Similarly for retail buildings, Centres (Base building)’, Centres (Tenancies)’ and ‘Shopping ‘Shopping Centres (Total)’ are each reported but may not be summed. An additional complication ‘Shopping – but also information set - is the above values include the energy use of supermarkets that are located in shopping centres, but a separate column estimates total energy consumption/emissions for all supermarkets (including those in shopping centres), and a final column estimates the energy consumption/ emissions of supermarkets, being those outside shopping centres. This ‘standalone’ approach was taken (as a value add, since supermarkets fall outside the terms of reference for the study) firstly because it was supported by the data, and secondly because the page revealed ‘Analysis’ significantly higher average energy intensities for supermarkets than for other retail buildings/tenancies. Note that since there is significant uncertainty about the share of shopping centres which is occupied by supermarkets, the model allows the user to change the default weighting for supermarket intensity within overall shopping centre energy intensity, both for whole buildings and tenancies. The default value is set to 22% (a BIS Shrapnel estimate) in both the Analysis’ and Tenancies ‘Retail – ‘Retail – Analysis’ pages, but the user may vary this. Note that any value above about 40% (supermarket share of shopping centres) would imply that ALL supermarkets were located in shopping centres. A note to this effect is included in relevant pages. These issues will be reported on further in the Final ‘Analysis’ Report of this study. Finally, the Figures’ pages by major building class are brought together into totals’ in ‘Summary ‘grand the Tables + Charts’ page immediately after the introductory page. This page ‘Summary ‘Overview’ provides the highest level national estimate of total energy and fuel use, and greenhouse gas emissions, from the non-residential building stock modelled.
