<p>Technological advances have assisted in the development of modern software tools which can be used to assess and improve the energy efficiency of a building at the early stage of conceptual design. However, this study aims at validating the accuracy of one of the paramount building simulation software Integrated Environmental Solutions - Virtual Environment (IES-VE), widely used today. The methodology of this study involves physical measurements and simulation exercises. A longitudinal physical measurement was carried out using HOBO ware U-12 in 5 different points of the room space from 18th October to 4th December 2016. But, for validation, a critical atmospheric day (21st November 2016) was selected for the comparison. The room air temperature was first measured before comparing it to the simulated air temperature obtained from IES<VE>. After several analyses, the comparison of the measured room air temperature and simulation results showed similarity, discrepancy, closeness, significance, and accuracy. The investigation findings revealed a percentage discrepancy of 11.03%, which is less than the threshold of 20% between the measured and simulated air temperature of the case study model. Other findings show that: R2 = 0.98, MBE = 0.8, °C and RMSE = 1.70°C are all within the acceptable values of significance between the two data. These results signify that IES-VE is valid, accurate, and applicable for this study's further Building Performance Simulation (BPS).</p>
