The Amec Building, a thirteen-story office complex in
Vancouver, British Columbia, features floor-to-ceiling
windows on its entire southern face. And while those
windows are an aesthetic asset, they were a liability
to tenant comfort.
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 quickly rise.
In addition, there are fifteen 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.
Sundog Energy Management Inc. of Vancouver, a
3M-authorized Dealer Applicator, was called 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 also reduces heat loss in the cooler months by
as much as 30%.
"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
closest to the 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 thirteen floors, Sundog was invited
back to install Scotchtint on the foyer windows.
According to Ross, the installation was a relatively
painless procedure. But what is more important is that
since the installation, the building manager has heard
very few complaints about the offices being too warm.
