Abstract:
Share of energy consumed in buildings in Serbia is 48% of total consumption, 65% of which is consumed in households. This paper investigates an energy efficient house which uses locally available Renewable Energy Sources (RES) for on-site electricity production and meeting thermal loads. In this paper a case study of a model of a house in Serbia is presented. The house model is grid connected, and it is assumed that it can send and receive electricity from the grid. The house is a part of a settlement, where houses are positioned for best solar energy utilization. The houses are equipped with both roof and wall mounted solar panels. This paper investigates the possibility of using a heat pump system and PV/t collectors for the production of electricity. Trnsys software is used to determine behavior of the modeled house throughout the year. Finally, an annual energy balance is made to show part of house energy demands which could be met using completely RES.
