1. INTRODUCTIONTO

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 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?

You’ll be interested to know that for individuals, about 40% of our carbon

emissions come from our homes.

And that’s where you come in!

It is estimated that one third of this energy is wasted.

This costs the UK £5 Billion a year and is destroying our planet!

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!!!!!!!!!

So what can we do?

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

LETS START FUTURE PROOFING NOW.

House examples

House

Question 1

Detached Mid-terrace Semi-detached

End-terrace

Property positions

Same principle applies in flats: The more exposed surfaces (outside walls / roof / basement), the greater the heat loss.

Question 2

Flat Maisonette

Pre-1900. Solid stone.Single glazed windows.

Post-1950s.Solid concrete walls. Double glazed UPVC 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

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 lossQuestion 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:

Windows

Secondary glazingShutters

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 14 -15

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.

More cost effective

Less cost effective

Where does all the heat go?

Primary Heating (every room)

Electric Storage Heaters

Store, then release heat.

Room HeatersGas or electric.Directly use energy as they heat (peak electricity)

Rarer: Underfloor HeatingCan electric cable or powered from gas boiler.

More common in new builds / conversions.

‘Wet’ Boiler & Radiators

Gas or electric.

Question 18

Boiler TypesQuestion 20

Condensing combination

Combination Condensing Normal

What can you see?

A boiler + a storage tank A white box + NO hot water tank

Look at boiler - Plastic pipe coming out white box?

Look at boiler - Does it have a plastic pipe coming out?

Yes No Yes No

Condensing boiler:middle plastic pipe

Main Heating FuelQuestion 19

Bottled gas

Anthracite

Bulk LPG

House Coal

Smokeless Coal

Boiler and tank: ‘Normal’ boiler: with linked hot water tank.

Boiler but no tank: Combination boiler: fires when hot tap is turned.

Hot water: Boiler & Tank

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

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.

On thermostatic valves half way = 18-20oC.

1oC cooler = 10% cut in bill

Question 22

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)

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.

Gas fire

Open ‘real’ fire

Decorative gas fire

Gas/open fire with back boiler

Bottled gas heaters

Secondary Heating (standalone)

Electric heaters

Question 29

Showers

Mixer shower: takes water from the hot water tank.

Electric shower: heats instantly using a lot of electricity.

Questionnaire

Free Home Energy and Carbon Monitoring Calculator

What about carbon?

Night club ventilation system 10,000 WAir conditioning cassette 3,500 WDairy deck fridge 2,500 WElectric heater 2,000 WBottle fridge 900 WWater cooler (NB: when cooling) 750 W1 x standard tungsten filament (TFL) bulb 100 W1 x energy efficient bulb 11 WMobile phone charger on standby >1 W

• 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 CO2 released into the atmosphere per kWh of electricity is:

0.543 kg (DEFRA’s new figure*).

What about carbon?

* 0.54303kg - June 2009 guidelines

602 kWh/year x 0.543 kg = 327 kgCO2/year

So this little fridge is responsible for 0.3 tCO2/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– Available supply capacity (maximum demand)

602 kWh/year x £0.12 =

£72.24 per year

So this little fridge will cost around £72 to run a year

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 = £807.84

Carbon? 6732kWh x 0.543kg of CO2 = 3655.5 kg of CO2

= 3.6 tonnes of CO2
