SECTION CREDITS
Energy & Atmosphere  
  Credit 1:
Optimize Energy Performance
INTENT  
  Achieve increasing levels of energy performance above the prerequisite standard to reduce environmental impacts associated with excessive energy use.  
    REQUIREMENT  
 
 
Reduce design energy cost compared to the energy cost budget for energy systems regulated by ASHRAE/IESNA Standard 90.1-1999 (without amendments), as demonstrated by a whole building simulation using the Energy Cost Budget Method described in Section 11 of the Standard. 
(25% - New buildings, 3 points)
 
  Credit 5:
Measurement & Verification
(Optional)
INTENT  
  Provide for the ongoing accountability and optimization of building energy and water consumption performance over time.  
    REQUIREMENT  
    Install continuous metering equipment for end-users:
Lighting systems
Motor loads
Chiller efficiency at variable loads
Cooling load
Air/water economizer and heat recovery cycles
Air distribution static pressure and ventilation air volume
Boiler efficiencies
Building-related process energy systems and equipment
Indoor water risers and outdoor irrigation systems
(1 point)*
 
Indoor Environmental Quality  
  Credit 1:
Carbon Dioxide (CO2)Monitoring
(Optional)
INTENT  
  Provide capacity for indoor air quality (IAQ) monitoring to help sustain long-term occupant comfort and well-being.  
    REQUIREMENT  
 
 
Install a permanent carbon dioxide (CO2) monitoring system that provides feedback on space ventilation performance in a form that affords operational adjustments.  Refer to the CO2 differential for all types of occupancy in accordance with ASHRAE 62-2001, Appendix D.
(1 point)*
 
  Credit 2:
Ventilation Effectiveness
INTENT  
  Provide for effective delivery and mixing of fresh air to support the safety, comfort and well-being of building occupants.  
    REQUIREMENT  
 
 
For mechanically ventilated buildings, design ventilation systems that result in an air change effectiveness (Eac) greater than or equal to 0.9 as determined by ASHRAE 129-1997.
(1 point)
 
  Credit 6.2:
Controllability of Systems
INTENT  
  Provide a high level of thermal, ventilation and lighting system control by individual occupants or specific groups in multi-occupant spaces to promote the productivity, comfort and well-being of building occupants.  
    REQUIREMENT  
 
 
Provide controls for each individual for airflow, temperature and lighting for at least 50% of the occupants in regularly occupied areas.
(1 point)
 
  Credit 7.1:
Thermal Comfort
Comply with ASHRAE 55-1992
INTENT  
  Provide a thermally comfortable environment that supports the productivity and well-being of building occupants.  
    REQUIREMENT  
 
 
Comply with ASHRAE Standard 55-1992, Addenda 1995, for thermal comfort standards including humidity control within established ranges per climate zone. 
(1 point)*
 
  Credit 7.2:
Thermal Comfort
Permanent Monitoring System
INTENT  
  Provide a thermally comfortable environment that supports the productivity and well-being of building occupants.  
    REQUIREMENT  
    Install a permanent temperature and humidity monitoring system configured to provide operators control over thermal comfort performance and the effectiveness of humidification and/or dehumidification systems in the building.
(1 point)*
 
Innovation & Design Process  
  Credit 1:
Innovation in Design
INTENT  
  To provide design teams and projects the opportunity to be awarded points for exceptional performance above the requirements set by LEED Green Building Rating System and/or innovative performance in Green Building categories not specifically addressed by the LEED Green Building Rating System.  
    REQUIREMENT  
    Identify the intent of the proposed innovation credit, the proposed requirement for compliance, the proposed submittals to demonstrate compliance, and the design approach (strategies) that might be used to meet the requirements.
(1 point)
 

*Per Argon recommendations

LEEDTM stands for Leadership in Energy and Environmental Design, a program of the U.S. Green Building Council.  The aim of the Council is to promote buildings that are environmentally responsible, profitable and healthy places to live and work.  The LEED Green Building Rating SystemTM evaluates environmental performance from a "whole building" perspective over a building's life cycle, providing a definitive standard for what constitutes a "green building."
