When houses are retrofitted with cavity wall and loft insulation, the actual energy savings derived from measurements of before and after fuel consumptions are commonly found to be considerably less than expected from model predictions. This discrepancy, termed a ‘reduction factor’ is caused in part by changed internal temperatures, a ‘comfort factor’, with the remainder due to other causes, such as insulation performance, occupancy and ventilation.
