UK office buildings archetypal model as methodological approach in development of regression models for predicting building energy consumption from heating and cooling demands

An archetypal simulation model of office building representing variability in UK office building stock by parameterising built form, construction elements, occupancy/usage and operational/control strategy has been developed thus enabling detailed energy performance simulation to be used for stock modelling and parametric studies. The paper discusses the building characteristics needed to be considered for energy performance simulation, their values, and how they can be used in parametric studies. These parameters include built forms, fabrics (including thermal mass and insulation positioning), glazing percentages and characteristics, daylight and solar control measures and activity and operational related parameters (heating and cooling set points, ventilation rate, occupancy density and metabolic rate, equipment and lighting gain). The default parameter values suggested for the archetypal simulation model reflect typical existing and currently proposed UK office building stock. An archetypal model, combined with parametric studies, can be used in assessing energy performance of building stock and evaluating adaptation/retrofitting strategies.

► Archetypal simulation model representing variability in UK of office building stock is developed. ► Comprehensive literature survey on the parameters influencing buildings’ energy performance. ► Main parameters identified and their range and default values established. ► Using defined default values it is possible to create 3840 diverse yet typical office buildings. ► Developed approach enables energy performance simulation at stock level and parametric studies.
