ABSTRACT
Usually buildings have several rooms; however, from modelling perspective, there may not be a requirement to model each room separately. In cases of multi-storied buildings, with typical floors, the model can be simplified by modelling only three floors: ground, mid and top. One of the important parameters that need to be considered while designing the building is aspect ratio, which is the ratio of the length to width of a building. The aspect ratio affects the envelope area. Increase in the envelope area leads to a higher heat gain/loss from the building. However, higher aspect ratio helps in better distribution of daylight and more access to windows for the occupants. This chapter explains the impact of these aspects on building performance through following four geometrical aspect tutorials: defining thermal zoning for a building, evaluating the effect of a zone multiplier, evaluating the impact of the aspect ratio and evaluating the impact of adjacency of the surface.
