Last year, a student team from Syracuse University, SUNY Environmental Science and Forestry, and Onondaga Community College competed in and won the first annual U.S. Department of Energy Challenge Home Student Design Competition. The Montage, our submission, represented a healthy, resilient, regionally appropriate, and zero-energy-designed home for local families. An important component of our innovative design was the HVAC system, which incorporated 475 High Performance Building Supply’s Lunos e² for ventilation with heat recovery.

When weighing cost, performance, and compatibility in the team’s decision-matrix, multiple HRV systems took a back seat to the Lunos’ affordability, user-friendliness, efficiency, and decentralized nature. This unit eliminated the need for an expensive duct system, allowing for more things than energy to be saved. Thanks to 475’s expertise and guidance, when presented at the national competition, the Lunos stood firm in a “shark tank” of judges and helped bring the team an additional award for Best Design Solution Integration. It’s truly an exciting whole house ventilation solution.

The Montage and Lunos have been well received at multiple speaking engagements around the country, especially at CNY’s annual Green Building Conference where it will once again be a relevant topic of discussion March 11-13th in Syracuse, NY. As leader of The Montage design team, I will be sharing my findings on the Lunos system, including the Lunos eGO - which I recently utilized in a tiny house project. I will be sharing this year’s stage with big ideas from Sam Rashkin (Chief Architect, DOE Building Technologies Office) and Kevin Stack (CEO at Northeast Natural Homes, Inc.) in a pre-conference session titled, Zero Energy Ready Home Training: Is the Housing Market Ready for Zero Energy Ready Homes? As well as in a kick-off speech from Rick Fedrizzi (CEO of the USGBC and GBCI) called, 360 Performance: From Design to Day-to-Day.
