All dwellings in the UK are required to have an Energy Performance Certificate (EPC) when sold or let, giving potential owners or tenants information on the cost and associated CO2 emissions of heat and power.
The Scottish traditional construction of solid stone walls tends to get unfavourable EPC ratings, leading to a perception that ‘old is cold’: this paper uses alternative calculation methods to question that perception.
The difference in results from steady-state and dynamic energy assessment methods is investigated for a dwelling with high thermal mass. The study focuses on modelled data and concludes that SAP 2009’s monthly assessment estimates lower energy use and therefore gives a more favourable EPC rating than the annually based RdSAP 2005; and further that the application of dynamic simulation models may not be the optimum solution to further understanding energy efficiency of this type of dwelling.
