Learning the lifestyle

Sustainable living has to be learnt. Even something as basic as putting out the recycling means understanding what can and cannot be recycled and which bin it must be placed in. When it comes to the home itself, things potentially become much more complicated. The most ‘eco’ home on the planet will fail to meet its full potential if the occupants don’t understand how it works; what’s more misconceptions are rife.

A recent blog by Dr Wolfgang Feist, of the Passive House Institute, set out to dispel myths about passive housing that even some in the industry have been guilt of perpetuating. Among the ideas he quashed was the belief that you can’t open windows in a passive house and that, due to mechanical ventilation, there’s a draft.

Worryingly there are also more practical issues to consider. The NHBC Foundation review, Indoor air quality in highly energy efficient homes, states: “Recent BRE discussions with UK manufacturers of MVHR (mechanical ventilation and heat recovery) systems suggest that there is no market for replacement filters with several reporting no filter sales at all. This suggests that maintenance is not being undertaken – even at the most basic level.”

Where technology such as MVHR is not maintained, there may be very real problems within the home such as a build up of humidity which, in turn, can lead to health issues and damage to the building’s fabric.

Maintenance in homes is already a big issue. If we’re lucky the gas boiler might receive an annual service but the need for more general maintenance has always been a difficult subject to get across. Many homes have failed due to even basic maintenance, like cleaning out gutters, being overlooked. When it comes to designing eco homes thought must be given to this aspect of human nature and it will be sensible to invest in proven technology which is simple and intuitive.

Consumer awareness, understanding and acceptance of ‘green’ technology in homes is undoubtedly in its infancy. This is partly due to the few examples of these technologies that have been installed to date. A survey by the NHBC Foundation – Zero Carbon: What does it mean to homeowners and housebuilders? – revealed that 92 per cent of respondents were found to have had no experience of micro-generation.

Meanwhile, Zero Carbon Homes: Creating the marketing programme, a report for the Zero Carbon Hub, highlighted the fact that 53 per cent of people have seen no ‘green’ technologies installed – even in a show home.

Education is undoubtedly the key but quite who should take responsibility for this is unclear. In the present climate it seems unlikely that it will be the government so the job will fall to housebuilders and, increasingly, to those involved in retrofitting the existing housing stock. Reaching the end user is not going to be easy but, unless a way is found, consumer ignorance and apathy could blight the road to zero carbon.

    It would make a very good start to get rid of confusing and wrong terms such as “zero carbon” or such stupid thesis like “wood” or “nuclear is carbon free” energy.
    Yes, the consumer takes the decision so she/he is the one to know and understand; e.g. the difference why draught proofing is just not good enough.
    By the way, why is it mainstream’s best guess that a government can not be expected to take responsibility e.g. for education? And why – if so – is it still called Government instead of … what?

  2. Good blog post Roger. Absolutely agree that there are risks from poor maintenance regimes – risks to our health and quality of life, risks to the fabric of our buildings, and risks to the UK’s aims of cutting carbon emissions.

    What seems to set things apart this time though is the latter set of risks. We have always had a situation where peoples’ neglect of their properties has resulted in damage and poor living conditions. This time around it matters more because the likelihood of problems are so much higher and because of the environmental impact too which could see many of our domestic low-carbon efforts come to naught.

    So you could argue that what we need is education about how to live more sustainable lifestyles as a whole, including understanding how a whole range of issues (shopping, motoring, travel and leisure etc.) impact on the environment.

    Interestingly though, I think starting with our homes would be an excellent place to begin. It could start at school (the new ‘home economics’ curriculum?), and would then extend to advice to students and tenants in rented accommodation (provided by councils, landlords and managing agents), to new home buyers (provided by housebuilders and warranty bodies), to anyone with buildings and contents insurance (provided by insurers), and to anyone undertaking home improvements (provided by product manufacturers, installers, RMI builders etc). As part of the home buying process, surveyors and solicitors could even check that proper maintenance regimes have been followed and documented, with all the relevant guarantees in place.

    This sort of awareness and rigour in making us good stewards of our housing stock may, I hope, take us a good way towards raising our overall environmental awareness and making us good stewards for the planet too.

SPAB Working Party

For the last 25 years conservation experts and volunteer heritage enthusiasts have come together to join the annual Working Party run by the Society for the Protection of Ancient Buildings (SPAB). I went along to join them and created a video about the Working Party at Sullington Manor Farm near Storrington, West Sussex. They were working…

Listed building allure

Every year, many of the estimated 450,000 listed buildings in the UK change hands on the property market. In England and Wales these properties are designated Grade I, Grade II* or Grade II having being deemed to be of historical, cultural or architectural interest. All buildings built before 1700

Environmental Pocketbook

Environmental Pocketbook

If you’re going to invest in just one book on sustainable, low carbon building I’d strongly suggest that you make it The Environmental Design Pocketbook. Now in its second edition, this useful volume by Sofie Pelsmakers should be essential reading for architects, designers, developers, planners, students, clients and anyone else involved in the construction and operation of buildings….

Fire in old buildings

Fire in old buildings

The devastating fire at the Grade I listed, 18th century National Trust mansion at Clandon Park, Surrey, once again highlights the need to do everything we can to protect old buildings. Whatever the size of the building, there are simple measures that can be taken to reduce the risk of fire, ensure early warning of a…

Adapting old buildings

Adapting old buildings

The need for fresh air and light in buildings is something I’m often talking and writing about because it’s central to creating a good home, but the theme is nothing new. I was reminded of this when I recently visited the King Edward VII Estate, near Midhurst, West Sussex. Here, the former sanatorium is being…

Building lime knowledge

Building lime knowledge

Lime, in the form of mortars, renders, plasters and paints, is a key component of old buildings and essential to their repair – or at least it should be. Today lime-based materials are also emerging into the mainstream and being used within low carbon construction systems, employed in everything from homes to superstores. All this…

Drain problems

A blocked drain is not a pleasant thing to wake up to. What’s worse is the realisation that it’s something that can generally be avoided by doing what I’m always talking about: maintenance. The drainage system is easily forgotten because much of it is hidden away underground but, as with any element of a building, it…

Materials testing

Materials testing

New techniques and materials aimed at producing low carbon solutions mean this is an exciting time to be involved with new build and retrofit. There are dangers though, in the rush to innovate there may be failures along the way so it’s vital that there’s scrupulously testing and monitoring at all stages. This is why…

Hidden London

Impending development often means there is a chance to step back in time because archaeological investigation may be undertaken as part of the work. This is especially true in London where layers of history have been laid down by successive generations as the city has evolved. Visiting Barratt London’s Landmark Place site close to the…
