Energiekonzept für Industrie-Großhallen: Technische und ökonomische Optimierung der Solarenergienutzung auf Basis einer Gebäudesimulation

Marina Stegelmeier, Martin Kaltschmitt

Abstract: This work analyses the possible savings in heating and cooling energy costs for factory buildings through passive solar energy use. As optimizing parameters window positioning and window area are chosen. Through building simulation in TRNSYS 17 the energy demand of a defined factory building in various constallations regarding window position and area is determined. The energy demand furthermore is supplied with different technologies for heat and cold generation and evaluated through the arising energy costs. As generation technologies condensing boilers, a heat pump and a compression cooling unit are chosen. Possible savings in single-digit percent range can be determinded. The heating demand clearly dominates the costs, since it is more than 20 times higher than the cooling demand. But overall, the costs are deteminded by the energy generation technology.
