Energy Efficient Scotland Phase 2 pilots: final social evaluation report

1. Introduction

The Phase 2 pilots, coordinated by Scottish Government, took place between September 2017 and March 2019. The pilots form a part of the development of broader Energy Efficient Scotland programme, following from the Phase 1 pilots, which have been evaluated separately^[1]. The Phase 2 pilots included nine local authorities (see Table 1 and Figure 1) and sought to support further capacity building within local authorities, with a focus on^[2]:

• The building blocks of programme delivery – testing the entire process and individual components of delivering heat and energy efficiency projects
• Heat decarbonisation – provision of all forms of low carbon heat, with focus on area-based schemes; district heating
• Hard-to-treat buildings – including historical buildings and conservation areas
• Sector specific projects – projects which seek to engage with, for example, only the commercial sector, private sector landlords, or owner occupiers ‘self-funding’ works.

Table 1: Description of the activities carried out for each of the Phase 2 pilots.

Local Authority: Aberdeenshire

Non-domestic

Project details - The proposed project included Loft Insulation, SWI, Under floor insulation, Solar PV battery storage, LED sensor lighting and a heating system upgrade for a sports and community trust

Local Authority: Argyll & Bute

Domestic & Non-domestic

Project details - Transforms building energy efficiency throughout the conservation area of an Island community, which includes much of the visitor accommodation, and a critical mass of businesses and public and community buildings, including school, surgery, library and very heavily used Village Hall

Local Authority: East Ayrshire

Non-domestic

Project details - A Community Hall will receive External Wall Insulation, window replacements, LED lighting and, once insulated, an ASHP heating system

Domestic

Project details - Energy efficiency improvements to 4 properties yet to be treated in an area previously improved through EESSH.

Local Authority: Edinburgh

Non-domestic

Project details - A number of public buildings, including museums and a bus station have received the implementation of demand based control of plant and equipment, reducing and shifting load from peak periods and the application of Building Energy Management System analytics to determine and optimise performance of controls

Domestic & Non-domestic

Project details - Energy retrofit and improvement works on a Category B listed building, to test approaches to energy efficiency in hard to treat, post war properties. This included one block of 12 flats and 2 commercial units.  

Non-domestic

Project details - An integrated programme of activity delivering energy efficiency improvements and a renewable heat supply within a listed, hard to treat property, for use by local community groups. The energy efficiency measures and renewable heat technology include the installation of an air source heat pump system combined with an LED lighting roll out, roof insulation and an innovative building energy management system 

Non-domestic

Project details - The new buildings on a redeveloped council-owned park and the existing winter gardens will have an integrated renewable energy solution for their heat, through the installation of ground and air source heat pumps.

Local Authority: Falkirk

Domestic

Project details - Extending the existing Local Authority-owned District Heating Network to 260 new properties predominantly occupied by over 50’s in fuel poverty. Replacing a mixture of existing gas and electric heating with spare heat capacity from the existing Combined Heat & Power, and utilising available electricity generation to supply nearby electrically heated primary school – achieving a B Energy Performance Rating across the Estate.

Non-domestic

Project details - Lighting improvements and connecting a private wire to supply CHP electricity, in 3 schools and a council office.

Local Authority: Glasgow

Non-domestic

Project details - The principle objective of this project is to improve the energy performance of 400 (small to medium) commercial business units across Glasgow. This work will reduce energy consumption, carbon emissions and operating costs for small to medium sized enterprises. The businesses vary in type from newsagents, hair salons, public houses, etc

Domestic

Project details - Trial the installation of Building Management System controls and also Solar PV in a Social Landlord’s head office in the centre of Glasgow City.  The aim is that the building’s energy plant and equipment ostensibly become ‘smart enabled’ appliances that can be controlled based on actual building demand rather than pre-set parameters. In addition, the installation of a 50KW Solar Photovoltaic array will generate energy that will be matched with the BMS systems to maximise the locally produce renewable component of energy demand within the property.

Non-domestic

Project details - To reduce energy demand and promote decarbonisation within two locally run community centres by investing in the introduction of building fabric energy efficiency upgrades and installation of renewable energy technologies as well as implementing long-term behavioural change.

Non-domestic

Project details - To develop and implement an innovative and systematic controls strategy to up to four Glasgow Life premises. This project spans 3 leisure Centres and Swimming Pools

Local Authority: Orkney

Non-domestic

Project details - The Council has an energy efficiency programme as part of its five-year cyclical maintenance programme to improve the energy efficiency of its non-domestic building stock. This Energy Efficient Scotland project aims to improve the efficiency of a school building with external wall insulation, roof insulation and others.

Local Authority: Scottish Borders

Domestic

Project details - Development of community hub to engage and support local residents in energy efficient retrofitting interventions.

Non-domestic

Project details - Non-Domestic Energy Efficiency Measures in a local High School

Local Authority: South Ayrshire

Non-domestic

Project details - Improve the energy efficiency of Ayr High Street which is currently at the focal point of regeneration plans; this will be done through a combination of measures, low carbon technologies and education. 

Domestic

Project details - The objective is to improve the energy efficiency of households in rural South Ayrshire with high fuel bills that are not considered to be in fuel poor areas. Targeted properties would be EPC band E, F or G
