Scottish Green Public Sector Estate Decarbonisation Scheme Progress Report

Projects Completed in March 2024/25

Project Title: Edinburgh Crown Office Retrofit (Phase One)

Project Organisation: Crown Office and Procurator Fiscal Service

Technology Type(s): Roof Insulation, Wall Insulation, Vacuum Glazing

Location(s): Edinburgh Crown Office

Checkpoint: 3

Grant Value: £2,250,000

Project Description:

The Crown Office and Procurator Fiscal Service is committed to reducing emissions from its buildings to reach net zero. The Edinburgh Crown Office was constructed between 1886 and 1888 and the long-term plan for the building is to complete a low carbon retrofit with the objective to significantly improve its thermal performance and install a clean heating system. The Scottish Government provided funding for the organisation to undertake insulation enhancement works including roof and wall insulation, and vacuum glazing. These measures will reduce heat-loss from the building by approximately 67% and are a pre-requisite for replacing the current polluting heating system with a clean heating system. It is predicted that this project will see annual energy consumption savings of 467,472kWh and annual savings of 85 tonnes of CO2 per annum.

Project Title: Edinburgh and Inverness Energy Efficiency and Renewables

Project Organisation: Scottish Courts and Tribunals Service

Technology Type(s): BEMS, LED Lighting, Electrical Metering System, Solar PV System, Secondary Window Glazing

Location(s): Edinburgh High Court, Inverness Justice Centre

Checkpoint: 5

Grant Value: £2,145,690

Project Description:

The Scottish Courts and Tribunals Service is committed to achieving net zero emissions and studied several buildings across its estate to investigate feasible methods of decarbonisation, including ways to improve thermal performance, air tightness, electric efficiency, and appropriate clean heating sources. The Scottish Government provided funding for the organisation to install a 40.89 kWp Solar PV System at the Inverness Justice Centre which is the last step required before heat decarbonisation at the site. The funding also supported secondary window glazing, lighting, metering, BEMS upgrades and installation of a 48.72 kWp Solar PV System at the Edinburgh High Court. These works represent the first phase in a strategic plan to enhance the building by reducing energy consumption, reliance on grid electricity and reducing heat demand to facilitate the installation of a clean heating system in the future. It is predicted that this project will see combined annual energy consumption savings of 312,556kWh and annual savings of 93 tonnes of CO2 per annum.

Project Title: Scottish Borders Multi-Site Renewables and Energy Efficiency

Checkpoint: 5

Grant Value: £2,256,000

Project Description:

NHS Lanarkshire is committed to reaching net zero emissions by 2040. Therefore, following on from pre-capital work previously supported through the scheme, the Scottish Government provided funding for the organisation to install roof insulation, draught proofing and Solar PV at its Kirklands Headquarters, in addition to a laundry WWHRS at the West of Scotland Laundry site. This funding also supported BEMS upgrades across more than fifty buildings on the estate. It is predicted that this project will see annual energy consumption savings of 2,242,402kWh and annual savings of 451 tonnes of CO2 per annum. This project was procured via the Scottish Public Sector NDEEF which forms part of GPSEDS.

Project Title: Tayside Multi-Site Retrofit

Project Organisation: NHS Tayside

Technology Type(s): ASHP, BEMS, Double Glazing, Draught Proofing, LED Lighting and Controls, Roof Insulation, Solar PV, Sub Meters

Location(s): Abbey Health Centre, St Margaret’s Hospital, Westgate Medical Centre

Checkpoint: 5

Grant Value: £3,276,344

Project Description:

NHS Tayside is committed to responsible energy use, environmental management and ensuring energy efficiency throughout its premises. The organisation commissioned a consultant to undertake detailed desktop appraisals and site energy audits to identify a suite of energy conservation measures that could be implemented across its estate. The Scottish Government provided subsequent capital grant funding for NHS Tayside to complete a low carbon retrofit of three primary care sites within the organisation’s estate. The energy efficiency, renewable and clean heating technologies installed include roof insulation, building energy management system controls, sub-meters, air source heat pumps, Solar PV, LED Lighting and lighting controls. It is predicted that this project will see annual energy consumption savings of 758,486kWh and annual savings of 134 tonnes of CO2 per annum. The project was procured via the Scottish Public Sector NDEEF which forms part of GPSEDS.

Project Title: Aberdeen Glazing Upgrades

Project Organisation: North East Scotland College

Technology Type(s): Double Glazing

Location(s): Aberdeen City Campus

Checkpoint: 2

Grant Value: £3,720,000

Project Description:

North East Scotland College has committed to half its total annual carbon footprint by the end of the financial year 2025 from the baseline year 2018-19. The Aberdeen City Campus Tower Block building was originally constructed in the 1970s and its thermal elements require upgrading to a modern standard. Single glazing in the South Block forms a large part of the external area of the building; however, offers little resistance to the flow of heat. The Scottish Government provided capital funding to support the installation of double glazing which will finalise all external windows works and future-proof the campus. This project builds on existing work undertaken by the college to fully reclad the site and is one of the first steps towards fully decarbonising the campus. It is predicted that this project will see annual energy consumption savings of 957,200kWh and annual savings of 176 tonnes of CO2 per annum.

Project Title: Police Housing Retrofit

Project Organisation: Police Scotland

Technology Type(s): ASHP, Double Glazing, Electric Heating Systems, Floor Insulation, LED Lighting, Pipework Upgrades, Storage Heaters, Ventilation Systems, Roof Insulation, Wall Insulation, Solar PV

Location(s): Forth Valley, Glencoe, Mull, Ullapool

Checkpoint: 4

Grant Value: £498,260

Project Description:

This project is part of a wider programme of works by Police Scotland to upgrade its domestic properties which are required for operational purposes to encourage police officers to work in remote and rural locations. The Scottish Government provided capital funding for Police Scotland to undertake various energy efficiency improvements to eight police houses across Forth Valley, Glencoe, Mull, and Ullapool. This included fabric improvements (replacement of windows, doors, and insulation), replacement of existing polluting heating and hot water systems, internal wiring, and pipework, in addition to installation of whole house ventilation systems, energy efficient lighting, clean heating systems, and Solar PV. It is predicted that this project will see a combined annual energy saving of 34,241kWh and annual savings of 16.5 tonnes of CO2 per annum.

Project Title: College Campus Low Carbon Retrofit (Building 3)

Project Organisation: West Lothian College

Technology Type(s): ASHP, BEMS, CWI, Double Glazing, Pipework Upgrades, Roof Insulation.

Location(s): College Campus, Livingston

Checkpoint: 5

Grant Value: £3,785,643

Project Description:

West Lothian College is made up of a single campus in Livingston, and the organisation is committed to reaching net zero by 2040. The college previously received grant funding to complete a low carbon retrofit of one of the buildings on its campus and sought to replicate this approach across other buildings on campus. The Scottish Government provided funding for the college to complete a low carbon retrofit of a second building which included double glazing replacement, cladding replacement, insulation improvements and installation of an ASHP. This funding also supported double glazing, cladding replacement and insulation improvements to finalise intervention in the initial building for which funding was received. This project is predicted to generate annual gas consumption savings of 323,984kWh and annual savings of 1,302.6 tonnes of CO2 per annum. It was procured via the Scottish Public Sector NDEEF which forms part of GPSEDS and annual savings of 42 tonnes of CO2 per annum.
