New Home Certified Energy Advisor History History: “Certified Energy Advisors” have worked with almost every 1&2 family home since 2009 in Vancouver, well over 3000 homes submitted reports Role was to create an energy model and blower door test(BDT) the home Model and BDT submitted to the city 11

 Pre Building Permit Requirements*  Pre Permit Form  Insulation Verification*  Pre Permit Form  Prior to Final Inspection (no change)  Submit final EnerGuide Report *Orange items are new requirements 12 Expanded CEA Role Requirements

The City will provide a FSR “Bonus” for the thicker walls so interior volume is not sacrificed [This is available to any house with wall R values that exceed R22 effective]. In the RS-1 zone you can build a taller house and a deeper house to account for thicker walls, thicker under slab insulation and thicker attic insulation. 16 Removing Barriers
