Solar energy impact on space heating and cooling needs in moderate climate
AbstractThe paper describes impact of solar energy on a standard new building of a low energy consumption for space heating, and shows a problem of overheating of such a building in summer, that occurs quite often nowadays in moderate climate. The paper presents how important is to analyse in details the solar energy availability for a building envelope, especially for glazing of different orientation and inclination. Impact of solar energy on the energy balance of a building is analysed. Results of numerical simulations of dynamics of a building and its surrounding are presented. The focus is put on monthly changes of the space heating and cooling energy needs for every month of the averaged year – with regard to the solar energy influence depending on the different orientation of the rooms of a building. It turns out that cooling demand previously very small, now can become very significant and can dominate the total energy demand of new buildings, especially for some location of rooms and apartments. The results of simulation studies presented in the paper indicate necessity of changes in existing regulations on determination of energy performance of buildings, especially for certification of thermal energy performance of residential buildings.
