Track: Standards, Guidelines and Codes
Sponsor: 7.6 Building Energy Performance, SSPC 100 Energy Efficiency in Existing Buildings
Chair: Joseph Firrantello, Ph.D., P.E., Member, Envinity, Inc., State College, PA
ASHRAE Standard 100 has undergone significant updates compared to the 2007 version of the standard, including new target tables in the 2015 version and additional compliance options in addendum b. This session summarizes new compliance requirements and options as well as approaches to facilitate international application of the standard, including climate zone information and target table development methods. Progress on possible enhancements to the underlying energy use index methodology in the next version of standard is highlighted.
1. Targets and Climates for International Application of Standard 100
Glenn Friedman, P.E., Fellow ASHRAE, Taylor Engineering, Alameda, CA
Most of the energy audit and provisions of Standard 100 can be applied around the world. However, the new target tables and climate zones are based on US information that may not be as useful for application in other countries. This presentation describes efforts to develop a methodology for determining targets for different countries, starting with Canada and broadening to Europe and the Middle East as well as Asia. Options for addressing climate zone variations as well as building categories will be reviewed.
2. New Compliance Options for Individual Users of ASHRAE Standard 100
Neil P. Leslie, P.E., Member, Gas Technology Institute, Des Plaines, IL
ASHRAE Standard 100-2015 Addendum b adds an alternative compliance path for users by providing normative primary energy EUI target tables in Sections 7 and 10 and Normative Appendix A of the standard. Along with these primary energy EUI target tables, site electricity and fossil fuel use target tables are also included for authorities having jurisdiction that prefer to use locally derived primary energy conversion factors for their primary energy EUI target calculation. This presentation provides details on derivation of these new primary energy EUI tables. Various options available to individual users for compliance with the standard are also illustrated.
3. Alternative Expressions of Performance for ASHRAE Standard 100: Is EUI Enough or Does It Need Help?
Dennis Landsberg, Ph.D., P.E., BEAP, Fellow Life Member, L&S Energy Services, Inc., Clifton Park, NY
Energy Utilization Index (EUI), typically measured in Btu per square foot per year, is the metric often used to characterize building energy efficiency, even though it is an energy performance metric. Among other issues with EUI, the energy use of some building types may not be strongly correlated with floor area, and high rise buildings may have different EUIs than low rise buildings with the same energy efficient construction characteristics. This presentation highlights ongoing activities within SSPC 100 to explore options that may provide better correlation with the energy efficiency of building systems than the current EUI metric.
