ESF Energy Inputs * * reflects energy use factors

1. Energy Conservation Measures - energy saving renovations, technologies, & facilities upgrades. 2. Alternative Energy Projects - onsite clean & renewable energy projects to power existing structures. 3. Green-Building Energy Systems - design of new construction with integrated renewable energy systems. Ultra efficient building envelopes allow surplus energy to flow to other buildings. 4. Campus Action Campaigns - efforts by ESF community for increased awareness, voluntary behavioral adjustments, policy changes, reduced waste, etc. 5. Forest Carbon Sequestration - designation & management of select ESF forest properties for carbon sequestration & storage purposes. Five-Fold Path Energy & Emissions Reduction Total: 40 Initiatives

 $1.2M chiller replacement saves ESF $170,000/yr and reduce annual oil consumption by 2,500 barrels/yr  Thermostat settings, reduced in winter & increased in summer. (very cold over winter break)  Turn off the lights and computers!  NYPA financed energy audits and efficiency improvements. Conservation = efficiency /

~80% Conversion efficiency 17% of campus electrical requirements Funded by Grants: NYSERDA US DOE EPRI ~$1.5M Fuel Cell, Efficient Power and Heat Generation

 40 KW of installed ($400,000)  $200,000 funded by NYSERDA

New “zero net energy” showcase building for campus. Design includes biomass combined heat and power, PV, green roof, passive solar and rain gardens. Gateway building – LEED Platinum

Gateway Building Energy Efficiency

 8,000 MBtu CHP Wood Pellet Steam Boiler  8,000 MBtu CHP Natural Gas Boiler  200 kW Back-pressure steam turbine  30 kW CHP Biodiesel Micro-turbine  Dual 65 kW CHP Natural Gas Micro-turbines  kW Solar PV array Gateway Energy System

 CHP System is a 25% improvement to overall energy efficiency ◦ Provides 75% of campus thermal needs and 20% of campus electrical needs.  Offset 54,000 MMBTU Fossil Fuels Annually ◦ 18,000 MMBTU from efficiency improvements ◦ 36,000 MMBTU from fuel switching improvement  System is projected to save ESF $450,000 annually, and provides a $1.5 million NPV over 15 years Combined Heat and Power System
