Why should we care about material choices when designing affordable housing? During this presentation, Catherine Murphy, Senior Research Associate at Parsons Healthy Materials Lab, and Shelby O’Neil, Senior Program Officer at Enterprise Green Community Partners, will discuss the toxins most commonly found in the indoor environment and how architects, designers, and builders can reduce exposure for vulnerable communities. These experts will review some of the challenges of addressing indoor air quality, as well as what resources to utilize when specifying healthy materials for affordable housing. The session will also provide an overview of the Materials section within the 2020 Enterprise Green Communities Criteria Checklist and explain the NYC Overlay for new construction and renovation projects.
