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

  2. 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

  3. ASHRAE Standard 90.1-2010 Goal: 30% improvement in stringency over Standard 90.1-2004 3

  4. 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

  5. Non-benchmark Building: High-rise Apartment 90.1 Simulation - Prototype Buildings McGraw-Hill Construction Data by Building Type HVAC system: Water-source heat pump system Fluid cooler and boiler PNNL report on construction weights: http://www.pnl.gov/main/publications/external/technical_reports/PNNL-19116.pdf 5

  6. 90.1 Simulation - Representative Climate Cities 6

  7. Progress Indicator - Overview • To measure progress toward the 30% improvement goal in Standard 90.1-2010 • Baseline is 90.1-2004 prototypes • Incorporate the published and BOD-approved addenda to all 16 prototype buildings • Apply in all 17 climate zones • Update PI and report to SSPC 90.1 at each quarterly meeting • Assign final construction weights to each prototype by climate zone • National weighted-average EUI and energy cost for each prototype • National weighted energy and cost saving percentage • Results are preliminary 7

  8. Progress Indicator - Addenda • 44 addenda to 2004 • 44 approved addenda to 2007 (through Jan 1, 2010) • 17 addenda pending for BOG approval in Orlando meeting • 3 addenda have been modeled in Jan2010 PI 8
