In order to meet the statewide greenhouse gas emissions limits in RCW 70A.45.020, the state must require construction of increasingly low-emission energy efficient homes and buildings and achieve construction of zero fossil-fuel greenhouse gas emission homes and buildings by 2030. Top categories of clean energy jobs in the buildings sector include: High-efficiency heating, ventilation, and air conditioning; energy efficiency technologies; and renewable heating and cooling. As the fastest growing clean energy industries in our state, work in these areas also supports job creation in other construction trades, which is a critical component of a clean energy economic recovery strategy.
This section modifies existing section 19.27A.160. Here is the modified chapter for context.
Except as provided in subsection (2) of this section, residential and nonresidential construction must achieve the following:
A reduction of at least 70 percent in annual net energy consumption under the residential and nonresidential energy codes that become effective in 2031, using the adopted 2006 Washington state energy code as a baseline; and
New buildings must be net-zero ready, including a reduction of at least 80 percent in annual net energy consumption using the adopted 2006 Washington state energy code as a baseline and must include wiring for photovoltaic panel installation under the residential and nonresidential state energy codes that are adopted by the council by 2034. The state building code council shall further define and include net-zero ready measures in the code adoption process.
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 requirements 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.
This section modifies existing section 19.27A.015. Here is the modified chapter for context.
Each city, town, and county must enforce the Washington state energy code for residential buildings or adopt the statewide residential reach code established pursuant to RCW 19.27A.020(6). Any local residential energy code other than the Washington state energy code for residential buildings and the statewide residential reach code is preempted. The reach code may not exceed net-zero energy use.
The Washington state energy code for nonresidential buildings shall be the minimum energy code for nonresidential buildings enforced by each city, town, and county.
This section modifies existing section 19.27A.020. Here is the modified chapter for context.
The state building code council in the department of enterprise services shall adopt rules to be known as the Washington state energy code as part of the state building code.
The council shall follow the legislature's standards set forth in this section to adopt rules to be known as the Washington state energy code. The Washington state energy code shall be designed to:
Construct increasingly energy efficient homes and buildings that help achieve the broader goal of building zero fossil-fuel greenhouse gas emission homes and buildings by the year 2031; and
Require new buildings to meet a certain level of energy efficiency, but allow flexibility in building design, construction, and heating equipment efficiencies within that framework
.
The Washington state energy code shall take into account regional climatic conditions. One climate zone includes: Adams, Asotin, Benton, Chelan, Columbia, Douglas, Ferry, Franklin, Garfield, Grant, Kittitas, Klickitat, Lincoln, Okanogan, Pend Oreille, Skamania, Spokane, Stevens, Walla Walla, Whitman, and Yakima counties. The other climate zone includes all other counties not listed in this subsection (3). The assignment of a county to a climate zone may not be changed by adoption of a model code or rule. Nothing in this section prohibits the council from adopting the same rules or standards for each climate zone.
The Washington state energy code for residential buildings shall be the 2006 edition of the Washington state energy code, or as amended by rule by the council.
The minimum state energy code for new nonresidential buildings shall be the Washington state energy code, 2006 edition, or as amended by the council by rule.
6.
The state building code council must adopt by rule a statewide residential reach code for optional adoption and enforcement by any city, town, or county. The statewide residential reach code must achieve the reductions in energy consumption and greenhouse gas emissions required in the 2031 energy code for residential buildings under RCW 19.27A.160. The department of commerce shall develop a proposal covering the technical provisions of the reach code. The state building code council must adopt the statewide residential reach code as an appendix to the 2021 residential energy code to be effective by 2023.

The definitions in RCW 19.27A.140 apply throughout this section.
