Do Energy Codes Drive Us Towards
Better Buildings?

2. Context Matters
Toronto, August 2003

3. Early Designs Built with:
• Manufactured materials
• Transported from greater distances
Basic natural ventilation principles are
still used:
• Narrow footprints
• Operable windows
Begin to rely more on:
• Mechanical Systems
• Elevators
• Electric lighting

4. Sick Building Syndrome
• world oil shortage – 1970
• Shift towards saving energy

5. LET IT BREATH!
Y2K & Beyond:
Operable Windows
Natural Ventilation
Shallow Floor Plates

North American Building Energy Code Development, December 2011

7. ENERGY CODES AND INDUSTRY
TRENDS: ARE THEY LINKED??

8. Current Standards
Ontario Building Code
• SB-10 Supplement (2012) – ASHRAE 90.1 (2010) & ASHRAE 189
National Building Code of Canada
• National Energy Code for Buildings 2011
Toronto Green Building Standard
• ASHRAE 90.1 – 2010 / MNECB
LEED Canada 2009
• ASHRAE 90.1 – 2007

• New Building Institute Core Performance Guide
• EnergyStar Commercial - Under review
• CEE (Center for Energy and Environment)
• FEMP (Federal Energy Management Program) – Under review

10. Trends – International Perspective

11. Trends – North America
US DOE Section 201:
In 2014 – 2015 ASHRAE 90.1 to be 50%
below the baseline (ASHRAE 90.1-
2004/IECC 2006)
Every three years afterwards to 2030,
American Energy Code Trends an
additional 5% reduction each edition.

12. Trends - ASHRAE 90.1

Board of Director’s Goals

13. Canadian Perspective
Provinces with enforceable building energy codes today:
• Ontario – OBC / SB-10 Standard (ASHRAE 90.1-2010)
• British Columbia (ASHRAE 90.1-2004)
No other Province in Canada as of today has an enforceable Commercial Building Energy Consumption Code
adopted in their Provincial Building Codes.
Quebec is very close to adopting an Energy Code
Nova Scotia is studying the adoption of an Energy Code
Manitoba and Alberta are moving towards a commercial
building Energy Code

14. National Energy Code for Buildings
• NECB 2011 was evaluated by a
consultant and is currently showing a
27% improvement over MNECB-1997
• On par with ASHRAE 90.1-2010 with
some differences
• To be upgraded every 5 years with the
intent of aligning with Provincial
Building Code Update years

15. Accountability

16. HOW DO YOU DRIVE THE INDUSTRY
TOWARDS A CULTURE OF
ACCOUNTABILITY??

• City of Vancouver: Energy Use Intensity (EUI) (kWh/m2/Year)
in energy bylaw for 2016

19. Energy Labeling of Buildings
Energy Labeling of Building Energy

required in Seattle & multiple US Cities

20. Measurement & Verification
• Benchmarking Essential
• Building Energy Labeling Compliance
• Energy Use Disclosure
• Net Zero Energy Buildings – looking beyond LEED®
• Living Building Challenge as leading edge standard for
sustainability – beyond energy

21. CAN ENERGY CODES GET HIGH
PERFORMANCE BUILDINGS INTO THE
MAINSTREAM?

22. Yes

26. Six Steps Towards High Performance

CASE STUDIES

28. Understanding

29. Empire State Building |New York |USA
New York Mayor Bloomberg harnessed the
green power of Earth Day to unveil a plan that
would require NYC buildings – responsible for
80% of the city’s emissions – to undergo
regular energy audits and retrofits, as needed,
in order to become more energy efficient.

30. Empire State Building | New York USA
• Chiller plant was retrofitted and downsized
instead of replaced and upsized
• Recommended upgrade or replacement of
major building systems;
• identified seven more economically viable
projects that provided:
– overall 3-year payback
– 38% energy use reduction.
– Reduced cooling load requirements by 33%
(1,600 tons)
– Reduced peak electrical demand by 3.5
megawatts

31. Empire State Building | New York USA
Energy Focused Retrofits
• Radiator Insulation and Steam Trap Savings:
$491,191
• Windows Retrofit: $338,508
• Direct Digital Controls and Demand Control
Ventilation: $858,305
• Chiller Plant Retrofit: $675,714
• Tenant Energy Management: $386,709
• Tenant Daylighting, lighting and plugs: $940,862
• VAV Air Handling Units: $702,507
Total: $4.3 Million savings to date
5% Improvement on guarantee target for 2012

32. Closing Thoughts
…The award winning new project today
will operate at the worst it should ever perform…
in it’s lifetime
Kevin Hydes, 2009

33. Building projects can take anywhere from 3 to 5 years to go through land purchase,
rezoning, and development permit process to turnover.

34. We need to be looking ahead to Future Proof the Energy Performance of our buildings.
