Document OPR/ BOD, CxA to review
Cx Plan
Cx requirements in CD’s - general requirements
and divisions
Design Review prior to mid CD’s
Review contractor submittals
Verify installation and performance of systems
Systems manual
Verify Training requirements
Cx report
Review building within 10 months Documented as CxA in at least 2 buildings
Independent from design and CM but can be from the same firm (exempt if under 50k gsf)
May not be an employee of the design firm(s) (Enhanced Cx)
Report directly to the owner SYSTEMS HVAC&R and associated controls

Lighting and daylighting controls

*Additional Possibilities Reduced energy use
Lower operating costs
Fewer call backs
Better building documentation
Improved occupant productivity
Verification of systems performance
Obtain green certifications "Owners can achieve savings in operations of $4 over the first five years of occupancy as a direct result of every $1 invested in commissioning—an excellent return on investment." 2008. National Institute of Building Sciences. Bringing onto the team too late

Part 12 - Reference Standards Code Effective January 1, 2011 Mandatory requirements Commissioning for buildings over 10,000sf Sustainable design measures City or county can enact local ordinances
establishing more restrictive standards. Voluntary Measures Tier 1 Tier 2 Does CALGreen = LEED? *CALGreen requires projects to meet energy code (Title 24 Part 6). LEED requires minimum 10% better. CALGreen applies to every building in CA.
LEED, Build It Green and other rating systems apply to less than 1 percent of the built environment. "We believe green building rating systems and programs are both distinct and complementary to CALGreen."

health, safety and general welfare by enhancing the design and construction of buildings through the use of building concepts having a reduced negative impact or positive environmental impact and encouraging sustainable construction practices" CALGreen Section 101.2 CA Green Building Initiative - Executive Order S-20-04
Reduce grid-based electricity by 20% in state-owned buildings by 2015
Reduce associated greenhouse gas emissions Global Warming Solutions Act of 2006 - Assembly Bill 32
Reduce state green house gas (GHG) emissions to 1990 levels by 2020 Statewide Mandated Green Building Code Why? Even though it is not as stringent and may not be as technically enforced, the CalGreen code should have a much bigger impact.
