Significant changes to the 2019 version include:
ASHRAE 90.1 2016 WINDOW U FACTOR MANUAL
Portal, a multiple-publication online tool that brings together the standard, User’s Manual guidance and tools. The energy standard can be viewed in ASHRAE’s online 90.1. For more than 35 years, Standard 90.1 has been a benchmark for commercial building energy codes for the United States and a key basis for codes and standards around the world. “This new version focuses on energy-saving measures which we hope will reward designs for achieving energy cost levels above the standard minimum and result in more efficient buildings and more innovative solutions.”įrom energy efficiency requirements for design and construction of new buildings and their systems to compliance criteria, the standard provides minimum requirements for energy-efficient design for most buildings. “The goal of the 2019 version of 90.1 was to provide clearer guidance for exceeding efficiency goals,” said Drake Erbe, Member ASHRAE, chair of the Standard 90.1 committee. The expanded, revised version of the energy standard focuses on energy-saving measures the Standard 90.1 committee hopes will help designers create more energy-efficient buildings. The newly updated ANSI/ASHRAE/IES Standard 90.1-2019, Energy Efficiency Standard for Buildings Except Low-Rise Residential Buildings, includes new and updated equipment efficiency requirement tables and a clearer compliance path for renewable energy treatment. The latest edition of ASHRAE’s most prolific energy standard includes more than 100 updates since the last edition was published in 2016.

Updated controls for emergency lighting.The energy-reduction calculation was achieved through more than 120 addenda related to changes to requirements. Sixteen building prototypes were modeled in 17 climate locations as part of the analysis. These figures include energy use and cost from whole-building energy consumption, including plug and process loads. On a nationally aggregated level, building-type energy savings range from 11.9 percent (fast-food restaurants) to 48.6 percent (schools), while energy-cost savings range from 15.3 percent (large offices) to 49.8 percent (schools). These baseline products were reevaluated and updated to reflect the market shift toward higher-efficiency lighting sources.” “Compliance with recommended light levels is verified using a database of luminaires.

“The Illuminating Engineering Society has actively engaged with ASHRAE since 1975, providing technical support and co-developing standards,” Mark Lien, IES industry-relations manager and liaison to the Standard 90.1 committee, said. That we continue to build upon the savings speaks to the ability of our industry to adapt and transform as those technologies change and more advanced technologies become more cost-effective.” “Each year, the challenge grows as technology becomes more efficient. “For more than 40 years, ASHRAE and IES members have strived to build upon the energy-savings measures in each update of Standard 90.1, most recently released in its 10th edition,” Tim Wentz, PE, FASHRAE, HBDP, ASHRAE president, said.
