National Energy Code for Buildings

  1. 1. • National Energy Code for Buildings 2011 • What is it? • How will it effect you? • What else is around the corner? • Building Energy LabelingAgenda • Energy Intensity Metrics • NECB 2015
  2. 2. National Energy Codefor Buildings 2011 • Update to the Model National Energy Code for Buildings 1997 (MNECB) • ~27% efficiency improvement
  3. 3. Model National EnergyCode 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
  4. 4. National Energy Codefor Buildings 2011 • NECB requirements defined by Heating Degree Days (HDD) • Energy source doesn’t change requirements • National Building Code referenced for weather data
  5. 5. National Energy Codefor Buildings 2011 • Contains requirements for: • Building Envelope • HVAC • Domestic hot water • Lighting • electrical power systems and motors • Excludes plug loads
  6. 6. National Energy Code for Buildings 2011NECB Parts Compliance Options3. Envelope • Prescriptive or trade-off4. Lighting requirements in Parts 3 to 75. HVAC Or6. DHW • Performance requirements7. Power and Motors in Part 88. Performance Path

  8. 8. NECB Prescriptive RequirementsBe careful with Climate Zones! Zone 5 Zone 6 Location Toronto Vaughan Mississauga Markham Belleville Kingston Window Usi 2.2 (0.39) 2.2 (0.39) (U-value) Walls (above 0.278 (R-20) 0.247 (R-23) grade) Walls (below 0.3.79 (R-15) 0.284 (R-20) grade)
  9. 9. National Energy Codefor Buildings 2011• Maximum Prescriptive Glazing Ratios • 40% Vancouver and Toronto • 36% Ottawa • 33% Sudbury and Edmonton
  10. 10. National Energy Codefor Buildings 2011 • Lots of other requirements including: • Heat recovery on many systems • Increased equipment efficiencies • Lighting controls
  11. 11. • NECB Coming to BC October 22? • NECB in OBC 2012???

  18. 18. 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).
