Innovating Green: How Perkins&Will’s Research Shapes Healthier, Lower-Carbon Buildings

Discover Perkins&Will’s groundbreaking initiatives, including The Switch List and Embodied Carbon Benchmarking Report, which promote healthier materials and reduce environmental impact in design projects.

Key Highlights

  • Perkins&Will invests in research to explore how space, materials, and design influence health, well-being, and environmental impact.
  • The Switch List provides alternatives to harmful construction products, making sustainable choices more accessible for clients and manufacturers.
  • The Embodied Carbon Benchmarking Report offers industry-specific insights to help reduce carbon footprints in building design and construction.
  • Leadership in design combines human understanding with innovative research to create healthier, more sustainable workplaces.

“Lead with integrity, listen with empathy, take action with urgency,” shares Global Workplace Practice Leader, Perkins&Will, John Sadlon. And when more information is needed, don't wait for other firms to find the answers. 

That drive and tenacity in design is supported by Perkins&Will’s dedication to research. The firm invests in various research initiatives. Some of their most recent projects include exploring how space supports diverse ways of working, how materials affect indoor air quality, and how design choices influence energy and carbon over time. 

Beyond seeking answers to some of most pressing questions in design, Perkins&Will readily shares their results. They recently published The Switch List, a targeted list of products and materials that their architects will no longer specify based upon their reported negative impacts on human and environmental health.

“Perkins&Will’s ground-breaking documentation of The Switch List includes a compilation of alternatives to construction products that are linked to health and environmental concerns,” says Sadlon. “For project partners, it makes healthier, lower-carbon material selection more accessible. For product manufacturers, it provides clarity around material expectations and opportunities to develop higher-performing solutions.”

Notable Switch List takeaways include:

  • Products cannot use weathering steel alloys.
  • Composite or engineered wood products cannot contain added formaldehyde.
  • Thermal or acoustical insulation products must be low-emitting and not contain halogenated flame retardants or added formaldehyde.
  • Wallcoverings, upholstery, window coverings, windows, landscape piping or exterior cladding must not contain polyvinyl chloride (PVC) or chlorinated polymers.
  • Metals—including plumbing fixtures, hardware and furnishings—must not be chrome-plated.
  • Lighting cannot be fluorescent.

Perkins&Will has also recently published their Embodied Carbon Benchmarking Report, which was designed to help professionals assess the carbon intensity of their designs with greater accuracy and make more sustainable choices. The report took two years to complete and analyzed 89 projects across 14 building types and multiple climate zones.

“The report equips both our teams and the broader industry with clear, actionable insights to reduce carbon from design through construction,” says Sadlon.
