My office in Cambridge UK faces south, so I designed and am sharing the design for this simple demountable awning that can be put up quickly and easily to stop the sun streaming in. This keeps it cool on hot days. I find the shade this provides allowed my office to be at a comfortable temperature, even during the record breaking heatwave of 38.7C in July 2019. The awning can be removed and stored easily when not needed.
As climate change gathers pace and heat waves become more common, energy efficient ways of keeping cool in summer become more important.
