Abstract: 26 million homes¹ (Killip G., 2008) in the UK are traditional and ‘hard-to-treat’² dwellings that need urgent attention in order to meet the government’s carbon reduction targets. Most of these homes are situated in villages without mains gas. A computational methodology will be used to formulate energy retrofit and renewable energy technology (RET) solutions for a Welsh village. The UK Government’s widely used tool, Standard Assessment Procedure (SAP), is used for modelling baseline energy consumptions and energy efficiency measures for the dwellings. Due to shortfalls in SAP, the small power demand will be assessed in EnergyPlus in order to design power generating RETs. Furthermore, RETs such as solar photovoltaic (PV) and wind turbines will be modelled using software packages PV*Sol and RetScreen respectively. The assessment highlights the limitations of the chosen computational simulation methods by formulating various feasible alternative energy solutions for the village.
