Energy Standards
There are four ASHRAE standards that affect
energy use in buildings: Standard 90.1,
Standard 90.2, Standard 100 and Standard
189.
Standard 90.1
Energy Efficient Design of New
Buildings covers all buildings except low-rise
residential for new design and build. It has
been used for all buildings in the past due to
the lack of detail in Standard 100.
Standard 90.2 Energy Efficient Desin of New
Low-Rise Buildings covers low-rise residential
buildings and has lacked detail in the past.
Standard 100 Energy Efficiency in Existing
Buildings is the energy standard for existing
buildings including residential. It was revised
in 2012 to include compliance requirements,
energy use analysis methods and energy
targets, operation and maintenance and
energy audit requirements for existing
buildings for energy efficiency. There is also
an extensive list of Energy Efficiency
Measures that can be incorporated into
existing buildings for energy efficiency.
Standard 189
Design of High-Performance
Green Buildings except Low-Rise Residential
Buildings – developed in conjunction with the
US Green Buildings Council that goes beyond
the requirements of Standard 90.1 for “green”
buildings.
The standards are used as the basis for many
federal, state and local jurisdictions as the
energy code. If a state does not use the
ASHRAE standards for the basis of the codes,
they will use the International Energy Code
Council (IECC) code.
In addition to the standards, ASHRAE has
developed a series of publications designed to
provide recommendations for achieving
energy savings over the minimum code
requirements of Standard 90.1 The guides
were developed in collaboration with The
American Institute of Architects (AIA), the
Illuminating Engineering Society of North
America (IES), the US Green Building Council
(USGBC) and the U.S. Dept of Energy (DOE).
All guides are free for download at the
ASHRAE website.
