Would you like to save on electricity bills?
Here’s how you can
Efficient window coverings and interior window treatments can reduce energy loss through the windows, lower heating and cooling bills, and improve home comfort while also saving on electricity bills.
About 30% of a home’s heating energy is lost through windows. In cooler seasons, about 76% of sunlight that falls on standard double-pane windows enters to become heat.
Most types of window treatments will result in energy savings, but the exact savings will depend on the type of attachment, the season, the climate, and how the attachment is used.
Operable Window Coverings
Operable window coverings give you the flexibility to choose whether to keep your window coverings open or closed for privacy, and to maximize natural light, take advantage of heat from the sun in the winter, and reduce heat gain in the summer. Options include shades, blinds, draperies or curtains, and shutters. These too can help to save on electricity bills.
Operation of Window Coverings
Not all window coverings are operable, but of those that are, one study found that 75% of residential window coverings remain in the same position every day. If this describes your habits, be strategic about which coverings you open in the morning. The right decision can help to save on electricity bills.
If it’s winter and likely to be sunny, open the blinds or curtains in the morning to allow the sun to heat your home through the day—especially those that receive direct sunlight.
In the summer, you may want to keep certain window coverings closed to reduce heat gain. For natural light, open those coverings that don’t get direct sunlight.
You may also want to try switching the ones that are opened and closed through the day to maximize light and heat from the sun when you want it.
Interior Window Treatments how they can save on electricity bills
Roller or Roman Shades, Interior Window Coverings
Roller shades are usually inexpensive shades that are raised or lowered from a roller bar fitted at the top of the window. Roman shades are fabric window shades that are drawn up into a series of evenly stacked folds when raised or lowered.
These shades typically fit inside of the window casing, or just outside, and they come in a variety of fabrics, colours, and weaves. Heavier fabrics will typically offer slightly better thermal performance, but roller and roman shades offer only a small amount of insulation and are most effective for privacy, room darkening, and blocking sunlight.

Blinds, an effective way to save on power bills.
Window blinds—vertical or horizontal slat-type —are more effective at reducing summer heat gain than winter heat loss. Because of the numerous openings between the slats of blinds, it’s difficult to control heat loss through interior window blinds, but the slats offer flexibility in the summer. Unlike shades, you can adjust the slats to control glare, light, and solar heat gain. When completely closed and lowered on a sunny window, highly reflective blinds can reduce heat gain. Horizontal slat-type blinds (Venetians and Shutters) can also be adjusted to block and reflect direct sunlight onto a light-coloured ceiling. A light-coloured ceiling will diffuse the light without much heat or glare while allowing you to take additional advantage of natural daylighting.

Save on power bills with Exterior Shutters and Shades
Exterior shutters and shades are usually made of a variety of materials, including fabric, wood, steel, aluminium, or vinyl. They are most effective at reducing solar heat gain.
Shades are typically fabric or vinyl and the material may have openings that allow some visibility through the window. The larger the openings, the less protection from solar gain. They are usually manually operated, though some can be opened or closed with a crank inside the home.
Roller shutters are usually mounted above the window and side channels guide them as they’re lowered and raised. When you lower these blinds completely, their slats meet and provide shade, privacy, security, and protection from storms. If partially raised, the blinds allow some air and daylight to enter through windows.
Most exterior shutter systems include a mechanical crank, rod, or motor to allow operation from indoors. This can help encourage daily use of the shutters and may be required by local fire codes.

Awnings and how they can reduce power bills.
An awning is a roof-like shelter installed on a home’s exterior that shades windows from the sun’s heat and glare. Awnings can also shade outdoor living spaces. Awnings can be fixed or retractable.
Window awnings can reduce solar heat gain in the summer by up to 65% on south-facing windows and 77% on west-facing windows. You can use an awning to shade one window or have an awning custom-made to shade the entire side of your house. This can be a very effective way to use awnings to save energy
In the past, most awnings were made of metal or canvas, which need to be recovered every five to seven years. Today, awnings are made from synthetic fabrics such as acrylic and polyvinyl laminates that are water-repellent and treated to resist mildew and fading. Whatever the fabric, you should choose one that is opaque and tightly woven. A light-coloured awning will reflect more sunlight.
Awnings require ventilation to keep hot air from becoming trapped around the window. Grommets (eyelets) or other openings along the tops and sides of an awning can provide ventilation. The awning may also open to the sides or top to vent hot air.
While awnings can save energy during the cooler seasons, they can increase the energy used for heating, so keep this in mind when deciding whether awnings are right for you. You can also adjust your use depending on the season: keep awnings installed or closed in the summer and remove or open awnings in the winter. Fixed awnings can sometimes be installed to allow the lower-angle winter sunlight to reach windows.
You can roll up adjustable or retractable awnings in the winter to let the sun warm the house. New hardware, such as lateral arms, makes the rolling up process quite easy. Some awnings can also be motorized for easy operation.
Drop Arm Awnings give great sun protection and can save money on electricity bills as well
