Energy Efficiency and the Real Estate Economy

The project examines to what extent energy-saving building methods and / or energy efficiency of buildings are expressed in their market values. Because of lower energy consumption and the associated lower running costs more energy efficient real estate is expected to be preferred by consumers / users and will therefore obtain higher values than less energy-efficient buildings. These higher market prices represent an important market incentive for investment in more energy efficient building methods and utilities. Valuation is an important instrument for the real estate economy. Therefore, first the question is examined whether energy efficiency plays a role in valuation appraisals (and if yes, which). First national and international standards will be examined. Then valuation appraisals, which were used in real estate practice, will be analyzed by means of a content analysis and if necessary a meta analysis. Experts might mention energy efficiency in their appraisals and in the form of anticipated payments consider it in addition to the prescribed elements of the evaluation.
