n Journal of the South African Institution of Civil Engineering = Joernaal van die Suid-Afrikaanse Instituut van Siviele Ingenieurswese - Practical choice of thermal comfort scale and range in naturally ventilated buildings in South Africa : technical paper

  • ISSN : 1021-2019



The paper reviews human thermal comfort scales for naturally ventilated buildings. It compares the neutrality temperatures based on the new effective temperature (ET) with that based on the dry bulb (DB) temperature and provides the motivation why the DB base is preferable, given the relatively favourable South African climate conditions and the ease of calculation. It also investigates the most recent research developments in adaptive comfort neutrality temperatures and their ranges. These are applied to South African conditions to produce realistic and cost-effective target design temperatures for naturally ventilated buildings of two classes of stringency.
