State building code: Chapter 19.27 RCW.


State energy codeMinimum and maximum energy code.

Except as provided in *RCW 19.27A.020(7), the Washington state energy code for residential buildings shall be the maximum and minimum energy code for residential buildings in each city, town, and county and shall be enforced by each city, town, and county no later than July 1, 1991. The Washington state energy code for nonresidential buildings shall be the minimum energy code for nonresidential buildings enforced by each city, town, and county.

NOTES:

*Reviser's note: RCW 19.27A.020 was amended by 2009 c 423 s 4, changing subsection (7) to subsection (6).
Findings1990 c 2: "The legislature finds that using energy efficiently in housing is one of the lowest cost ways to meet consumer demand for energy; that using energy efficiently helps protect citizens of the state from negative impacts due to changes in energy supply and cost; that using energy efficiently will help mitigate negative environmental impacts of energy use and resource development; and that using energy efficiently will help stretch our present energy resources into the future. The legislature further finds that the electricity surplus in the Northwest is dwindling as the population increases and the economy expands, and that the region will eventually need new sources of electricity generation.
It is declared policy of the state of Washington that energy be used efficiently. It is the intent of this act to establish residential building standards that bring about the common use of energy efficient building methods, and to assure that such methods remain economically feasible and affordable to purchasers of newly constructed housing." [ 1990 c 2 s 1.]
Severability1990 c 2: "If any provision of this act or its application to any person or circumstance is held invalid, the remainder of the act or the application of the provision to other persons or circumstances is not affected." [ 1990 c 2 s 13.]
Effective dates1990 c 2: See note following RCW 19.27.040.



State energy codeAdoption by state building code councilPreemption of local residential energy codes.

(1) 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.
(2) 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:
(a) 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;
(b) 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; and

Hot water heatersTemperature regulation.

(1) "Hot water heater" means the primary source of hot water for a residence.
(2) The thermostat of a new water heater offered for sale or lease in this state for use in a residential unit, shall be preset by the manufacturer no higher than one hundred twenty degrees Fahrenheit (or forty-nine degrees Celsius) or the minimum setting on any water heater which cannot be set as low as that temperature. Water heating systems may utilize higher reservoir temperature if mixing valves are set or systems are designed to restrict the temperature of water to one hundred twenty degrees Fahrenheit.
(3) Upon occupancy of a new tenant in a residential unit leased or rented in this state, if hot water is supplied from an accessible, individual water heater, the water heater shall be set by the owner or agent at a temperature not higher than one hundred twenty degrees Fahrenheit (forty-nine degrees Celsius) or the minimum setting on any water heater which cannot be set as low as that temperature. Water heating systems may utilize higher reservoir temperature if mixing valves are set or systems are designed to restrict the temperature of water to one hundred twenty degrees Fahrenheit.
(4) Nothing in this section shall prohibit an owner of an owner-occupied residential unit or resident of a leased or rented residential unit from readjusting the temperature setting after occupancy. Any readjustment of the temperature setting by the resident relieves the owner or agent of an individual residential unit and the manufacturer of water heaters from liability for damages attributed to the readjustment by the resident.
(5) The utility providing energy for any water heater under this section shall at least annually, include in its billing a statement:
(a) Recommending that water heaters be set no higher than one hundred twenty degrees Fahrenheit or the minimum setting on a water heater which cannot be set as low as that temperature to prevent severe burns and reduce excessive energy consumption; and
(b) That the thermostat of an individual water heater furnished in a residential unit leased or rented in this state to new tenants shall be set no higher than one hundred twenty degrees Fahrenheit or the minimum setting on a water heater which cannot be set as low as that temperature pursuant to chapter 19.27 RCW.
(6) The manufacturer of a water heater under this section which is offered for sale or installed after July 24, 1983, shall have a tag attached to the thermostat access plate or immediately adjacent to exposed thermostats. The tag shall state that the thermostat settings above the preset temperature may cause severe burns and consume excessive energy.
(7) Nothing in this section requires or permits any inspections other than those otherwise required or permitted by law.
(8) This section does not apply to multiple-unit residences supplied by central water heater systems.

NOTES:

Findings1983 c 178: "The legislature recognizes that unnecessarily hot tap or bath water creates an extreme risk of severe burns, especially among the elderly, children, and retarded persons. Annually, numerous persons suffer severe scald burns, some resulting in death, from tap or bath water which is inordinately hot. Excessive tap and bath water temperatures in residential usage is unnecessary for sanitary purposes. Regulation of the setting of water temperatures upon installation can virtually eliminate incidences of dangerous scalding. Further, the legislature finds that projected future shortages of energy in our state could be reduced or prevented by the efficient utilization of existing energy resources. Reducing the temperature settings on thermostats to one hundred twenty degrees Fahrenheit (or forty-nine degrees Celsius) would save energy that is now unnecessarily consumed, reduce homeowners' average utility costs, and promote home safety without any loss of comfort or health." [ 1983 c 178 s 1.]

ViolationsPenalty.

The penalty for failure to comply with RCW 19.27A.080 through 19.27A.120 is a misdemeanor.



Finding2009 c 423.

The legislature finds that energy efficiency is the cheapest, quickest, and cleanest way to meet rising energy needs, confront climate change, and boost our economy. More than thirty percent of Washington's greenhouse gas emissions come from energy use in buildings. Making homes, businesses, and public institutions more energy efficient will save money, create good local jobs, enhance energy security, reduce pollution that causes global warming, and speed economic recovery while reducing the need to invest in costly new generation. Washington can spur its economy and assert its regional and national clean energy leadership by putting efficiency first. Washington can accomplish this by: Promoting super efficient, low-energy use building codes; requiring disclosure of buildings' energy use to prospective buyers; making public buildings models of energy efficiency; financing energy saving upgrades to existing buildings; and reducing utility bills for low-income households.

NOTES:

Reviser's note: The definitions in this section have been alphabetized pursuant to RCW 1.08.015(2)(k).
FindingsIntent2022 c 177: "The legislature finds that in order to meet the statewide greenhouse gas emissions limits in RCW 70A.45.020, the state must require performance standards for existing buildings.
In order to have a comprehensive understanding of the need and potential for updating the state's building stock, including the "split incentive issue" in which tenants are responsible for energy costs and building owners are responsible for choices about energy systems and building maintenance, more robust benchmarking and reporting for building performance, operations, and maintenance is needed. While the state has adopted comprehensive reporting requirements for larger buildings, it currently lacks similar requirements for smaller buildings. It is the intent of the legislature to extend existing building benchmarking, energy management, and operations and maintenance planning requirements to smaller commercial and multifamily residential buildings in order to assess the needs and opportunities for job creation and incentives and environmental and public health improvements.
The legislature further finds that in order to meet the statewide greenhouse gas emissions limits in the energy sectors of the economy, more resources must be directed toward achieving decarbonization of building heating and cooling loads, while continuing to relieve energy burdens that exist in overburdened communities. These resources must include comprehensive customer support, outreach, and technical assistance. These efforts must include notifying building owners of requirements through communications campaigns, providing resources to aid in compliance, and delivering training to equip building owners, and the industry, to be successful."

State energy performance standard.

(1)(a) By November 1, 2020, the department must establish by rule a state energy performance standard for covered commercial buildings.
(b) In developing energy performance standards, the department shall seek to maximize reductions of greenhouse gas emissions from the building sector. The standard must include energy use intensity targets by building type and methods of conditional compliance that include an energy management plan, operations and maintenance program, energy efficiency audits, and investment in energy efficiency measures designed to meet the targets. The department shall use ANSI/ASHRAE/IES standard 100-2018 as an initial model for standard development. The department must update the standard by July 1, 2029, and every five years thereafter. Prior to the adoption or update of the standard, the department must identify the sources of information it relied upon, including peer-reviewed science.
(2) In establishing the standard under subsection (1) of this section, the department:
(a) Must develop energy use intensity targets that are no greater than the average energy use intensity for the covered commercial building occupancy type with adjustments for unique energy using features. The department must also develop energy use intensity targets for additional property types eligible for incentives in RCW 19.27A.220. The department must consider regional and local building energy utilization data, such as existing energy star benchmarking data, in establishing targets for the standard. Energy use intensity targets must be developed for two or more climate zones and be representative of energy use in a normal weather year;
(b) May consider building occupancy classifications from ANSI/ASHRAE/IES standard 100-2018 and the United States environmental protection agency's energy star portfolio manager when developing energy use intensity targets;
(c) May implement lower energy use intensity targets for more recently built covered commercial buildings based on the state energy code in place when the buildings were constructed;
(d)(i) Must adopt a conditional compliance method that ensures that covered commercial buildings that do not meet the specified energy use intensity targets are taking action to achieve reduction in energy use, including investment criteria for conditional compliance that ensure that energy efficiency measures identified by energy audits are implemented to achieve a covered commercial building's energy use intensity target. The investment criteria must require that a building owner adopt an implementation plan to meet the energy intensity target or implement an optimized bundle of energy efficiency measures that provides maximum energy savings without resulting in a savings-to-investment ratio of less than 1.0, except as exempted in (d)(ii) of this subsection. The implementation plan must be based on an investment grade energy audit and a life-cycle cost analysis that accounts for the period during which a bundle of measures will provide savings. The building owner's cost for implementing energy efficiency measures must reflect net cost, excluding any costs covered by utility or government grants. The implementation plan may exclude measures that do not pay for themselves over the useful life of the measure and measures excluded under (d)(ii) of this subsection. The implementation plan may include phased implementation such that the building owner is not required to replace a system or equipment before the end of the system or equipment's useful life;
(ii) For those buildings or structures that are listed in the state or national register of historic places; designated as a historic property under local or state designation law or survey; certified as a contributing resource with a national register listed or locally designated historic district; or with an opinion or certification that the property is eligible to be listed on the national or state registers of historic places either individually or as a contributing building to a historic district by the state historic preservation officer or the keeper of the national register of historic places, no individual energy efficiency requirement need be met that would compromise the historical integrity of a building or part of a building;
(e) Must provide an alternative compliance pathway for an owner of a state campus district energy system, in accordance with RCW 19.27A.260, and more broadly for the owner of any campus district energy system that is approved by the department to opt-in in accordance with RCW 19.27A.260(6);
(f) Must guarantee that the owner of a state campus district energy system is not required to implement more than one energy management plan and more than one operations and maintenance plan for the campus;
(g) Must guarantee that a state campus district energy system, as defined in RCW 19.27A.260, and all buildings connected to a state campus district energy system, are in compliance with any requirements for campus buildings to implement energy efficiency measures identified by an energy audit if:
(i) The energy audit demonstrates the energy savings from the state campus district energy system energy efficiency measures will be greater than the energy efficiency measures identified for the campus buildings; and
(ii) The state campus district energy system implements the energy efficiency measures.
(3) Based on records obtained from each county assessor and other available information sources, the department must create a database of covered commercial buildings and building owners required to comply with the standard established in accordance with this section.
(4) By July 1, 2021, the department must provide the owners of covered buildings with notification of compliance requirements.
(5) The department must develop a method for administering compliance reports from building owners.
(6) The department must provide a customer support program to building owners including, but not limited to, outreach and informational material, periodic training, phone and email support, and other technical assistance.
(7) The building owner of a covered commercial building must report the building owner's compliance with the standard to the department in accordance with the schedule established under subsection (8) of this section and every five years thereafter. For each reporting date, the building owner must submit documentation to demonstrate that:
(a) The weather normalized energy use intensity of the covered commercial building measured in the previous calendar year is less than or equal to the energy use intensity target; or
(b) The covered commercial building has received conditional compliance from the department based on energy efficiency actions prescribed by the standard; or
(c) The covered commercial building is exempt from the standard by demonstrating that the building meets one of the following criteria:
(i) The building did not have a certificate of occupancy or temporary certificate of occupancy for all 12 months of the calendar year prior to the building owner compliance schedule established under subsection (8) of this section;
(ii) The building did not have an average physical occupancy of at least 50 percent throughout the calendar year prior to the building owner compliance schedule established under subsection (8) of this section;
(iii) The sum of the building's gross floor area minus unconditioned and semiconditioned spaces, as defined in the Washington state energy code, is less than 50,000 square feet;
(iv) The primary use of the building is manufacturing or other industrial purposes, as defined under the following use designations of the international building code: (A) Factory group F; or (B) high hazard group H;
(v) The building is an agricultural structure; or
(vi) The building meets at least one of the following conditions of financial hardship: (A) The building had arrears of property taxes or water or wastewater charges that resulted in the building's inclusion, within the prior two years, on a city's or county's annual tax lien sale list; (B) the building has a court appointed receiver in control of the asset due to financial distress; (C) the building is owned by a financial institution through default by a borrower; (D) the building has been acquired by a deed in lieu of foreclosure within the previous 24 months; (E) the building has a senior mortgage subject to a notice of default; or (F) other conditions of financial hardship identified by the department by rule.

NOTES:

Findings2023 c 291: See note following RCW 19.27A.260.
Explanatory statement2021 c 65: See note following RCW 53.54.030.
FindingIntent2019 c 285: "(1) The legislature finds that state policy encouraging energy efficiency has been extremely successful in reducing energy use, avoiding costly investment in new generating capacity, lowering customer energy bills, and reducing air pollution and greenhouse gas emissions. The state's 2019 biennial energy report indicates that utility conservation investments under chapter 19.285 RCW, the energy independence act, now save consumers more than seven hundred fifty million dollars annually, helping to keep Washington's electricity prices among the lowest in the nation.
(2) Studies by the Northwest power and conservation council and by individual Washington utilities repeatedly show that efficiency is the region's largest, cheapest, lowest risk energy resource; that without it, the Northwest would have needed to invest in additional natural gas-fired generation; and that, looking ahead, efficiency can approach the size of the region's hydropower system as a regional resource. The Northwest power and conservation council forecasts that with an aggressive new energy efficiency policy, the region can potentially meet one hundred percent of its electricity load growth over the next twenty years with energy efficiency.
(3) Energy efficiency investments that reduce energy use in buildings bring cobenefits that directly impact Washingtonians' quality of life. These benefits include improved indoor air quality, more comfortable homes and workplaces, and lower tenant energy bills. The legislature notes that according to the United States department of energy's energy and employment report, 2017, the energy efficiency sector has created more than sixty-five thousand jobs in the state, more than two-thirds of which are in the construction sector, and that the number continues to grow.
(4) Considering the benefits of and the need for additional energy efficiency to meet regional energy demand, the legislature notes that attaining as much of this resource as possible from the buildings sector can have a significant effect on state greenhouse gas emissions by deferring or displacing the need for natural gas-fired electricity generation and reducing the direct use of natural gas. Buildings represent the second largest source of greenhouse gas emissions in Washington and emissions from the buildings sector have grown by fifty percent since 1990, far outpacing all other emission sources.
(5) The legislature therefore determines that it is in the state's interest to maximize the full potential of energy efficiency standards, retrofit incentives, utility programs, and building codes to keep energy costs low and to meet statutory goals for increased building efficiency and reduced greenhouse gas emissions.
(6) It is the intent of this act to provide incentives and regulations that encourage greater energy efficiency in all aspects of new and existing buildings, including building design, energy delivery, and utilization and operations. This act:
(a) Establishes energy performance standards for larger existing commercial buildings;
(b) Provides financial incentives and technical assistance for building owners taking early action to meet these standards before they are required to be met;
(c) Enhances access to commercial building energy consumption data in order to assist with monitoring progress toward meeting energy performance standards; and
(d) Establishes efficiency performance requirements for natural gas distribution companies, recognizing the significant contribution of natural gas to the state's greenhouse gas emissions, the role that natural gas plays in heating buildings and powering equipment within buildings across the state, and the greenhouse gas reduction benefits associated with substituting renewable natural gas for fossil fuels." [ 2019 c 285 s 1.]



State energy performance standardEarly adoption incentive programReport to the legislature.

(1) The department must establish a state energy performance standard early adoption incentive program consistent with the requirements of this section. This early adoption incentive program may include incentive payments for early adoption of tier 2 covered building owner requirements as described in subsection (6) of this section.

(6)(a) A tier 2 covered building owner may receive an incentive payment in the amounts specified in subsection (8)(b) of this section only if all required benchmarking, energy management, and operations and maintenance planning documentation as required under RCW 19.27A.250 has been submitted to the department and an incentive application has been completed.
(b) An eligible tier 2 covered building owner may submit an application beginning July 1, 2025, through June 1, 2030.
(7) The department must review each application and determine whether the applicant is eligible for the incentive program and if funds are available for the incentive payment within the limitation established in RCW 19.27A.230. If the department certifies an application, it must provide verification to the building owner and each entity participating as provided in RCW 19.27A.240 and providing service to the building owner.
(8)(a) An eligible owner of a tier 1 covered building or an eligible owner of a multifamily residential building greater than 50,000 gross square feet, excluding the parking area, that demonstrates early compliance with the applicable energy use intensity target under the standard established under RCW 19.27A.210 may receive a base incentive payment of 85 cents per gross square foot of floor area, excluding parking, unconditioned, or semiconditioned spaces. The department may provide incentives greater than the base incentive payment for upgrading tier 1 buildings.
(b) A tier 2 eligible building owner that demonstrates compliance with the applicable benchmarking, energy management, and operations and maintenance planning requirements may receive a base incentive payment of 30 cents per gross square foot of floor area, excluding parking, unconditioned, or semiconditioned spaces. The department may provide incentives greater than the base incentive payment for upgrading tier 2 buildings. The department may implement a tiered incentive structure for upgrading multifamily buildings to provide an enhanced incentive payment to multifamily building owners willing to commit to antidisplacement provisions.
(9) The incentives provided in subsection (8) of this section are subject to the limitations and requirements of this section, including any rules or procedures implementing this section.
(10) The department must establish requirements for the verification of energy consumption by the building owner and each participating electric utility, gas company, and thermal energy company.
(11) The department must provide an administrative process for an eligible building owner to appeal a determination of an incentive eligibility or amount.

State energy performance standardEarly adoption incentive payment administration.

(1)(a) Each qualifying utility must administer incentive payments for the state energy performance standard early adoption incentive program established in RCW 19.27A.220 on behalf of its customers who are eligible building owners of covered commercial buildings, multifamily residential buildings, or other tier 2 covered buildings consistent with the requirements of this section. Any thermal energy company, electric utility, or gas company not otherwise required to administer incentive payments may voluntarily participate by providing notice to the department in a form and manner prescribed by the department.
(b) Nothing in this subsection (1) requires a qualifying utility to administer incentive payments for the state energy performance standard early adoption incentive program established in RCW 19.27A.220 for which the qualifying utility is not allowed a credit against taxes due under this chapter, as described in RCW 82.16.185.
(2) An entity that administers the payments for the incentive program under this section must administer the program in a manner that is consistent with the standard established and any rules adopted by the department under RCW 19.27A.210, 19.27A.220, and 19.27A.250.
(3) Upon receiving notification from the department that a building owner has qualified for an incentive payment, each entity that administers incentive payments under this section must make incentive payments to its customers who are eligible building owners of covered commercial buildings or multifamily residential buildings who qualify as provided under this section and at rates specified in RCW 19.27A.220(8). When a building is served by more than one entity administering incentive payments, incentive payments must be proportional to the energy use intensity reduction of the participating entities' fuel.
(4) The participation by an entity in the administration of incentive payments under this section does not relieve the entity of any obligation that may otherwise exist or be established to provide customer energy efficiency programs or incentives.
(5) An entity that administers the payments for the incentive program under this section is not liable for excess payments made in reliance on amounts reported by the department as due and payable as provided under RCW 19.27A.220, if such amounts are later found to be abnormal or inaccurate due to no fault of the business.

NOTES:

Findings2023 c 291: "The legislature recognizes that building decarbonization is necessary to achieve the state's climate goals. Washington is a member of the national building performance standards coalition and is leading the nation with existing building performance standards. District energy policy could be used in coordination with any future statewide building performance standards policies to reduce commercial and large state-owned building emissions.
Due to the increased prevalence of extreme summer heat events, the ability to cool space at our state-run campus facilities, including correctional facilities, is an essential function of maintaining humane living, working, and learning conditions.
Upgrading existing district energy systems has great potential to increase efficiency, oftentimes more so than a building-by-building approach.
Upgrading and constructing district energy systems will employ skilled labor, including trades that have historically performed work on fossil fuel energy sources. This work will be an important part of a just transition to a clean energy economy.
For state-owned facilities connected to district energy systems, the legislature recognizes that it may take years, multiple budget cycles, and commitments as anchor customers to develop and upgrade campus district energy systems, but remains committed to steadily investing in plans developed by these agencies and their selected providers. Having plans for multiyear customer commitments or spending programs will set the state and private sector up well for applying for federal grants and resources and to appropriately plan capital, operating, and climate commitment act funding for these investments over time."

New housing in existing buildingsAdoption of rule.

By January 1, 2024, the state building code council shall adopt by rule an amendment to the current energy code that waives the requirement for unchanged portions of an existing building used for residential purposes to meet the current energy code solely because of the addition of new dwelling units within the building. New dwelling units created within the existing building must meet the requirements of the current energy code.
