Social housing: net zero progress report - quarter 2 2024

Project Title: Hawdene Zero-Emission Heating and Solar PV Energy Efficiency Project

Project Organisation: Eildon Housing Association

Technology Type(s): ASHP, Solar PV and Battery Storage

Location(s): Broughton, Scottish Borders Council

Grant Value: £521,021

Completion Date: March 2024

Project Headline: Project involved the installation of ASHP, solar PV and battery storage into 31 properties, primarily inhabited by elderly tenants experiencing fuel poverty

Project Description:

All 31 properties benefitted from the installation of these technologies which replaced inefficient electric storage heaters that were contributing to fuel poverty and poor carbon emissions. The tenants were primarily elderly in a rural area, experiencing fuel poverty.

The properties already had two types of insulation installed: cavity wall insulation and 270mm of loft insulation which helped to mitigate the transmission of heat through the walls of the property and through the roof. The ASHP and solar PV were effectively complimented by the battery storage to maximise fuel bill savings and provide an estimated 82% decrease in annual carbon emissions.

The project emphasised a tenant centered approach, incorporating an Affordable Warmth and Heat Impact Evaluation Assessment and intensive consumer engagement. Eildon HA will continue to monitor and actively respond to the specific needs and behaviours of the tenant’s heat usage, district heating effects and behavioural responses to tariff changes.
