BY THE END OF TODAY…… Be confident to do a home visit and carry out: • A). Energy Saving Trust Check • B). Behavioural questionnaire You will able to offer energy saving tips, help with dealing with landlords and generally to inform and inspire the people of Glasgow!
And to make it eveneasier…. You will work in pairs One visit and a phone call There will be ongoing support from your institution or CASP Telephone support from Energy Saving Trust You can always call us
Why Volunteer? • Great CV material • Customer service experience • Technical and administrative experience in Energy Sector • Can appeal to specific disciplines • Career Opportunities • Energy is growing industry- Many future opportunities • Personal knowledge of keeping warm and saving money • Reference • Tell your friends and family!..........
Energy sources for UK electricity generation (DTI, Aug 2007) • Coal 35.8% • Natural Gas 38.8% • Other (oil) 2.1% = Fossil Fuels 76.7% (produce CO2) • Nuclear 18.6% • Renewables 4.7%
Thought Exercise... Imagine: You live in the centre of the city. National instability and difficult economic circumstances has forced the government to announce that the region will loose electricity for a month starting from now. (Its 9pm mid-winter) (Unlikely, I know....but work with me here!)
What would you do first? (Darn, you have got no candles – Spooky huh?) • How would you cook your dinner? • What would you do for entertainment? • How would you keep warm? Ideas??? WHAT WOULD LIFE BE LIKE WITHOUT ALL THIS ABUNDANT ENERGY?
Now let us not forget about the MONEY!!! HEATING, COOKING POWER RATING COST TO RUN FOR ONE HOUR • 3 bar Electric Fire 3000 W 45p • Oil Filled Radiator 500 – 2000 W 8p – 31p • Fan Heater 2000 – 3000W 31p – 45p • Immersion Heater 3000 W 45p • Cooker – 1 ring 1400 W 21p • Oven only 2150 W 32p • Oven & rings 11500W £1.73 • Electric showers 7500 – 12000 W A lot!!!!!!!!!
Targets for CO² Emissions • Kyoto Target - To cut overall emissions of greenhouse gases by 5.2% below 1990 by 2008-2012 • Scottish Government targets: CO2 reduction of 42% by 2020 and 80% by 2050 – one of the most ambitious in the world
Flat Maisonette Bungalow House House examples Question 1
Property positions Question 2 Mid-terrace Semi-detached Detached End-terrace Same principle applies in flats: The more exposed surfaces (outside walls / roof / basement), the greater the heat loss.
Flat Maisonette Bungalow House House examples Post-1950s. Solid concrete walls. Double glazed UPVC Windows. Pre-1900. Solid stone. Single glazed windows. 1900 – 1920s. Single glazed windows. Solid stone walls. 1930s. Brick cavity walls. Upper floor conversions.
HEC Complete details and questions 1-12 Questions?
Wall type & heat loss Question 13 Timber frame: lots of modern builds use this type. Brick: could be solid brick, or could have a cavity. Rarer: Conservatory / garage slows down heat loss from the wall it is attached to. Solid stone: most older properties
Wall type & heat loss Question 13 If your house was built after the 1920s it is likely to have cavity walls. Older houses are more likely to have solid walls If you can see the brickwork on the outside of the house, look at the pattern of the bricks. If your home has cavity walls, the bricks will usually have a regular pattern like this: If your home has solid walls, the bricks will have an alternating pattern like this:
Windows Question 14 -15 Secondary glazing Shutters Shutters and secondary glazing can cut heat loss through window by half to a third Secondary glazing film is cheap and DIY, but single-use Draughtproofing reduces heat loss through gaps around the window
Insulation Question 16 -17 27cm is recommended minimum Cavity wall insulation Draughtproofing Loft insulation Open fireplaces can be blocked-off or a chimney balloon can be installed to exclude draughts.
Where does all the heat go? Where does all the heat go? Loft Insulation saves up to £150 per year 26% More cost effective Double Glazing saves around £135 per year 18% Cavity wall insulation saves around £115 per year 33% Less cost effective 3% Open doors and windows 8% 12% Floor Insulation saves £50 per year Draught Proofing saves £25 per year Source: http://www.energysavingtrust.org.uk/Home-improvements/Home-insulation-glazing June 2009 based on an uninsulated semi-detached 3 bedroom home with gas central heating
Question 18 PrimaryHeating (every room) Electric Storage Heaters Store, then release heat. ‘Wet’ Boiler & Radiators Gas or electric. Rarer: Underfloor Heating Can electric cable or powered from gas boiler. More common in new builds / conversions. Room Heaters Gas or electric. Directly use energy as they heat (peak electricity)
Question 19 Main Heating Fuel Bulk LPG Anthracite Smokeless Coal Bottled gas House Coal
Question 20 Hot water: Boiler & Tank Boiler and tank:‘Normal’ boiler: with linked hot water tank. Boiler but no tank:Combination boiler:fires when hot tap is turned. Can be additional electrical immersion element to ‘top-up’ water heated by a boiler. Tank can be insulated with jacket and pipes with lagging. Rarer: Over the sink instant hot water. Can be gas or electric.
Question 22 Heating controls: Boiler & Radiators Can have any combination of… Timer: to set when heating / hot water is on / off. Room thermostat: to accurately maintain temperature of room / house, when heating is on, by controlling all radiators (fires or turns off boiler). Thermostatic radiator valves: less accurately maintain temperature of a room by controlling an individual radiator. Hotter than 20oC is wasting energy. 1oC cooler = 10% cut in bill On thermostatic valves half way = 18-20oC.
Heating controls: Storage heaters Cheaper electricity at night heats up a ‘brick’ inside the heater which acts as a reservoir. Input switch controls how much heat gets stored overnight Output switch controls how much heat gets let out during the day Boost switch gives more heat directly from electricity during the day (more expensive) Can have thermostatic control like radiators example. If output is turned up at night heat will escape rather than be stored. If input is turned down at night less heat will be stored.
Question 29 Secondary Heating (standalone) Open ‘real’ fire Gas fire Gas/open fire with back boiler Decorative gas fire Electric heaters Bottled gas heaters
Question 31 Showers Mixer shower: takes water from the hot water tank. Electric shower: heats instantly using a lot of electricity.
