40 house context
40% House - context
  • Four objectives of Energy White Paper 2003:
  • 60% reduction in carbon dioxide by 2050
  • adequate and affordable warmth
  • security of supply
  • competitiveness
  • Likely changes in population and climate

best practice needs to improve
‘Best Practice’ needs to improve
  • Gallions Ecopark
  • Ecohomes ‘excellent’
  • Space heating energy consumption ~ 8,200 kWh/year
  • New build average needs to be 2,000 kWh
  • Ecohomes ‘excellent’ is an inadequate standard for new-build

how to do it theory
How to do it - theory
  • Target property transactions as the key opportunity
  • Make the costs more attractive/bearable
  • Improve quality of workmanship: massive training and recruitment drive for installers
  • Monitor and report consumption
  • Get people to adopt conserving behaviour

theory into practice opportunity
Theory into practice: Opportunity

40% House project – achieving 60% cuts in residential sector CO2 emissions by 2050

theory into practice cost
Theory into practice: Cost
  • Grants = £100’s
  • Costs = £1,000’s
  • Owner-occupiers - need incentives to make it mainstream (eg Stamp Duty rebates)
  • Private rented sector – need to regulate
  • Public sector – need a tough refurbishment standard: public sector can stimulate markets by being a demanding client

theory into practice monitoring reporting
Annual energy use:

Gas = 10,750 kWh

Elec = 1,550 kWh

Annual CO2 emitted:

2.8 tonnes total

1.4 tonnes per person

0.03 tonnes per m2

Theory into practice: Monitoring & Reporting

theory into practice conserving behaviour
Theory into practice: conserving behaviour
  • Education & awareness-raising still needed
  • Widespread ownership of LZCs may help
  • Peak oil, peak gas = price rises, cuts?
  • A minority of citizens care enough to ‘do their bit’ but infrastructure is lacking
  • Better metering/billing can change behaviour
  • Do we need a policy framework for demand reduction, eg carbon allowances?

40 house scenario 2050
40% House scenario, 2050
  • 67 million people in smaller family units
  • 22m homes refurbished, 3m demolished, 10m new
  • Energy demand reduced beyond the currently cost effective
  • 54m LZCs in homes & neighbourhoods = 16 x Didcot power station
  • Diversity of technologies = security of supply
  • No reliance on nuclear or remote renewables to meet residential sector demand

policy issues i
Policy issues - I
  • Needs strong leadership and a coherent policy framework
  • Tighter building regulations and compliance
  • Planning policies require 100% energy from on-site renewables by 2020
  • Include shading devices as energy-savers
  • Strong EU policies establish energy conservation as product design principle

policy issues ii
Policy issues - II
  • 54m LZCs in homes & neighbourhoods = 16 x Didcot power station
  • Huge skills gap and employment potential
  • Diversity of technologies = security of supply
  • No reliance on supply-side ‘fixes’ to meet residential sector demand (new nuclear, remote renewables)
  • Decentralised energy generation implies more devolved government and more engaged population
