ASHRAE Standard 189.1 presented by Rick Hermans of McQuay at the June 14 Chapter meeting of the Illinois Chapter of ASHRAE

1. ANSI/ASHRAE/USGBC/IES Standard 189.1-2009
Green is becoming Official

3. What is “Green”

4. Why is That?
• Being “Green” or “Sustainable” has
become the preeminent feel-good cause
of the last quarter century.
• Who can be against such a combination
of virtue and vagueness; economics and
ecology, simple-mindedness and
soothsaying?
• Greenwashing is RAMPANT!

5. What is “Green”
One problem in defining green or
sustainability is that it has come to
mean so much to so many.

of High Performance Green
Buildings

• Materials and Resources
• Construction and Operation
• Why all the bother?
• Energy Targets

8. What is Standard 189.1-2009?
• An ANSI standard developed in model
code language that provides minimum
requirements for high-performance, green
buildings
• Code and Contractually enforceable
• Sponsor and co-sponsors:
• ASHRAE - American Society of Heating,
Refrigerating and Air Conditioning

for the movement of water to the air from sources such as the soil, canopy interception, and water
bodies. Transpiration accounts for the movement of water within a plant and the subsequent loss
of water as vapor through stomata in its leaves.

• Lower the day-lit plane to 2.5 feet AFF

43. Normative Appendix D: Energy
Performance
• Mandatory provisions are still required
• Variations from the prescriptive provisions
are allowed only if they can be completely
and accurately modeled. E.g. air barrier
• Plug and process loads are required in
both Baseline and Proposed models
• Fan power can be different in the
proposed building

44. Normative Appendix D: Energy
Performance
• Perception is not reality
• “Your results may vary.”
• The performance option is a comparison
of one hypothetical building to another
hypothetical building
• Building additions can be modeled
• The designer can choose to ignore the
existing building

45. Software
• DOE-2
• Various flavors
• BLAST
• EnergyPlus
• eQuest (DOE-2)
• EnergyPro (DOE-2)

46. Energy Targets: the new Paradigm
• Std 90.1 and Std 189.1 use energy use
comparisons
• BeQ Labeling uses comparisons
• EnergyStar uses comparisons
• It is time to look beyond relative metrics
• Targets are absolute numbers (EUI)

47. Energy Targets

48. Energy Targets abound everywhere
• Net Zero Energy – regardless of the
definition is an energy target
• Without some type of specific,
measurable, objective target progress is
slow and ill defined.
• The Commercial Buildings Energy
Consumption Survey shows this clearly
• Market forces alone do not drive
consistently increasing energy efficiency

59. ASHRAE Std 169
Climate Zones Includes Canada and many
International locations

60. What’s Going On at ASHRAE?
• In February of 2010
ASHRAE Technology
Council appointed an
Ad Hoc Committee to
establish a plan for
Energy Targets
• Report submitted
June 2010

61. What’s Going On at ASHRAE?
• Recommendations:
• Conduct a comprehensive education program to
promote a common understanding of EUI
• Develop EUI Targets for Commercial Buildings
(with and without on-site renewables)
• Fulfill the Vision 2020 goal with the AEDG
• Revise the NREL study with new technologies

62. What’s Going On at ASHRAE?
• Status:
• Implementation of the recommendations is
underway
• ASHRAE will consider the Research Work
Statement next month in Montreal to begin
developing the Energy Targets
• Education and Advocacy has begun
• An amendment to the Energy Conservation and
Production Act (42 U.S.C. 6833) has been
submitted in the Senate (May 12th) to develop
definitions of energy use intensity and building
types for use in model codes or in evaluating
the efficiency impacts of the codes

63. Std 189.1 and IGCC
• International Code Council (ICC) main
model code developer in USA
• Reach 22,000 jurisdictions
• developing model High Performance
Bldg code
• Still in development
• ASHRAE has entered into an
arrangement for Std 189.1 to be one of
the compliance paths in IGCC
• Std 189.1 will be packaged with
IGCC when it comes out
• Std 189.1 is available right now
• www.ASHRAE.org

64. Army Adopts Std 189.1
• On Oct. 27, 2010, Katherine Hammack, assistant
secretary of the Army for installations, energy
and the environment (IE&E), issued a policy
memorandum that incorporates
ANSI/ASHRAE/USGBC/IES Standard 189.1-
2009, Standard for the Design of High-
Performance, Green Buildings Except Low-Rise
Residential Buildings.

65. Closing Remarks
• Std 189.1 is an excellent tool to base line
a high performance building
• Std 189.1 energy performance is 30%
higher than Std 90.1
• There are many products and services
available today that will help you
achieve 189.1 prescriptive
requirements
• The Future for energy conscious design
is building energy use performance
metrics
