Summary

This paper describes the practical application of an Adaptive Thermal Comfort Policy for school buildings in Australia. To date decisions about where and when to install air-conditioning in schools have been based on an isotherm on the climate map of the region in which they operate. The ASHRAE 55-2010R adaptive model was used as the basis for the thermal comfort criteria with an exponentially weighted running mean outdoor temperature for input. Two metrics have been proposed for the diagnosis of overheating: a) % of occupied hours during which indoor operative temperature exceeds the upper limit (80% acceptability), and b) cumulated degree-hours based on an indoor operative temperature baseline of the upper limit (80% acceptability). Indoor microclimatic data was collected from these schools with simultaneous application of thermal comfort questionnaires. Data from these field studies reinforces the adoption of the Adaptive Thermal Comfort Policy, stimulating naturally ventilated buildings, increasing adaptive opportunities and behavior within these indoor environments before resorting to air- conditioning as the main provider of thermal comfort.
