Nottingham Community Housing Association works with NetZero Collective on project to decarbonise more than 200 homes for older people

Seven assisted living schemes for older people, totalling 214 homes, were assessed under PAS2038 guidelines and outline plans were created on how they can be successfully decarbonised.
NetZero Collective undertook retrofit assessments, pre-retrofit coordination, 3D scans to create digital twins of each block, drone surveys, architectural/CAD drawings, topographical surveys, and communal heating condition surveys.
Following the analysis of the buildings owned by Nottingham Community Housing Association, NetZero Collective put together a scheme report to decide how best to minimise energy demand by improving the fabric of the property first, before switching to a low or zero-carbon energy source.
Some key recommendations included improved loft insulation, new external wall insulation and cavity insulation to minimise energy demand. Other recommendations included a mixture of zero-carbon technologies, including air source heat pumps, solar photovoltaics and battery storage.
The retrofit works proposed by the experts at NetZero Collective are projected to eliminate an average 49% of the carbon emissions per home, which equates to the elimination of 18.5 tonnes of CO2 by 2050.
