C A S E H I S T O R Y Taking the Heat Off a Vancouver Office Building With 3M ™ Scotchtint ™ Window Film. PROBLEM A 13-story office complex in Vancouver, British Colum- bia, features floor-to-ceiling windows on its entire southern face. And while those windows are an aesthetic asset, until recently, they were a liability to the comfort of the occu- pants in the building once the sun rose over the horizon. According to the building’s property manager, the office complex was originally constructed with windows that offered only minimal solar protection. So once the sun’s rays reached the windows in the morning, the temperature would climb quickly. In addition, there are 15 separate zones on a floor, each governed by a thermostat that automatically goes up or down, depending on the conditions. In response to the heat of the sun, the thermostats closest to the windows would activate the air conditioning—not enough to cool the overheated areas, but more than enough to make room temperatures in areas farther away from the windows uncomfortably cold. SOLUTION Sundog ™ Energy Management Inc. in Vancouver, an authorized 3M Scotchtint window film dealer, was called in to resolve the problem. The company’s owner, William Ross, says, “You could stand by the windows and just feel the heat. I knew we could greatly improve the situation if we could reduce the effects of the sun on the envelope of the building.” Ross recommended LE35AMARL Scotchtint Plus All Season window film to reduce the solar warming in the building and enhance the comfort level of tenants. This low- emissivity film reduces solar heat transmission by as much as 70%, depending on the type of window. The film will also reduce heat loss in the cooler months by as much as 30%. RESULTS “I’m not in business just to sell products,” says Ross. “I’m in business to offer clients the right solution for their specific problems.” Since the installation in 1995, the tenants, especially those who are close to windows, report greater comfort. In addition, the building’s property manager says she estimates that heating and cooling costs for the office complex have dropped by 22% since the installation of 3M Scotchtint window film. And while cosmetics were not the primary concern, she agrees that the film has enhanced the appearance of the building too. A year after Sundog installed 3M Scotchtint window film on the windows of the building’s 13 floors, Sundog was invited back to install 3M Scotchtint window film on the foyer windows. THE 3M DIFFERENCE According to Ross, the installation was a relatively painless procedure. But what’s more important is that, since the installation, the building manager has heard very few complaints about the offices being too warm. 70-0709-0016-5(781)BE Consumer Safety and Light Management 3M Center, Bldg. 223-2S-24 St. Paul, MN 55144-1000 Ph. 800-480-1704 www.3m.com/windowfilm

Vancouver Office Building With

3M™ Scotchtint™ Window Film.

P R O B L E MA 13-story office complex in Vancouver, British Colum-

bia, features floor-to-ceiling windows on its entire southernface. And while those windows are an aesthetic asset, untilrecently, they were a liability to the comfort of the occu-pants in the building once the sun rose over the horizon.

According to the building’s property manager, theoffice complex was originally constructed with windowsthat offered only minimal solar protection. So once thesun’s rays reached the windows in the morning, thetemperature would climb quickly.

In addition, there are 15 separate zones on a floor, eachgoverned by a thermostat that automatically goes up ordown, depending on the conditions. In response to theheat of the sun, the thermostats closest to the windowswould activate the air conditioning—not enough to coolthe overheated areas, but more than enough to make roomtemperatures in areas farther away from the windowsuncomfortably cold.
