emeraldECO is a one-stop consulting & construction firm focused on retrofitting existing homes and businesses to be fossil fuel & carbon-free structures. We look at the entire envelope of the house and make recommendations to create an all-electric, zero net energy home. emeraldECO also performs Title 24 energy modeling, CALGreen verification, and Green Point rating.

Why We're Green

We are 100% Net Zero. We don't want our children to look at us and ask us why we didn't take action when we knew we were responsible for climate change.


The services we offer are about creating sustainable, fossil fuel-free buildings, so naturally, our office is 100% electric and much of it from recycled waste! -- diane
