Analyzing the Energy-saving Potential of Buildings for Sustainable Refurbishment

For the sustainable redevelopment of existing properties,it is important thatthe measures taken pay off economically as well. With the energy-scoring method presented in this paper, portfolios can be classified according to their energy-saving potential. Besides the various factors affecting the reduction of primary energy demand, the 3-tier model analyzes and correlates the economic efficiency. The result is an objective ranking of each object, from which property owners can deduce where they should ideally invest in order to optimize the energy efficiency of their building stock sustainably.
