What it means to be green…
NYU Green Action Plan
• One of the nation’s largest wind-credit purchases (118 million kWh)
• The Next Generation of CoGeneration (CHP)
• Sustainability = Recycle, Re-use, Understand your impact on the environment
CoGeneration…The Next Generation is CHP
Combined Heat and Power Production (CHP)
• More Efficient• Clean Energy• Fuel Conservation
CHP is the simultaneous production of electricity and useful thermal energy (let’s learn more!)
“CHP can increase operational efficiency and decrease energy costs, while reducing emissions of greenhouse gases that contribute to
climate change.” U.S. Environmental Protection Agency (EPA)
Conventional Generation
30% of energy input (fuel) converted to energy output (electricity)
70% loss of energy (as heat) emitted to environment
CHP (turns the formula around by using the wasted heat)
70 to 90% of energy input (fuel) converted to energy output (electricity and heat)
10 to 30% loss of energy
Runs on natural gas, and sometimes low sulfur fuel
Conventional Generation
Fuel 100%
(Remote from thermal users)

CoGeneration at NYUCoGeneration at NYUCurrent CoGeneration Operation• 30 year old equipment (was good at the time)• Runs mainly on diesel fuel• Supplies electricity to 7 University buildings• By 2008, need the plant to be retired in order to meet environmental
code
NYU Decision to invest in CoGeneration/CHP• Large initial capital investment ($110 – 120 million)• Responsible investment because of immediate environmental benefits
and long-term financial benefits • Expand capacity to supply energy to 30 University buildings• Removal of University buildings from over-burdened ConEdison lines
If NOT CoGeneration/CHP• Was alternative to take current CoGen off-line and NOT replace with
new CoGen…but,• $60 million to take current plant off-line, reconnect buildings to
ConEdison lines and install local generators and fuel tanks to meet life safety and critical load emergency power requirements
• Similar construction impact but with very negative implications for the environment
• Machinery would need to be added (likely to rooftops) of University buildings
Environmental Benefits of NYU’s CoGeneration/CHP Plans

Particulate Matter 462 60 402 87%
* Emissions factors based on NYSERDA published data** Based on similar load capacity as new plant
Environmental Benefits
38% Reduction in CO2• CO2 seen as leading cause of global warming
83% Reduction in Regulated Pollutants• NOx – causes smog• SOx – causes acid rain• Carbon Monoxide
87% Reduction in Particulate Matter• Leading cause of asthma, particularly a problem
for children
NYU’s Planned CoGeneration/CHP Plant
is equivalent to…
NYU planting 7.8 million trees
NYU eliminating emissions from 5.8 million gallons of gas burned per year
Removing 10,000 cars from the roads per year

Long-term benefits require up-front investment

Patience Investment (NYU and Community)
CoGeneration/CHP Location
Plant underneath Warren Weaver Hall251 Mercer St.
Two options for new plant location– Mercer Street– Gould Plaza
Mercer Street OptionProsEmpty space/earth where plant can be locatedUltimate improvement to Mercer PlazaCommunity input on ultimate plaza designAll equipment fits below groundNo loss of classroom space for the UniversityMercer Street wider and would allow project work to take
place without full street closing
ConsDisruption to neighbors on Mercer StreetMore expensive construction project than Gould Plaza optionTemporary loss of trees in the immediate areaMercer street partially closed
Gould Plaza OptionProsLess disruption to Mercer neighborsEasier construction sitePotential for shorter construction time frame
ConsMore disruption to very compacted area on West 4th Street and
Washington Square Village West 4th Street a smaller street, full street would have to be
closed at timesPermanent loss of 15 classrooms (approx. 15,000 square feet)Immediate classroom relocation a difficulty, would most likely
need variances to allow the relocationClassrooms are used primarily by one school (Stern School of
Business); moving classrooms out of Stern’s building will cause complications for scheduling classes; and increases above ground foot traffic as students shuffle between classes
Not all equipment fits below ground; portions of equipment would have to be located above ground on 3rd Street
Expanding the conversation about Trees
If Mercer option pursued:
25 trees in current area• Manhattan Forestry/NYC Parks Department
overseeing and directing options for trees during project
• For trees that are removed and can not be replanted (for size, age and quarantine reasons): University pays to plant the equivalent # of new trees in Community Board #2 area
• University plants new (mature) trees at the end of the project
New Mercer St. Park
Mature trees, up to 30 feet tall can be planted
Plaza will be greener, nicer and more user-friendly
Heating vents will go away
Whole area benefits from beautification
