Why a CalGreen Code?
n 2004: California Green Building Initiative (EO S-20-04): n 20% electricity reduction in state-owned buildings by 2015.
n 2006 - Global Warming Solutions Act (AB 32): n Reduce GHG emissions to 1990 levels by 2020.
n Buildings: 2nd largest contributor to GHG emissions.
n 2007 – Bills on green building standards in state legislature.
18
By the year 2035, three-quarters of the built environment will be new or renovated.

• State Housing LawThe 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.

DSA – Green Code for K-14 schools
• The DSA used the Building Standards Commission’s (BSC) Green Code as a basis to determine what provisions would apply to public schools and community colleges
• Additional vetting of proposals was done with the DSA Advisory Board’s Green Committee, CASH, and CHPS
• For an overview of the mandatory and voluntary provisions, see the Application Checklist DSA-SS in Chapter A5 appendix
• DSA-SS provisions do not have “tiers” for voluntary reach standards as shown in the BSC application checklist for commercial buildings
• Mandatory measures do not apply to every new construction or modernization project; see the Administration Chapter 1, Section 105 for specifics
