Energy Policy Act of 2005
The Energy Policy Act of 2005 addresses energy efficiency; renewable energy requirements; oil, natural gas
and coal; alternative-fuel use; tribal energy, nuclear security; vehicles and vehicle fuels; hydropower and
geothermal energy; and climate change technology. The act provides revised annual energy reduction goals
(two percent per year beginning in 2006), revised renewable energy purchase goals, federal procurement of
Energy Star or Federal Energy Management Program designated products, federal green building standards,
and fuel cell vehicle and hydrogen energy system research and demonstration.
Energy Independence and Security Act of 2007 (EISA)
EISA was signed into law on December 19, 2007. The objectives for EISA are to move the United States
toward greater energy independence and security, increase the production of clean renewable fuels, protect
consumers, increase product, building and vehicle efficiency, promote greenhouse gas (GHG) research,
improve the energy efficiency of the federal government, and improve vehicle fuel economy.
The renewable fuel standard in EISA established appliance energy efficiency standards for boilers,
dehumidifiers, dishwashers, clothes washers, external power supplies, commercial walk-in coolers and
freezers; federal buildings; lighting energy efficiency standards for general service incandescent lighting in
2012; and standards for industrial electric motor efficiency.
2.2.2 State Regulations
California Building Energy Efficiency Standards: Title 24
California established statewide building energy efficiency standards following legislative action. The
legislation required the standards to be cost-effective based on building life cycle and to include both
prescriptive and performance-based approaches. The 2005 Building Energy Efficiency Standards were first
adopted in November 2003 and took effect October 1, 2005. Subsequently the standards have undergone
various updates including 2013, 2016, 2019, and 2020.
The 2013 Building Energy Efficiency Standards went into effect on July 1, 2014. The 2016 standards, which
went into effect on January 1, 2017 and continue to improve upon the current 2013 Standards for new
construction of, and additions and alterations to, residential and nonresidential buildings. The 2019 Building
Energy Efficiency Standards improve upon the 2016 Energy Standards for new construction of, and
additions and alterations to, residential and nonresidential buildings. Buildings permitted on or after January
1, 2020, must comply with the 2019 Standards. The California Energy Commission updates the standards
every three years.
The 2022 Building Energy Efficiency Standards (Energy Code) will improve upon the 2019 Energy Code for
new construction of, and additions and alterations to, residential and nonresidential buildings.
Assembly Bill 1575 (AB 1575)
In 1975, largely in response to the oil crisis of the 1970s, the California State Legislature adopted Assembly
Bill (AB) 1575, which created the California Energy Commission (CEC). The statutory mission of the CEC is
to forecast future energy needs, license thermal power plants of 50 megawatts or larger, develop energy
technologies and renewable energy resources, plan for and direct state responses to energy emergencies,
and, perhaps most importantly, promote energy efficiency through the adoption and enforcement of
appliance and building energy efficiency standards. AB 1575 also amended Public Resources Code Section
21100(b)(3) to require Environmental Impact Reports (EIRs) to consider the wasteful, inefficient, and
