The New York State Energy Research and
Development Authority is a public benefit corporation established by the New York State Legislature in 1975. NYSERDA’s mission is to address the State’s energy and environmental challenges while improving the economy.
NYSERDA’s Mission:
NYSERDA strives to encourage decisions
involving energy that drive positive environmental
and economic results.
NYSERDA’s New Construction Program Objective:
• Transform the way buildings are designed and built
Services:
• Financial incentives to offset added costs associated with more energy-efficient equipment and systems
• Energy and Green Building Technical Assistance
• Commissioning
• LEED, Executive Order 111, NYS Green Building Tax Credit
Charrette Participants
A forum where every team member is
encouraged to cross fertilize with all others
in order to identify solutions to problems
that may relate to, but are not typically
addressed by any one team member’s
specialty. The objective is to have every
member of the design team understand the
issues that the other members need to
address. Results in a more thorough and
integrated solution
Design Charrette Essentials
1. Establish Project Goals
Design an Energy Efficient Building
Provide a Day lit Building
LEED ® Certification
2. Define Project Goals
Energy Efficiency = 20% better than ASHRAE
Day lit = Achieve a 2% Daylight factor
LEED® = Gold
3. Establish Decision Making Parameters
20% better than ASHRAE = EEMS with an ROI of > 20%
Day lit = Saves Energy & Comfortable Environment
LEED® = Pursue credits with multiple benefits
Goal: Design an Energy Efficient
Building 20% better than ASHRAE
Whole Building Approach:
•Capital Incentives
•Technical Assistance

– Equipment efficiency ratings
– Building loads:
• Envelope materials, insulation
• Window efficiency and % of total area
• Internal loads: lighting, appliances
• Required ventilation: how much outdoor air must be
used
– System layout: shorter pipe runs, shorter duct runs,
fewer bends
– Control strategies: unoccupied modes, automatic
lighting, free cooling
What Determines Building
Performance?
Reduce the loads first – lighting selection,
daylighting
Choose high efficiency equipment
Use energy saving technologies –
VSD, occupancy sensors
Take advantage of free energy – waste heat
recovery, economizers, night precooling

The integrated design process is the key to
producing high performance green buildings
within budget.
Green Building Charrette Objectives:
1. Gain an understanding of the process required to
realize high performance LEED® goals.
2. Establish preliminary LEED ® performance goals.
3. Familiarize participants with the importance of this
approach.
4. Identify design concepts and strategies.
5. Assign Champions.
6. Establish next steps.
LEED ® Sustainable SitesCredit 7.1 – Heat Island Effect: Non-Roof
• Intent: Reduce heat islands (thermal gradient differences
between developed and undeveloped areas) to minimize on
microclimate and human and wildlife habitat.
LEED ® Sustainable SitesCredit 7.1 – Heat Island Effect: Non-Roof
