Abstract: This paper aims to report results and lesson learned from students assignments in integrating thermal, energy, lighting, and acoustic performance in a building simulation project. The objectives are to observe the students approach in obtaining the baseline, target, and optimum performance in all mentioned aspects, and to analyse the differences between the submitted design proposals. The students were asked to simulate and predict the baseline and target values of thermal, energy, lighting (all using Sefaira) and acoustic (using CATT v9) aspects of a hypothetical classroom and to optimise the interior material properties. Based on the submitted reports, only 50% of the students modified the interior materials by considering the four aspects simultaneously. Among the aspects, lighting performance (sDA300/50%) is the most consistently predicted, with the coefficient of variance (CV) of 0.16 (baseline) and 0.07 (optimum). Meanwhile, thermal performance (annual overheating hours) is the least consistent, with CV of 1.28 (baseline) and 1.82 (optimum).
