The climate may change but our wish for a cosy home in winter, and a cool home in summer does not. Peter Warm, one of the leading Passivhaus consultants in the UK, talks about how the Passivhaus Planning Package (PHPP) can be used to design both summer and winter conditions, with a particular reference to retrofitting existing buildings, and the challenges that this brings. Delegates are assumed to have a basic understanding of insulation techniques, and the aim is that they will leave this workshop feeling wiser about which insulation and airtightness methods are low risk, and which high risk!
