ANSI/ASHRAE/IES Standard 90.1-2016 -- Energy Standard for Buildings Except Low-Rise Residential Buildings (I-P Edition)

Product Code/ISBN: D-86274

Stay up-to-date and current with the energy efficiency standards from ASHRAE (American Society of Heating, Refrigeration, and Air Conditioning Engineers) and IES (Integrated Energy Systems) with the ANSI/ASHRAE/IES Standard 90.1-2016 – Energy Standard for Buildings Except Low-Rise Residential Buildings.  Since the last edition in 2013 there have been 125 addendas published and are all included in this version. 


“It is the overall goal of each version to create a consensus standard that saves energy and is technically feasible and cost effective…In addition, as a result of a strategic initiative begun in the 2013 cycle, the 2016 version has a new format that we believe will be easier for users, a new way of incorporation of reference material from other standards, starting with climate data, and a performance path for compliance that rewards designs for achieving energy cost levels above the standard minimum.” Stated Drake Erbe, the chair of the Standard 90.1 Committee, about the 2016 version:

 The 2016 version contains changes to the following sections:

  • Building envelopes now include requirements for Climate Zone 0, metal building roofs, walks, fenestration, opaque doors, and air leakage to overhead coiling doors.  The changes also include envelope verification needed for support of reduced air filtration.
  • Requirements for lighting now include dwelling units as well as modifications to lighting in parking areas, interior lighting power densities, and advanced lighting controls.
  • Mechanical  requirements are updated for elevator efficiency, DOAS, and chilled water plant metering.  Most of the changes in mechanical are not only new to the 2016 version, but have never been included in any previous versions and are available for the first time ever.
  • Appendix G now includes motor, refrigeration baselines, and elevators.  There are also changes to lighting controls, humidification systems, simulation of preheat coils, cooling towers, heat pump auxiliary heat, and economizer shutoff.
