Personal knowledge of keeping warm and saving money. Practical life skills! Reference from the university – volunteering appears on your transcript!

2. INTRODUCTION TO ENERGY

You know your shoe size but do you know your carbon footprint?

Where does our Carbon Footprint come from? Food Waste Travel Energy

Energy sources for UK electricity generation (DTI, Aug 2007) Coal 35.8% Natural Gas38.8% Other (oil) 2.1% = Fossil Fuels 76.7% (produce CO2) Nuclear 18.6% Renewables 4.7%

Renewables: No need to worry? Current energy and resource consumption rate unsustainable!

Renewables: No need to worry? Useful video: Technology ≠ Energy! Current economic system requires endless growth – constantly increasing energy consumption – more oil reserves …but no one is questioning the fact that we’re living in an exponential growth model with a finite resource base… The American dream: Move towards a low-energy society?

For individuals, about 40% of our carbon emissions come from our homes.

And that’s where we come in! It is estimated that one third of this energy is wasted. This costs the UK £5 Billion, not to mention the environmental damage!

Targets for CO² Emissions Kyoto Target - To cut overall emissions of greenhouse gases by 5.2% below 1990 by Scottish Government targets: CO2 reduction of 42% by 2020 and 80% by 2050 – one of the most ambitious in the world

3. Getting to know your home

Where does all the heat go? Roof Windows Open doors and windows Walls Through the floor Draughts

Cavity wall insulation saves around £115 per year 12% 33% 18% 26% 8% Loft Insulation saves up to £150 per year Double Glazing saves around £135 per year Floor Insulation saves £50 per year Draught Proofing saves £25 per year Where does all the heat go? Source: June 2009 based on an uninsulated semi- detached 3 bedroom home with gas central heating 3% Open doors and windows More cost effective Less cost effective Where does all the heat go?

Detached Mid-terraceSemi-detached End-terrace Property Types The more exposed surfaces (outside walls / roof / basement), the greater the heat loss. Question 2 Flat

Pre Solid stone. Single glazed windows. Post-1950s. Solid concrete walls. Double glazed UPVC Windows. Age of property 1900 – 1920s. Single glazed windows. Solid stone walls. 1930s. Brick cavity walls. Upper floor conversions.

Wall type & heat loss Brick: could be solid brick, or could have a cavity. Solid stone: most older properties Timber frame: lots of modern builds use this type. Rarer: Conservatory / garage slows down heat loss from the wall it is attached to. Question 13

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 your home has solid walls, the bricks will have an alternating pattern like this: 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:

Insulation Loft insulation Draughtproofing Cavity wall insulation 27cm is recommended minimum Open fireplaces can be blocked-off or a chimney balloon can be installed to exclude draughts. Question

Windows Secondary glazing Shutters Shutters and secondary glazing can cut heat loss through window by half to a third Draughtproofing reduces heat loss through gaps around the window Secondary glazing film is cheap and DIY, but single-use Question

Heating Electric Storage Heaters Store, then release heat. Room Heaters Gas or electric. Directly use energy as they heat (peak electricity) Rarer: Underfloor Heating Can electric cable or powered from gas boiler. More common in new builds / conversions. ‘Wet’ Boiler & Radiators Gas or electric. Question 18

Main Heating Fuels Bottled gas Anthracite Bulk LPG House Coal Smokeless Coal Gas Electricity

‘Wet’ Boiler & Radiators May have a water tank or may not. Gas Central Heating Gas Boiler (does it have a blue flame?) Wet radiators Hot water tank or cylinder TRV

Electric Central Heating Storage Heaters Electric ‘Wet’ Radiators Input /output control Electric wet heating will not give instant water. Emersion tank needed

Gas fire Open ‘real’ fire Decorative gas fire Gas/open fire with back boiler Bottled gas heaters Secondary Heating (standalone) Electric heaters Question 29

Heating control: 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 20 o C is wasting energy. On thermostatic valves half way = o C. 1 o C cooler = 10% cut in bill Question 22

Heating Control: Storage Heaters Cheaper electricity at night heats up a ‘brick’ inside the heater which acts as a reservoir. Look for DUAL-TARIFF on bill. 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) If output is turned up at night heat will escape rather than be stored. Can have thermostatic control like radiators example. If input is turned down at night less heat will be stored.

Boiler Types Question 20 Condensing boiler: middle plastic pipe

Boiler and tank: ‘Normal’ boiler: with linked hot water tank. Boiler but no tank: Combination boiler: fires when hot tap is turned. Hot water Tank can be insulated with jacket and pipes with lagging. Can be additional electrical immersion element to ‘top-up’ water heated by a boiler. Rarer: Over the sink instant hot water. Can be gas or electric. Question 20

Showers Mixer shower: takes water from the hot water tank. Electric shower: heats instantly using a lot of electricity. Question 31

Insulation Heating Water Washing Lighting Cooking Appliances So what can we do?

What about carbon?

If you know how many kWh you use (appliances, energy tracker, meter or bills) it is very easy to calculate a ‘carbon footprint’. The average volume of CO 2 released into the atmosphere per kWh of electricity is: kg (DEFRA’s new figure*). What about carbon? * kg - June 2009 guidelines

602 kWh/year x kg = 327 kgCO 2 /year So this little fridge is responsible for 0.3 tCO 2 /year

£££ cost of electricity Gone up 65% in last 4 years!! Heading one way A typical current campus cost is 12p / kWh Consider: –Day and night (12am to 7am) rates

602 kWh/year x £0.12 = £72.24 per year So this little fridge will cost around £72 to run a year

Night club ventilation system10,000 W Air conditioning cassette 3,500 W Dairy deck fridge2,500 W Electric heater 2,000 W Bottle fridge900 W Water cooler (NB: when cooling)750 W 1 x standard tungsten filament (TFL) bulb100 W 1 x energy efficient bulb11 W Mobile phone charger on standby>1 W

Calculating energy consumption A Cafe has 44 x 50W tungsten filament halogen bulbs in the seating area. They are on for 10 hours, 6 days a week for 51 weeks a year. (Their average tariff for electricity is £0.12 per KWh) What is the value of the energy they consume in a year? » And what is their carbon footprint? Example – Halogen bulbs in a Cafe

Hours open per year? 10hours x 6 days x 51 weeks = 3060 hours per year. Watt hours per year? 50 W x 3060 hours = 153,000 watt hours per bulb per year. 44 bulbs x 153,000 = 6,732,000 watt hours per year. kWh’s per year? 6,732,000 watt hours / 1000 = 6,732 kWh Cost? 6732kWh x £0.12 = £ Carbon? 6732kWh x 0.543kg of CO 2 = kg of CO 2 = 3.6 tonnes of CO 2
