About Us
Eco Performance Builders was started by brothers Scott and Keith O’Hara with the goal of building and retrofitting homes making them more energy efficient, more comfortable, safer and healthier.

Scott earned a Bachelor’s Degree in Business with a Minor in Real Estate and Land Use from Sacramento State University while working as a carpenter. After graduation he worked for a local contractor for two years before receiving his general contractors license. In 1997 he started Scott O’Hara Construction. He has been building and retrofitting homes in the Bay Area for 14 years. He has always taken the green approach to building, even before it was known as “green.” Scott is a licensed ‘B’ General, ‘A’ Engineering and ‘C20′ HVAC contractor. Scott is BPI certified as a building analyst.
Scott manages the office, sales, assessments and initial planning of projects. If you visit our office you will often find his dog Ella, a beautiful Chocolate Lab, in his office keeping him company.

Keith earned a Bachelor’s Degree in Liberal Arts with a Minor in Mathematics from Chico State University while working as a carpenter. After his graduation he joined Scott at Scott O’Hara Construction. Keith specialized in HVAC, carpentry, insulation and obtained his own general contractors license. He is a certified BPI Building Analyst, Envelope Professional, Heating Professional and a HERS rater.
Keith manages the field crews, engineers all of the retrofits and makes sure all homes, and their systems, are commissioned properly.

Sharon Ostreicher is the office manager for Eco Performance Builders. She handles all of the rebate processing, payroll and manages communication between the office and the field. She is the glue that holds it all together. Her easy going attitude and great work ethic make her a great co-worker and manager for our staff.
Eco Performance Builders currently has 8 field technicians in the field. They all independently study building science and put there learning to use in the field. 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 taking classes on better ways to build. 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.
