Energy performance indicators of existing theatre buildings - classification of energy consumption and potential of energy-related refurbishment

In terms of climate goals, energy consumption of buildings has become a focus of attention. Energy consumption and energy saving potential of buildings differ depending on the building typology. The complex building typology of theatre buildings has not yet been subject of research, so no key energy values for the building stock were available. By means of a cross-sectional survey, a corresponding database was created. It was found that the average electricity consumption of theatre buildings is 60.5 kWh/(m(2)y). The specific consumption for heating and hot water is higher at 104.6 kWh/(m(2)y). The comparison with normative reference values has shown that the average electricity consumption value of the data collection exceeds these many times over, while the consumption value for heating and hot water is slightly lower. Individual factors that significantly influence the energy consumption level could not be clearly identified.
