Techno-Economic Evaluation of Energy Self-Sufficiency for the Energy Supply of Single and Multifamily Buildings
Abstract
Many consumers currently follow the idea of energy self-sufficiency and try to contribute to meet their energy needs to become independent and self-sufficient from the central energy network. In order to achieve load-related energy self-sufficiency, the energy supply must cover the energy demand at any time. Against this background, this paper analyzes the costs and potential of load-related energy self-sufficiency of single and multi-family buildings. It is differentiated between electricity-, heat- and energy self-sufficiency. The modelling is carried out with the simulation environment „Polysun Designer“ which allows a high temporal, dynamic simulation of the annual energy demand and energy supply.
