Assessing residential retrofit measures to reduce the risk of fuel poverty: A modelling approach at community scale

Paraskevi Vatougiou, David Jenkins, Peter McCallum

Abstract: This work focuses on a modelling-led approach regarding the impact of different retrofit measures on limiting the risk of fuel poverty within a grid-constrained community. 102 house archetypes are selected to represent 322 existing dwellings located in Orkney, Scotland. Archetyping is based on a parametric housing stock energy model using GIS (Geographic Information System) data and EPC (Energy Performance Certificate) datasets (or equivalent) to automatically generate house models suitable to be studied using the EnergyPlus dynamic simulation engine. The sensitivity of each house archetype to fuel poverty risk is evaluated for different household’s income bands. When all houses are assumed to belong to the lower income band, the application of a full fabric retrofit package results in limiting fuel poverty risk from 46.1% to 21.6% within the modelled community. Only 4.2% of the houses still remain vulnerable to fuel poverty when a full fabric plus heating system retrofit package is applied.
