Our Crew/Technicians

Eco Performance Builders currently has 7 technicians in the field.  They all independently study building science and put their learning to use daily.  Home Performance is an exciting field to work in and it shows with the enthusiasm from all of our workers.  We work in the worst environments in houses (the attic and the crawlspace) and they come out smiling, and sometimes, singing!  It sounds crazy but it is true.

Eco Performance Buiders is interested in building science and making homes better. We are continually testing and monitoring our systems, doing reserach, taking classes on better ways to build, and discussing advancements in what we do with other contractors in order to do the best work possible. In 2006 we went through the Build it Green training and became Certified Green Builders. After completing the certification we became Build it Green, Green Point Raters. Since then they joined the California Building Performance Contractors Association (CBPCA) and went through their Green Home Energy Upgrades nine day course and became Home Performance with Energy Star and BPI certified.  Every semester we try to send every employee to at least one day of training at places like the PG&E training center or other places that offer Home Performance, insulation, or HVAC training.  We also keep a book lending library in our office for our crew to take advantage of.

We continually apply our  knowledge in the field and continue to learn more about new technologies and better home performance applications.
