Energy Upgrade Your Building

Energy efficiency upgrades to your building are a cost effective way to achieve savings and comfort. 


If you aren't sure where to start, meet with a BayREN Energy Advisor. Energy Advisors are not affiliated or employed by other contractors. Their goal is to help you find the right approach, financing, rebates, and qualified contractors to make your building as energy efficient as possible.

BayREN offers a wide range of commercial programs. 


BayREN's Bay Area Multifamily Building Enhancements program offers cash rebates and no-cost energy consulting for multifamily properties that undertake energy and water upgrades. The program assists in planning energy saving improvements designed to save 15% or more of a building's energy and water usage and provides $750 per unit in rebates to help pay for the upgrade. 

See examples of possible upgrades to commercial buildings in this EPA video - Energy 101: Energy Efficient Commercial Buildings.

The Energy Efficiency Pyramid serves as a general reference for you to explore which upgrades might be most cost effective to save energy in your building. The higher you go up the pyramid, the more expensive and complex the improvement. In other words, start at the bottom and work your way up. See the full article on the pyramid at Green Building Advisor.

Property Assessed Clean Energy (PACE) financing allows property owners to fund energy efficiency, renewable energy, water conservation, and seismic upgrades with little or no up-front costs.
