The Meadows Area 3,800 homes 1,300 energy inefficient, 100 yr old solid wall (mostly privately owned) 2,500 energy efficient 1980’s (mostly social housing) Area of multiple deprivation High (32%) fuel poverty (10%+ household income spent on fuel) Since 1990 significant work already carried out on social housing (boilers/insulation)
Why The Meadows area
UK target- 60% CO2 reduction on 1990 by 2050
Building regulations and planning- all new housing to Zero Carbon by 2016
60% of current housing stock will still be here in 2050.
Mixture of new + old housing, social + private ownership
Greater appetite for energy/money saving measures
Need to support communities to adapt, especially low income.
Global/national issue reduced to a manageable scale.
Local social pressure and empowerment, identity + cohesion.
Lots of data needed
Range/distribution of property types
Range/distribution of tenancy types
Renewable resource potential in area
Renewables supply chain potential
Relevant National domestic funding streams
Energy assessment of typical property types
Suitable domestic carbon saving measures
Potential carbon savings from all applicable measures
Carbon savings already made since 1990
Total potential carbon savings and costs
Community consultation/involvement on options
Typical ‘Old Meadows’ House
Old Meadows-Typical 1900’s end terrace,
8.8 tonnes of CO2 per year
38,000kWh pa gas
3,488kWh pa electricity
65% efficient boiler
After modern boiler, grid green electricity, solid wall insulation, roof insulation, low-e lights.
3.8 tonnes CO2
19,500 kWh pa gas use.
Costing around € 11,500-13,000
Saving up to € 1000 pa
Typical ‘New Meadows’ house
Local authority owned
Already cavity filled walls
Already double glazed
Already well insulated
Boiler upgrades possible,
in process by LA
9,500kWh pa gas
1,800 kWh pa electricity
Very little left to do except District Heating or biomass boilers

The Area Renewables Potential
3,800 domestic rooftops, 900 with SW-SE facing roofs for PV, 1900 E-W for SWH. But low income area .
1 large wind turbine (330kW-150 homes)
Large PV array (70kWp-16 homes)
Switching to green electricity supplier
City District Heating possible (800m), expensive
Biomass district heating (small clusters)
River not suitable, very low head
Small wind not suitable, high density housing.
Individual biomass not suitable
Energy efficiency opportunities
Boiler and control upgrades covered by building regulations; people just repair though, don’t replace. Access to financing/grants as and when needed.
Solid wall insulation, expensive and disruptive, needs to be done as and when possible. Access to financing/grants.
Energy efficient appliances-affordable financing needed
Programmes to suit community
Turbine revenue to fund Community Energy Manager, who will work towards setting up a community energy company with energy industry partner.
Set up local Energy Learning Centre linked with community training and schools
Local refurbished (almost!) Zero Carbon exemplar house.
Later turbine subsidises a green electricity switch incentive fund.
Green loans programme 0%/low interest finance for renewables and energy efficiency measures. Interest rebated annually.
Local energy advisor/visitor
Realistically (without buying everyone SWH and dry lining) likely to be able to reduce footprint by around 44% on 1990
Intensive education maybe a little more
District heating could push this further, major investment.
Community biomass also with major investment.
Energy Learning Centre
Energy Pavilion +PV array
Tower to showcase renewable and sustainable energy technologies
Energy storage, water tower/hydrogen
Some revenue, ie trainer and energy manager
Seeking partners for IEE bid to establish a Sustainable Energy Community.
Fund local energy advisors/champions and volunteer programme.
With NEA + local community to develop a Community Energy Company to sell green electricity and manage loans for energy efficiency locally, with energy company partner.
