Description
Summary:The commitments to mitigate the negative impacts associated with final energy use stipulate the increase of energy efficiency of the built environment. This is the focus of urban energy policies and of built stock energy models that aid them. The complexities behind the phenomenon, however, hinder the development of the means for controlling and unbiased modelling. Such tasks necessitate the empirical evidence of causal relationships between architectural and technical attributes and building energy performance at the population level. This study, therefore, elaborates on the methods of inferential statistics for establishing such causal effects. The focus is on the methods of frequentist inference, active use of which may advance the understanding of the phenomenon and foster more accurate modelling practices. The case study examines the energy performance exhibited by distinct configurations of construction periods, envelope materials, sources of energy for space heating and the ventilation system types. The empirical sample consists of more than 11,000 records registered in the Norwegian energy performance certification system. The results document the effects and their significance. These methods are applicable in any urban context and may provide the empirical basis for promoting/discouraging certain technological and architectural tendencies, and simulating the phenomena through probabilistic programming.
