NEXT STEPS There are many reasons to target the deep retrofit of buildings from human comfort to carbon savings to fuel poverty and associated health benefits but there are also significant practical challenges which need to be addressed. Indeed, given the scale of the challenge and its global importance and the need for a coordinated plan it could be considered as a national infrastructure project (as per the Scottish Energy Efficiency Programme). However, this is not a plan that can be imposed on existing buildings because it involves millions of separate projects and building owners. As shown deep retrofit to the EnerPHit standard can deliver huge improvements in thermal comfort to building users whilst offering significant energy and carbon savings and is cost effective in the long term. 26 |
