Concept and First Energy-Balance Results of an Energy- Autonomous House
Abstract
One new concept for single-family buildings is the Energy-Autonomous House which is presented in this study. The concept is an advancement of solar houses and efficiency houses with fully self-sufficiency in electrical (100 %) and thermal energy. Therefore a reduction of the energy consumption (electrical and thermal) by increase of building efficiency is necessary. The house includes utilization of solar energy with photovoltaic panels and solar thermal collectors coupled with storages (battery, electro mobil and thermal storage tank). Further a water cooled fireplace is integrated for the supply of thermal heat during winter month. To proof the self-sufficiency under realistic user behavior two occupied houses are built in Freiberg / Germany and which are now under an extensive monitoring. First energy-balance results show good correlations among planned and measured consumptions for Jan. - July 2014.
