The full talk is here but the key principals are:
Massing:
Is the thermal envelope really a simple shape?
Fenestration:
Dominates PHPP but use daylight criteria to size windows
Ventilation:
Consider central systems, early design input absolutely crucial
Distribution losses :
Significant impact on primary energy and overheating, standard solutions don’t work
He also sat on the panel at the end of the day discussing scaling up Passivhaus in the UK:
Honesty Be honest regarding bad design decisions. ‘Sharing knowledge means the industry can learn from mistakes rather than repeat them’ says Pete Warm, WARM. This was echoed by Gwyn Jones, Norwich City Council, who says ‘we should learn from each other.’ Constructive feedback will facilitate improvement within the industry as a whole.
