Presentation Title: Geothermal Preconditioning for High-Performance Ventilation

Description: Geothermal preconditioning, a standard in European construction, is now gaining traction in North America. As airtight construction moves toward Passive House standards, balanced, filtered, and continuous mechanical ventilation plays a crucial role in improving air quality, reducing energy use, and enhancing occupant comfort.

Join 475.Supply to explore the Brink ERV/HRV System, the most efficient system in North America (certified by the Passive House Institute), and the newly available GHT geothermal preconditioning unit which an innovative geothermal heat exchanger that warms incoming supply air in winter and cools it in summer, ensuring optimal ventilation efficiency and resilience. By leveraging ground temperature for preconditioning and heat recovery, Brink and GHT reduce reliance on mechanical heating and cooling—creating a more resilient, energy-efficient system.

Arturs and Ivars Gredzens of GHT, along with 475's Brink specialist Gabrielle O'Grady, will be giving presentations on how these two technologies work together throughout March. RSVP links can be found below.
