Alter Consulting Engineers was founded by three passionate engineers who have a history of  collaboration in HVAC and plumbing design for High Performance and Zero Net Energy building design. Alter Consulting Engineers grew out of the desire to make the team’s vast experience in low energy buildings attainable to a wider audience with a focus on the greater San Francisco Bay Area. 

With a combined 30 years’ experience, Alter Consulting Engineers is well-versed to tackle projects of a wide variety of scales and scopes. Together we have experience specializing in the design of Zero Net Energy buildings, as well as LEED and other high performance building rating systems. With a long history of working in the state of California, our team is well-versed in Title 24 and CalGreen requirements. We have comprehensive experience in design drawing creation as well as design-build handoffs, MEP concept development, and master planning. Our team has a special focus in energy modeling, which is extensively used in all parts of the design process to ensure our designs feature optimized efficiency.
