This paper deals with the impact of thermal insulation on indoor thermal conditions in a hot-and-humid climate (Malaysia). To explore this question empirically, two small masonry test cells were constructed, only one of which was thermally insulated. Both test cells were not occupied during the 10 day long test phase and only naturally ventilated. During daytime these openings remained closed, while they were opened in the nighttime for passive cooling. The test cells were equipped with data loggers for temperature and relative humidity. Parameters of the local outside climate were measured via a roof-mounted weather station. According to the experimental results, the insulated cell displayed a more stable temperature regime and
somewhat preferable thermal comfort circumstances. The disadvantage of night-time radiative cooling effect reduction was compensated by lower day-time temperatures due to insulation-based reduction of conductive heat transfer.
