100 Homes Project Baseline 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 average  There 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 year  Average electricity use is 5200 kWh – that’s more than 3 times generated by an average solar photo-voltaic panel installation  There 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? MeasureHow 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 YearMeasures 2005 Start secondary glazing, draughtproofing, 2006 Install 270mm loft insulation. Install double glazing for 2 windows, replace refridgerator, start change over to low- energy bulbs 2007 Install condensing boiler and solar thermal system 2008 Internal wall insulation (1 bedroom wall) Seal gaps in timber ground floor 2009 Complete programme of secondary glazing, change supplier to Ecotricity 2010 Start programme of low-cost 270mm thick sub-groundfloor insulation

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
