Holliston, MA – Colantonio Inc. announced that six additional staff members have achieved certification as Passive House Builders by the Passive House Institute US (PHIUS): Project Managers Marc Chen, Jacob Robitaille, and Andrew Kantorski, along with Estimators Nick Bean, Brett Szymko, and Lawrence Broderick.
Nearly half of the firm’s project management and estimating staff are now Certified Passive House Builders. Representatives of the firm say Certified Passive House Builders are prepared to address challenges unique to passive building and specific to their region’s particular climate variations, market conditions, and building components.
According to the PHIUS website, the Passive House standard “stands for quality, comfort and energy efficiency.” Passive building principles, which can be applied to all building types from single-family homes to skyscrapers, focus on superinsulation, airtight envelopes, high-performance window installation, site management, and component sourcing. They offer a path to net zero and net positive buildings by minimizing the load that renewables are required to provide.
