ASHRAE Standard 90.1-2013

Aiming at 50% Energy SavingsFor 90.1-2013

Background on Standard 90.1- 2013 The “Goals” for 2013 Changes under consideration The Future

ASHRAE Standard 90.1-2013

90.1-2010 – 2013

• ASHRAE Technology Committee - Ad-Hoc Committee on Energy Targets – June 2010 Promote EUI as measurement Encourage use of ASHRAE Stds 62.1 & 55 SSPC 90.1 responsible for our energy targets Standard 90.1 IS NOT the foundation for

meeting Vision 2020 or NZEB AEDGs are mechanism for NZEB

90.1-2010 – 2013 & Future

• Wholistic systems designs• Systems Design and

subsystems effects

90.1-2010 – Future

• Alternate Performance Methodologies Determine “base minimum” using whole

building designs Explore regional utility rates Explore time/demand rates Consider water use and rates Explore criteria metrics other than cost

savings (e.g. system efficiencies) Address renewables (site based & grid based) Use AEDG format for the 90.1 standard
