RESOLUIION OF THE CIIY COUNCIL OF IHE CIIY OF CHULA VISIA ADOPIING IHE CHULA VISTA GREEN BUILDING STANDARDS. Submitted By: Building Official On ,July 10, 2008, Council approved Resolution No 2008-177 in which Council adopted the implementation plans for the Climate Change Working Group (CCWG) measures. Measure # 4, Green Building Standards, consists of several components, one of which is the adoption of the State Housing and Community Development's (HCD) standards that are in the California Green Building Standards Code (CGBSC) the proposed ordinance, Attachment "A", adopts HCD's green building standards and requires all residential and non-residential construction to comply with the adopted standards. RRC(1MMF'.NT)ATTON: Recommend to City Council the adoption of the ordinance and resolution, T)TSCT 1SRTON• Green building is a whole system approach to the design, construction and operation of buildings that employs materials and methods that promote natural resource conservation, energy efficiency and good indoor air quality., Paint, adhesives, carpets, and wood, among other building materials, generally contain a wide array of chemical pollutants. These toxic substances continue to be released into the indoor and outdoor atmosphere long afrer construction has been completed, They can contaminate the air and water; and some substances remain in the environment for many years. Because green buildings contain low-emitting materials, they pose less of a risk to the building's occupants and the natural environment. Significant health benefits can be gained like increased productivity and reduced absenteeism due to illness Furthermore, reducing the need for water reduces shess on the local water infrastructure and results in energy and carbon savings from the reduced amount of water that needs to be transported and distributed. This will also reduce the generation of wastewater reducing the need for sewer infrastructure expansion, The California Building Standards Commission (BSC) and the Department of Housing and Community Development (HCD) developed and approved a California Green Building Standards Code (CGBC) gleaned from nationally recognized programs and based on an open public adoption process, The BSC regulations for nonresidential buildings is currently intended to be a voluntary guideline, while HCD's requirements for housing will become mandatory by F:\CVGBP\CVGBP Ordinances\BOAA Green Building Ord,dac Board of Appeals and Advisors Meeting Date 08/10/09 Page 2 State Law on Januazy 1, 2011, and will be incorporated into the California building codes. HCD's water efficiency and conservation measures will become mandatory on ,July 1, 2011. the Implementation Plan proposed the early adoption of the State Housing and Community Development's (HCD) version of the California Green Building Standards Code (CGBSC) As proposed, the standards would apply to all new residential construction, remodels, additions, and alterations, and to all new nonresidential construction, remodels, additions, and tenant improvements, the Chnla Vista ('rrPPn Rnilding 4tandard.v (CVGBS), Exhibit "A" to the proposed City Council resolution, Attachment "B", lists the City's proposed green building standards Some of the standards such as site development and construction waste reduction are existing requirements in the City's Municipal Code,. They are included to reference the existing standaz~ds,. Staff' is not aware of any formal analysis on the upfront cost of implementing HCD's green building standazds, However; based on discussions with HCD staff and energy consultants, incorporating HCD's green building features into a new residence will add about $0.,40 to $0.80 per square foot to the construction cost.. Ihis equates to 0.3% to 0 7% of the construction cost of a new residence assuming a $120 per square foot building construction cost. Ihis upfront cost should decrease as green building resources become more available in the market and the construction industry becomes more accustomed to green building practices. As for savings to the occupant, the 20% reduction in indoor water consumption should lower the monthly water bill by about 10% assuming that 50% of the total water consumption is indoor water. This should also lower the sewer bill due to the reduction in wastewater Building permit fees will need to be adjusted to recover the cost of plan review and inspection. Staff estimates that it will take an additional hour of staff time to review and inspect a typical 2,500 square foot house.. The additional staff time will vary based on the type and size of buildings, the additional staff time will be accounted for in a comprehensive building permit fee study which we anticipate to complete and take to City Council in December 09 Staff' is being trained on the CVGBS and is developing informational handouts and guides that will be made available to the public. If the Board approves a motion to recommend to the City Council the adoption of the ordinance and resolution, staff will take the ordinance to City Council in early September 2009.. the adopted ordinance will then have to be filed with the BSC before it can take effect.

AN ORDINANCE OF IHE CIIY OF CHULA VISTA ADDING CHAPTER 15.12, GREEN BUILDING STANDARDS, IO THE CHULA VISTA MUNICIPAL CODE., B RESOLUTION OF THE CIIY COUNCIL OF THE CIIY OF CHULA VISIA ADOPIING THE CHULA VISIA GREEN BUILDING SIANDARDS. F:\CVGBP\CVGBP Ordinances\BOAA Green Building Ord doc Attachment A ORDINANCE NO. AN ORDINANCE OF IHE CITY OF CHULA VISIA ADDING CHAPIER 15.12, GREEN BUILDING STANDARDS, IO THE CHULA VISIA MUNICIPAL CODE The City Council of the City of Chula Vista does ordain as follows: SECTION I, Findings,. The City Council finds as follows: 1. the City of Chula Vista has a long standing commitment to leadership in green building standards, sustainable design and construction practices, water and other resource conservation and the reduction of greenhouse gas emissions.. The City has committed to reducing its citywide greenhouse gas (GHG) emissions to 20% below 1990 levels by 2010, 2. GHG reduction has been mandated by Governor Schwarzenegger through executive orders and in his signing into law AB 32 in 2006., AB 32 requires a reduction of GHG emissions to 1990 levels by 2020. 3, A 2005 Greenhouse Gas Emissions Inventory indicated that Chula Vista's annual citywide greenhouse gas levels had increased by 35% since 1990 due primarily to residential growth. 4 According to studies published by the United States Green Building Council, the construction, demolition and operation of buildings in the United States collectively consume up to 39% of the total energy used, 12% of all fresh water supply, and 40% of all raw materials used in the United States Buildings also generate 39% of total emission of greenhouse gases,. 5, the California Building Standards Commission (CBSC) and the Department of Housing and Community Development (HCD) developed and approved a California Green Building Standards Code (CGBSC) gleaned from nationally recognized programs and based on an open public adoption process. 6. Green building design, construction, and operation can have a significant positive effect on resource conservation, energy efficiency, waste and pollution generation, and the health and productivity of a building's occupants over the life of the building. Requiring commercial and residential projects to incorporate green building measures is necessary and appropriate to achieve the public health and welfare benefits of green building., 7 Modifications to the California Building Standards, as detailed in this Ordinance, are reasonably necessary due to local climatic conditions, As a result of high summer ambient temperatures and periods of heat waves, average load demand and peak load demand of energy used in Chula Vista is an important factor concerning public safety and adverse economic impacts of power outages or power reductions. Reduction of total and peak energy use will have local and regional benefits in the reduction of energy costs for Ordinance No, Page 2 the building owner; additional available system energy capacity, and a reduction in greenhouse gas emissions SECIION II That Chapter 15.12 is added to the Chula Vista Municipal Code and reads as follows: Chapter 15.12 Green Building Standards Sections: Section 15 12.001 Purpose Section 1512..005 Scope Section 15..12.010 Definitions Section 15..12.015 Conflicting Provisions Section 15.12 020 Administration Section 15.12025 Alternate Materials, Methods of Design and Methods of Construction Section 15 12,0.30 Green Building Standards Section 15.12.035 Administrative Procedures Section 15,12..040 Appeal Section 15.12.001 Purpose the purpose of this Chapter is to enhance the public health and welfare by promoting the environmental and economic health of the City through the design, construction, maintenance, operation and deconstruction of buildings and other site development by incorporating green building practices into all development.
