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.
Providence Down Manor is an independent retirement community in Hood River, OR. To increase efficiency while maintaining high comfort standards for its residents, the facility installed hot water pumps with smart circulators, which have integral controls that self-regulate the speed of the pump to match the needs of the system, adapting to pressure or flow requirements and reducing power when demand is lower.
Bellwether Housing is the largest nonprofit affordable housing provider in Seattle, managing 2,100 units across the city in buildings that range from new construction to century-old apartments. This diversity can pose a challenge for the maintenance team, so when the opportunity arose to upgrade some hot water recirculation pumps to efficient and adaptive smart pumps, Bellwether jumped at the chance.
