About the visit

Join Green Register members Greenheart Sustainable Construction for a practical look at the realities of air-tightness, cold bridging, MVHR and timber frame. Greenheart will give an overview of the project and why some aesthetic/budget and design decisions meant that Passivhaus certification was not cost effective.
