Abstract

Carrying out building energy simulations is a valuable part of a decision-making process which helps designers to evaluate various building design options and their impact on energy consumption. However, it is also time consuming. This became even more obvious when many models have to be created, either as a part of an iterative design process, or for studying energy requirements (and implementation of potential energy conservation measures) of a housing stock. Model simplifications can mitigate this issue. One of the simplifications is to remove internal partitions (zoning) and to treat a single floor as a single zone. In the domestic houses, single floor can be treated either as a lounge or as a bedroom since these are two dominant zones where occupants spend the most of their time. The impact of a model simplification on dwellings heating demand, operational carbon emission, overheating risk and collective overheating risk is analysed in this paper.
