Mouse over the different areas of the house to identify the areas of a house most prone to energy leaks. Click on the different areas to find out more information on how to improve the energy efficiency of your home.

Solar Hot Water Panels
Utilize the sun’s free energy to help heat your domestic hot water.
This system typically utilizes a solar collector, often fastened to a roof facing the sun. The sun heats a special fluid that passes through the collectors and into a hot water storage tank inside the house. In a sealed loop, this heat is transferred to the house water, where it is stored for future use.
Solar Thermal installations typically include an auxiliary energy source that is activated when the water in the tank falls below a minimum temperature setting. Hence, hot water is always available.
Solar Photovoltaic (PV) Panels
Converts the suns rays to usable power by means of photovoltaics. The system includes solar PV panels to convert sunlight into electricity, an inverter to convert the output from DC to AC, as well as mounting, cabling, and other electrical accessories. Nowadays, most PV systems are grid-connected.
Operating silently and without any moving parts or environmental emissions, PV systems have developed from being niche market applications into a mature technology used for mainstream electricity generation. Due to the growth of photovoltaics, prices for PV systems have rapidly declined since their introduction.
Attic Ventilation
Proper attic ventilation is critical to help guard against high humidity that could lead to mould, ice dams and icicles. Adequate attic ventilation is achieved through a combination of soffit, roof and gable vents. As part of any attic insulation upgrade, the attic ventilation should be reviewed and upgraded where necessary.
Wall Insulation
Older houses may have little or no exterior wall insulation. Adding wall insulation to your exterior house walls is one of the most effective ways to increase the efficiency and comfort of your home. When you compare the surface area of all the exterior walls in your house, it greatly exceeds the surface area of your ceilings, therefore more heat is typically lost through walls than through the attic.

Low Flush Toilets
Replace older toilets that use large amounts of water with more efficient low flush units. A low flush or low flow toilet uses significantly less water than a full flush toilet. Most low flush toilets use 6 liters, or 1.6 gallons per flush as opposed to the usual 13.2 liters, or about 3.5 gallons. Better yet, many dual flush toilets have a 6 litre and a lower flush. A low flush toilet can help you save money, protect the environment and conserve water.
Crawlspace Insulation
Uninsulated Crawlspace walls result in a lot of heat loss to the exterior. An insulated crawlspace also leads to warmer floors above it.
When insulating the crawlspace, also consider the placement of vapour barrier on unfinished crawlspace floors. Properly sealed, this can significantly reduce the amount of humidity released into the house from your crawlspace.
Faucets
Replacing the aerator at the end of your faucet will reduce water usage and save money. Reduced water usage will also result in reduced load on your hot water heater, both saving energy.
Shower Head
Replacing an older high volume shower head with a low gallon per minute unit, can save a lot of water annually, thereby also reducing the amount of hot water produced, both resulting in savings.
Windows
Windows, doors and skylights can be a significant source of energy loss in your home – up to 35%. Replacing your windows with ENERGY STAR certified units can save a lot on your energy bill. ENERGY STAR models are up to 40% more efficient than standard windows. Buying ENERGY STAR certified doors and skylights will complement your window purchase and help you save even more energy.

Air Sealing - Weatherization
Seal your Leaky House and save energy. Air leakage can account for 25 to 40 percent of the heat lost from an older home.
Cold air leaking into your house can make some rooms drafty, uncomfortable and difficult to heat. Shocks from static electricity, creaky furniture, dry throats and skin, laundry that “clings”: these are symptoms of excessive winter dryness. Cold, dry outdoor air leaking into your house is one of the villains.
Eliminating air-leakage problems with a professional air-sealing job can be the single most cost-effective repair you can make to an older home.
How to Detect Air Leaks
A Registered Energy Advisor can perform a fan depressurization test (also called a blower-door test) to calculate the air tightness of your house and walk around the house with you to identify the location of air leaks.

Ground Source Heat Pump
A ground-source heat pump uses the earth or ground water or both, as the sources of heat in the winter, and as the "sink" for heat removed from the home in the summer. Some systems also contribute to the heating of domestic hot water.
It has two parts: a circuit of underground piping outside the house, and a heat pump unit inside the house. Unlike the air-source heat pump, where one heat exchanger (and frequently the compressor) is located outside, the entire ground-source heat pump unit is located inside the house.
Heating System
The best time to upgrade your heating system is after you upgrade your insulation. In some situations, you may require a smaller heating system. An insulated house loses heat more slowly and does not need as much heat generation to maintain comfort levels.
There are many types of heating systems including furnaces, boilers, heat pumps, etc. Likewise there are many types of fuel sources including natural gas, propane, fuel oil, wood, etc.
Should I Upgrade my Heating System?
To determine whether you should service or possibly upgrade your heating system, contact us to set up an appointment to have your house assessed.
Heat/Energy Recovery Ventilator (HRV/EVR)
A highly efficient well sealed house is desired, however, with less natural uncontrolled airflow into a building, more controlled mechanical ventilation is required to support human comfort. Lack of airflow can cause high humidity, resulting in condensation, mould and bacteria.
HRV's transfers heat from outbound air to the fresh inbound air while ERV's transfer both heat and humidity which is important during the hot humid summer months. ERV's are recommended in predominantly hot and humid climates which we do experience during Canadian summers, for short periods of time relatively speaking.
Do I Need a HRV?
To determine whether your house needs a HRV, contact us to set up an appointment to have your house assessed.
Air Conditioning / Air Source Heat Pump
An air-conditioning system can provide comfort for occupants by lowering the air temperature and the humidity level in the home. Today's ENERGY STAR qualified central air conditioners use up to 20 percent less energy than standard new central air conditioners.
Central air conditioners are cooling-only products, whereas heat pumps provide winter heating as well. Air-source heat pumps draw heat from the outside air during the heating season and reject heat outside during the summer cooling season. Basically, an air source heat pump is an air conditioner with the capability of working in reverse to heat the house.
Should I Upgrade my Air Conditioning System?
To determine whether you should service or possibly upgrade your air conditioning system, contact us to set up an appointment to have your house assessed.
Drain Water Heat Recovery
Recover heat lost down the drain and save energy through the use of a heat exchanger to recover heat energy from drain water from various activities such as dish-washing, clothes washing and especially showers.
A special heat exchanger transfers the heat but keeps the drain water totally separate from the fresh water. This reduces the heating load on your domestic hot water system, saving money.
For a regular household, water heating is usually the second highest source of energy demand.
Domestic Hot Water
There are two primary types of hot water heaters – Tankless (on-demand) and Tank water heaters. Storage tank water heaters as the name implies, stores heated water in a tank. When a tap is turned on, hot water flows from the storage tank.
Tankless (on-demand) water heaters, also called on-demand or instantaneous, only heats water when it is needed, thereby eliminating standby losses associated with keeping a full tank of water warm all the time.

Basement Insulation
A significant amount of heat is lost through your uninsulated foundation walls, into the surrounding soil. In addition, properly sealing the space between the floor joists, above the exterior basement walls and then insulating them can significantly decrease cold air leakage into the house and decrease the heating load on your heating system.

Duct Sealing
Sealing your air supply ducts helps fix uncomfortable hot or cold rooms, improve indoor air quality and lower utility bills. Duct leakage can add up to 30%-40% of the total conditioned air produced by your furnace, air handler and/or air conditioner. The rooms that are furthest from the furnace have the most drastic temperature fluctuation.
Sealed ducts will result in more air flow pressure, allowing rooms to heat or cool to the right temperature in a fraction of time, reducing big temperature fluctuations in your home. This also converts into money savings on your energy bills since your system runs for shorter periods of time and truly works efficiently.
Should I Have my Ducts Sealed?
To determine whether you should proceed with this option, contact us to set up an appointment to have your house assessed.
Duct Cleaning
The air ducts in your home circulate the air from your heating and cooling system into and out of each room. In fact, most of the air in your home circulates through the ducts multiple times a day. The air cycling through your ducts is the same air that you and your family breathe. As such, you want this air to be as clean as possible. Cleaning your ducts results in: a cleaner living environment; reduced allergens and irritants; improves air flow efficiency.
Should I Have my Ducts Cleaned?
You may want to consider cleaning them if you haven’t done so in the past 5 years. Contact us to set up an appointment to have your house assessed.
Sloped Ceiling Insulation
Due to space limitations in this area, the best solution to both insulate and air seal, is the application of spray foam insulation.

To determine whether you should add insulation, contact us to set up an appointment to have your house assessed.
Exposed Floor Insulation
Don’t get cold feet. Add insulation to the underside of your floor to help keep the room above it warmer. For even more impact, utilize spray foam insulation to both insulate and reduce drafts due to air leakage.
Attic Insulation
Increase your attic insulation and reduce your heating & cooling cost, while at the same time improving the comfort of your home. Adding attic insulation to your house is one of the easiest ways to improve energy efficiency due to its ease of access in most homes.
