Project Title: Energy Efficient External Wall Insulation

Project Organisation: Calvay Housing Association

Technology Type(s): ASHP, EWI and CWI

Location(s): Barlanark, Glasgow City Council

Grant Value: £2,408,685

Completion Date: Projected June 2025

Project Headline: This project will deliver cavity wall insulation and external wall insulation to 36 blocks of flats, comprising of 267 properties

Project Description:

The properties recently had energy efficient windows installed. This project will install external wall insulation and cavity wall fill on 267 flats across 36 blocks. The blocks are cavity brick render, and most are currently heated with gas boilers. The insulation measures will increase the thermal efficiency of the buildings, help to lower tenants' energy bills, increase tenants' comfort, and reduce carbon emissions.

The project will also pilot an innovative ASHP to one property to allow for an evaluation of its performance in a real world setting relevant to Calvay Housing Association’s properties.

In order to measure the improvements, Calvay started monitoring properties in December 2023 and will continue monitoring during and for a 3-month period following the project completion. The ASHP will be monitored for at least 12 months following installation to evaluate the suitability of a wider roll out to all properties.
