Bill Ganz

S3 was founded by Bill Ganz in 2019 with a forward-looking vision to transform how businesses approach energy efficiency and indoor air quality (IAQ).

Recognizing the financial and environmental benefits of reducing electric grid demand, Bill focused on optimizing building system performance, particularly HVAC systems, to drive impactful change.

Under his leadership, S3 has evolved into a comprehensive consultancy, delivering solutions that go beyond the legacy approach of addressing only part of the problem.
