both conserving the identity and sense of place of the existing town and nurturing the creation of sustainable new communities within them.

The Historic Towns Forum has highlighted that “there are challenges of infrastructure, partnership working, working with major national developers, the tension between modernity and pastiche and how to learn from the past and the present when building at this scale.”

In addition, the main political priority across all areas is economic wellbeing, taking precedence over any heritage considerations. A report from Green Balance in 2014 found that this principle concern was interpreted differently from place to place, with some local councillors viewing heritage as beneficial to a town’s economic and social wellbeing, while others viewed it is a burden and drag on investment.

As the heritage of places can be a particular pull for tourism, not preserving them could lead to a loss in economic wellbeing. The importance of achieving the right balance between sustainable development and heritage conservation is a theme that has been consistently highlighted in the research.

Smarter growth

So how do such places manage growth while also safeguarding both the character of the towns themselves and the settings around them?

According to the Historic Towns Forum, key issues in effectively addressing growth pressures in historic towns include:

  • planning and process;
  • partnerships;
  • finance and economics;
  • climate change;
  • community benefits and community engagement;
  • design; and
  • learning from the past and present.

It has been argued that a strategic approach to growth needs to be taken, such as the approach taken in Cambridge, where the Cambridgeshire Quality Charter for Growth is being used to help steer the creation of high quality sustainable communities.

Partnerships involving a range of local stakeholders, encompassing a shared vision and cooperation are also important for effective growth. Where strategic resources are lacking, which is often the case in smaller towns, community engagement can be of particular importance, as shown in Cirencester.

Key principles of good design have been highlighted to include:

  • learning from the past, including study of appropriate models;
  • localising by understanding local conditions; and
  • transforming action by applying appropriate, robust advances.

The overarching message seems to be that ‘smarter growth’ is required.

Good practice

There are examples of good practice where historic towns are managing growth in a way that protects their heritage. Cambridge, as mentioned previously, is one example. Sutton is another, where the challenges of growth are being addressed through the use of a Heritage Action Zone. The aim here is to balance growth with the management of heritage assets, providing lessons for elsewhere.

It is also important to look further afield. The historic town of Amersfoort in the Netherlands has been presented as a good model for managing housing growth to achieve attractive new settlements and create balanced communities. It has been suggested that this smarter approach is something that historic towns in the UK can learn from.

Another good example is Freiburg in Germany. Although different in terms of development to Britain, some of the issues applicable to British towns and cities have been addressed – including how to attract families to live at higher densities close enough to city centres to avoid car dependency.

As Historic England states:

“Learning is central to sustaining the historic environment. It raises people’s awareness and understanding of their heritage, including the varied ways in which its values are perceived by different generations and communities. It encourages informed and active participation in caring for the historic environment.”

ReGen Villages: is this the future of sustainable living? 

0031

‘Illustration © EFFEKT’

The Netherlands covers an area of 41,543 km², and has a population of 17 million people. That works out at 488 people per square kilometre, making Holland the most densely populated country in the European Union. By comparison, the UK has a population density of 413 people per sq km, while the figure for Scotland is just 68 people per sq km

Statistics like that matter when it comes to waste management. Lack of space in the Netherlands has prompted successive governments to divert waste from landfill, and encourage more recycling. The waste management movement was strongly influenced by Ad Lansink, a chemistry lecturer turned politician, who developed “Lansink’s Ladder”. This tool has six “rungs”, with disposal on the bottom, then recovery, recycling, reuse and on the top rung prevention.

The Dutch approach has reaped impressive benefits, with high rates of recycling and most of the remainder being incinerated to generate electricity and heat.

However, there is a growing sense that recycling in the Netherlands may be close to its limit. In 2015, Green Growth in the Netherlands reported that since 2000, the percentage of recycled waste has remained more or less constant.

“Recycled material reached 81% in 2012, a high share that has been fairly constant over the years. This may indicate that the recycling percentages are close to their achievable maximum.”

The Dutch are now looking for further ways to create more value from recycled waste.

ReGen Villages

One such idea is the development of  “regenerative villages” (ReGen). These self-reliant communities will produce their own food, generate their own energy and recycle their own waste.

The ReGen model is the brainchild of California-based ReGen Villages, which is partnering with EFFEKT, a Danish architecture practice, to launch a pilot version in the Netherlands this year. 

Each ReGen community will contain a variety of homes, greenhouses and public buildings, with built-in sustainable features, such as solar power, communal fruit and vegetable gardens and shared water and waste management systems.  The five principles underpinning the concept are:

  • energy positive homes,
  • door-step high-yield organic food production,
  • mixed renewable energy and storage,
  • water and waste recycling,
  • empowerment of local communities

The first 25 pilot prefabricated homes will be located at Almere in the west of Holland. Almere has experienced exponential growth, rising from farmland in the 1970s to become the seventh largest city in the Netherlands.

Waste management is a key element in the ReGen villages, which will have  ‘closed-loop’ waste-to-resource systems that turn waste into energy.

Prospects and problems

There are plans to roll out the model in other communities, in Europe, North America and the Middle East. Off-grid communities are not a new idea. But the necessary technology, falling costs and consumer demand have reached a point where the ReGen approach may become truly sustainable. The idea offers the promise of meeting the challenges of rising populations making unprecedented demands on limited resources.

Interviewed in The Guardian, Frank Suurenbroek, professor of urban transformation at the Amsterdam University of Applied Sciences, acknowledged the need for such projects, but also highlighted potential problems:

“A possible field of tension is how the technological demands of sustainability and circularity [interact with] spatial configurations needed to create attractive places and the desire to create new houses fast. Both worlds have to learn how to connect. Experiments with new sustainable quarters are interesting and needed, but a major issue is how to do this within existing built areas.”

All eyes on Almere

Once the first 25 homes are built, a further 75 will complete the village. It will take a lot of time, money, skill and muscle to make the project a success . We’ll be watching with interest to see if the vision can be turned into reality.

English Planning in Crisis: new ideas to recapture the purpose of planning in England

Housing estate iStock_000004526499Medium

“Essentially, the values of planning have been stood on their head, to the point where we have to ask whether the system remains fit for purpose.”

This is the stark assessment from the authors of a new book from Policy Press. In English Planning in Crisis, Hugh Ellison and Kate Henderson reflect on planning reforms since 2010, and argue that “the rich Utopian tradition that underpinned the town planning movement in England is dead, and needs wholesale recreation.”

The importance of planning

English Planning in Crisis highlights how essential planning is to the quality of life, noting that some of its key achievements have included securing mixed-use developments, the provision of social and genuinely affordable homes and protecting some of England’s most important landscapes. At its best, the authors contend, planning can provide for rich habitats and green space, good quality design, inclusion and resilience. But now, they argue, the once visionary town planning movement has become “little more than a residual form of land licensing.”

Reform and decline

The authors acknowledge that the decline of planning in England did not start in 2010. But they reserve particular criticism for the deregulation of policy on planning, housing and the built environment introduced under the coalition and Conservative governments.

Among the reforms in their sights are the withdrawal of the Code for Sustainable Homes, which had allowed councils to adopt their own sustainability levels as a planning requirement for new residential development, and the Deregulation Act 2015, which removed local planning authorities’ powers concerning construction, layout or energy performance of new dwellings.

There is also concern about extending the Right to Buy to 1.3 million housing association tenants, which the authors say has the potential “to transform socially and economically diverse communities into exclusively wealthy ones.” Similarly, they contend that the Conservative government’s Starter Homes policy (offering new-build houses at a price below their market value) will largely be of help to high earners.

Taken together, according to the book’s authors, reforms introduced since 2010 have resulted in a planning system that delivers poor-quality places, badly-designed dwellings, houses that are affordable only to middle and high-income earners, and ignores the challenges of climate change and an ageing population.

Planning beyond England

Before putting forward their ideas for rethinking the planning system in England, the authors look at planning systems elsewhere. They suggest that approaches adopted in Wales and Scotland provide pointers to how the English planning system can get back on track. They are particularly complimentary about Scotland’s framework for the spatial development of the country as a whole, which they suggest provides certainty and long-term thinking about planning. The authors also praise two regeneration initiatives in the city of Hamburg which have transformed derelict land into sources of renewable energy.

Ten steps to rebuild planning

The second half of English Planning in Crisis sets out a collection of evidence-based ideas for rebuilding England’s planning system. These include:

  • Replacing the current fragmented approach to planning for the future with a clear vision
  • Establishing a government department for spatial planning
  • Engaging with communities and individuals to develop solutions to the nation’s problems
  • Transforming the planning profession from an “old boys club” into a new generation of diverse and inclusive placemakers
  • Reform of planning education
  • A framework of equal rights in planning decisions
  • A national debate on house-building
  • Ensuring new homes are accessible for the elderly and disabled
  • Delivering sustainable homes, including a new zero-carbon policy
  • Fair taxation of land values.

The authors stress that these proposals are underpinned by the values of the Utopian tradition that inspired examples of planning at its best, including garden cities and the 1947 Town Planning Act. These values include social justice, fair rights to participate in decisions, and the fair distribution of resources arising from the development of land and primary resources.

In conclusion, the authors of English Planning in Crisis argue that only by reclaiming those essential values can England’s planning system recapture its purpose:

“Our future depends on the discovery of those democratic and altruistic qualities that once formed the ethos of town planning.”

Creating inclusive, prosperous places to live

by Heather Cameron

What does quality of life and ‘a good place to live’ mean? What are the key challenges to ensure quality of life in cities today? How can we create better places to live and who needs to be involved? These were just some of the questions explored at a seminar hosted by Policy Scotland, Glasgow University’s research and knowledge exchange hub, last month.

Running the event was Dr Georgiana Varna, Research Fellow at Glasgow University. Georgiana is a multidisciplinary scholar, specialising in urban regeneration and public space development.

Cities back on the agenda

A particular emphasis was placed on the importance of both place and people. Georgiana noted that cities are very much back on the policy agenda as we try to fix the mistakes of the 60s and 70s. She alluded to the New Urban Agenda, which embodies three guiding principles:

  • Leave no one behind
  • Achieve sustainable and inclusive urban prosperity
  • Foster ecological and resilient cities and human settlements

Following Georgiana’s introduction, several short presentations were given by a range of professionals and scholars.

Speaker: Michael Gray, Housing and Regeneration Services, Glasgow City Council

Michael Gray of Glasgow City Council delivered the first of the presentations, focusing on the Commonwealth Games Athlete’s Village in the East End of Glasgow. There was a clear pride in what they achieved with a belief that the result is a sustainable, cohesive community.

Michael did allude to some concerns that have been highlighted by GoWell East surveys regarding speeding vehicles, lack of buses and lack of local retail. But he also noted that lessons have been learned from the project, which was very complex in terms of procurement, design and construction, and that future development is addressing such concerns.

Speaker: Keith Kintrea, Glasgow University

Keith referred to Scotland’s standings in the PISA survey, showing that maths, reading and science achievement in Scotland sits in the middle and ahead of England, despite their efforts to improve. However, he noted that there is no room for complacency as those children in the most deprived areas were less likely to do well – nearly 70% of Glasgow pupils live in the most deprived areas.

Again, the importance of neighbourhood/place was emphasised, this time for local educational outcomes. It was noted that while Scottish schools are less segregated than the rest of the UK and more inclusive according to the OECD, (similar to countries such as Finland), this is not necessarily the case in cities. Keith concluded that we need to do much more about what places do in terms of educational outcomes.

Speaker: George Eckton, COSLA/SUSTRANS

George highlighted the importance of transport for delivering social, economic and environmental initiatives, and for growth in city-regions. Inequality in social mobility was put down to inadequate transport and it was noted that many people are disadvantaged in the labour market due to lack of mobility.

He stressed the need to increase the use of sustainable transport and argued that a collaborative approach will be essential to create inclusive growth for all.

Speaker: Andy Milne, Scotland’s Regeneration Network

Andy focused on community regeneration, arguing that the issue of centralisation and decentralisation is crucial. He stated that as a result of centralisation, urban areas – where most of the population live – are vastly under resourced.

Interestingly, he also noted that regeneration doesn’t work when not all areas are addressed. He argued that successful growth and inclusion will depend on economic policy decisions and not on all the small actions taken to address inequality.

Speaker: Richard Bellingham, University of Strathclyde

Richard’s focus was on smart cities. He noted that cities rely on critical systems – food production, waste/water handling, transportation, energy systems, health systems, social systems – and that if any one of them fails, the whole city fails.

The issue of rapid growth was emphasised as something cities need to respond to in a smart way. The recent 50-lane traffic jam experienced by Beijing suggests that there was a lack of smart thinking in its approach of building more roads for more people.

Richard suggested that greater collaboration is required for smart cities to succeed.

Speaker: David Allan, Scottish Community Development Centre & Community Health Exchange

The final presentation focused on community development. David highlighted the importance of community development approaches to build healthy and sustainable communities and referred to four building blocks of community empowerment:

  • Personal development
  • Positive action
  • Community organisation
  • Participation and involvement

Two examples of successful community-led initiatives were presented: Community Links (South Lanarkshire) and Getting better together (Shotts Healthy Living Centre).

Key elements of these initiatives were identified as: community-led, responsive to community need, fair and inclusive, and flexible and adaptive. Challenges were also identified: the level of understanding of ‘community’, community ‘stuff’ is often seen as nice but not essential and there is a lack of capacity and supply at the local level. David also noted that there is a danger that city-regions may exacerbate existing inequalities by concentrating resources in powerhouses.

He concluded by noting that future cities are unlikely to look like something from Back to the Future. Rather, they will probably look very much like today but the underlying systems need to change.

‘Smart successful cities – distinct, flexible and delightful (great places to be).’

An all-round approach: could the circular economy help the world turn the corner on climate change?

512px-Recycling_symbol.svg

This week, politicians from around the world are making a final attempt to craft a deal on climate change at the UN COP21 talks in Paris. The stakes could not be higher. Climate scientists largely agree that if the global surface temperature increase exceeds 2 ºC, the consequences could be catastrophic – drought, fires, coastal flooding, loss of agricultural production and increased spread of disease.

The role of the circular economy

Many believe one key element that could play a crucial role in curbing global warming is the transition from a linear to a circular economy.

Since the industrial revolution, the world’s economies have used a linear “take-make-consume-dispose” pattern of growth, a model which assumes that resources are abundant, available and cheaply disposable. But, in recent years, concerns about a combination of issues, including the depletion of raw materials and the amount of waste being sent to landfill sites, has increased interest in the concept of the circular economy.

The circular economy in focus

In our most recent “In focus” briefing, we take a look at the application of circular economy principles. The briefing outlines the development of the concept, which has moved from the fringes of the ecology movement in the 1970s to the mainstream of thinking on economic development today.

Circular economy principles have been adopted by companies such as Renault and by early-adopting governments in Japan and Scandinavia. Last week, the European Commission adopted a new Circular Economy Package aimed at boosting competitiveness, creating jobs and generating sustainable growth.

As well as highlighting the economic and environmental benefits of the circular economy, the briefing also describes barriers to further progress, such as product design promoting obsolescence and weak fiscal incentives for business.

The briefing also focuses on the role of UK local authorities in making the transition to a circular economy, and provides case studies highlighting examples of good practice.

Practising what they preach

As the international delegates in Paris try to deliver the first new global climate accord in 18 years, they might be inspired by their surroundings. The organisers of the conference have taken circular economy principles to heart, including the provision of locally sourced food, water fountains instead of plastic cups and the rental of furniture, structures, material and lighting for the event.

With the fate of the planet in the balance, it might not be too much of an exaggeration to describe the circular economy as a concept whose time has come.

The Aktivhaus: is this the future of sustainable living?

By James Carson

Earlier this year, we looked at a style of building known as Passivhaus, which is playing an important role in creating energy-efficient homes. Now, another concept – the Aktivhaus – is taking this approach even further, graduating from energy-saving to energy-generating homes.

The Aktivhaus concept

Like Passivhaus, the Aktivhaus has its origins in Germany. Stuttgart-based architect Werner Sobek defines Aktivhaus buildings as those which:

  • offset their annual total energy consumption in a sustainable manner;
  • anticipate and react accordingly to relevant changes both inside and outside the house;
  • continuously measure and optimise all energy streams.

Sobek’s idea has been realised in the form of a building called B10. This prototype Aktivhaus – prefabricated offsite and assembled in a single day – is located at the Weissenhof settlement in Stuttgart. It’s an appropriate site for applying a revolutionary concept – in 1927 the Weissenhof estate hosted a housing exhibition that included designs by leading lights in modern architecture, such as Le Corbusier and Ludwig Mies van der Rohe.

The Aktivhaus enacted

On the face of it, B10 is an 85 square-metre box with a full-length window. But its sophisticated design means the Aktivhaus can generate twice as much electric power from sustainable energy sources as it consumes. This means it can not only satisfy its own electricity needs, but can also power two electric cars and a neighbouring house built by Le Corbusier for the 1927 exhibition.

The ‘active’ element in the Aktivhaus is a mini computer, connected to the internet, that monitors weather forecasts and enables the house to respond accordingly, with different rooms heated or cooled at different times of the day. Other elements include a highly efficient heating system, web app-operated functions to control lighting and window blinds, and 17mm thick vacuum glazing whose three layers keep heat in and draughts out.

Werner Sobek believes that the Aktivhaus concept is not only applicable to new homes. “Our system is very helpful for old buildings,” he told the New York Times.

Some might feel it best to leave the imperfections as they are and not invest in major energy improvements and instead rely on the surplus energy from a ‘sister house,’ but the system can also help you decide to make modest changes to the windows or to improve the boiler.”

Over three years, researchers will study B10’s performance as a real-life residence. The building can later be dismantled and reassembled elsewhere, and when it reaches the end of its life almost all parts of the Aktivhaus have been designed to be recycled.

With construction costs of €100,000 and the technology inside priced at a further €600,000, the Aktivhaus is hardly an affordable housing option. But eventual scaling up of production could drive those costs down.

In the meantime, the ideas coming out of the Aktivhaus project may influence those looking for ways to tackle the ongoing issues of housing shortages, climate change and fuel poverty.
