What people are saying
Hear what our past students have said about the course.
Taking the Certified Passive House Designer course was a highly valuable experience. It provided a solid foundation in passive design principles and gave me the tools to approach energy-efficient building with much greater confidence. One of the key benefits was the clarity it brought to complex topics like thermal bridging and airtightness. The course helped me identify areas for further development. Overall, it’s been a major step forward in my professional growth and has inspired me to pursue more advanced passive house work.

As a new sustainability consultant, this course has given me more knowledge and confidence! Having completed my PhD in low energy buildings in Ireland, it's been interesting to see how PHPP is filled out and completed.
Sustainability Consultant
Specific benefits gained is that I brushed up on some core building physics principles as well as a new-found appreciation of the energy and comfort benefits that are possible when implementing a well informed and holistic design approach coupled with quality construction execution as prescribed by Passive House. A challenge overcame is my understanding of thermal bridges - this is a subject that I have not come across in my career before and the course provided a good explanation of what they are and the foundation principles on how to calculate them.

Light bulb moment doing this course. Wish I had done it 10 years ago. Its well paced, easy to follow and good balance of text, videos and diagrams to explain concepts. Very pleased!
