100 Homes ProjectBaseline CO2 emissions – what’s our starting point?Updated Jan 2011
Why 100 Homes? Household energy consumption is responsible for 27 per
cent of all carbon emissions. In Britain we use more energy per home than Sweden which is 7°C colder
Energy prices:
Why Muswell Hill? Because we are comparatively environmentally conscious and we are affluent (big footprint but can pay for energy saving measures)
Prices have nearly doubled since 2003 and OFGEM predict that bills could rise by up to 60% by 2020
Survey responses Over 100 households have signed up to 100 Homes 47 completed surveys received by 15 January 2011 60% from N10, 15% from N2, 35% from other post-
codes Average household size 3.1 Since consolidating the data for tonight’s meeting,
we’ve received another 2 surveys We need more data!! Please fill in your survey if
you’ve not already done so. Thanks to everyone who has returned the survey
How do we compare to national averages?
Average CO2 footprint for household energy (gas and electricity) is 6.2 tonnes, for 100 Homes it is 8.5 tonnes – our homes are Gas Guzzlers!Our emissions from air travel are significantly higher than the national average whereas our emissions from cars is below the national averageThere is a wide variation in CO2 footprint across the sample. 32% of households have emissions of more than 20 tonnes per year, including 8% emitting more than 30 tonnes per year. 30% of the sample have emissions of less than 10 tonnes per yearAverage electricity use is 5200 kWh – that’s more than 3 times generated by an average solar photo-voltaic panel installationThere are significant variations in energy use between houses in the same street
National average: 13.0 tonnes CO2 annually
100 Homes: 15.9 tonnes CO2 annually
What measures have people taken? taken so far?Measure How many of us
have installed?
Loft insulation > 200mm 26%More than 50% low energy bulbs
45%
Draughtproofing 19%Double glazing (all or some windows)
38%
Secondary glazing (all or some)
11%
Boiler less than 10 years old
53%
Water meter 21%Solid wall insulation 4%Solar Photovoltaic 13%Solar Thermal 9%
Of people with less than 100 Homes average emissions 61% have taken more than 3 of these measures
Of people with more than 100 Homes average emissions 15% have taken more than 3 measures.
John Skutch – a Case Study• John lives in Halliwick Rd N10• Over the last 5 years he has
radically improved the energy efficiency of his house – mostly through DIY
What’s next? Workshop on behaviour change - today Fill in your ‘pledge sheets’ - today Your volunteer will contact you to discuss
measures you can take – over next 6 weeks Bulk-buying to be put in place (target mid-
October) Further training sessions/meetings - over
the next few months Re-assess how you are doing
