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).
