1 AN ACT Relating to strengthening energy codes; amending RCW
2 19.27A.160, 19.27A.015, and 19.27A.020; adding a new section to
3 chapter 19.27A RCW; and creating a new section.
4 BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF WASHINGTON:
5 NEW SECTION. Sec. 1. In order to meet the statewide greenhouse
6 gas emissions limits in RCW 70A.45.020, the state must require
7 construction of increasingly low-emission energy efficient homes and
8 buildings and achieve construction of zero fossil-fuel greenhouse gas
9 emission homes and buildings by 2030. Top categories of clean energy
10 jobs in the buildings sector include: High-efficiency heating,
11 ventilation, and air conditioning; energy efficiency technologies;
12 and renewable heating and cooling. As the fastest growing clean
13 energy industries in our state, work in these areas also supports job
14 creation in other construction trades, which is a critical component
15 of a clean energy economic recovery strategy.
16 Sec. 2. RCW 19.27A.160 and 2009 c 423 s 5 are each amended to
17 read as follows:
18 (1) Except as provided in subsection (2) of this section,
19 residential and nonresidential construction ((permitted under the
20 2031 state energy code)) must achieve ((a seventy percent reduction
p. 1 ESHB 1770
1 in annual net energy consumption, using the adopted 2006 Washington
2 state energy code as a baseline)) the following:
3 (a) A reduction of at least 70 percent in annual net energy
4 consumption under the residential and nonresidential energy codes
5 that are adopted by the council by December 1, 2031, using the
6 adopted 2006 Washington state energy code as a baseline; and
7 (b) New buildings must be net-zero ready, including a reduction
8 of at least 80 percent in annual net energy consumption using the
9 adopted 2006 Washington state energy code as a baseline and must
10 include wiring for electrical raceways and designated space for solar
11 equipment for photovoltaic panel installation under the residential
12 and nonresidential state energy codes that are adopted by the council
13 by December 1, 2034. The state building code council shall further
14 define and include net-zero ready measures in the code adoption
15 process, including exemptions for either construction sites or
16 buildings, or both, that do not have adequate solar exposure to
17 justify the installation of solar ready measures. The 80 percent
18 reduction requirement does not apply to the increased load for
19 electronic vehicle charging.
20 (2) The council shall adopt state energy codes from 2013 through
21 2031 that incrementally move towards achieving the seventy percent
22 reduction in annual net energy consumption requirements as specified
23 in subsection (1) of this section. The council shall report its
24 progress by December 31, 2012, and every three years thereafter. If
25 the council determines that economic, technological, or process
26 factors would significantly impede adoption of or compliance with
27 this subsection, the council may defer the implementation of the
28 proposed energy code update and shall report its findings to the
29 legislature by December 31st of the year prior to the year in which
30 those codes would otherwise be enacted.
31 Sec. 3. RCW 19.27A.015 and 1990 c 2 s 2 are each amended to read
32 as follows:
33 ((Except as provided in RCW 19.27A.020(7), the Washington state
34 energy code for residential buildings shall be the maximum and
35 minimum energy code for residential buildings in each city, town, and
36 county and shall be enforced by each city, town, and county no later
37 than July 1, 1991.)) (1) Each city, town, and county must enforce the
38 Washington state energy code for residential buildings or adopt the
39 statewide residential reach code established pursuant to RCW
p. 2 ESHB 1770
1 19.27A.020(6). Any local residential energy code other than the
2 Washington state energy code for residential buildings and the
3 statewide residential reach code is preempted. The reach code may not
4 require more annual renewable production than a residential building
5 is predicted to use.
6 (2) The Washington state energy code for nonresidential buildings
7 shall be the minimum energy code for nonresidential buildings
8 enforced by each city, town, and county.
9 Sec. 4. RCW 19.27A.020 and 2018 c 207 s 7 are each amended to
10 read as follows:
11 (1) The state building code council in the department of
12 enterprise services shall adopt rules to be known as the Washington
13 state energy code as part of the state building code.
14 (2) The council shall follow the legislature's standards set
15 forth in this section to adopt rules to be known as the Washington
16 state energy code. The Washington state energy code shall be designed
17 to:
18 (a) Construct increasingly energy efficient homes and buildings
19 that help achieve the broader goal of building zero fossil-fuel
20 greenhouse gas emission homes and buildings by the year 2031; and
21 (b) Require new buildings to meet a certain level of energy
22 efficiency, but allow flexibility in building design, construction,
23 and heating equipment efficiencies within that framework((; and
24 (c) Allow space heating equipment efficiency to offset or
25 substitute for building envelope thermal performance)).
26 (3) The Washington state energy code shall take into account
27 regional climatic conditions. One climate zone includes: Adams,
28 Asotin, Benton, Chelan, Columbia, Douglas, Ferry, Franklin, Garfield,
29 Grant, Kittitas, Klickitat, Lincoln, Okanogan, Pend Oreille,
30 Skamania, Spokane, Stevens, Walla Walla, Whitman, and Yakima
31 counties. The other climate zone includes all other counties not
32 listed in this subsection (3). The assignment of a county to a
33 climate zone may not be changed by adoption of a model code or rule.
34 Nothing in this section prohibits the council from adopting the same
35 rules or standards for each climate zone.
36 (4) The Washington state energy code for residential buildings
37 shall be the 2006 edition of the Washington state energy code, or as
38 amended by rule by the council.
p. 3 ESHB 1770
1 (5) The minimum state energy code for new nonresidential
2 buildings shall be the Washington state energy code, 2006 edition, or
3 as amended by the council by rule.
4 (6)(((a) Except as provided in (b) of this subsection, the
5 Washington state energy code for residential structures shall preempt
6 the residential energy code of each city, town, and county in the
7 state of Washington.
8 (b) The state energy code for residential structures does not
9 preempt a city, town, or county's energy code for residential
10 structures which exceeds the requirements of the state energy code
11 and which was adopted by the city, town, or county prior to March 1,
12 1990. Such cities, towns, or counties may not subsequently amend
13 their energy code for residential structures to exceed the
14 requirements adopted prior to March 1, 1990)) The state building code
15 council must adopt by rule a statewide residential reach code for
16 optional adoption and enforcement by any city, town, or county. The
17 statewide residential reach code must achieve the 70 percent
18 reduction in energy consumption and greenhouse gas emissions required
19 in the 2030 energy code for residential buildings under RCW
20 19.27A.160 in incremental steps by the 2027 energy code. The
21 department of commerce shall develop a proposal covering the
22 technical provisions of the reach code and the rule-making documents
23 required by RCW 34.05.328. The state building code council must adopt
24 the statewide residential reach code as an appendix to the 2021
25 residential energy code to be effective by July 1, 2024.
26 (7) The state building code council shall consult with the
27 department of enterprise services as provided in RCW 34.05.310 prior
28 to publication of proposed rules. The director of the department of
29 enterprise services shall recommend to the state building code
30 council any changes necessary to conform the proposed rules to the
31 requirements of this section.
32 (8) ((The state building code council shall evaluate and consider
33 adoption of the international energy conservation code in Washington
34 state in place of the existing state energy code.
35 (9))) The definitions in RCW 19.27A.140 apply throughout this
36 section.
37 NEW SECTION. Sec. 5. A new section is added to chapter 19.27A
38 RCW to read as follows:
p. 4 ESHB 1770
1 (1) Any changes to the Washington state energy code for
2 residential buildings shall require a home affordability cost
3 analysis provided by the state building code council to determine
4 whether the changes increase or decrease the cost of accessing
5 housing.
6 (2) The state building code council may contract with a public or
7 private organization to conduct the home affordability cost analysis
8 required in subsection (1) of this section.
