Fundamentals and Applications
Chair:
Wayne H. Stoppelmoor Jr., Schneider Electric
Technical Committee: 07.06 Building Energy Performance
Sponsor: SSPC 100
CoSponsor: 02.08 Building Environmental Impacts and Sustainability
Existing building renovations comprise 86% of annual construction cost in the United States. Improving the energy performance of existing buildings represents one of our greatest opportunities for a more sustainable future. This seminar provides information on new provisions in Standard 100-2015. The revised standard provides comprehensive and detailed descriptions of the processes and procedures for the retrofit of existing residential and commercial buildings to achieve greater energy efficiency. Development and application of newly developed energy targets for compliance will be described, along with detailed energy audit procedures included in the standard.
1 Key Objectives and Provisions of a Major Revision to ASHRAE's Existing Buildings Energy Efficiency Standard

Gordon V. R. Holness, P.E., Consulting Engineer |
Standard 100-2015 includes significant revisions to the 2006 version with the objective of becoming impactful and relevant as a code intended standard. The 2015 version provides greater guidance and a more comprehensive approach to the retrofit of existing buildings for increased energy efficiency. It sets specific Energy Targets based on performance compared to the 25th or 40th percentile of CBECS or RECS data by building type, climate zone, and building occupancy. It also includes an energy audit path for buildings without energy targets. This presentation summarizes the objectives and options for compliance with the updated requirements.
2 Development and Application of Target Tables in Standard 100

Terry Sharp, P.E., Oak Ridge National Laboratory |
EUI energy targets in Standard 100-2015 were derived from the 2003 CBECS and 2005 RECS databases, supplemented by energy modeling as necessary, for 53 building types in 16 U.S. climate zones. An analysis of CBECS data to investigate the impact of operating schedule by building type enabled development of “shift multipliers” that could be used to adjust building energy use intensities in commercial buildings. This presentation provides details on the development of the standard's energy target tables and shift multipliers, along with options for updating the tables based on the new CBECS database scheduled for publication in 2016.
3 The Energy Audit Path in Standard 100

Jim Kelsey, P.E., kW Engineering |
Standard 100-2015 includes energy audit requirements for buildings without targets and energy audit requirements for buildings that don’t meet their energy use intensity targets. The Standard also includes requirements for an Energy Management Plan, an Operation & Maintenance Plan, and addresses requirements for ongoing commissioning. This presentation will provide details on compliance with the Standard via the energy audit paths as well as helpful information for users in several informative annexes of the standard.
