EA Credit 1 – Optimize Energy Performance
LEED NC – Energy and Atmosphere Credit 1.1 – Optimize Energy Performance
LEED CI – Energy and Atmosphere Credit 1.1
LEED NC & LEED CI Intent: Achieve increasing levels of energy performance above the baseline standard to reduce environmental
and economic impacts associated with excessive energy use.
LEED NC Requirement: Demonstrate a percentage improvement in the proposed building performance rating compared to the baseline
building performance rating per ASHRAE/IESNA Standard 90.1-2004 OR Comply with the prescriptive measures of the ASHRAE Advanced
Energy Design Guide for Small Office Buildings 2004. OR Comply with the Basic Criteria and Prescriptive Measures of the Advanced
Buildings Benchmark™ Version 1.1.
LEED CI Requirement: Reduce connected lighting power density below that allowed by
ASHRAE/IESNA Standard 90.1-2004.
Armstrong Ceiling Systems Contribution:
To aid in reducing lighting power density which lowers energy and maintenance costs, Armstrong High Light Reflectance ceilings
and systems provide the same level of illuminance with fewer luminaries. This will assist in reducing lighting and HVAC energy
costs up to 25% in new or existing building structures where a High Light Reflectance ceiling is installed along with indirect
lighting. Also steps to reduce the number of fixtures and reduce the wattage of lamps should be taken. The number of LEED
credits awarded for such improvements are different for new and existing building structures. The TechZone™ Ceiling System combines High Light Reflectance ceilings with indirect lighting which contributes to EA Credit 1. Contact TechLine at 877-276-7876 for our independent study, “Energy and Environmental Benefits of High Light Reflectance Ceilings.” A suspended ceiling contributes to lower first time and operating cost for a building.
