Report on key findings from research: Affordable Eco-homes


I have written an initial report from the research project looking at ways we can make eco-housing more affordable. Please download a copy from here: Eco-homes Report 2011 (1 MB). Please also feel free to redistribute it.

You can also download higher resolution versions: Eco-homes Report 2011 (3 MB), Eco-homes Report 2011 (12 MB)

The key findings about low cost eco-homes are that:

~ We need both a technical assessment of materials and methods used, and a social assessment of people’s choices and decisions in order to understand eco-housing.

~ There is a diverse variety of eco-housing worldwide. The definition used in this report is that an eco-building minimises resource use (in construction and life-cycle) while also providing a comfortable environment in which to live. The USA has a long-standing and established eco-building culture, whereas eco-building has only existed in Thailand in the last decade.

~ We already have the technical knowhow, and many working examples, to build resilient eco-houses in Britain. However, ecological building methods remain marginalised and often misunderstood.

~ Eco-building will only be adopted if it offers what people demand from a house and that they can live how they want to within it.

~ The success of eco-housing is only as great as the behaviour of the people who live in it. Construction and technology cannot compensate for excessive energy use.

~ There remains a perception that building an eco-house is more costly, whereas figures for the lifecycle costs of buildings have proved that in the long term they are actually cheaper. More investment may be required upfront but it pays off in costing less to run throughout its lifetime.

~ Living sustainably has been associated with forgoing (doing without) many elements of contemporary life. However, a good eco-house is actually more comfortable.

~ It is not technology, or even politics, which is holding us back in building more eco-houses, it is deep rooted cultural and social conventions in how we live and what we expect houses to do for us.

~ Choices of building materials are made according to complex compromises between cost, local availability, skills and expertise required, suitability for climate, ecological properties, maintenance requirements and cultural attachments to certain forms. Thus eco-materials need to satisfy many criteria before they are adopted.

~ Eco-building involves more than technical changes to construction; it involves cultural shifts in how we consider our houses and homes.  There are dynamic relationships between physical structures and individual behavioural practices, culture, history and place.

~ There are many simple ways to make eco-housing more affordable, including:

  • Reducing the size
  • Simple design and avoiding the use of unnecessary technology
  • Designing affordability in at the start
  • Designing in modular units so that a building can be extended at a later stage
  • Internal open plan design to enable maximum flexibility
  • Using the space between buildings
  • Building collectively
  • Sharing common facilities and infrastructure
  • Sharing the cost of the land
  • Avoiding the use of experts
  • Participating in the debate about new planning regulations to ensure that eco-building is permissible
  • Careful choice of materials
  • Less durable houses
  • Using pre-fabricated elements or existing structures
  • Avoiding a purist approach
  • Ensuring design is aesthetically pleasing
  • Using hybrid combinations of materials

~ Planning favours buildings which conform to existing styles and norms and building regulations need to be negotiated.

~ Eco-building is gendered in that is it perceived to be a male domain where men are presumed to be better builders, more men than women actually build and women find their ideas and contributions to eco-building are often belittled. Socially constructed notions of gender have determined that strength is the most important attribute required for building, which is not true.

~ The replication of eco-build techniques worldwide has less to do with whether the build actually worked or its cost, but is influenced by the less quantifiable factors of foreign importation of ideas, the appeal of the aesthetics, open discussion of failure, a critical mass of support, assertive pioneers, and people understanding how their existing houses work.

~ Further research work is needed on how people understand their houses, how eco-build approaches are replicated, post-occupancy evaluations and the cultural dimensions of eco-building.

  1. Eco friendly projects in india is not a fashion,its a way of life & we are proud to be on of the leading Eco home builders in Bangalore.our Ecohouse is designed contextually for the users’ needs and lifestyle, making each home unique, relevant and tailored to your requirements.

  2. Thank you for all this information, for sharing it. Hopefully its the only concept that people select as an option. And hopefully I sometime make my own eco home.
    Thank you 🙂
