This document discusses several ASHRAE standards related to building energy efficiency, including Standard 90.1, Standard 90.2, the Green Building Standard, Standard 189.1, and building energy labels. Standard 90.1 provides minimum energy efficiency requirements for commercial buildings, while Standard 90.2 does the same for residential buildings. The Green Building Standard and Standard 189.1 establish benchmarks for sustainable green buildings. Building energy labels provide information on a building's energy use and performance to help differentiate buildings.

Buildings

2. Today’s building designs
mortgage our energy
future.

3. Why Are Buildings So
Important?
• World total energy
consumption is expected 40% of U.S. Primary Energy Consumption
to increase as high as 50
percent in less than a
decade.
• Buildings are responsible
for 38% of total energy
use – that figure
increases to up to 70% in Source: 2007 Buildings Energy Data Book. Tables 1.1.3, 1.2.3, 1.3.3
some countries.

faster than any other sector.

5. Building Energy Efficiency
“…is the single most
important opportunity
for reducing
greenhouse gas
emissions”
“…is the “fastest-growing
(2007-2008 ASHRAE President Kent Peterson)
success story of the
last 50 years”
(American Council for an Energy Efficient Economy)

6. What is ASHRAE
Doing to Help

7. Standard 90.1
• Standard 90.1-2010 was
published last Fall
• Celebrating 35th
anniversary of publication
of Standard 90.1
• Developed in response to
U.S. energy crisis of
1970s
• www.ashrae.org/90.1histo
ry

8. Standard 90.1
• 2007 standard is the
reference standard for the
International Energy
Conservation Code
• Adopted by National Fire
Protection Association
• Adopted by many
countries around the
globe

9. Standard 90.1
• Provides minimum requirements for the energy-
efficient design of buildings except low-rise
residential buildings
• Covers
– New buildings and their systems
– Additions
– alterations

10. Standard 90.1 Sections
• Section 1 – purpose
• Section 2 – scope
• Section 3 – definitions, abbreviations and acronyms
• Section 4 – administration and enforcement
• Section 5 – building envelope
• Section 6 – heating, ventilating and air conditioning

11. Standard 90.1 Sections
• Section 7 – service water heating
• Section 8 – power
• Section 9 – lighting
• Section 10 – other equipment
• Section 11 – energy cost budget method
• Section 12 – normative references

12. Standard 90.2
The purpose of this standard is to
provide minimum requirements for the
energy-efficient design of residential
buildings.
12

13. Standard 90.2
– This standard provides minimum
energy-efficiency requirements for
the design and construction of new
residential dwelling units
It covers:
– New residential buildings and their
systems
– Additions
13

14. Green Building Standard
• Published in January
2010
• Serves as benchmark for
sustainable green
buildings – does not
apply to all buildings
• Addresses energy, impact
on the atmosphere,
sustainable sites, water
use, materials and
resources and IEQ
www.ashrae.org/greenstandard

15. What is Standard 189.1?
• ANSI standard developed in model code language
• Provides minimum requirements for high-performance,
green buildings
• Applies to all buildings intended as high performance
except low-rise residential buildings (same as
ASHRAE/IESNA Std 90.1)
• Not a design guide, not a rating system
• Jurisdictional compliance option to the International
Green Construction Code published by the International
Code Council and cooperating sponsors, American
Institute of Architects and ASTM International

16. Standard 189.1
Building Blocks

17. Compliance Paths
Mandatory + Prescriptive Path
(simple option, very few calculations)
Mandatory + Performance Path
(more options, but more effort)

18. Standard 189.1 Topic Areas
SS Sustainable Sites
WE Water Use Efficiency
EE Energy Efficiency
IEQ
Indoor Environmental Quality
Building’s Impact on the Atmosphere, Materials &
MR
Resources
CO
Construction and Operations Plans

19. In a global marketplace,
the objective of the
standards development
process must be a single,
internationally
recognized, technically
valid standard that allows
products to be distributed
for commerce worldwide
with minimal change or
modification.
One Global Standard Accepted by All

20. What’s Your Building EQ?
• In Operation Pilot completed
in June 2010
• 23 buildings from 10
owners/operators
• 17 Provisional Assessors
• Assessments include:
- Building characteristics
- Building Energy Quotient
- IEQ Assessment
• As Designed rating was also
followed in second half of
2010
www.buildingeq.com

21. Building Energy Labels
Provide. . .
• Information on the potential
and measured energy use of
buildings
• Feedback to building owners
and operators on how their
building is performing
• Insight into the value and
potential of investments for
long-term energy costs
• Opportunity to differentiate
buildings in a technically
sound and consistent
manner

22. Advanced Energy Guidance
• Over 250,000 guides in
circulation
– 80 percent US, 8 percent
Canada, 12 percent ROW
• DOE recently approved
AEDG 50% Funding
– First Guide to be Small-Med
Office
