Refurbishing our tired & leaky old houses

A new post from Alison:

Yvonne and I went on a very interesting training course at the Building Research Establishment (BRE) the other day on Sustainable Refurbishment. It really made us think not just about the implications on the clients that we work with (particularly those that do refurbishment of social housing), but also about the refurbishment of our own houses.

We both live in houses that are at least 100 years old and as such they are pretty energy inefficient however tight we both are with the use of our heating! They are basically like sieves in terms of the heat and carbon emissions that leak from them! There were 3 main things that I took away with me from the course that we thought may be useful to share:

1. the Building Regulations apply to ALL properties undergoing refurbishment - the implications of this are potentially huge, although it became apparent that local authority building control teams do not always have the resources and understanding to police this. That is a real shame - the regulations are changing again next month and the requirements for energy efficiency (i.e. air tightness and use of A-rated equipment) are increasing - it is only through encouragement (e.g. grants and incentives) and policing that we can actually help implement the new requirements which will ultimately reduce real carbon emissions from the significant older housing stock we have in the UK

2. it costs money - refurbishing housing to meet Decent Homes standards costs money. Refurbishing them to Decent Homes standard + getting them to a point where they are energy efficient costs lots more.

3. but the technology is readily available to help improve the energy efficiency of older homes. What is missing are the skills and information to use and know about the new technology. Aerogel, external and internal insulation, photovoltaic panels, phase-changing materials....the list goes on. The new technology is really exciting. But we do not yet have a construction industry that has the knowledge and skills to implement it. This will of course change over time.

Maybe this is a classic case of demand and supply. Until the demand for new technologies is there on a large scale then the supply of them will remain expensive. It may be that the private sector moves quickly on this itself, or it may require Government intervention to help things happen more quickly. Either way it's exciting (if not challenging) times ahead.
