Study blames energy performance gap on modellers

Building modelling professionals are to blame for the difference between a building’s estimated energy consumption in design and how much it uses in operation, researchers claim.

Academics at the University of Bath’s architecture and engineering and psychology departments said it was vital to find the reasons behind this common performance gap, which resulted in non-domestic buildings using up to twice as much energy and emitting twice as much carbon dioxide as predicted.

The research focused on the building modelling stage of the design process and involved interviews with ...
