Background: The goal of green buildings is to use energy, water, and natural resources efficiently; protect human health; and reduce waste, pollution, and environmental impacts. The process for constructing a green building includes an assessment of the site and design, construction, operation, and maintenance.

There are national and state associations for green and sustainable home builders to provide assistance to those who choose to use environmentally friendly building practices and the construction of homes that are energy and resource efficient. These associations have standards and verification processes to ensure that homes are built to meet certain energy efficiency, water use, and health and indoor air criteria. Some associations provide varying levels of certification depending on the criteria met during construction and features included in the home. Third-party verification is an option in some programs to evaluate and authenticate information provided by the builder and achievement of a specified level of performance.

Some homebuilders have raised concerns about homes being sold as green or energy efficient that do not have features for energy efficiency, conservation of water and natural resources, or indoor air quality.

Summary of Engrossed Substitute Bill: By December 1, 2011, the State Building Code Council (SBCC), in collaboration with interested stakeholders, must review local and nationally recognized green building and energy efficiency programs and standards that establish criteria for energy efficiency, indoor air quality, and environmental responsibility, and provide varying levels of green home certification; establish national accreditation or certification criteria for third-party inspection firms for compliance with green building and energy efficiency programs; evaluate the feasibility of creating a residential energy code appendix; and identify and evaluate the impacts to local jurisdictions required to implement the definitions of green home and energy efficient homes.

The SBCC must provide a report to the Legislature that includes recommendations for the expected percent of energy efficiency gains above the national model energy codes; to facilitate implementation of the definitions of green homes and energy efficient homes by local jurisdictions; and for consideration of embodied energy consumption in differing types of construction materials.

By December 1, 2012, the SBCC must adopt rules to define a green home and an energy efficient home. The definitions must be developed in consideration of the information and recommendations gained from the review of local and national energy efficient and green home criteria.

The SBCC must review the rules every three years, coinciding with the reviews and updates to the State Energy Code. The review must be included as an element of the Washington State Energy Code Progress Report. The definitions for green home and energy efficient home must be reviewed in 2030, and the definitions expire in 2031, unless extended by the Legislature.

The SBCC, after considering the feasibility of creating a residential energy code appendix, may publish an appendix of the requirements for an energy efficient home for each revised edition of the State Energy Code. In addition, the SBCC must provide compliance methods using prescriptive, component performance, and systems analysis approaches, and prescribe labels for an energy efficient home consistent with requirements of the State Energy Code.

A local building department or a third-party inspector approved by a local building department may review plans and inspect energy efficient homes.

Staff Summary of Public Testimony on Proposed Substitute as Heard In Committee: PRO: The bill provides a way for people to know that if a house is labeled green or energy efficient, it is what they're buying. There should be a way for consumers to know what they are buying. There are homes being marketed as green when they may just be code homes. Consumers should have the assurance that a home advertised as green is green. The bill needs to clearly articulate that other types of dwellings are included.

CON: It will be very expensive for the state to monitor. The existing green building programs should be recognized to do the inspections. Some aspects of green buildings have no relationship to the structural integrity of a building and therefore may not fit within an inspection regime of a building department. We need to educate the consumers and tenants of these buildings so that they know what green is and that the buildings are used appropriately. It is not clear as the building code changes if the status of a green building retains a green label it obtained in previous years. It would be difficult to document damages to consumers. There are controls in place for real estate licensees. Washington State has one of the most energy efficient building codes in the nation and therefore all of the homes built in the state are energy efficient. There should be a way to certify green homes on varying levels or a sliding scale.

OTHER: The goals of the bill are good. The SBCC should be directed to study how to set a standard instead of setting the standard at this time. There are many private industry standards now, and this bill would pick winners and losers. Last year's legislation required the energy code to be 15 percent more efficient. This is a good goal, but we would want the SBCC to look at the energy efficiency requirement in this bill to see if it is realistic.
