CLOTHING INSULATION AND THERMAL COMFORT IN AFRICA: CURRENT STANDARDS AND APPLICABILITY
Författare
Summary, in English
Methods: The research presented is based on a project aimed at the extension of the ASHRAE Standard 55 database to include non-western clothing. The paper focuses on the African clothing tested on thermal manikins. Three sets of female clothing and five sets of male clothing were measured. The ISO7730:2004 standard which uses the PMV/PPD indices was used to assess the optimal indoor temperature (assessed between 20-30 °C). The occupant was considered acclimatized with low activity (120 W), with an air velocity of 0.2 m/s, no additional heat radiation and a relative humidity of 50 %.
Results and Conclusion: The optimal indoor temperature for both women (PMV: -0.09, PPD: 5 %) and men (PMV: 0.1, PPD: 5 %) was found to be 24 °C. Considering better ventilation and evaporation in African clothing the comfort temperatures could be even higher. In conclusion, sub-optimal indoor thermal conditions are being adopted in Africa resulting in lower indoor air temperatures than required, causing an unnecessary waste of energy from AC systems and affecting the thermal comfort of the occupants.
