International. According to recent analysis by Pacific Northwest National Laboratories (PNNL) with support from the U.S. Department of Energy's (DOE) Building Energy Code Program, more than 30% energy savings can be achieved using the 2016 version of Standard 90.1.
An update of the preliminary results of the 90.1-2016 indicators of achievement report was made at the recent ASHRAE Winter Conference held in 2017. The ANSI/ASHRAE/IES 90.1-2016 Standard, Energy Efficiency Standard for Buildings Except Low-Rise Residential Buildings, was published in October 2016.
PNNL carried out the energy saving analysis, using the 2004 standard as the baseline. These results are considered preliminary and are expected to be considered final in October 2017 when the DOE publishes its final determination.
The NLP analysis shows for all building energy consumptions, the national aggregate energy savings on site is 34.1% and the energy cost savings is 34.2%, compared to the 2004 standard.
Nationally, energy savings from type buildings range from 11.9% (fast food restaurants) to 48.6% (schools) and energy savings from 15.3% (large offices) to 49.8% (schools). These figures include the energy use and cost of energy consumption of the entire building.
Sixteen different building prototypes were modeled at 17 different climate locations for a total of 272 building types in various climate zones that were incorporated into this analysis.
