ASHRAE 2010 Winter Conference January 24, 2010 Orlando, Florida Using the Benchmark Building Models for the Standard 90.1 Development Bing Liu, P.E., C.E.M. LEED AP Senior Research Engineer Pacific Northwest National Laboratory

ASHRAE Standard 90.1 Background Energy design standard for commercial and high-rise (> 3 stories) multi-family residential buildings Baseline of many above-code programs for commercial building energy efficiency, including AEDGs, Standard 189.1, and LEED Developed in an ANSI consensus process by ASHRAE and IESNA in a 3-year publication cycle. 2

4/21/2017 ASHRAE Standard 90.1-2010 Goal: 30% improvement in stringency over Standard 90.1-2004 Progress towards goal tracked by simulation of DOE Benchmark buildings with all approved and applicable addenda 3

PNNL’s Simulation Support to 90.1 Energy Saving Analyses Support subcommittees’ new proposals Develop the building load profiles for MSC Update the regression equations for ESC Progress Indicator Track the energy saving impacts during development of the 90.1-2010 in achieving the 30% goal DOE’s Determination Estimate the energy savings of 90.1-2007 and 90.1-2010 as part of DOE’s Determination Quantitative Analysis. 4
