Agenda…
• Why ASHRAE 189.1-2011 is embedded in
IgCC-2012 as an implementable option within
IgCC
• A summary of what ASHRAE 189.1-2011
tackles
• How ASHRAE 189.1-2011 differs from
ASHRAE 90.1-2010
• How ASHRAE 189.1-2011 ‘can’ lead to LEED
certification
ASHRAE 189.1 and IgCC
•
Jurisdictions are used to having a model code as a basis for adopting
legislation to regulate building construction.
•
As green construction has become more mainstream in the U.S., the time is
now ripe to offer a model code guiding green construction.
•
The agreement between ASHRAE and ICC means that 189.1 fits within the
framework of the IgCC as an option for compliance.
"ASHRAE felt the agreement with ICC was of significant importance to
the industry so there's not two sets of competing green building
standards,"
-- Gordon Holness, ASHRAE's 2009-2010 President
•
Because both standards cover essentially the same areas of building with
approximately the same rigor, jurisdictions (and possibly building owners, in
some cases) will have the option to use either IgCC or 189.1.
•
Because ICC is the most recognized new construction code-writing body, and
with more than 22,000 jurisdictions in all 50 states using ICC codes, the
agreement gives 189.1 the possibility of much wider adoption than if
jurisdictions would have considered adopting 189.1 by itself.
ANSI/ASHRAE/USGBC/IES STANDARD 189.1-2011
Standard for The Design of High-Performance Green Buildings
Except Low-Rise Residential Buildings
A Jurisdictional Compliance Option of the IgCC
• Developed by collaborative effort between the American
Society of Heating, Refrigeration and Air-Conditioning
Engineers (ASHRAE), the Illuminating Engineering
Society (IES) and the United States Green Building
Council (USGBC)
• Establishes mandatory criteria in all topic areas
• Remedies the issue of rating systems containing
few mandatory provisions but still calling the output
a “green building”
• First “code-intended” written Standard for commercial
green buildings in the US
• Covers similar topics as green rating systems
• Provide energy reduction over the requirements of
ASHRAE 90.1 AND reduces negative environmental
impacts through high-performance building design,
construction, and operations practices
Mandatory, Enforceable…
x.1 General. This subsection includes a statement of scope
and addresses other broad issues.
x.2 Compliance Paths. This subsection indicates the
compliance options for each section.
x.3 Mandatory Provisions. This subsection contains the
criteria that must be complied with by all projects (i.e., the
criteria that cannot be traded off).
x.4 Prescriptive Option. This subsection contains additional
criteria specified in a manner that provides a simple way to
show compliance that involves little or no calculations.
x.5 Performance Option. This subsection contains an
alternative way to show compliance that is typically more
complex then the prescriptive option.
Does ‘189’ mean anything?
189 is the…
•
…number of episodes of the TV show ‘Different Strokes’ from
1978-1985.
•
…height (in feet) of Cinderella Castle at The Magic Kingdom.
•
…rank of the song ‘Stayin Alive’ on Rolling Stone’s list of “500
Greatest Songs of All Time”.
•
…maximum seating capacity of a Boeing 727-300 jetliner.

•
The average commercial building EUI (including receptacle and
process loads) could be 70.7 kBtu/ft2·yr if all buildings were
rebuilt to 90.1-2004 standards.
•
By applying a comprehensive package of technologies and
practices, termed “Max Tech” in the report, the EUI could be
further reduced to as little as 40.3 kBtu/ft2·yr.
•
However, if PV was added and the excess generated electricity
could be freely put into the grid, the EUI could be reduced to
12.2 kBtu/ft2·yr.
