EAc1: Optimize Energy Performance

The Intent of this credit is to increase the level of energy efficiency in the building.
Requirements: There are 3 options to achieve points for this credit.  The first option is for a whole building energy simulation and there are 1-10 points available, depending on what level of performance your building achieves.  The 2nd option is […]

EAp3: Fundamental Refrigerant Management

Intent: Minimize ozone depleting chemicals
Requirements: No CFC based refrigerants in new buildings; CFC phase out in existing buildings
There are no Calculations or Exemplary Performance points available for this credit.  The documentation is part of the Design Submittal.

EAp2: Minimum Energy Performance

The Intent of this credit is to set a minimum performance level for energy systems.
Requirements: The project must comply with: ASHRAE/IESNA Standard 90.1-2004
There are a few calculations required for this credit, no Exemplary Performance points available, and the documentation is part of the Design Submittal.

EAp1: Fundamental Commissioning of the Building Energy Systems

The Intent of this credit is to make sure that the building’s energy systems are installed correctly and performing to the owner’s, design, and construction requirements.
Requirements: There are 6 required items in order to achieve this credit:
1. Designate a Commissioning Authority (CxA) to lead the completion of the Commissioning process.
2. The owner […]

Energy and Atmosphere: Overview

Today, buildings cause large amount of pollution through their energy consumption.  Buildings consume about 68% of the electricity generated in the United States.  This electricity is not usually produced by “green” resources - most of the electricity is generated from using fossil fuels which further deplete our source of limited fossil fuels and also add […]

WEc3.2: Water Use Reduction - 30% Reduction

Intent: Maximize efficiency of water systems to reduce the amount of water needed from the utility.
Requirements: The building must use 30% less water than the calculated baseline (not including irrigation) in order to achieve this credit.  The baseline is calculated after meeting the Energy Policy Act of 1992.
Approach: Employ various strategies, including dry fixtures such […]

WEc3.1: Water Use Reduction - 20% Reduction

Intent: Maximize efficiency of water systems to reduce the amount of water needed from the utility.
Requirements: The building must use 20% less water than the calculated baseline (not including irrigation) in order to achieve this credit.  The baseline is calculated after meeting the Energy Policy Act of 1992.

WEc2: Innovative Wastewater Technologies

The Intent of this credit is to lower the amount of wastewater generated by buildings.
Requirements: Option 1 - Reduce potable water use for sewage conveyance by 50%. Option 2 - Treat 50% of the wastewater on-site and use or infiltrated on-site.
There are extensive Calculations that must completed with the Design Submittal. There is […]

WEc1.2: Water Efficient Landscaping - No Potable Water Use or No Irrigation

The Intent of this credit is to completely eliminate the use of potable water in landscaping purposes.
Requirements: The requirements of this credit is pretty obvious - not use any potable water at all for landscaping or irrigation purposes.
Approach: Select plant species that use less water or need no irrigation at all, install efficient irrigation such […]
