How specifiers brought LLLC to the Associated General Contractors of Washington building

When it comes to lighting retrofits for large multi-space commercial buildings, relationships aren’t just important between operating systems, but also between the people writing the specifications, doing the implementation, and performing the maintenance—and their local utility. It’s why Seattle City Light stepped up to help the Associated General Contractors of Washington’s (AGCW) facilities manager and electrical contractor with their LLLC project.

Secondary windows rejuvenate 1970s office building

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.

Class-A office building finds grade-A booster pump solution

When Urban Renaissance Group purchased Tower 333, a 20-story office building in Bellevue, Wash., they knew the aging and inefficient water-booster system needed to be replaced. The original system consisted of three 20-horsepower constant-speed booster pumps operated in a staged sequence, bringing on successive pumps as demand changed. With a commitment to occupant comfort and maintaining the building's energy efficiency certifications, the company knew they had to find a replacement for the aging water-booster system that would save energy and improve performance.
