AJL RESOURCES LLC CLEAN ENERGY SYMPOSIUM

ENERGY EFFICIENCY FOR END USERS With a Case Study
of Energy Progress at Rowan University
2
Energy Efficiency Actions

• This presentation
• Explains why energy efficiency is important
• Documents the actions of Rowan University in
  energy efficiency, renewable energy, and
  emissions reductions.
• Offers suggestions for the implementation of
  energy efficiency, renewable energy, and
  emissions reductions at your residence, farm or
  business.

Why Energy Efficiency ?

• High energy costs
• Changes in operation and other low cost measures
  have immediate value
• Other measures can have positive cash flow if
  financed good return on invested capital
• Combining energy efficiency measures and
  renewable energy measures (or RE purchases) can
  yield attractive paybacks
• Emissions reductions and a better environment -
  the right thing to do and positive PR
• Global and individual security
• America has one of the highest energy
  intensities in the world

Rowan Energy Plan, 1990s

• Rowan constructed a cogeneration plant in the
  early 1990s. The central plant houses a 1.5 MW
  Kawasaki Turbine that supplies three quarters of
  the electricity and heat for the campus.

5
Energy Improvements, 1990 - 2004

• Lighting retrofit with T-8 lighting
• 30 of the entire campus has been retrofitted (5
  buildings).

6
Energy Improvements, 1995 - 2004

• 45 variable speed drives on motors, fans and
  pumps installed from 1995 2002.
• 10 - 50 horsepower

7
Energy Improvements, 2004

• Rowan University Facilities began testing
  biodiesel fuel in their lawn tractors as a pilot
  program. (2004)
• Successful outcomes will result in the expansion
  in use of this fuel.

8
Energy Improvements, Ongoing

• Recycled 98 tons of paper in 2003, resulting in
• -1,960 trees saved
• -686,000 gallons of H2O saved
• -294 cubic yards landfill space avoided
• -5,980 lbs. of air pollution avoided
• -enough energy saved to supply 49 homes for a
  year.

9
Energy Actions, 2004

• In 2004, Rowan University became an ENERGY STAR
  Partner Institution
• Requires Benchmarking of Energy Use at Buildings
  and Implementation of Cost Effective Energy
  Efficiency Measures
• Applicable for Schools, Hospitals, Offices, and
  Other Buildings
• AJL Resources LLC is an Energy Star Partner
  (2001)
• Positive Public Image and Standing in Community

Future Efforts

• Rowan plans to expand and retrofit its old
  cogeneration plant.
• The new cogeneration plant is sized at 4.7 MW.
• It will avoid 1,375,000 in fuel and electric
  expenses per year.
• Reductions in CO2 emissions approx. 8,950
  tons/yr.

12
Future Efforts

• Retrofit 1 million sq. ft. of buildings with
  energy efficient lighting.
• Cost over 1 million.
• Project will save over 200,000 per year.
• Provides a 5 year payback.
• Avoid 1,238 tons of CO2 emissions per year.

13
Future Efforts

• A geothermal heat pump system is being
  investigated to replace the heating and cooling
  system in an existing 100,000 sq. ft. townhouse
  complex.
• Estimated to cost slightly more than a
  conventional system
• However, life cycle operating costs (capital
  costs, energy costs and maintenance costs) are
  lower.

14
Future Efforts

• Installing submeters.
• Read remotely.
• Provide automated reporting.
• 5 year payback.
• Avoid 537 tons per year of CO2 emissions.

15
Future Efforts

• Rowan plans to take a leadership role, along with
  the NJHEPS Energy Technical Team, in the
  development of a wind energy farm in south New
  Jersey to serve several higher educational
  institutions.

16
Future Efforts
The planned technologies allow Rowan to expand
its projected 235,000 sq. ft. and still
maintain a greenhouse gas emissions levels at or
below 1990 levels.

  mechanical and electrical systems, most users can
  cost effectively save between 10 30 on their
  energy costs
• There are direct rebates / tax incentives for
  residential and for commercial users in NJ
• There are sources available to help
• Energy efficiency is beneficial to you, your
  organization, the environment and global security
  we MUST become energy efficient
