Fuel Poverty Definition
“A household is in fuel poverty if, in order to maintain an acceptable level of temperature throughout the home, the occupants would have to spendmore than 10% of their income on all household fuel use.”

Impact on the Consumer
Indoor temperature and its effects on
health• 18-24oC, no risk to healthy people• Below 160C, diminished resistance to
respiratory infections• Below 120C, increased blood pressure and
viscosity/strain on cardiovascular system• Below 90C, after 2 or more hours, deep body
temperature falls• Below 60C, place people at risk of
hypothermia (below ‘normal’ core body temp of between 36 – 37.50C (96.8–99.5°F)

Energy efficiency as part of the solution

Energy Efficiency is
Getting the most from the energy we use
And keeping it where it is needed for as long as possible

We don’t flick the switch on to use energy….

For Space and Domestic Hot Water Heating
that means having an

Heating Controls also help to achieve efficiency
and maintain adequate warmth
• Living room 210C• Kitchen 180C• Bathroom 220C• Bedrooms 180C• Hall and Stairs 160C• note: these are suggested minimum temperatures
• Domestic Hot Water 600C

Typical central heating controls
• Programmer
• Room Thermostat
• Thermostatic Radiator Valves (TRVs)
• Cylinder Thermostat

Getting the most from the energy we use
means using low energy lighting
100W bulb used for 1100hours* = 110 kWh i.e. 110 units 110 units x 18.04p per unit = £19.84
*estimated annual use
That’s a saving of over £15.00 per year!
20W CFL used for 1100 hours* = 22 kWh i.e. 22 units
22 units x 18.04p per unit = £3.97 *estimated annual use

18.04p: Power NI July 2013 price of 1 unit incl vat
Going from this
To this
Could save over £60.00 per year(4 x £15.00)
LEDs – more efficient. More expensive to buy but save more
money in the long term.
Of course, the easiest way to save on your lighting bill is simply to turn off the light when you’re not using it. You will
ALWAYS save energy if you turn the light off when you leave the room, even if it’s only for a minute or two.

For appliances getting the most out of the energy we use means replacing old appliances with energy efficient models
and we have many more appliances in our homes today than in the 1970s…..
Typical energy using products in the home over 30 years ago - 17
Typical energy using products in the home today -

Use ‘A’ rated appliances
325kWh x 18.04pthat’s a typical running cost of£58.63 annually

Energy Efficiency is alsokeeping the heat where it is needed
for as long as possible
27
According to the laws of heat exchange, heat will always
move from a warm place to a colder area.
Thus a significant amount of heat in the home can be lost to a
colder outside environment

Keeping the heat where we need itfor as long as possible?
Not Insulated Insulated
30
Cavity Wall Insulation
Reduces heat loss through the walls
•Installation takes less than a day to complete
•Payback: 3 – 4 years
31
Loft Insulation
Reduces heat loss through the roof•Install loft insulation to a depth of 300 mm (approx 12”) and reduce the heat loss through your roof. •Payback: about 2 years (installing 300mm from 0mm))
32
Hot Water Cylinder Jacket
• One of the most cost effective measures available
• Payback: approx. 6 months
33
Draught-proofing gaps around windows, doors, pipes, unused chimneys
Reduce unwanted ventilation heat loss through gaps around doors , windows, etc.•Fit draught proofing•Payback: 2 – 3 years
34
Windows
Reduce the heat loss through the windows with double glazing
•Low emissivity energy efficient glass can reduce heat loss even further
•Payback: + 20 years

A thought……
…..the cheapest unit of energy is the one we don’t use.
