Simplified building model of districts

In the setting of this paper, a building is represented by a simple model consisting of two thermal masses. Generic values were obtained for two unknown parameters in the model, capable of representing an office building, a single family dwelling and a multifamily dwelling, at three levels of thermal insulation. The model allows the aggregation of multiple dwellings into a single aggregated building. The dynamic thermal behaviour of the aggregated building closely resembles that of the sum of individual dwellings. As a result, dwellings within a residential district can be modelled with a limited amount of information, allowing a quick assessment of their dynamic heating and cooling demands.
