The 24th St. Passive House Project aims to build sustainability from greenhouse to green houses by implementing buildings based on global leading performance targets like Passive House. The project focuses on energy efficiency and high performance building envelopes to minimize energy losses and maximize gains, with an integrated design approach and performance-based targets to create highly insulated, airtight, and thermally optimized buildings.

“A rigorous, voluntary building energy standard
focusing on highest energy efficiency and quality of life
at low operating cost.”
The Passive House Standard is the most rigorous building energy standard in the world. Consultants, projects or building components that have
obtained the right to carry the logo have committed themselves to design excellence and the Passive House energy performance criteria.
