Heat Pumps
-
Heat pumps are versatile heating and cooling systems that transfer heat from one place to another. They can extract heat from the air, ground, or water and use it to heat or cool a building efficiently.
-
Types of heat pumps:
(1)Air Source Heat Pumps (ASHP): These are the most common type and extract heat from the outside air. They can be further divided into Air-to-Air Heat Pumps that transfer heat between the air inside and outside and Air-to-Water Heat Pumps that transfer heat to water for heating systems.
(2) Ground Source Heat Pumps (Geothermal): These systems extract heat from the ground. They are more efficient than air-source pumps, especially in extreme temperatures, but they require more extensive installation.
(3) Water Source Heat Pumps: These systems use a body of water (like a lake or well) as a heat source or sink.
Advantages: Heat pumps can be 3-4 times more efficient than traditional heating systems. They can both heat and cool spaces and reduce reliance on fossil fuels, making them more environmentally friendly. If properly maintained, heat pumps can last 15-20 years or more.
Important considerations before buying:
SEER (Seasonal Energy Efficiency Ratio): Measures the cooling efficiency of air conditioners and heat pumps over a typical cooling season. Higher SEER ratings indicate better efficiency.
HSPF (Heating Season Performance Factor): Measures the heating efficiency of heat pumps over a typical heating season. Like SEER, higher HSPF ratings indicate better efficiency. Having a good HSPF rating is important for colder climates.
Ducted vs. Ductless Ratings: Ducted systems may have additional ratings related to duct efficiency and airflow. Mini-split systems may have specific ratings for indoor units, including noise levels and airflow efficiency.
Refrigerant Type: The type of refrigerant used (e.g., R-410A, R-32) can impact efficiency and environmental impact. Some refrigerants have lower global warming potential (GWP) and are more environmentally friendly.
Heating Capacity (BTU/h): This rating indicates the amount of heat a heat pump can provide, measured in British Thermal Units per hour (BTU/h). It's crucial to size the heat pump correctly to ensure it meets the heating and cooling needs of the space.
Cooling Capacity (BTU/h): Similar to heating capacity, this measures the cooling output of the heat pump. Again, ensure that the system can adequately cool the space during warmer months.
Certifications: Make sure the Heat pump complies with the Canadian Standards Association (CSA).

The cost of heat pumps varies widely based on type, size, and installation complexity.
Generally, air-source heat pumps range from $3,000 - 8,000, while geothermal systems can cost between $10,000 - $30,000 or more.
Installation costs can add significantly to these prices.

Air Conditioners
-
Energy Star air conditioners are cooling systems that meet strict energy efficiency guidelines set by the Government of Canada.
These units are designed to use less energy while providing the same level of cooling comfort as standard models, which can lead to lower utility bills and reduced environmental impact.
-
Types of air conditioners:
(1) Central Air Conditioners: These systems cool the entire home through ductwork. They are ideal for larger spaces and can be more efficient than individual units.
(2) Ductless Mini-Split Systems: These are suitable for homes without ductwork. They consist of an outdoor compressor and one or more indoor air-handling units, providing flexibility in cooling specific areas.
(3) Window Air Conditioners: These units are installed in a window and are suitable for cooling single rooms. They are generally more affordable and easier to install.
(4) Portable Air Conditioners: These are movable units that can be used in different rooms. They typically require a window for venting hot air.
Certification/labels: Look for the Energy Star label. Energy Star units use 10-50% less energy than standard models.
-
The price of Energy Star air conditioners can vary widely based on type, size, and brand. Generally, you can expect:
Window Units: $150 to $600
Portable Units: $250 to $800
Ductless Mini-Split Systems: $1,500 to $5,000 (including installation)
Central Air Conditioners: $3,000 to $7,000 (including installation)

Window Film
-
Removable tinted window films are a type of window film designed to reduce the amount of UV radiation/ heat coming through the window.
-
Look for ones specifically designed to reduce the amount of heat coming through the windows, as some films are used for privacy.
Look for a film that has a higher solar heat gain coefficient (SHGC) rating, which indicates better heat rejection. Ensure the film blocks UV rays, ideally 99% or more.
Make sure the film is removable - you will want to remove it in the winter months in order to take advantage of passive heating.
-
Expect to pay anywhere from $5 to $15 per square foot depending on the features.

ENERGY STAR® Windows
-
Energy Star windows are more efficient than other windows. They are better at keeping cold air out in the winter, and hot air out in the summer, which will keep your home comfortable and bills down.
-
Look for the energy star label. Make sure any windows are CSA approved. Check the NFRC label to compare the performance of different products.
-
The cost of windows varies widely based on type, size, and number of glazings. Average prices can range from $150- $1400.

EfficiencyPEI’s Home Insulation Rebate Program offers rebates of up to $125 on EnergyStar windows, doors and skylights.
Insulation
-
Insulation slows the movement of heat between the inside and outside of the building. R-value is a numerical measure of an insulation material’s ability to resist heat flow. The higher the R-value, the better the insulation performs.
-
Some common types of insulation:
1. Fiberglass: R-Value: Approximately R-2.9 to R-3.8 per inch. This insulation is non-combustible, resistant to moisture, and widely available. It can be installed in various forms (batts, rolls, loose-fill). It can irritate skin and lungs so installation requires protective gear. Performance can be reduced if compressed or wet.
2. Foam Board: R-Value: R-4 to R-6.5 per inch, depending on the type (polystyrene, polyisocyanurate). This insulation has a high insulating value for relatively thin material, is moisture-resistant, and can be used in various applications (walls, roofs, foundations). It can be more expensive than other options; some types can be flammable and require a thermal barrier.
3. Spray Foam : R-Value: R-6 to R-7 per inch. Excellent air sealing properties, expands to fill gaps, and provides a high R-value, but requires professional installation and can off-gas chemicals during curing.
4. Cellulose: R-Value: R-3.1 to R-3.7 per inch. This insulation is a good air barrier. Made from recycled materials, it can be blown into existing walls. It can settle over time though, potentially reducing effectiveness.
5. Mineral Wool (Rock Wool) Insulation: R-Value: R-3.0 to R-4.0 per inch. This insulation is fire-resistant, has soundproofing qualities, and does not absorb water. It is heavier than other insulation types, can be more expensive and may require protective gear during installation.
Additional Considerations:
R-Value: Whatever kind of insulation you choose, check the R-value. The higher the R-value, the better the insulation’s ability to insulate.
Installation: Proper installation is crucial for all types of insulation to achieve their rated R-values.
Building Codes: Check local building codes for minimum insulation requirements.
Air Sealing: Insulation works best when combined with air sealing to prevent drafts and heat loss.
-
1. Fiberglass Insulation cost: Around $0.50 to $1.50 per square foot
2. Foam Board Insulation cost: Approximately $1.00 to $3.00 per square foot
3. Spray Foam Insulation cost: About $1.50 to $3.00 per square foot
4. Cellulose Insulation cost: Approximately $0.60 to $2.00 per square foot
5. Mineral Wool (Rock Wool) Insulation cost: Around $0.70 to $2.00 per square foot
6. Reflective or Radiant Barrier Insulation cost: Approximately $0.10 to $0.50 per square foot

Awnings
-
Awnings are external coverings that are typically made of fabric or metal and are attached to the exterior of a building, usually above windows, doors, or patios.
-
Awnings provide shade from the sun, helping to keep indoor spaces cooler and reducing glare. When installing awnings, you need to take into account the pitch or slope of the awning. This is important for water drainage and to maximize shade.
A steeper pitch can provide better rain runoff but may reduce the amount of shade.
A common recommendation is a pitch of 15 to 45 degrees. The direction the awning faces will affect its effectiveness. South-facing awnings provide the most shade during the hottest parts of the day, while east and west-facing awnings can help with morning and afternoon sun.
Consider the size of the area you want to cover. Measure the space accurately to ensure the awning fits well and provides adequate coverage.
Consider the weather conditions - areas with heavy snowfall may require sturdier awnings.
-
The cost of awnings can vary widely based on size, material, and installation complexity. On average, you might expect to pay:
Retractable Awnings: $1,500 to $3,500
Fixed Awnings: $300 to $1,500
DIY Options: $100 to $500 for materials if you choose to install it yourself.
