In terms of illumination levels and health advantages, using natural sunshine in the building saves energy. In the hot and dry climatic zone, however, an increase in daylight availability could lead to heat infiltration. This could lead to an excessive amount of energy conservation. The goal of this study is to provide a methodology that can be utilised as a pre-design tool for evaluating lighting and thermal performance of areas within buildings that designers may use during the design process. The field measurements were taken on the liveable spaces of a Nagpur-area housing unit. Both illumination and thermal energy simulations were carried out using Ecotect Analysis 2011. The results of the field measurements were compared to those of the simulation. Because the percentage difference (PD) between Ecotect measurements (EM) and field measurements (FM) for both thermal loads and illuminance levels was less than 15%, the simulated model was deemed accurate enough for future investigation. The findings suggest that the simulated model would be sufficient for designers to analyse parameters such as wall to window ratio and shading devices in relation to the building's orientation in order to attain the best possible useable daylight index.
