Model National Energy Code for Buildings 1997

• Referenced in the OBC

• Not used by other provinces

• Used by incentive programs and

LEED

• Requirements changed by province

and fuel source

Architecture 2030 Challenge

• Design new buildings to be 60% more

energy efficient than the provincial average

for that building type

• 60% in 2010

• 70% in 2015

• 80% in 2020

• 90% in 2025

• Carbon-neutral in 2030 (using no fossil fuel

GHG emitting energy to operate).
