ASHRAE Standard 90.1 andModel Codes
  • ASHRAE Standard 90.1 is adopted by
  • National Fire Protection Association by reference
  • International Code Council (2009)(International
    Energy Conservation Code)
  • Chapter 5 Commercial Energy Code
  • Comply with 90.1-2007 or
  • Comply with the rest of Chapter 5

4
ASHRAE Standard 90.1 andUSGBC, LEED-2009 (v3)
  • EAp2 Minimum energy performance
  • Comply with 90.1-2007
  • Mandatory provisions of 90.1-2007 and
  • Prescriptive requirements of 90.1-2007 or Energy
    Cost Budget method of 90.1-2007 and
  • 10 improvement over 90.1-2007
  • Two prescriptive methods allowed (including
    AEDGs)
  • EAc1 Optimize energy performance
  • 1 point for 12 savings
  • 3 points for 16 savings
  • Up to 19 points (out of 100)

5
ASHRAE Standard 90.1-2007Purpose
Provide minimum requirements for the
energy-efficient design of buildings except
low-rise residential buildings
6
ASHRAE Standard 90.1-2007Scope
  • New buildings and their systems
  • New portions of buildingsand their systems
  • New systems and equipment in existing buildings

7
ASHRAE Standard 90.1-2007Exclusions
  • Low-rise residential buildings
  • ASHRAE Standard 90.2 covers low-rise(3 stories
    or less)
  • Buildings that do not use either electricity or
    fossil fuel
  • Equipment and portions of building systems that
    use energy primarily to provide for industrial,
    manufacturing, or commercial processes

8
ASHRAE Standard 90.1-2007Sections
  • Section 1 Purpose
  • Section 2 Scope
  • Section 3 Definitions, Abbreviations, and
    Acronyms

SSPC 90.1 Work Plan(unanimous June 2007)
  • Goal A 2010 standard that results in 30 total
    energy cost savings improvement compared to
    Standard 90.1-2004.
  • Measurement is aggregated, may not be met for
    every building in every location
  • 90.1-2010 90.1-2007 All IES and ASHRAE BOD
    approved addenda

11
How is 90.1 Updated?Through Addenda
  • Prior to public review
  • Change proposed
  • Subcommittee(s) develop drafts
  • SSPC discusses drafts
  • SSPC votes for public review and publication
  • SPLS and IES vote for public review and
    publication
  • BOD - TPS changes
  • Public review
  • Announced
  • Comments made
  • Comment responses voted on
  • If changes made, another PR voted on
  • Commenters reply
  • If resolved, addendum moves forward
  • If unresolved SSPC must revote with that knowledge

12
Where have addenda come from?
  • You
  • Other publications
  • Advanced Energy Design Guides
  • California Title 24
  • ASHRAE Standard 189.1
  • TCs
  • Stakeholders (working groups)
  • Energy conscious owners
  • SSPC 90.1 volunteers
  • 4 meetings per year(3-4 days each, 8 am 9 pm)
  • Additional web meetings
  • Monthly (or more often) conference calls

13
SSPC 90.1 Accomplishments06/2007 through

18
ASHRAE Standard 90.1-2010 (AQ)Purpose
To establish the minimum energy efficiency
requirements of buildings, other than low rise
residential buildings, for 1. design,
construction, and a plan for operation and
maintenance, and 2. utilization of on-site,
renewable energy resources
19
ASHRAE Standard 90.1-2010 (AQ)Scope
  • new buildings and their systems
  • new portions of buildings and their systems
  • new systems and equipment in existing buildings
  • new equipment or building systems specifically
    identified in the standard that are part of
    industrial or manufacturing processes

20
ASHRAE Standard 90.1-2010 (AQ)Does not apply to
  • a. single-family houses, multi-family structures
    of three stories or fewer above grade,
    manufactured houses (mobile homes), and
    manufactured houses (modular), or
  • b. buildings that use neither electricity nor
    fossil fuel

21

90.1 Progress Indicator Information
  • As of June 29, 2010
  • XX.X energy savings compared to 90.1-2004
    assuming same ventilation rate
  • YY.Y energy savings compared to 90.1-2004
    assuming updated Standard 62.1 ventilation rates

Stay tuned for the 1100 SessionBing Liu and
Steve Skalko
23
Future Addenda
  • Open to your suggestions through the Continuous
    Maintenance Proposal process
  • All meetings open to the public
  • Hard working members are welcome

24
Remember
  • Minimum standards define the worst buildings
    allowed
  • Increased stringency in minimum standards is
  • Possible
  • Being done via a public consensus process
  • An important step on the march to net-zero energy
    use intensity for some buildings
