This week we welcome Erik Malmstrom and Christian Weeks to discuss a new document on How to Achieve Sustainable Indoor Air Quality: Part 2 A Roadmap to Simultaneously Improving Indoor Air Quality & Meeting Building Decarbonization and Climate Resiliency Goals. This is a multi layered “Clean First” approach to IAQ which they feel is the key to the low-energy, high-IAQ, climate resilient buildings of the future.  Erik Malmstrom is CEO of SafeTraces, a Bay Area-based provider of the only indoor air quality verification that actively measures pathogen risk, via patented aerosol tracing technology, in order to optimize safety and sustainability for enterprise real estate clients. Previously, he held senior roles at the White House, Farmers Business Network, and Cargill, is a co-founder of CrossBoundary - a leading frontier market investment advisor, and is a combat veteran and graduate of U.S. Army Ranger and Airborne Schools. He received his undergraduate degree from the University of Pennsylvania and a joint M.B.A. – M.P.P. from Harvard Business and Kennedy Schools. Christian Weeks is the CEO of enVerid Systems, a leading provider of sustainable indoor air quality (IAQ) solutions. Christian has over a decade of experience in energy efficiency and IAQ. Spurred by the lessons gleaned from the pandemic and the pressing need to reduce carbon emissions and make buildings more resilient, Christian is passionate about helping commercial buildings attain the traditionally conflicting goals of healthy indoor air and energy efficiency. Christian advocates that buildings take a system-level approach to achieving these goals, what he terms Sustainable IAQ. He recently spearheaded a collaboration with other leading IAQ and energy efficiency organizations to detail the Clean First framework, a four-step process for achieving low energy, high-IAQ, climate resilient buildings. The seven collaborators – 75F, Awair, enVerid, GIGA, Oxygen8, Planled and SafeTraces – published in August 2022 a white paper geared for building owners and operators, architects, energy efficiency consultants, mechanical engineers and contractors called “How to Achieve Sustainable IAQ: A Roadmap to Simultaneously Improving IAQ, and Meeting Building Decarbonization and Climate Resiliency Goals.”
