Abstract

There is broad scientific consensus supporting the link between CO2 emissions and climate change. In cool and temperate climates such change is predicted to result in (among other impacts) warming ambient temperatures. As in recent years buildings in such locations have been increasingly optimised for heat retention (through regulations and standards), a warming climate has the potential to have a significant impact on the built environment and there is already evidence of overheating in new and recently constructed buildings.

Regulations in the built environment are largely designed to address issues of health and safety. In recent times however, such regulations have increasingly sought to incorporate issues related to energy efficiency while being used to implement national carbon reduction targets at the building scale. Arguably, building regulations remain focused on the ‘point of handover’ or near term performance, which given the uncertainty associated with predictions (such as climate change, occupant behaviour or technological change) is understandable. Such an approach however, in a situation where the current existing stock is seen as a major barrier to carbon reduction, risks buildings delivered today becoming prematurely obsolete due to the impacts of climate change.

Current overheating risk assessments in building regulations may not be appropriate as they are largely based on historic climate data. There remains a role however for regulations and standards that take account of the potential impacts of climate change. Building upon earlier research by the authors that demonstrates the potential magnitude of the overheating risk for UK dwellings, this paper suggests a risk based regulatory approach to overheating assessment based on climate change predictions while incorporating a requirement for adaptation planning. The approach put forward is based on semi-detached dwellings, built to new and emerging standards and regulations and aims to ensure that short term efficiency is not compromised for long term performance and comfort, thus minimising the potential for premature obsolescence related to overheating.
