18944.50.
The Legislature finds and declares all of the following:(a) California is committed to providing leadership on energy, environmental, and public health issues by implementing innovative and resource efficient building design practices and other programs that improve the lives of the state’s 35,000,000 residents.
(b) Buildings account for nearly 40 percent of the carbon dioxide emissions in the United States, more than any other sector.
(c) In 2006, the state had approximately 13,000,000 existing housing units, and in 2003, construction investment in the state for new residential housing totaled thirty-four billion dollars
($34,000,000,000).
(d) The building of a 2,000-square-foot home generates three to five tons of construction waste. Cumulatively, California residences use approximately 5,600,000 acre-feet of applied water annually, and the residential sector accounts for roughly 31 percent of the electricity consumed in the state.
(e) Transforming the building environment to be more energy efficient and climate friendly is a vital tool in the fight against global warming.
(f) Sustainable building practices utilize energy, water, and materials efficiently throughout the building’s life cycle; enhance indoor air quality; improve health, comfort, and productivity; incorporate environmentally preferable products, and thereby substantially reduce the costs and environmental impacts associated with long-term building operations, without
compromising building performance or the needs of future generations.
(g) The widespread implementation of sustainable building standards would result in significant long-term benefits to the California environment, including reduction of runoff of water pollutants to surface water and groundwater sources, and reduction in the demand for energy, water, and sewage treatment services, as well as the fiscal and environmental impacts resulting from the expansion of these infrastructures.
(h) A United Nations’ study showed that better architecture and energy savings in buildings could do more to fight global warming than all the curbs on greenhouse gases agreed to under the United Nations’ Kyoto Protocol.
(i) Indepth studies of projects to analyze the cost of sustainable buildings, using detailed cost estimates,
demonstrate that there may be no significant difference in the construction costs for the United States Green Building Council’s Leadership in Energy and Environmental Design (LEED) buildings versus non-LEED buildings in any of the categories.
(j) A building’s energy, water, and waste disposal costs are computed over a 25-year period, or for the life of the building, and can exceed the cost of design and construction.
18944.56.
(a) On or before July 1, 2009, the Department of Housing and Community Development shall develop green building standards for residential occupancies and submit them to the commission for review, adoption, approval, and publication.(b) The green building standards developed pursuant to this section shall include, but not be limited to, all of the following:
(1) Energy efficiency, conservation, or renewable generation measures.
(2) Water efficiency, conservation, and reuse measures.
(3) Materials and resources efficiency, conservation, and reuse
measures.
(4) Indoor environmental quality measures, including indoor air quality.
(5) Innovation and design process.
(6) Nonmotorized or public transportation.
(7) A method for determining life-cycle cost, including evaluating the relative effectiveness, cost, and life-cycle savings, if any, by the use of the individual or multiple green building measures specified in paragraphs (1) to (6), inclusive.
(c) To develop the green building standards pursuant to this section, the Department of Housing and Community Development shall coordinate a working group consisting of a multiagency effort, including, but not limited to, all of the following state entities:
(1) The California Environmental Protection Agency.
(2) The California Integrated Waste Management Board.
(3) The State Energy Resources Conservation and Development Commission.
(4) The State Air Resources Board.
(5) The Department of Water Resources.
(6) The Department of Housing and Community Development.
(7) The Department of General Services.
(8) The commission.
(9) The Office of the State Fire Marshal.
(d) The Department of Housing and Community Development and each state entity specified in subdivision (c) shall also consult with representatives from each of the following:
(1) The building design and construction industry.
(2) Recognized environmental and housing consumer advocacy groups.
(3) Interested local government entities.
(4) Interested public parties.
(e) Each state entity specified in subdivision (c) shall take the lead in developing recommendations for green building standards related to its particular area of expertise and may also review and comment on proposed recommendations from other state entities in order
to ensure consistency with the missions, standards, and regulations of its own entity. After the Department of Housing and Community Development coordinates and considers the separate green building standards recommended by the other state entities, the Department of Housing and Community Development shall develop a set of residential green building standards and propose those green building standards to the commission.
(f) In developing and adopting green building standards pursuant to this chapter, all entities involved shall consider those aspects of existing relevant guidelines that maximize the measures and methods identified in subdivision (b). The Department of Housing and Community Development, in consultation with the commission, shall request the appropriate state entities listed in subdivision (c) to identify the relevant green building guidelines that further the purposes of this chapter, which shall include, but not be limited to,
all of the following as long as they are in effect:
(1) The United States Green Building Council’s Leadership in Energy and Environmental Design (LEED) for Homes rating system.
(2) The Build It Green “New Home Construction Green Building Guidelines.”
(3) The EarthCraft House program of Atlanta, Georgia.
(4) The Built Green program of the Seattle Master Builders.
(5) The Model Green Home Building Guidelines of the National Association of Home Builders (NAHB).
(g) To the extent feasible as allowed by existing resources, the Department of Housing and Community Development and the commission may develop educational and technical assistance programs to inform local
entities of the benefits of green building, and encourage the use of green building practices for residential occupancies, as well as establish ongoing education and training programs for local code enforcement officials, designers, and builders on the subject of green building standards.
(h) On or before July 1, 2010, the commission shall publish approved green building standards in accordance with Section 18944.60 and, to the extent practicable, shall schedule that publication to coincide with the publication of the California Building Standards Code.
(i) The Department of Housing and Community Development shall not propose changes more than once per calendar year, and, to the extent practicable, shall coincide those changes with the review of the California Building Standards Code.
(j) Those entities specified in subdivision (c) with expertise related to green building as identified in subdivision (e) may submit to the
Department of Housing and Community Development proposed changes to building standards developed pursuant to subdivision (b) of Section 18944.54 and this section, related to their area of expertise. The proposed building standards shall not reduce the environmental benefits, environmental efficiencies, or public health protections that would have been achieved by the existing standards. The commission shall consult with appropriate agencies and departments on the proposed changes prior to adoption.
(k) The commission may include in an appendix or as a separate green building document or some combination thereof, voluntary building standards or other related documents and materials that are not appropriate for a mandate in the California Building Standards Code.
(l) This section does not prohibit, limit, or supersede other green building standards developed pursuant to existing authority.
