Abstract:

The basic principles of creating environments for thermal comfort are well understood. This chapter presents those principles and uses them to address the new challenge of specifying conditions for sustainable thermal comfort. Currently accepted methods and Standards are presented which include the predicted mean vote (PMV) and the predicted percentage dissatisfied (PPD) thermal indices. A description of behavioural models leads to the equivalent clothing index (IEQUIV) and a suggestion that it is not necessary to heat offices above 20 °C nor cool them below 25 °C. If this practice were followed it would save significant resources and make a step change in ...
