Simplifying Passive House Multifamily Certification

Tomás O'Leary, Managing Director of Mosart

Passive House certification is essential to ensuring that projects meet exacting standards. Put simply, if a project is not certified, then it's not Passive House. However, the certification process, especially for teams unfamiliar with it, can often seem cumbersome and unwieldy. Tomás O'Leary is a Co-Founder of Mosart, an international firm delivering large-scale PHI certified projects across the EU and US. Drawing on two decades of hands-on experience, this presentation will map out a streamlined path to make the Passive House certification process as painless as possible. The session will outline practical strategies for project teams to ensure the process runs smoothly. It will also touch on the PHI “Classic” vs. “Low Energy Building” standards, equipping teams to bring projects through certification efficiently.
