Healthy materials

Creating a building with a focus on wellness and non-toxic materials.

For decades, we’ve explored how to design the healthiest interior environments. From stories of Google’s founders walking around our early buildings measuring indoor air quality with handheld particle counters, to vetting thousands of products over the years to ensure we weren’t introducing unnecessary toxics to our retrofitted interiors, we have long been focused on creating healthy workspaces. We’re proud that Gradient Canopy is one of the largest projects ever to achieve the International Living Future Institute (ILFI) Living Building Challenge (LBC) Materials Petal certification, which aims to help create a materials economy that is non-toxic, ecologically restorative and transparent.

We prioritized materials that are healthy for people and the environment within Gradient Canopy and the Google Visitor Experience. Every material installed in the building has been reviewed with the manufacturer to ensure it is free of LBC’s Red List ingredients, which represent worst-in-class chemicals that negatively impact human and environmental health. In total, more than 8,000 products were reviewed at Gradient Canopy, working with manufacturers participating in our effort to drive transparency in the building industry.

Our approach to healthy materials at Gradient Canopy extends far beyond the interior spaces and the Googlers who work inside day-to-day. By looking at materials inside and outside the building, including the six public artworks installed around the building’s exterior, we set out to prioritize the health of communities along the supply chain and the entire lifecycle of our building products. That means materials — from things you can see and touch, such as carpet and walls, to those less readily apparent, like window coatings and the building’s insulation — were carefully vetted with their manufacturers to ensure health was a driving factor in its selection.

And it’s not just about this building and the materials used here. In an effort to drive change in the materials industry, the Gradient Canopy team encouraged manufacturers to incorporate Declare labels in their product lines, particularly in industries and product categories where material transparency was largely uncommon. These provide clear, informative “nutrition labels” for building products that are free of LBC Red List chemicals and sourced responsibly. For example, many of the wood doors and frames used in the project obtained a Declare label, which these products did not have at the beginning of the project.

Ultimately, reaching the healthy materials goals at Gradient Canopy meant acknowledging that we are part of a much broader global community of manufacturing and resources. The rigorous LBC materials standards necessitated engaging the entire project team to align on goals and remain open to adapting their traditional processes and methods to nontraditional solutions. Building relationships between designers, manufacturers, subcontractors, tradespeople and construction workers helped the entire team feel comfortable being transparent on their means and methods, and open to learning from one another. Now, as these team members move on to new projects throughout the region and nation, they leave with a robust skillset on vetting and designing with healthy materials to offer for future construction.
