Abstract: The different components of a building envelope such as covered area, windows and brick jalis, building materials, and shading devices regulate natural light, ventilation, and heat which impacts the occupants' visual and thermal comfort. The quality of light, ventilation, and heat gain depends on the amount of wall space provided for the windows which is expressed as the window-to-wall ratio (WWR), openings such as brick jalis, and shading elements. The design and utilisation of such components is mandated by architectural controls enforced by the local administration. This study focuses on the impact of these components of the building envelope on occupants' comfort and energy consumption. The study is based on occupant comfort, energy use, and thermal performance analyses of the two houses, situated on a V4 road in Chandigarh which is known for stricter architectural controls, which have been recently made flexible. Out of these two houses, the first house was constructed as per strict architectural controls proposed earlier by the Chandigarh administration and the other house was constructed as per flexible architectural controls introduced in 2008. The two houses have an identical orientation towards the southwest but differ in the permissible covered area, WWR, shading elements, and materials. Thermal comfort analysis, daylight analysis and energy consumption analysis will be done using tools such as Building information modelling (BIM) on Autodesk Revit 2022 and further simulation will be performed on on DesignBuilder 6.1.0.006 (EnergyPlus engine 8.9). The study intends to uncover the relationship between thermal and visual comfort and architectural controls.
