Development of Reference Buildings to Analyze the Potential for Energy-Efficient Refurbishment of Buildings

Abstract

The building sector offers the largest potential for a significant reduction of greenhouse gas emissions. Based on own preliminary investigations for the State of Bavaria, a complete renovation of the building envelope of the current residential building stock would result in a reduced demand for final thermal energy for space heating and domestic hot water by about 70 %. The present study analyzes different existing reference buildings and reference methods. Based on a general literature review, specific criteria will be developed for reference models to represent the thermal energy consumption of the residential building stock for the regional domain under investigation. The objective is to represent the building stock with a limited amount of reference buildings. The method for the development of a reference building will be shown exemplarily for one category.

Development of a realistic scenario for the thermal energy demand of residential buildings in Bavaria till 2050

“…Detailed results and analysis on the composition of the Bavarian building stock and its energy demand for space heating and domestic hot water preparation have already been published [25,26]. Examples for the use of these data for further analysis supported by appropriate reference building models have been presented in [27,28].…”
