Cri presentation 23.11.11 Cri presentation 23.11.11 Presentation Transcript

  • Bruce Pittingale Executive Director The Carbon Reduction Initiative (CRI) East CIC www.insulationorenergy.org [email_address] 07545 769 645 Taking Action to reduce Fuel Poverty
  • The energy efficiency driver
    • My colleagues today have outlined
      • The effects of fuel poverty
      • The negative medical effects of fuel poverty
      • Energy conservation
      • Community role in developing a vibrant community
    • I wish to discuss with you what actions we can take.
    • The difference between energy conservation and energy efficiency.
    Energy Conservation
  • Energy Efficiency
    • What physical barriers we can use to save existing heat
      • Loft Insulation
      • Cavity wall insulation
      • Draught proofing
      • Solid wall insulation
      • Double/ triple glazed windows
      • Removing dampness from the home
      • Using low energy bulbs and lights
  • Loft Insulation
    • Survey shows 80% of homes not insulated to today’s standards
    • 270mm (10”) deep
    • Ensure eaves clear
    • Wires lifted
    • Tanks and pipes cocooned
  • Cavity Wall Insulation
    • 35% of heat escapes through this area
    • Homes built after 1935 have cavity walls
    • Not all homes are insulated when built even today!
    • Making homes into a thermos flask
    • 25 year guarantee from the Cavity Guarantee Association (CGA)
    • Myths around cavity wall insulation
  • The cavity is inspected for suitability A survey is undertaken and your home assessed Arrangements are made for the installation team to install your cavity wall insulation. Holes are drilled in a pre set pattern in all external walls A test box is filled to ensure the correct density of material is used The material is delivered by the machine in the back of the van To the wall by hose…. and the cavity completely filled Finally the holes are filled to match the existing fascia
  • Draught proofing and Double glazing
    • Around 10% of heat is lost through the windows of a single glazed property
    • Around 15% is lost through gaps around doors and windows
    • Another area is around the loft hatch which should also be draught proofed
    • Enough ventilation should be left to serve any appliance that draws air from the room
  • Solid wall insulation
    • A more expensive remedy for old housing, built before 1935
    • Can be insulated from inside or outside
    • Will change the façade of the building when insulated from outside
    • Services and door/ window reveals need to be extended
    • All pipes and rainwater need to be replaced
    • Electricity and telephone wires need to removed and then refixed
  • Damp air……
    • Is heavier to heat
    • Can be the result of condensation, rising dampness in walls or water penetration
    • Replace bathroom and kitchen extractor fans and replace with heat recovery units
    • Ensure there is at least one change of air per hour (rule of thumb) through the property
  • The Carbon Emission Reduction Target
    • Finishes in 2012
    • Grant aid provided by energy companies
    • Supports
      • Loft Insulation, top up as well as full insulation
      • Cavity wall insulation
      • Some companies support solid wall insulation
  • The Carbon Emission Reduction Target
    • Qualifying criteria
    • Any home in the owner occupier and private rented sector
    • Rented properties need written approval of landlord
    • Approximately £149 for loft or cavity wall insulation
    • Normal price for 3 bed semi house £550 - £600
  • The Carbon Emission Reduction Target
    • 100% grants for the following people
      • Any person over 70
      • Those with a disability of any age
      • Low income families
      • Low income single persons
    • CRI East also checks for local grants from Councils as part of its service.
    • If there is a grant which is more cost effective than the CRI offer we promote the better offer
  • The Community Role
    • Village halls and other community buildings as an exemplar for the community
    • Parish Council has an important role to develop energy efficient ethos
    • Newsletters carrying energy news
    • Groups providing help for elderly in clearing lofts, lowering ground levels, etc.
  • The Community Role
    • CRI East provides a service to community groups that:-
    • Carries out a survey of community buildings to provide an energy plan which is free
    • a paid for service to train groups to clear lofts and get it ready for insulation
    • a paid for service to help Parish Councils to develop an energy plan for their area and residents
    • Signpost residents to specialists as necessary free of charge.
  • The Community Role
    • CRI East is happy to make a presentation to any community group free of charge to develop interest in energy use and how it can be reduced across Norfolk.
    • Provide bespoke area monitoring forms to show how energy can be saved and monitor future energy use.
  • Renewable Energy Technology
    • The government is hoping to achieve 20% of our energy needs renewably by 2020
    • Micro generation is another name for single home energy generation
    • Can be carried out in a number of ways
    • Grants are not available for this type of work generally, but
    • Other retrospective payments are available
    • For generating electricity renewably
      • Feed in Tariff
        • Already in existence
    • For generating hot water renewably
      • The Renewable Heat Initiative
        • One off grant available now, turns to long term financial benefit next year, 2012
    Renewable Energy Technology
  • Feed in Tariff (FiT)
    • PV Solar Panels
    • Wind Turbines
    • hydroelectricity
    • anaerobic digesters
    • micro combined heat and power (CHP), on trial only

  • The Green Deal
    • Due to be launched in the Autumn 2012, not set in stone as yet!
    • Not a grant, but a loan linked to the home
    • Three step process
    Is the measure eligible ? measure suitability for the property Does it meet the Golden Rule in the property?
  • Heating, ventilation and air conditioning Condensing boilers Heating controls Under-floor heating Heat recovery systems Mechanical ventilation (non-domestic) Flue gas recovery devices Building fabric Cavity wall insulation Loft insulation Flat roof insulation Internal wall insulation External wall insulation Draught proofing Floor insulation Heating system insulation Energy efficient glazing and doors Lighting Lighting fittings Lighting controls Water heating Innovative hot water systems Water efficient taps and showers Microgeneration Ground and air source heat pumps Solar thermal Solar PV Biomass boilers Micro-CHP Measure eligibility
    • The Golden Rule states, ‘Expected financial savings must be equal to or greater than the cost of repayment over the term of the Green Deal Plan’
    • Top up of loan could be asked for if the ‘Golden Rule’ is not met
    • Measures giving best returns for energy saving installed first
    • In some instances use of Energy Company Obligation (ECO) with Green Deal for ‘at risk’ customers
    The Green Deal
    • Paid via energy bills
    • Paid for through the energy savings of the home until the loan has been re-paid
    • The repayment period may be the lifetime of the measure or a specified “pay-back” period
    The Green Deal
  • The Green Deal
    • Debt attached to property and passed to any subsequent owner to pay through their energy bills
    • Usual finance periods of 20 to 25 years for packages of measures
    • Energy efficiency measures show most payback and will be carried out first
  • ECO Subsidy Green Deal Finance Next most cost effective measure Measures fully meeting Golden Rule Measures providing Affordable Warmth to the vulnerable Green Deal working with ECO
  • Energy Company Obligation
    • Requires energy companies to support the installation of energy efficiency improvements to homes
    • Aimed at homes where Green Deal is not likely to work (lower income and vulnerable households)
    • No government finance involved
    • Costs of the scheme will be met equally by all households through their Energy Company tariff.
  • Energy Company Obligation
    • Those properties needing the next most cost-effective measures that do not meet the Golden Rule will be targeted
    • Supporting the
      • Installation of heating
      • Insulation measures
    • Will also support solid wall insulation due to high cost of installation
