  abstract: The goal of this research was to develop new techniques for designing and operating unconditioned buildings in a hot-humid climate that could contribute to an improvement of thermal performance and comfort condition. The recommendations proposed in this research will also be useful for facility managers on how to maintain unconditioned buildings in this climate. This study investigated two unconditioned Thai Buddhist temples located in the urban area of Bangkok, Thailand. One is a 100-year old, high-mass temple. The other is a 5-year old, lower-mass temple. The indoor measurements revealed that the thermal condition inside both temples exceed the ASHRE-recommended comfort zone. Surprisingly, the older temple maintained a more comfortable indoor condition due to its thermal inertia, shading, and earth contacts. A baseline thermal and airflow model of the old temple was established using a calibrated computer simulation method. To accomplish this, HEATX, A 3-D Computational Fluid Dynamics (CFD) code, was coupled with the DOE-2 thermal simulation program. HEATX was used to calculate the airflow rate and the surface convection coefficients for DOE-2, and DOE-2 was used to provide physical input variables to form the boundary conditions for HEATX. In this way, calibrated DOE-2/CFX simulation model was accomplished, and the baseline model was obtained. To investigate an improved design, four design option were studied: 1) a reflective of low-solar absorption roof; 2) R-30 ceiling insulation; 3) shading devices; and 4) attic ventilation. Each was operated using three modes of ventilation. The low-absorption roof and thte R-30 ceiling insulation options were found to be the most effective options, whereas the shading devices and attic ventilation were less effective options, regardless of which ventilation mode was applied. All design options performed much better when nighttime-only ventilation was used. Based on this analysis, two prototype temples were proposed (i.e., lo…
