Non-residential buildings: input parameters for modeling the energy demand

L. Franke, K. M. Heissler, I. Nemeth

Abstract: This paper investigates the categorization of nonresidential buildings to calculate the heat energy demand of a large number of buildings in Germany. We applied a methodology for estimating the thermal envelope area of residential buildings, developed by the Institut für Wohnen und Umwelt (IWU, 2005) to a sample of 229 office buildings. Using this methodology we developed new parameters relevant to office building façade areas. We found that a consistent building depth is the decisive criterion for applying the method, leaving out building-types with heterogeneous geometries and user profiles. Regarding the study, resulting façade areas are slightly overestimated by an average 3 % with a standard deviation of 0.29.
