operation year-round) that have
been recognized with a unique test
and rating standard (ANSI/ASHRAE
Standard 127).
CE203 makes changes to the
requirements for air- and watercooled chillers, which is a continuation of the efﬁciency improvements
that were implemented in Standard
90.1-2010 by further improving the efﬁciency requirements.
Improvements also were made to
the requirements to clarify the use
of reference standards for rating and
certiﬁcation. An additional exclusion was added for high temperature heat reclaim chillers from the
equipment efﬁciency requirements
of Table 6.8.1C when the leaving
condenser temperatures are greater
than 115°F (46°C).

Lighting
CE 310/311 updates the lighting
power densities (LPDs) to account
for changes to recommended light
levels as published in the new,
10th edition of the IES's The Lighting
Handbook to match the changes
in Addenda bh and dj to Standard
90.1-2010. Some values have gone
up while others have gone down.
As an average, the changed LPDs
dropped 6%. Four new space types
have been added in response to
user requests: copy/print rooms,
loading docks, interior, and computer rooms. Also in response to
user requests, new space types
for assisted living facilities were
added including corridor, dining
area, lobby, restroom, chapel and
recreation room. In all cases these
modiﬁed LPDs are restricted to
those spaces that are used primarily by the residents.

IECC Proposals
Last year, proposals to the IECC
were submitted by Jan. 3, 2013,
which were heard and discussed
at the IECC Committee Action
Hearings held April 20 to 30, 2013.
Comments on committee action
were submitted by July 15, 2013.
Final action was taken on all proposals and comments at the Public
Comment Hearings held from
Oct. 5 to 10, 2013.

Equipment That Is Federally Mandated
These proposals added current
federally mandated requirements
into the IECC so code ofﬁcials
have the information in one book,
rather than needing to search the
Code of Federal Regulations. These
products will be phased out of the
marketplace to comply with federal
law, but this will prevent the use of
aftermarket and phased out products in permitted construction.
CE240 adds minimum efﬁciencies
for walk-in coolers and freezers that
the Department of Energy deﬁned
as of Jan. 1, 2010. Additional requirements for commercial refrigeration
equipment also have been deﬁned
and approved per 10CFR Part 431
and went into effect on Jan. 1, 2012.
As part of the DOE evaluation, they
have calculated that the standard
changes will result in 1.035 quads
of energy savings over a 30-yearperiod from 2012-42. The economic
analysis shows a scalar (payback) of
1.3 to 3.9.
CE329 adds requirements for
electrical transformers. Under
the Energy Policy Act of 2005, new
national minimum efﬁciency

MARCH 2014

standards went into effect for low
voltage dry-type transformers
manufactured on or after Jan. 1,
2007. According to an analysis performed by DOE in the Federal Register
(Volume 69, No. 145), the changes
would result in an estimated savings
of 4.74 quads of primary energy over
28 years (2007 to 2035). In terms
of cumulative electric site energy
savings, that is roughly equivalent
to 596 billion kWh over 28 years, or
21.3 billion kWh per year.
CE331 adds requirements for
general purpose electrical motors
(Subtype I and II) as deﬁned
in Section 313 of the Energy
Independence and Security Act of
2007 (EISA 2007) and mandates that
the efﬁciency of general purpose
motors (manufactured or imported)
that are rated at 1.0 horsepower and
larger be increased for motors. In
addition, there are new efﬁciency
standards that are required for larger
motors that may be used by commercial/industrial customers (sized
greater than 200 hp [149 kW] and less
than or equal to 500 hp [373 kW]).
Table 1 further summarizes the
results of all proposals of interest
to ASHRAE in addition to the summary above. Thirty-seven of the
proposals submitted by ASHRAE
were accepted (green), ﬁve of the
proposals were disapproved but
a similar proposal was approved
(white/blue respectively), 10 were
disapproved (red), and three were
withdrawn (red).
In future code cycles (starting in
2014), ICC will allow all members to
vote electronically on proposals during their process. For more information, visit http://tinyurl.com/
