Lyle Scott NECB 2011 prescriptive requirements and compliance options as well as a review of provincial and U.S. energy code adoption

2. • National Energy Code for Buildings 2011
• What is it?
• How will it effect you?
• What else is around the corner?
• Building Energy Labeling
Agenda
• Energy Intensity Metrics
• NECB 2015

3. National Energy Code
for Buildings 2011
• Update to the Model National
Energy Code for Buildings 1997
(MNECB)
• ~27% efficiency improvement

4. 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

5. National Energy Code
for Buildings 2011
• NECB requirements
defined by Heating
Degree Days (HDD)
• Energy source doesn’t
change requirements
• National Building Code
referenced for weather
data

6. National Energy Code
for Buildings 2011
• Contains requirements for:
• Building Envelope
• HVAC
• Domestic hot water
• Lighting
• electrical power systems and motors
• Excludes plug loads

19. 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).
