Healthy Home Remodel – Los Altos
“HBS helped to bring everyone (designers, contractor, and homeowners) around the
table to collectively figure out where to go with the green remodel. Each person on the
project brought a critical, unique expertise, plus walked away learning something new.
The collaboration on the healthy material reviews was especially productive. Hopefully,
this model of collaboration will inspire others to remodel or build with the healthiest
Healthy Home Remodel – Summary
This project involved a whole healthy home remodel. HBS was brought on board for general
green building consulting and preparation for GreenPoint Rated (GPR) certification. The
biggest goal for the remodel was good indoor air quality, so points from this category of
the GPR checklist received the greatest attention.
Healthy Home Remodel Green Building – Process
HBS lead charettes, or team meetings, with the designers, contractor, and homeowners. Several team members already had some experience with and/or certification from Build It Green. Most of these professionals had many years of experience in their respective fields. The purpose of the meetings was to review the GreenPoint Rated checklists and identify target points. An important result was the determination of realistic and affordable measures. Additionally, we discussed general green building strategies, along with the Healthy Home Standard (HHS) checklists. It was decided to pursue some suggestions, but not enough to qualify for HHS certification. More emphasis was placed on work toward application for a GreenPoint Rated Whole House Remodel certification.
Throughout the project, HBS conducted healthy building material reviews and collaborated with the contractor, designer, and homeowners. Beyond tracking GPR requirements, resources such as the Living Building Challenge Red List and Perkins+Will Precautionary List were considered. HBS translated MSDS reviews into easy-tonunderstand terms, and even contacted manufacturers for more information when needed. A large spreadsheet, the “materials matrix”, was updated and maintained throughout the construction process. Of greatest value was the cooperation between HBS and the contractor, the balance of information and experience with product content and performance. For the homeowners, it was valuable to hear from the experts, ask questions, and be a part of the process.
