  3. Parity information and analysis • Individual HomesHome Energy Masterplan • Housing stockCROHM

  4. Pay As You Save Trial - Sutton • Carried out the analysis for homeowners on behalf of B&Q working with Sutton Council • Interest free and 40% discount • ~ 100 homes assessed with 67 going onto have work carried out • Gave B&Q consulting advice on process and measures throughout – e.g. extra options, PV and windows

  5. The process • Survey arrangement (B&Q) • Data collection (Parity Projects) with B&Q/ROK person present • Client debrief (Parity Projects) – what we will evaluate/exclude • Data Analysis (Parity Projects) – offsite • Report delivery (Parity Projects)

  6. Home Energy Masterplan- what’s the difference • Advice not benchmarking • Occupational/behavioural inputs – actual use • Ability to calibrate • Recommend initiatives as: • Individual measures • Packages of measures • Present their benefit alongside their indicative cost • Technical – BREDEM based with bespoke modules for DHW, lights appliances etc. Also a large supporting database of materials, costs, products, appliances etc

  7. Home Energy Masterplan- what’s the difference

  8. What we learnt • Every home really is different

  9. Every home is different • a cliché but a major problem when financial advice is being given

  10. What we learnt • Every home really is different • Customers like having an independent advisor • 3 people bumbling around a house gets a bit crowded • Benchmarking tools (RdSAP and SAP) are not suitable for giving detailed recommendations and in particular financial advice • Getting everything done in one visit would be hard and probably not desirable

  11. What we learnt • Do not be fooled into thinking home assessments are trivial – under every stone... • Primary modelling: • Under heated and non-standard heated dwellings • Radical differences in DHW and electricity loads • Analysis: • Order of attack • Amending the base case – boilers • Pricing ...... • No-one wants their whole house renovated...front wall only... • Golden Rule [s] – myriad issues: prices, financing rates, sequencing, part subsidy

  12. Top Down – Stock Assessment Corporate Priorities Draft stock assessment Existing Housing Data Budget, Plans Maintenance Consultation, corporate priorities Data improvement and strategy Housing Retrofit plan Detailed Plans: Unit and/or Archetype level assessments

  13. Carbon AssessmentStage 1: data • EPC • CP12s • Street survey • Archetype analysis • Cloning

  14. Stage 2: Stock Assessment Total improvement possible (CO2 / year) £ / tCO2 / year More cost effective Greater total potential

  15. Stage 2: Stock Assessment CO2 Tenant FuelBills SAP

  16. Parity’s key takeaways • Don’t try and shortcut the assessment of a property – assessments based on averages or benchmarking tool just aren’t worth it • Housing providers should get their data in order and understand their strategy for their stock – it can be relatively inexpensive for the valuable guidance it provides • Chris Newman - 0208 874 6433
