 Energy & Atmosphere Credit 1: Optimize Energy Performance

This credit is intended to increase levels of the building’s energy performance.

One option to earn points for this credit is to exceed a baseline building

performance rating per ASHRAE/IESNA (Illuminating Engineering Society of

North America) Standard 90.1-2004. A maximum of 10 points is attainable from

this credit, which would be awarded if a new building surpassed the

ASHRAE/IESNA Standard 90.1-2004 by 42% or 35% for an existing building.

Stimulations for a baseline model and the proposed project are necessary to

determine the amount that the building would exceed ASHRAE/IESNA 90.1-2004

requirements [73, p. 33-35].

 Energy & Atmosphere Credit 4: Enhanced Refrigerant Management

One point is available from this credit that requires either no refrigerants be used

or limits the use of refrigerants to those that minimize or eliminate the emission of

compounds that contribute to ozone depletion and global warming [73, p. 39-40].

Overall, a maximum of eleven points could be awarded under the LEED NC Version 2.2

rating system. Although, an additional point may be earned under the Innovation and Design

Process Credit 1: Innovation in Design, which rewards points for innovative performance not

specifically addressed by the LEED NC rating system [73, p. 77]. The LEED NC Version 2.2

rating system does not have a credit to reward for non-renewable on-site power generation or

designs that have equipment with low emissions or low sound levels, such as fuel cell systems.

These issues are presented as individual credits in the EPC Guide for Data Centers draft.

5.7.2 Obtainable LEED Points with Environmental Performance

Criteria Guide for Data Centers Draft

The following credits may be obtainable under the EPC Guide for Data Centers draft

when applying a fuel cell CHP system with absorption chillers to a data center.

 Sustainable Sites Credit 5.4: Site Development, Noise Impacts

This is a new credit to the NC Version 2.2 rating system. One point is available if

the sound level at the property line is at least 10% less than the locally mandated

requirement during normal and emergency operations of the data center. The

draft suggests adding retaining walls to decrease equipment sound levels.
