Abstract

This paper investigates the role of the energy released by appliances and lighting on the heat balance of dwellings. This is studied in the context of building simulations, used for the prediction of temperature, energy demands and thermal comfort assessment of houses. For this study, 12 typical housing types, considered as representative of the entire Welsh Housing Stock, are used. The models’ input is based on generic housing data for Wales and recent “representative” European Domestic Electrical Consumption profiles. All the cases are compared against a reference model per dwelling, with no gains due to appliances and lighting. The annual energy demand required to maintain thermal comfort conditions for each model is calculated and the portion of it met solely by the energy output of the appliances and lighting is identified for all models. The results show the contribution from internal gains to the heating and cooling demands in the Case Study housing, the potential error range which exists in the predictions from using only average profiles, compared to real consumption patterns and the range of the demand profiles per house type, which is important for future studies regarding low energy and low carbon heating and cooling applications
