Stone Ridge Passive House Tour

Please join us for an “open walls” construction phase tour of two residential Passive House projects created by North River Design Build at the former Basten Farm in Stone Ridge, NY. These houses are iterations of North River’s “FlexHouse III” Passive House design concept, featuring flexible living spaces and long-term planning to facilitate adaptive configuration of the homes as living requirements change. Intended to function as a pattern book of Net Zero Energy and Passive House designs, North River’s FlexHouse series offers economical solutions and proven construction practices to homeowners seeking exemplary energy efficiency and innovative, adaptable homes.

The tour will feature guided walks through the sites and houses, with presentations by the design and build teams highlighting the design, technical, energy performance and construction considerations of these projects, which are on track to be the first two homes certified under the Phius Prescriptive Path. A brief session at the end of the tour will introduce visitors to the mission and current activities of the Phius Alliance Hudson Valley Chapter.

In addition to, and as part of, their Phius certification, these projects qualify at the highest level of NYSERDA’s Low-rise Residential New Construction Program, which provides funding incentives to developers of high-performance residential design.
