ASHRAE announced the publication of a user's manual on the new, revised version of Standard 90.1 on the energy-efficient design of buildings; the standard includes new provisions on air barriers and other systems and technologies.
The ANSI/ASHRAE/IES standard provides minimum requirements for the energy-efficient design of buildings except low-rise residential buildings and contains 109 approved addenda since it was published in 2007.
“The new User’s Manual is a very useful resource because it helps guide practitioners by explaining the intent of provisions in the standard and how they apply to buildings through not only written word but also illustrations and example problems,” said Steve Skalko, chairman of the Standard 90.1 committee.
ASHRAE said the manual assists users in a variety of ways, including:
• application of new requirements in the standard regarding data centers;
• explanation of new lighting power-density requirements and application of revised lighting controls;
• application of new requirements for building envelopes including vestibules, continuous air barriers, skylights, daylighting controls, and the use of dynamic glazing;
• explanation of how to apply new HVAC requirements, including higher equipment efficiencies, energy-recovery provisions in more applications, economizers required in more climates, and smaller system sizes and more energy-conserving controls;
• changes to modeling requirements (e.g. for U.S. Green Building Council LEED® certification) that were clarified and expanded.
Originally developed in response to the energy crisis in the 1970s, Standard 90.1 has become the basis for building codes and the standard for building design and construction throughout the U.S., ASHRAE said.
The cost of the 90.1-2010 User’s Manual is $99 ($84, members).
