Energy efficiency in the built environment

Professor Peter Guthrie discusses some of the barriers to improving energy efficiency measures in the built environment. He explains that a staggering 75% of existing buildings in the UK were built before 1975 and that the vast majority of these will still be in use in 2050. The technologies to retro-fit these buildings and improve their energy efficiency already exists. What is needed, he argues, is a real-time change of behaviour. Working with the property group Grosvenor on these issues, he explains how he hopes their new research with help influence built environment policies.
