The Royal Commission on Environmental Pollution reported that the UK needs to achieve a 60% reduction in CO2 emissions by 2050 if we are to contribute to an avoidance of significant climate change. The domestic sector is crucial to the achievement of this target as it represents almost a third of the UK's energy. The 40% House project studies behavioural and technological changes in the search for how UK households can meet the 60% target. Through bottom-up analysis we aim to:
- Identify the policies required to achieve the 60% reduction in the domestic sector by 2050.
- Investigate the more careful use of energy, and the supply of energy through household-level new and renewable energies, including heat pumps, solar thermal and PV, and micro-combined heat and power.
- Determine the impact of expected climate change on the demand for heating and cooling, and identify the most appropriate ways of minimising this demand.
- Examine the load profiles of individual appliances and the extent to which these can be modified, with a consequent reduction in peak load.
- Assess the views of householders, so that proposals work with, and enhance, public opinion.
The 40% House conference took place on the 23rd March 2005.
Delegates attending the conference were asked to complete a questionnaire to ascertain whether they live in a 40% house.
