The Heat Is On (continued)
Upgrade to multi-glazed windows with low-emissivity coatings.
Workplace windows should have at least two layers of glass with an inert gas (e.g., argon) sandwiched between the layers. Normal double-glazed windows have an R-value (i.e., the ability of material to resist the transfer of heat) of 2.0; triple-glazed windows provide an R-value of 6.0. These windows should have insulated edge spacers to reduce condensation, insulated frames, and low emissivity coatings that reduce heat loss from within and allow solar energy to enter. Multi-glazed windows not only prevent heat from escaping, they also prevent the entry of unwanted heat from the summer sun. Because of their thickness, multi-glazed windows reduce the effect of road noise and are harder to break than single-pane windows.
Maximize the return on your window investment by understanding the benchmark ratings established by the Canadian Standards Association (CSA). For instance, air tightness is measured from A1 to A3, water tightness rated from B1-B7, and wind load resistance from C1 to C5. The higher the number within each measurement category, the better the window.
To supplement new high-R and CSA-rated windows, you may be well advised to invest in curtains and blinds especially if your building has extreme window exposure to sun and cold winds. Curtains minimize the intrusion of heat from the sun and take pressure off the cooling system. During cold winter days, the curtains can be opened to allow the sun’s energy to augment the heating system or closed to retain the heat on cloudy days.
Reduce Your Carbon Footprint
Controlling the heating and cooling of your premises with smart thermostats and retrofitting of windows and window coverings are excellent ways of reducing the high cost of energy use while reducing your carbon footprint.
Most provinces have programs that help small businesses conserve energy and therefore reduce operating costs. Check with your provincial energy agency to save energy through appliance and equipment upgrades, building enhancements and by educating your employees about the need for proper maintenance and more efficient use of existing equipment or lighting.
