What our trainees say

speech marks

I'd been a CPHC for years, and sat through more consultant-training classes than most (and taught parts of a couple), when I took the Passive House Academy's series. They had a lot to teach me. Whether you are new to Passive House, or already experienced and hungry for more, I expect you will get a lot from this course. PH educational offerings have expanded since I first became involved, speech marksand I am sure there are many great teachers out there, but Tomas is the best I have encountered.
Hayden Robinson Zertifizierte Passivhausdesigner

speech marks I would like to express our sincere gratitude, again, to both you and Michael for the most intense and amazing course we have taken since working in the profession.  You guys did a fantastic job of conveying the material to us in the speech marksmost efficient, clear, and enjoyable manner possible.
In Cho, ChoShields Studio

speech marks Thanks for a really interesting and challenging class.  It's made me remember how much I enjoy being a student.  The architects in study group were commenting on speech markshow this type of information is not covered at all in architecture school except possibly as an elective.

I wanted to thank you again for bringing enthusiasm, encouragement and instruction loaded with accessible lines of reasoning peppered with memorable turns of phrase that were not just entertaining but integral to learning. I have received great feedback about the class so far; everybody is looking forward to the next session.
I wanted to ask a PHA if they/you might be in a position to support phME through a sponsorship or corporate membership.  I have attached a letter about sponsorship and our membership levels are on the website.  As you know these passive house organization are often run on a shoe string, predominantly with a volunteer staff promoting systems, products and practioners of passive house.  In addition, if you feel inspired to write a few words of endorsement of passivhausMAINE it would be wonderful to use them in our promotion.
Thank you, Tomasspeech marks
