About the event
Building a Passivhaus is never easy. Add six neighbours, 
a compact site, narrow south frontage, an elevated and exposed location, conservation area planning constraints, arboriculture, ecological, and archaeological restrictions into the mix, and you get a flavour of the challenges overcome for CaSA Architects’ recently completed Certified Passivhaus in Marshfield.
Speakers from CaSA Architects will guide visitors around the finished house and present the design process from concept through to realisation on site, with focus on the planning challenges, technical design, Passivhaus challenges and lessons learnt.
They will outline the predicted thermal performance using PHPP compared to actual performance, and the client will be on hand to talk and answer questions about their experience of living in a Passivhaus.
Light refreshments will be provided.
