Sec. 6 RCW 19.27A.025 and 1991 c 122 s 3 are each amended to read
as follows:
(1)(a) The minimum state energy code for new nonresidential
buildings shall be the ((Washington state energy code, 1986 edition, as
amended)) 2012 international energy conservation code, published by the
International Code Council, Inc. or as amended in the future. The
state building code council may, by rule adopted pursuant to chapter
34.05 RCW, amend that code's requirements for new nonresidential
buildings provided that:
(((a))) (i) Such amendments increase the energy efficiency of
typical newly constructed nonresidential buildings and maintain and
promote a competitive business climate to build a strong state economy;
and
(((b))) (ii) Any new measures, standards, or requirements adopted
as amendments to the international energy conservation code must be
technically feasible, commercially available, and cost-effective to
building owners and tenants and must, prior to filing the rule-making
order, first be evaluated according to national consensus standards
such as: (A) ASTM E917 practice for measuring life-cycle costs of
buildings and building systems; (B) ASTM E1074 practice for measuring
net benefits and net savings for investments in buildings and building
systems; and (C) ASTM E1121 practice for measuring payback for
investments in buildings and building systems, for the purpose of
assessing the impact of proposed amendments to the code.
(b) The state building code council shall adopt rules consistent
with chapter 19.85 RCW and evaluate impacts resulting from adoption of
the energy code based on the extent of disproportionate impact on small
business and reduce the costs imposed by the rule on small business.
(2) In considering amendments to the state energy code for
nonresidential buildings, the state building code council shall
establish and consult with a technical advisory committee including
representatives of appropriate state agencies, local governments,
general contractors, building owners and managers, design
professionals, utilities, and other interested and affected parties.
(3) Decisions to amend the Washington state energy code for new
nonresidential buildings shall be made prior to December 15th of any
year and shall not take effect before the end of the regular
legislative session in the next year. Any disputed provisions within
an amendment presented to the legislature shall be approved by the
legislature before going into effect. A disputed provision is one
which was adopted by the state building code council with less than a
two-thirds majority vote. Substantial amendments to the code shall be
adopted no more frequently than every three years.
Sec. 7 RCW 19.27A.045 and 1990 c 2 s 5 are each amended to read
as follows:
The state building code council shall maintain the state energy
code for residential structures in a status which is consistent with
the state's interest as set forth in section 1, chapter 2, Laws of
1990. In maintaining the Washington state energy code for residential
structures, beginning in 1996 the council shall review the Washington
state energy code every three years. After January 1, 1996, by rule
adopted pursuant to chapter 34.05 RCW, the council may ((amend any
provisions of)) adopt a new edition of the international energy
conservation code as the Washington state energy code to increase the
energy efficiency of newly constructed residential buildings. The
state building code council shall adopt rules consistent with chapter
19.85 RCW and evaluate impacts resulting from adoption of the energy
code based on the extent of disproportionate impact on small business
and reduce the costs imposed by the rule on small business. Prior to
filing the rule-making order, the Washington state building code
council's proposed rules must first be evaluated according to national
consensus standards such as: (1) ASTM E917 practice for measuring
life-cycle costs of buildings and building systems; (2) ASTM E1074
practice for measuring net benefits and net savings for investments in
buildings and building systems; and (3) ASTM E1121 practice for
measuring payback for investments in buildings and building systems,
for the purpose of assessing the impact of proposed amendments to the
code. Decisions to ((amend)) adopt a new edition of the Washington
state energy code for residential structures shall be made prior to
December 1st of any year and shall not take effect before the end of
the regular legislative session in the next year.
Sec. 8 RCW 19.27A.150 and 2010 c 271 s 306 are each amended to
read as follows:
(1) To the extent that funding is appropriated specifically for the
purposes of this section, the department of commerce shall develop and
implement a strategic plan for enhancing energy efficiency in and
reducing greenhouse gas emissions from homes, buildings, districts, and
neighborhoods. The strategic plan must be used to help direct the
future code increases in RCW 19.27A.020, with targets for new buildings
consistent with RCW 19.27A.160. The strategic plan will identify
barriers to achieving net zero energy use in homes and buildings and
identify how to overcome these barriers in future energy code updates
and through complementary policies.
(2) The department of commerce must complete and release the
strategic plan to the legislature and the council by December 31, 2010,
and update the plan every three years.
(3) The strategic plan must include ((recommendations)) a report to
the council on potential energy code upgrades as provided in RCW
19.27A.020. At a minimum, the strategic plan must:
(a) Consider ((development of aspirational codes separate from the
state energy code that contain economically and technically feasible
optional standards that could achieve higher energy efficiency for
those builders that elected to follow the aspirational codes in lieu of
or in addition to complying with the standards set forth in the state
energy code)) the positive benefits of adopting the international green
construction code, for commercial construction, and the national green
building standard and recognized built-green programs, for residential
construction, as optional codes separate from the state energy code
since those codes contain economically and technically feasible
standards that achieve higher energy efficiency than the state energy
code;
(b) Determine the appropriate methodology to measure achievement of
state energy code targets using the United States environmental
protection agency's target finder program or equivalent methodology;
(c) Address the need for enhanced code training and ((enforcement))
administration as well as industry and community outreach and training;
(d) Include state strategies to support research, demonstration,
and education programs designed to achieve a seventy percent reduction
in annual net energy consumption as specified in RCW 19.27A.160 and
enhance energy efficiency and on-site renewable energy production in
buildings;
(e) Recommend incentives, education, training programs and
certifications, particularly state-approved training or certification
programs, joint apprenticeship programs, or labor-management
partnership programs that train workers for energy-efficiency projects
to ensure proposed programs are designed to increase building
professionals' ability to design, construct, and operate buildings that
will meet the seventy percent reduction in annual net energy
consumption as specified in RCW 19.27A.160;
(f) Address barriers for utilities to serve net zero energy homes
and buildings and policies to overcome those barriers;
(g) Address the limits of a prescriptive code in achieving net zero
energy use homes and buildings and propose a transition to performance-based codes commensurate with RCW 19.27A.025(1)(a)(ii) and 19.27A.045;
(h) Identify financial mechanisms such as tax incentives, rebates,
and innovative financing to motivate energy consumers to take action to
increase energy efficiency and their use of on-site renewable energy.
Such incentives, rebates, or financing options may consider the role of
government programs as well as utility-sponsored programs;
(i) Address the adequacy of education and technical assistance,
including school curricula, technical training, and peer-to-peer
exchanges for professional and trade audiences;
(j) Develop strategies to develop and install district and
neighborhood-wide energy systems that help meet net zero energy use in
homes and buildings;
(k) Identify costs and benefits of energy efficiency measures on
residential and nonresidential construction using national consensus
standards such as: (i) ASTM E917 practice for measuring life-cycle
costs of buildings and building systems; (ii) ASTM E1074 practice for
measuring net benefits and net savings for investments in buildings and
building systems; and (iii) ASTM E1121 practice for measuring payback
for investments in buildings and building systems, for the purpose of
assessing the impact of proposed amendments to the code; and
(l) Investigate methodologies and standards for the measurement of
the amount of embodied energy used in building materials.
(4) The department of commerce and the council shall convene a work
group with the affected parties to inform the initial development of
the strategic plan.
Sec. 9 RCW 19.27A.160 and 2009 c 423 s 5 are each amended to read
as follows:
(1) Except as provided in subsection (2) of this section,
residential and nonresidential construction permitted under the 2031
state energy code must achieve a seventy percent reduction in annual
net energy consumption, using the adopted 2006 Washington state energy
code as a baseline.
(2) The council shall adopt state energy codes from 2013 through
2031 that incrementally move towards achieving the seventy percent
reduction in annual net energy consumption as specified in subsection
(1) of this section. The council shall report its progress by December
31, 2012, and every three years thereafter. If the council determines
that economic, technological, or process factors would significantly
impede adoption of or compliance with this subsection, the council may
defer the implementation of the proposed energy code update and shall
report its findings to the legislature by December 31st of the year
prior to the year in which those codes would otherwise be enacted. In
order to arrive at a determination, the council shall use national
consensus standards such as: (a) ASTM E917 practice for measuring
life-cycle costs of buildings and building systems; (b) ASTM E1074
practice for measuring net benefits and net savings for investments in
buildings and building systems; and (c) ASTM E1121 practice for
measuring payback for investments in buildings and building systems,
for the purpose of assessing the impact of complying with this section.
