Last week our Director Professor John Edwards was at the launch of the Climate Heritage network.  Speaking to an audience from around the globe at Edinburgh Castle Professor Edwards focused on the optimum approach to retrofitting traditional buildings and the guidance he has recently authored for the Institute for Historic Building Conservation. There were seventy-one founding members at the launch. The Edwards Hart team have contributed to numerous standards and guidance in the retrofitting of buildings and includes BSI PAS 2030 and PAS 2035. Training on retrofit delivered by Professor Edwards is delivered through the Environment Study Centre.
