the Energy Efficiency Standards for Residential
and Nonresidential Buildings were established in
1978 response to a legislative mandate to
reduce California's energy consumption new
standards were adopted by the Commission in 2005
as mandated by Assembly Bill 970 to reduce
California's electricity demand
3

• energy efficiency standards are important and
  necessary for Californias energy future
• reduces energy costs
• increases reliability and availability of
  electricity
• improves building occupant comfort reduces
  impacts to the environment

4
changes in 2001 (following the electricity
crisis) reduced electricity demand by about 150
megawatts (MW) each year the 2005 standards
were expected to reduce electric demand by
another 180 MW each year
5

• changes to the Standards occur periodically to
  account for improvements in
• conservation technologies
• cost of fuels
• energy-conserving strategies
• improved capabilities in analyzing building
  energy performance
• modifications are also made to further improve
  compliance and enforcement

6

• mandatory measures require
• minimum ceiling, wall, and raised floor
  insulation
• minimum HVAC (heating, ventilating and air
  conditioning) and water heating equipment
  efficiencies
• other requirementslighting standards

7
energy use depends partly on climate conditions,
which differ throughout the state  to
standardize calculations and to provide a basis
for presenting the criteria, the Energy
Commission has established 16 climate zones used
with both the low-rise residential and the
nonresidential standards
8

• documentation of the California Building Code is
  required to be submitted prior to issuing
  building permits
• new residential building
• adding new conditioned floor area to an existing
  building
