Episode 17: Refining the Model

Passive House design and construction is a team sport. It requires effective strategies and cooperation, but also precision in the field and the ability to tweak and recalibrate systems once the building is complete. A robust envelope may be the superpower of Passive House construction, allowing for downsized mechanical systems, electrification, and reduced stress on the energy grid, but these benefits are only achieved if everything works as intended. In this episode, host Zack Semke shares selected clips of conversations from the Reimagine Collective. Featured speakers include Carmel Pratt of ZAZNRG ( https://zaznrg.com/origin-story ) and Passive House New York on post-occupancy data, Ed May of bldgtyp ( https://www.bldgtyp.com/ ) on modeling literacy, Skyler Swinford of Energy Systems Consulting ( https://energysys.co/ ) with Lloyd Alter of Toronto Metropolitan University on refrigerants and water-based distribution, James Peterson of Petersen Engineering ( https://www.petersenengineering.com/o... ) on heat pump water heaters, and Nick Nigro of Leggett McCall ( https://www.lmp.com/ ) on what's next at the innovative and enormous Bunker Hill housing redevelopment project.
