Case Study
PDF icon College of Marin solar pool heating case study.pdf

In an effort to attain LEED Gold certification, the College of Marin in Kentfield, California recently incorporated solar water heating into a major renovation of its Diamond Physical Education Center. SunWater Solar installed 89 Heliodyne GOBI 410 collectors which will provide warm water for two major public swimming pools. The two pools hold a total of 295,000 gallons of water.

SunWater Solar, located in Richmond, California, designed the project, which consists of a 65-collector system for the lap pool and a 24-collector system for the smaller dive pool. The closed-loop collector system is tied to a heat exchanger that transfers the heat to the pool water. The installation also includes a Web-based monitoring system that tracks the energy produced.

The solar water heated pools complement other energy saving renovations at the Diamond Physical Education Center, including a PV array, new lighting, and a more efficient air heating and cooling system. The new solar water heating system is among the largest in California.
