Improving building envelope and reducing drafts
Efficiency heating and cooling
Reducing lighting and water use
Using appliances efficiently
Energy Saving
Actions
One-time changes
Example: changing a light
bulb, motor or appliance to
be more efficient.
Repetitive practice
Example: turning off
equipment to conserve
energy.
Improving Building Envelope
BUILDING ENVELOPE : the exterior of your
building that protects the interior from the elements.
This includes the walls, roof and windows.
Air leakage in the building envelope can
be responsible for up to 45% of overall
heat loss.
Identify and seal drafts in windows, doors,
electrical outlets, light switches, on exterior
walls, pipe entry points, etc...

Seal the drafts with caulking and weatherproofing.
Winterize windows with shrink-able insulation film or
magnetic windows.
• Caulk your windows, weatherproof your doors
Seal outlets and light switches with caulking and
foam gaskets. Plug outlets with safety covers.
• Seal up electrical outlets on exterior walls

Efficient Heating and Cooling
With some simple adjustments and some
changes in practices you can increase the
efficiency of your heating and cooling
system by 5% to 40%.
Clean the filter of your heating and ventilation
system regularly.

Efficient Heating and Cooling
Install programmable thermostats and program
them to suitable temperatures for the seasons.
Efficient Heating and Cooling
Dress for the weather. Consider keeping extra
sweaters around for the winter.

Efficient Heating and Cooling
Close the curtains when it’s hot and sunny, open
them when it’s cold and sunny.

Efficient Heating and Cooling
Open windows
and use fans in the
summer to circulate
air instead of using
an air conditioner.
Efficient Heating and Cooling
Improving lighting and
water use
Lighting accounts for about 11% of electricity use in
Canadian homes.
Make it easier to use fewer lights. Use task lighting and
natural lighting.
Improving Lighting and Water Use
Change your light bulbs to LED
Improving Lighting and Water Use
Keep your water heater
at 54°C (below could
increase bacteria growth,
above is inefficient). Get a
professional to do this.
Install low-flow and
cut-off showerheads
and faucet aerators.
Improving Lighting and Water Use
Install a hot water
tank blanket and
pipe insulation on
the hot water pipes.
Improving Lighting and Water Use
Install low-flow
and cut-off
showerheads
and faucet
aerators.
Improving Lighting and Water Use
Place a bottle filled with water or a toilet
tank bank or dam in the tank of your toilet.
Improving Lighting and Water Use
Appliances and Equipment
PHANTOM LOAD: The energy an appliance uses
when it is “off”. Many appliances are using electricity
even when they are turned off.
Measure the Power Usage of your appliance – measure the
difference between on and off.

How are Amps, Volts and Watts
related ?
Amps (A) = electric current
(flow of electrons).
Volts (V) = electromotive
force (like pressure)
Watts (W) = power (energy
per second)
Watts = Amps x Volts
Energy (kWh) = Watts x
How to calculate savings?
Energy (kWh)
= (Watts x Hours)/1000
Cost ($) = kWh * $/kWh
Example: 50 W on 24/7
How to calculate savings?
Energy (kWh)
= (Watts x Hours)/1000
Cost ($) = kWh * $/kWh
Example: 50 W on 24/7
50 W * 8760 h / 1000 W/kW
= 438 kWh * 0.15 $/kWh
= $65.70 per year
Use a power bar to turn off equipment that is not in

Refrigerator checklist:
 Is it older than ten years old?
 Do you need this one on all
year?
 Check for leaks around the
door.
 Clean the condenser coils.
 Give fridge 2-3 inches space
on top, sides and behind
 Keep it well-stocked but not
too full.
 Turn off the ice-maker

Computer checklist
 Use energy saver settings.
 Do not use screen savers
 Use sleep state if you
leave for less than 30 min.
 Power down if you leave
for more than 30 minutes.
 Use an LCD screen.
 Connect devices to a
power bar to turn off.
 A laptop uses less energy
than a desktop.
