I am a Realtor and Certified Green Building Professional with a mission to increase the visibility and number of energy-efficient homes on the Peninsula. Through personal experience, including management of a custom-home builder’s office, I am aware that some homeowners are talked out of going green, because their contractors are not comfortable with it yet.

Mercedes Corbell Design + Architecture has been the architectural firm for a number of green home projects since focusing on sustainable design in 2000. Many of our projects are the renovation and expansion of existing homes and outdoor spaces. Our material and product choices are key to achieving “green goals.”

A recently completed project is the addition of a “granny unit” to an existing Mediterranean style bungalow. Some of the green features were the use of optimal value framing to save on lumber, all FSC-certified framing lumber and plywood, fly ash in the concrete mix, higher levels of insulation than required, and no-VOC paint.

We are certified green building professionals with Build it Green. Mercedes is the co-founder with David Johnson of the Green Remodeling Guild (now part of Build it Green), and the chairperson of the steering committee.
