More information can be found at IES is the oldest and largest educational and scientific society in North America devoted to lighting. Through research, standards writing, publishing, certification and continuing education, ASHRAE shapes tomorrow’s built environment today. The Society and its more than 57,000 members worldwide focus on building systems, energy efficiency, indoor air quality, refrigeration and sustainability. removed ventilation optimization exception for energy recovery ventilatorĪSHRAE, founded in 1894, is a global society advancing human well-being through sustainable technology for the built environment.eliminated computer room economizer threshold.required high efficiency dwelling unit lighting.improved hotel/motel guest room control.included service factor in heat rejection VFD threshold.reduced exterior and interior lighting allowances.raised minimum exhaust air energy recovery threshold.reduced heat rejection variable frequency drive (VFD) threshold.added domestic hot water branch insulation.updated transformer efficiency requirements.established minimum chilled water systems coil selection Delta T.improved coiling door air leakage requirements.improved window U-factor and solar heat gain coefficient.updated controls for emergency lighting.The energy reduction calculation was achieved through more than 120 addenda incorporated in the standard related to changes to requirements. Sixteen different building prototypes were modeled in 17 different climate locations for a total of 272 building types in various climate zones that were incorporated into this analysis. These figures include energy use and cost from the whole building energy consumptions including plug and process loads. On a nationally aggregated level, building-type energy savings range from 11.9% (fast food restaurants) to 48.6% (schools) and energy-cost savings from 15.3% (large offices) to 49.8% (schools). We are proud of the dedicated members of the Lighting Subcommittee and the Standard 90.1 committee and their significant contribution to the energy savings achieved by the 2016 version.” 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, says. 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.”
#ASHRAE 90.1 2016 WINDOW U FACTOR UPDATE#
“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,” says Tim Wentz, ASHRAE President. “Each year the challenge grows as technology becomes more efficient. PNNL’s analysis shows for the whole building energy consumptions, national aggregated site energy savings are 34.1% and energy cost savings are 34.2% when compared to the 2004 standard. These results are considered preliminary and are expected to be deemed final in October 2017 when DOE publishes its final determination. PNNL conducted the energy savings analysis, using the 2004 standard as baseline. ANSI/ASHRAE/IES Standard 90.1-2016, Energy Efficiency Standard for Buildings Except Low-Rise Residential Buildings, was published in October 2016. Department of Energy (DOE) Building Energy Codes Program.Īn update on the preliminary results of the 90.1-2016 progress indicator report was made at the recent 2017 ASHRAE Winter Conference. More than 30% of energy savings can be achieved using the 2016 version of Standard 90.1, according to recent analysis conducted by Pacific Northwest National Laboratories (PNNL) in support of the U.S.
