“Callahan is committed to designing and constructing sustainable and low energy-producing buildings, and having so many team members certified with Passive House makes this goal tangible and attainable on a different level,” said Patrick Callahan, president of Callahan Construction Managers. “We are extremely proud of our team members’ achievements and look forward to leaning on their expertise to make every project environmentally-friendly.”

Buildings that meet the PHIUS+ standard use 40 to 60 percent less energy for space conditioning than typical buildings. Any project that meets the Passive House standard provides superior indoor air quality, resilience during power outages, and an extremely quiet, comfortable indoor environment.

Passive House is a standard for energy efficiency used by the architecture, engineering, and construction industries to construct low energy-usage buildings. Companies like Callahan are increasingly adopting passive house building principles to achieve Net Zero Energy (NZE) for their projects. The total annual energy used by NZE buildings is equivalent to the renewable energy it creates, resulting in net zero energy consumption.
