Tenants in the Fort Street office building were used to the busy street, which caused quite a bit of noise within the facility, as well as being overheated by the sun exposure from the south facing windows.
The building had a mix of 28-year-old single and double pane windows. The owner decided that new replacement windows were in order, and set out to find a company that offered a variety of window pane choices as well as glass coating options. Milgard® Tuscany® Series triple-glazed vinyl windows were selected.

The project lead liked the fact that Milgard custom builds each window to order, allowing a range of double pane, triple pane and coatings. This allowed each replacement window in the building to be selected according to its orientation and use in the room.”
The insulating benefits the windows provided in the cooler months meant the tenants no longer needed personal, electric space heaters to keep warm at their desks. This allowed for less electrical usage in the building and a huge reduction in hydro consumption starting in the fall and lasting through winter.
Year over year hydro consumption. Note that the kWh used to rise in October as winter came on and now it does not.
“I think the insulating values of the triple pane windows, even in our temperature climate, are not properly appreciated,” said Jason Austin, project lead. “I had been a little concerned on these north facing windows if they might reduce the light, but, that was not the case. The slight tinting was pleasant to the eye and the receptionist on the south side, who works with her back to the windows, reported a lot less glare on her computer screen.”
With an office space that is now cooler in summer and warmer in winter, the occupants report that they are more comfortable. “We are extremely happy with or new windows,” says Dimitri, a building tenant at Axis Design. “The difference from before to now is positively dramatic.”
