Built in 1975, Hurley Development’s 915 Broadway office building in downtown Vancouver, Wash., features floor-to-ceiling windows in every perimeter office—6,000 sq. ft. of windows in total. While all of these single-pane windows let in a vast amount of natural light, they also brought in far too much heat in summer, and too much cold air in winter. This thermal leakage not only led to tenant comfort complaints, it also inflated energy costs by forcing the aging HVAC equipment to strain to maintain indoor temperatures.
With tenant comfort a top priority, Hurley Development committed to finding a solution to solve the thermal leakage caused by so many thin, single-pane windows. When a full window replacement was quoted at $2–3 million dollars (almost as much as the building is worth), Hurley Development pivoted to a much more affordable and feasible option to solve their comfort and energy-cost issues: Secondary windows.

“I’d definitely recommend secondary windows. The installation was painless and they’re performing exactly the way we expected them to. I don’t know why you wouldn’t want to consider this for your commercial building.”
