Passive House Design and consulting

ZeroEnergy Design (ZED) has been targeting Passive House performance for nearly a decade. Our Principals attended one of the first courses in the U.S. for training Certified Passive House Consultants.

We are proud to share that Passive House alignment is the norm at ZED for both design and consulting projects.

Meet Our Certified Passive House Consultants


Passive House Design is Our Specialty

At ZED, our forte lies in creating healthy, comfortable, and sustainable passive homes and buildings. In addition to making Passive House alignment the norm, we also use Passive House Planning Package (PHPP) and WUFI Passive as the energy modeling tools for our design projects.

Passive House principles are integral to our architectural design process. Building diagnostics and commissioning, including blower door testing at key stages in the construction process, a duct blaster for HVAC duct leakage testing, and energy monitoring equipment to track actual performance, are standard procedures for ZED’s Architecture Practice.

Passive House Consulting for Other Professionals

ZED’s Passive House Consulting Practice has been the Certified Passive House Consultant, Mechanical Designer, and Building Enclosure Consultant on many landmark projects. View our Consulting Relationships for a list of industry professionals we’ve had the privilege of working with over the years.

Passive House Certification (Optional)

Many clients opt out of certification and choose to proceed in general alignment with the Passive House standard. High performance is always the goal regardless of certification.

When selecting a particular standard to follow, ZED brings experience with both certifying entities. ZED has facilitated multiple certifications under both the international Passive House Institute (PHI) with their Passive House standard and the Passive House Institute US (PHIUS) with their PHIUS+ standard. We offer energy modeling using either the Passive House Planning Package (PHPP) or WUFI Passive as appropriate.  

Other Certifications (Optional)

ZED also offers the experience of certifications that complement the Passive House Standard, such as the simple REVEAL Label, the more detailed Green Communities Criteria, and the challenging Zero Energy Certification from the International Living Future Institute (creators of the Living Building Challenge).
