  • Abstract:
    The task of achieving major CO2 reductions in the residential building stock raises a wide range of policy issues, from the relationship between the rate of demolition and preserving 'heritage' areas, the standards of new build, embodied energy, roof orientation, and the provision of on-site generation. These are all vital, but the paramount task is the refurbishment of the existing building stock. In the UK, 87% of existing homes are expected to be standing in 2050, with a space-heating demand that has been reduced from 14 600 to 9000 kWh per year through the provision of high levels of insulation and measures to avoid the need for air-conditioning. For all homes, old and new, major carbon reductions will require the installation of low- and zero-carbon technologies and reduced energy consumption in appliances. The scale and urgency of the task is identified, with some pointers, to progress the policy debate. The research is based on the 40% House (2005) report and uses Oxford's UK Domestic Carbon Model. Whilst most of the evidence comes from UK households, the lessons have wider ramifications, both for other sectors and for other countries. Behavioural change will be a vital component, whether from the different professions and trades involved, or from the occupants.
