  • Energy Use and Generation: Modelling and Mapping for Social Housing Landlords 
    Antony Scott, GECO/STEEV 'Green Energy Tech' Workshop, ECCC
    13th October 2011
  • Background
    ....provides carbon reduction services to Housing Associations
    .27 million homes in Scotland
    2.5 million homes in England
    Affordable rented housing
    Not for profit
    Government support and regulation
  • The question...
    How can GIS help social landlords to improve energy management?
    Feasibility and Implementation
    Auditing and Planning
  • Auditing and Planning framework
    Where are we now?
    Where are we going?
    {
    How will we get there?
    Where do we want to go?
  • Process Steps
    Map
  • The maps
    Map controls
    Postcode averages
    Layer chooser
    Management ‘patch’ averages

  • Key questions: strategic
  • Feasibility and Implementation: Solar PV
  • The Economics
    Pre-PV
    • 4,500kWh bought at 11p/kWh
    = £495 cost
    Post-PV
    • 1,000 kWh generated, FiT at 43.3p/kWh = £433 income
    • 500 kWh exported @ 3p/kWh
    = £15 income
    • 4,000 kWh bought at 11p/kWh
    = £440 cost
    Annual gross cost before: £495
    Annual gross cost after: £-8
    Capital cost: £6,000
    Generation
    43.3p/kWh
    Export 3p/kWh
    Avoided Purchase 11p/kWh
  • Where to start?
    Which roofs are suitable?
    How much can we earn?
    What about shading?
    How much will it cost?
    How much will our tenants benefit?
    What will be the impact on carbon emissions?
    How can we fund it?
    In other words:
    What’s the business case?
  • Process
  • Stereo pairs
    shapefile
    Digitised roofs
  • Solar Irradiance
    Generation capacity
    Roof attributes
    Data schema
    Income
    Etc...
    Panel spec.
  • Roof detail data
    Business case data
