Primary data collection- non-residential construction
Data on the energy efficiency of non-residential buildings in Germany

This project will systematically and comprehensively record non-residential buildings. In a step-by-step process, data for modernisation such as the structure and condition of the buildings, their energy efficiency as well as influencing factors for decision-making processes will be surveyed.
