Today’s Objectives Why a CALGreen CodeHow the CALGreen Code was developed Rulemaking process Transparency of process Overview of Non-Residential Code Provisions
California GHG EmissionsCalifornia Green Building Initiative & Global Warming Solutions Act of 2006 (EO S & AB32) Buildings are 2nd largest contributor (23.7%) to GHG emissions EO S-20-04: Reduce grid-based electricity by 20% in state-owned buildings by 2015; reduce associated greenhouse gas emissions AB 32: Reduce GHG emissions to 1990 levels by 2020 California GHG Emissions
Water Use in CaliforniaExecutive Order S-06-08 Governor’s 2009 Proclamation Water-related uses account for 19% of California's electricity, 30% of its natural gas and 88 billion gallons of diesel fuel every year. Water-efficiency measures can reduce water and sewer costs by up to 30 percent. Significant savings in energy, chemical and maintenance expenses typically follow.

California Department of Housing and Community DevelopmentThree Divisions Division of Financial Assistance Administers more than 20 programs awarding loans and grants to hundreds of local public agencies, private nonprofit and for-profit housing developers, and service providers every year. This money supports the construction, acquisition, rehabilitation and preservation of affordable rental and ownership housing, child care facilities, homeless shelters and transitional housing, public facilities and infrastructure, and the development of jobs for low income workers. Division of Housing Policy Development Provides leadership, policies and programs to preserve and expand safe and affordable housing opportunities and promotes strong communities for all Californians. Division of Codes and Standards Administers the following seven programs: 20
California Department of Housing and Community DevelopmentOccupational Licensing Enforces State laws and regulations governing the sale or lease of manufactured homes, mobilehomes, and/or commercial coaches, including the licensing of manufacturers, distributors, dealers, and salespersons. The program also performs functions on behalf of the Mobilehome Ombudsman related to investigating and resolving consumer complaints pertaining to manufactured housing. Registration and Titling Maintains title and registration records and collects fees and taxes on manufactured homes, mobilehomes, commercial modulars, floating homes, and truck campers.
California Department of Housing and Community DevelopmentFactory Built Housing Promotes preemptive regulations establishing construction standards for factory-built homes and factory-built building components manufactured for sale or use within the State. Inspections are conducted and complying homes or components are issued a Department Insignia of Approval. Manufactured Housing Assists with the development and enforcement of preemptive federal and state regulations establishing minimum design and construction standards for manufactured homes, multi-unit manufactured housing, commercial coaches and special purpose commercial coaches sold, offered for sale, rented, or leased within the State. Inspections are conducted and the Department Insignias of Approval are issued to indicate compliance.
California Department of Housing and Community DevelopmentMobilehome Parks Promulgates preemptive statewide regulations for the construction, use, maintenance and occupancy of all privately-owned mobilehome and special occupancy parks in the State, as well as the installation of manufactured homes and mobilehomes both in and outside of parks. Directly, or through local governments, inspects and issues permits for park operation. Employee Housing Program Promulgates statewide regulations for the maintenance, use, and occupancy of privately-owned and operated employee housing facilities providing housing for five or more employees to assure their health, safety, and general welfare. Directly, or through local governments, inspects and issues permits for facility operation.
California Department of Housing and Community DevelopmentState Housing Law The SHL was enacted to protect the health, safety and general welfare of the public and occupants of dwelling units in the State of California. Under this authority, HCD promulgates building standards and regulations to ensure that hotels, motel, apartments, single-family dwellings, and other residential buildings are constructed and maintained in compliance with the model building codes and other provisions of State law.

California Green Building Standards CodeOverview
The Code Of Hammurabi The Code Of Hammurabi (1760 BC) contained 282 laws including some which covered building construction. If a builder build a house for some one, and does not construct it properly, and the house which he built fall in and kill its owner, then that builder shall be put to death. If it ruin goods, he shall make compensation for all that has been ruined, and inasmuch as he did not construct properly this house which he built and it fell, he shall re-erect the house from his own means. If a builder build a house for some one, even though he has not yet completed it; if then the walls seem toppling, the builder must make the walls solid from his own means.
What is CALGreen It is a statewide mandatory construction codeIt is not the same as a rating system or point based program It is statutorily enforced by local enforcing agencies It does not require outside inspection, review or certification by any entity other than the enforcing agencies It preserves local ability to make enhancements or modifications A word about comparisons and confusion Chapter 1, Administration Adopting state agency authorities Local amendments based on findings of climate Chapter 7, Installer and Special Inspector Qualifications Inspection and special inspection like other parts of Title 24 Documentation of compliance Chapter 8, Forms and Worksheets Sample forms for construction waste management plans Water use worksheets More compliance forms will be added Application checklist Mandatory provisions Provisions required for compliance with tiers 28

California Department of Housing and Community DevelopmentAppendix A4 – Residential Voluntary Measures 83
California Department of Housing and Community DevelopmentAppendix A4. The appendix was developed in response to numerous stakeholders requesting a statewide and consistent option to enhance the level of construction beyond the CALGreen minimum level. Tier based which go beyond the code minimum. Developed a checklist which can be used which can be used to select an manage the tiers. Included a sample resolution that may be used during the local adoption process. 84
California Department of Housing and Community DevelopmentTier 1 and Tier 2 Scope The measures contained in the appendix are not mandatory unless adopted by a city, county, or city and county.
