The financial benefits of energy-efficient window coverings are pronounced, especially in a climate like Winnipeg's, which experiences cold winters and warm summers. Below are the ways in which energy-efficient window coverings can result in savings, along with examples and facts sourced from various studies and guidelines:
Insulation and Temperature Regulation:
- Energy-efficient window coverings can significantly enhance the insulation of windows, with many having insulating values of R-2 to R-4. This effectively doubles the insulating value of a standard, premium vinyl window with double-pane glass and a low-E coating. For instance, an average house with 15 windows outfitted with energy-efficient window coverings can achieve an annual energy savings of $1501.
Reduced Heat Loss and Gain:
- During winter, these coverings can reduce heat loss by 40% or more, translating to an energy savings of 10% over the heating season. In the warmer months, cellular shades, a type of energy-efficient window covering, can reduce solar heat gain by 60%. When used year-round, cellular shades can lower your total energy consumption by as much as 15%2.
Overall Energy Savings:
- According to the U.S. Department of Energy, about 30% of a home's heating energy is lost through windows, and during cooling seasons, about 76% of sunlight that falls on standard double-pane windows enters to become heat. By addressing these issues, energy-efficient window coverings can help in regulating temperatures and lowering energy bills. The exact savings would depend on various factors including the type of window attachment, the season, and the climate3.
These statistics demonstrate the substantial cost-saving potential of investing in energy-efficient window coverings, especially in climates with significant temperature variations like Winnipeg. By taking advantage of these coverings, home and building owners can significantly cut down on their energy expenses while also promoting a more comfortable and sustainable living environment.
