What is Passive House?

Passive House is an international construction standard maintained and continuously developed by the International Passive House Institute (PHI). Residential, commercial, industrial, and institutional buildings constructed to these guidelines are characterized by significantly increased comfort and health for the occupants, extremely low energy consumption, durable construction quality, and knowledgable project teams at the forefront of the construction industry.

What is the CPHT professional certification?

The CPHT certification allows members of the construction industry to engage and participate in the integrative and interdisciplinary approach necessary for better building. While much improvement can be made in the design and calculation phases of a project, the implementation of Passive House principles on site is absolutely fundamental to the success of a quality build.

What’s the difference between CPHT, CPHD, and CPHC accreditations?

The international Passive House Institute AND the Passive House Institute U.S. both offer training to Designers (CPHD), Consultants (CPHC), and Tradespeople (CPHT). Some of the language can be overlapping and a tad confusing at times, but it’s getting more clear as we gain momentum. At this time, Emu only offers Tradesperson training and exams for the international Passive House Institute’s CPHTradesperson program. However, much of our curriculum can also be applied to other advanced builder training programs. We believe professional accreditations offer you a way to protect your knowledge, but there are many paths to get there.  If you know of an opportunity where our curriculum could be useful in helping you attain a different accreditation, please let us know!

Why become a Passive House Tradesperson?

In 2009, I was at a conference and learned about Passive House; I felt like a teenage boy that just noticed girls for the first time – “Oh my god. You are amazing – how did I not see you before?” — Darren Macri

“The targeted transfer of specific Passive House expertise will provide the basis for a high standard of quality on site. This will ultimately benefit all those involved in construction, including the client, the planner/architect, the manufacturers of products and the tradesmen themselves.”

“There are a lot of things that are different about a passive house. The ventilation systems, the wall sections, the window install, but really, those are all details that you just build as designed. The biggest adjustment for my team and my subs was the air barrier. The air barrier never goes on vacation. We have to own that obsession in our hearts during every step of the process.”
