Abstract
In this paper I will describe the bringing together of sources of data on the nondomestic building stock and its energy use, and modelling procedures that form the technologically disaggregated model of energy use in UK buildings known as N-DEEM (nondomestic buildings energy and emissions model). Methodologies for estimating carbon emissions and carbon savings are described, and summary results presented. The use of N-DEEM to develop future scenarios of energy use is discussed.
