Register for the next Hudson Valley regional meet up happening Tuesday, September 8, 2026 in Yonkers!

Join us in Cooperstown, NY for a tour of The Grove, a three-building PHIUS pre-certified development.

Join us for a tour of a nearly completed passive house retrofit in Millerton, New York. Originally built in the 1990s, this home has undergone a comprehensive transformation focused on energy performance, durability, comfort, and indoor air quality, all while preserving and enhancing the character of the existing structure (with a few sexy additions along the way).

Join River Architects and Phius Alliance NY for an exclusive behind-the-scenes tour of a Phius-certified passive house project in Gardiner, NY, led by River Architects Principal, James Hartford. This high-performance residence demonstrates how climate-specific building science, environmental responsibility, and architectural design are integrated into a cohesive, site-responsive solution.
