What our learners think

"I feel much more technically prepared to detail and inspect the next low energy or Passivhaus project that lands on my desk."

Carl Roland

"This intense three-week course strengthened my understanding of energy-efficient building design. I’m looking forward to applying the principles I learned in future projects and gaining more practical experience."

Arushi Gosain

"Building physics occur in our projects whether you understand them or not. This course gives you Jedi levels of understanding."

Seb Laan Lomas
Associate & Passivhaus Designer

"The knowledge gained from this course is now integrated into the design and detailing of all practice projects. We have expanded the practice’s reach, attracting a broader range of clients and project types."
