Computer aided design (CAD) tools of various complexities are being used extensively to predict the energy performance of buildings. A simple user‐friendly CAD software was employed to estimate the cooling load profile of an energy efficient institutional building as a case study. At the same time, its air conditioning load pattern was measured and was found to be in good agreement with the predicted values. Parametric studies were carried out to assess the contribution of the various features incorporated in this energy efficient building. The results show that, by using such a simple tool, it is possible to identify the modifications which contribute to appreciable energy and demand reductions, and to gauge their economic viability. Such CAD tools are suitable not only for analysing new constructions at the design stage, but also for retrofitting of existing buildings.
