Energy and Atmosphere

LEED Category: Energy & Atmosphere

EA Credit 1: Optimize Energy Performance
LEED Credit: 1-19 points

Intent: To achieve increasing levels of energy performance beyond the prerequisite standard to reduce environmental and economic impacts associated with excessive energy use.

Select 1 of the 3 compliance path options.

OPTION 1: Whole Building Energy simulation (1-19 Points)
Demonstrate a percentage improvement in the proposed building performance rating compared with the baseline building performance rating per ANSI/ASHRAE/IESNA Standard 90.1-2007 (without amendments), as demonstrated by a whole building project simulation using the Building Performance Rating Method in Appendix G of the Standard*.

OPTION 2: Prescriptive Compliance Path: ASHRAE Advanced Energy Design Guide (1 point)
Comply with the prescriptive measures of the ASHRAE Advanced Energy Design Guide, in the climate zone where the building is located, for buildings less than 20,000 SF and small warehouses less than 50,000 SF.

OPTION 3: Prescriptive Compliance Path: advanced Buildings™ Core Performance™ Guide (1–3 points)
Comply with the prescriptive measures in the Advanced Buildings™ Core Performance™ Guide developed by the New Buildings Institute. The building must be less than 100,000 square feet. Must comply with Section 1 and Section 2 of the Core Performance Guide. Health care, warehouse and laboratory projects are excluded.

JEB Contribution:

JE Berkowitz WinduoTM insulating glass units contribute to the LEED certification of your project.  JEB offers a wide range of products that can be paired with our WinduoTM units to help attain credits towards LEED certification. For the lowest Solar Heat Gain Coefficient (SHGC) performance* select clear, tinted or pyrolitic spectrally glasses paired with high performance Low-E products: PPG* Solarban® products; GuardianSunguard® products and Pilkington Energy Advantage.

JEB can support the project design to achieve maximum energy efficiency. We can configure products in our insulating glass units to meet design, orientation, and performance challenges. This includes utilizing warm edge spacer technology to improve overall U-Value and Condensation Resistance Factor (CRF) and argon gas fill, along with high performance Low E coatings, reflectively selective coatings, and tinted substrates, to support several climate zone criterions.
