13. Fuel running costs are modelled using a theoretical model (BREDEM) which estimates energy requirements from the characteristics of the dwelling, the heating system, fuel type, and external temperatures. Space heating requirements are based on 2 types of heating regimes - standard and enhanced. Households that include a person aged 75 or over or suffering a long term illness of disability are considered vulnerable and their running costs are based on an enhanced heating regime (23C in living rooms and 20C in other rooms for 16 hours each day). All other households are assessed based on the standard regime (living rooms heated to 21C and bedrooms to 18C for 9 hours on week days and 16 hours per day at weekends). No information about actual fuel running costs have been used. This is consistent with the new definition of fuel poverty in Scotland, following amendments agreed at Stage 2 of the Fuel Poverty (Targets, Definition and Strategy) Bill.
