Abstract
Applicability of combined remedial methods for passive cooling depends much upon the most efficient interaction effect among them to provide occupants an optimal living thermal comfort. This research thus aims to utilize the small detached house in Bangkok as a case study to examine the best manipulation of architectural elements to provide an optimal thermal comfort in the Thai living context, and to propose a guideline for thermal comfort design. Information regarding microclimate of Bangkok Metropolis is retrieved from the meteorology office to be utilized as ambient input in the computer modelling. Several design factors - temperature, humidity, and air movement - are then tested to obtain the final model of comfort optimization strategy. Test result indicates that the best type of voids responding to the 90° wind direction is large openings with relatively smaller intake, which configuration is able to increase the interior wind speed up to 1.05 m/s. The optimal type of opening for diagonal wind direction, however, has been the medium size opening with zigzag interior void, which could obtain the interior wind velocity up to 1.5 m/s. The effective range of summer day-time temperature for passive cooling in Bangkok is limited to only 30 - 33°C.
