Integrated Environmental Solutions-Visual Environment (IES-VE) is considered as one of the common thermal performance simulation programs. This study discusses the investigation on the accuracy of IES-VE Software in simulating indoor thermal environment of a double-story house in Bangi, Malaysia by comparing with on-field measurement. Air temperature, relative humidity and mean radiant temperature have been selected as the main variables to assess the thermal environment. The on-field measurements were carried out by using ΔΩHD323 WBGT-PMV (indoor measurement) and MK-III Weather Stations™ (outdoor measurement). The results reveal that the differences between the on-field and simulation measurements were in the acceptable range which is 10-20%. Therefore, the simulated data are valid and accurate for further thermal performance prognosis study for the tested building. The results in this study also agree well with those of other researchers. ER -
