Welcome to the UK summer edition of Passive House Plus! This issue of the magazine features a unique new passive house in Dundee that’s packed full of natural, low embodied carbon materials, and beautifully designed new passive-certified student accommodation in Cambridge, built with cross-laminated timber. There’s also two superb Irish projects: an amazing new curved timber passive house in Limerick, and the deep retrofit and transformation of a 1970s bungalow on the Sligo coast. This edition also has two special reports: one comparing the embodied carbon of six typical house build specifications, and another looking at the rise of CO2 monitors in preventing the spread of Covid-19. We also examine changes to RIBA’s 2030 Climate Challenge, ask what went wrong with the government’s Green Homes Grant, and cast a critical eye over whether 3D printing is really the future of housebuilding.
