This is a note almost to myself but I thought I’d record it here as it took a little while to find the information earlier today. One of the spreadsheets we have setup at work is designed to help with analysing the energy usage, and hence carbon dioxide emissions, of a new development (specifically of a residential housing scheme). An accepted way of estimating such things is to perform a series of SAP calculations for each unit type (or at least a representative number of them). That produces an energy usage for such things as hot water production, heating, ventilation, etc. What is often required in addition, mainly due to planning guidance, is an estimate of the “unregulated” emissions (or energy use). This includes the energy used by appliances (fridges, washing machines and the like) and, subject of this post, cooking.
