Information and analysis service

Location notice

Please note that this page contains information and links most relevant for people living in Scotland.

Increasingly, installation of energy efficiency measures in housing stock depends on identifying suitable households that can take measures and that are eligible for funding schemes, as well as understanding the cost benefits of different energy efficiency measures. 

Our expert analysts can help. We provide a free information and analysis service to help Scottish local authorities and housing associations identify the most cost-effective retrofit solutions for homes in your stock, enabling you to meet regulatory requirements (like EESSH2), reduce fuel poverty and help us all to reach net zero. 

Get in touch with us today to find out more about how we can help with your energy efficiency analysis and modelling – call 0131 378 6027 or email localhomesportal@est.org.uk.   

Intervention targeting

To support retrofit planning, Energy Saving Trust makes three key tools available: the Home Energy Efficiency Database (HEED), Home Analytics, and the Portfolio Energy Analysis Tool (PEAT).  

HEED is the key database of domestic energy efficiency measures installed under Scottish Government schemes since 1992. HEED provides important information on a range of property attributes and energy efficiency characteristics, which can support retrofit planning, such as:

  • Property type, tenure and age.
  • Wall type and insulation.
  • Loft insulation.
  • Glazing.
  • Main heating fuel type and heating system.

Academic researchers and community groups can also access this data (aggregated to the parliamentary constituency level for data protection purposes) to give insights on the energy efficiency of their region of interest.

Home Analytics is an address-level targeting tool that provides comprehensive information on all homes in Scotland. It includes over 90 fields of rich property information collated from:

  • The Energy Performance Certificate (EPC) Register for Scotland.
  • HEED.
  • Other relevant datasets, such as the Scottish House Condition survey and Index of Multiple Deprivation.
  • Datasets from other partners.
  • Multiple statistical and geospatial modelling techniques to predict the characteristics of every home in an area at the address level.

Home Analytics is designed to provide insights on the physical characteristics of a property, its energy efficiency potential, renewable energy potential, householder demographics, and funding eligibility (eg Energy Company Obligation (ECO)). It is also a key tool in supporting local authorities and housing associations develop and deliver policies to: 

  • Improve energy efficiency.
  • Promote low-carbon heating technologies.
  • Alleviate fuel poverty and target interventions (eg through EES:ABS).

Dataset analysis and modelling service

For detailed cost-benefit modelling, the Portfolio Energy Analysis Tool (PEAT) has been developed to use Home Analytics data, to help you target your retrofit planning more effectively.

The tool allows you to import housing stock data from your Home Analytics data extracts in batches of up to 500 addresses. These properties are then modelled using a Standard Assessment Procedure (SAP) based property modelling and improvements engine. You can use the tool to:

  • Determine recommended energy efficiency improvements and their costs for each property.
  • Conduct what-if scenarios to assess the impact of installing various measures on key metrics (eg EPC rating, fuel bills and energy consumption, carbon dioxide emissions and the risk of fuel poverty).
  • Calculate the likely ECO funding that may be available for each installed measure at both a property and stock level.

We not only offer free data analysis and modelling support, but we also provide training on the use and analysis of Home Analytics and PEAT, to empower users to build their team’s capacity to analyse and model this rich dataset in-house.

How to access support

Organisations wishing to discuss their energy efficiency analysis and modelling needs can call us on 0131 378 6027 or email localhomesportal@est.org.uk.
