•
•
Implement a variety of technologies on campus, to
Engage our students, faculty and community, and

2) Quantitative Road Map to...
•
•
•
•
Carbon Neutrality
Reduced Energy Use
Reduced Fossil Fuel Dependence
A greener & more sustainable campus
3) Improve ESF’s financial position
* reflects GWP & Emission Factors
1.
Energy Conservation Measures - energy saving renovations, technologies, &
pg
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.

40 Initiatives
Combined Heat and Power System
Cornerstone of our plan
Part of a new building that will become the
“gateway”
g
y to the campus
p
The building will be an energy efficient design, LEED Platinum+
We estimate the building will use 30-35,000 BTU/sq ft/year
