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)*
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)

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." [www.leedbuilding.org]
