Term
EA Credit 1.3 Optimize Energy Performance: HVAC
Definition

Meet e-benchmark requirements for HVAC and zone spaces accordingly OR reduce energy use of HVAC by 15% or 30% of the basline standard set by ANSI/ASHRAE/IESNA.

Prescriptive Performance

BASELINE

1-2 PTS

Term
EA Credit 1.3 Intent
Definition
Achieve increasing levels of energy conservation beyond the prerequisite standard to reduce environmental impacts associated with excessive energy use.
Term

HVAC Optimize Energy Performance

Opt A

Definition

Equipment Efficiency

 

Appropriate Zoning and Controls:

  • Solar Exposure
  • Interior spaces separately zoned
  • Private offices & specialty occupancies must have active controls capable of sening space us and modulating HVAC system in response to space demand
Term

HVAC Optimize Energy Performance

Opt B

Definition
  • Demonstrate that HVAC system component performance criteria used for tenant space are 15% better than a system that is in minimum compliance with 90.1 (1 POINT)
  • Demonstratve that the above is 30% better than 90.1 (2POINTS)
Term

Provide a narrative description of the HVAC system serving the tenant space as well as a description of the building level system.  Plans and specs shouldhave an HVAC equipment schedule and ___________________________.

Definition
plans showing the equipment within the space.
Term
E-benchmark
Definition
it is offered as a prescriptive approach where the ASHRAE/IENSA Section 11 is performance based.
Term

The major difference btw Opt A & Opt  B is that

the minimum equipment efficiency requirements in OPT A are more stringent than the minimum requirements in 90.1
Term
The second part of Option A is ____________ approach to the zoning and controls for commercial interior projects.
Definition
a prescriptive
Term
Every solar expose must have a

Term
Each side of a rectangular building with fenestration should be
Definition
zoned separately
Term
Interior ________ are another source of solar exposure and may warrant a separate zone as well.
