2020 40 Under 40: Noah Zallen, PE, 32

Associate Principal, Integral Group, Oakland, Calif.; MS Sustainable Design and Construction, Stanford University

By Chris Vavra and Amara Rozgus May 14, 2020

Specializing in zero net energy buildings, radiant heating and cooling and geothermal and central plants, Zallen has designed energy-efficient HVAC systems for projects ranging from a low-cost ZNE office building with pioneering radiant design to a central plant serving a 1.1-million-square-foot technology campus. Zallen strongly believes that energy-efficient design done right is simple and affordable. He prides himself on the ability to communicate complicated ideas to everyone to foster team coordination and solutions. In college, Zallen heard a statistic that 40% of the energy in the world was spent on heating and cooling buildings. This statistic, combined with his love of nature, inspired him to pursue sustainable engineering. One of Zallen’s biggest strengths is in solving a problem where the answer — and how to get there — is not known, such as answering the question, “How do we accelerate the adoption of radiant heating and cooling?” Zallen joined forces with an industry partner to turn a spreadsheet idea into an application called Radiant Master, which is Integral Group’s first foray into software as a service. Despite all of his focus and hard work Monday through Friday, Zallen knows how to let go of work responsibilities and achieve work-life balance. A true weekend warrior, he can often be found hiking and rock climbing. An experienced and passionate climber, he has completed many 500-feet-plus multipitch climbs and in 2019 he completed his first multipitch in Yosemite National Park, a major personal achievement. He and his wife enjoyed a monthlong honeymoon in South America in early 2020. They got married at a venue Zallen helped design, making the event even more personal.
