What our learners think

"A good level and spread of information, and the feedback from the lecturers has given me confidence to support others in Passivhaus work."

David Price

"The course have given me further confidence particularly in managing Retrofit projects and the importance of understanding building physics. Our next project is an EnerPHit which I feel much better prepared for and looking forward to it starting!"

Nikki Lambert

"A great refresher on building physics. I enjoyed applying this to the in depth case study and detailing discussions on risks, benefits, buildability and sequencing whilst hearing about others' experiences and creative solutions."
