Energy impact of an insulation #retrofit scheme in Kirklees, England

This article by Phil Webber, Andy Gouldson and Niall Kerr looks into the impact of a large insulation retrofit scheme in Kirklees. In UK cost-benefit analysis in the UK, the “engineering-calculation” impact of such schemes is reduced by 50% or more to take into account (a) defective installation and (b) “comfort taking” (residents choosing to have their house warmer after it has been insulated). The article shows that the scheme performed as well as this, in energy terms, among lower income households (presumably because they previously kept their houses colder than they’d like) – and better among middle and higher income households.

Public expenditure of £21 million (the scheme was free for households) led to savings of £6.2 million per year.
