Project Title: Longstone Primary School Energy Efficiency and Renewables

Project Organisation: City of Edinburgh Council

Technology Type(s): Roof Insulation, Cavity Wall Insulation, Double Glazing, Solar PV

Location(s): Longstone Primary School, Edinburgh

Phase: 1

Grant Value: £339,255

Project Description:

This project involves energy efficiency upgrades and the installation of renewable technologies at Longstone Primary School in Edinburgh. It is a pathfinder project for City of Edinburgh Council which integrates the principles of deep retrofit with condition-based improvements and the outcome of this project will help inform future asset management works in the Council. The Scottish Government provided capital grant funding via Salix Finance to enable a significant reduction in the building’s carbon emissions. This will be achieved through fabric first upgrades including roof insulation, cavity wall insulation and double glazing, as well as the installation of Solar PV. The measures installed are a pre-requisite for conversion to a clean heating system in order to achieve full heat decarbonisation at the site in the future. It is predicted this project will see annual energy consumption savings of 156,896kWh.
