Sustainable Architecture That Works

Overview BIM Passivhaus BIM + Passivhaus BIM 4 Passivhaus Outcomes

BIM “Building Information Modeling (BIM) is the process of generating and managing information about a built asset over its whole life.” Cabinet Office 2012

BIM A quality assurance delivery strategy to provide the right information at the right point in the process

Passivhaus “…the world’s leading standard in energy efficient design” Optimal Comfort (ISO 7730) Minimum Energy

PHPP “simplified models, precise data” Accurate Open Parametric Instant

Passivhaus A quality assurance standard that ensure that the right information is used at the right point in the process to deliver reliable energy performance & comfort.

BIM + Passivhaus Process + Information + Model and test

- Not box ticking - Not sexy graphics - Not on site

Outcomes 2 x 65kW Boilers for a 2200m2 School 25kW peak heat demand = 5x oversized! 90% reduction in gas consumption

Fresh Indoor Air

“We feel that our children are more alert and attentive in lessons due to the amount of daylight in classrooms and the fresh air throughout the school ... learning has been enhanced” Sara Morris, Head Teacher

Conclusion Use BIM to support the Passivhaus design process People design sustainable buildings not software!
