N2 - This paper investigates the thermal performance of four school buildings of different ages and characteristics, using current EU overheating criteria and ‘adjusted’ criteria based on children’s lower comfort temperature found in recent research. Data collected in Southampton, UK, between 2011-2015 are used in the analysis, which consists of two parts: a) the development of an adaptive comfort model associating children’s comfort temperature to outdoor climate based on approximately 2,800 thermal comfort responses from children, and b) the thermal performance evaluation of four case study schools (built in 1894, 1929, 1978 and 2013) with the use of 5-minute air temperature measurements during spring/summer from a total of 43 classrooms. The two models, current (adult-based) and adapted to pupils, are applied to the methodology for overheating assessment based on the European standard EN 15251.
