Operative temperature and thermal sensation assessments in non-air-conditioned multi-storey hostels in Malaysia

This study assessed the influences of operative temperature on occupants’ perceptions of indoor thermal condition in three non-air-conditioned multi-storey hostels in Klang Valley, Malaysia. The thermal conditions of 24 measured rooms were recorded with and without an operating ceiling fan from May...
