1 Stephen V. Skalko, P.E. Chair SSPC 90. Aiming at 50% Energy Savings For ASHRAE Winter Meeting January 28, 203 AIA Objectives for the Session Develop basic understanding of different formats associated with energy codes for commercial buildings Understand how format impacts how and which criteria can be included in the code Learn how formats affect implementation and verification of compliance with those criteria Be conversant with the advantages and disadvantages of different formats based on code adoption mechanism -203 ASHRAE is a Registered Provider with The American Institute of Architects Continuing Education Systems. Credit earned on completion of this program will be reported to ASHRAE Records for AIA members. Certificates of Completion for non-aia members are available on request. This program is registered with the AIA/ASHRAE for continuing professional education. As such, it does not include content that may be deemed or construed to be an approval or endorsement by the AIA of any material of construction or any method or manner of handling, using, distributing, or dealing in any material or product. Questions related to specific materials, methods, and services will be addressed at the conclusion of this presentation PRESENTATION OBJECTIVES Background on Standard The Goals for 203 Changes under consideration The Future Revision Goals ASHRAE Technology Committee - Ad-Hoc Committee on Energy Targets June 200 Promote EUI as measurement Encourage use of ASHRAE Stds 62. & 55 SSPC 90. responsible for our energy targets Standard 90. IS NOT the foundation for meeting Vision 2020 or NZEB AEDGs are mechanism for NZEB Technically justified Simplicity Flexibility Enforceable
