Development of a building energy model for carbon reduction in the UK non-domestic stock

The requirements for a scaleable energy model for the UK non-domestic building stock are described.. The non-domestic stock is much more heterogeneous than the domestic stock. The model needs to be scaleable from a single building, to a community or regional level. Approaches to using a small number of key inputs are described, using inference to combine empirical models, with building physics such as heat loss in a hybrid approach. Varying levels of information should be accommodated. Such models can be used to identify the most effective measures for reducing carbon emissions.
