Improving Air Quality through Energy Efficiency

1
Improving Air Qualitythrough Energy Efficiency
Conservationin State Government
Taking Action

• John H. Rhodes
• Director, Energy Savings
• Department of the Treasury
• State of New Jersey

2
The Energy Problem

• Air pollution
• Global warming
• Limited resources
• Rising energy prices
• Shortfalls in supply
• Power grid constraints
• Reliance on imported oil
• Marketplace more complex

3
The Air Quality Connection

• Direct Obvious Impact
• Burning gasoline, diesel, oil
• Direct air emissions
• User can see smell it
• Indirect impact
• Electricity consumption
• User is disconnected from pollution source
• Power plant emissions are largely unseen
• Environmental impact not obvious to the user

4
Carbon Intensity
Significant source of pollution but largely
unseen by end-user
5
The Bottom Line

• Reducing energy consumption
• Reduces emission of greenhouse gases
• Reduces emission of air pollutants
• Reduces cost of purchased energy (avoided)
• Reduces waste of natural resources
• Reduces strain on supply infrastructure
• Puts downward pressure on energy prices

Its all good! (but its not all easy)
6
We get itNow what?

• We need to change our thinking, priorities,
  ACTIONS.TODAY!

7
New Jersey is Taking Action

• Governor Corzines Executive orders
• Increase energy efficiency in State government
• Reduce greenhouse gas emissions state-wide
• Established Office of Energy Savings (OES)
• located within Department of the Treasury
• Includes director and staff of three managers
• Driving energy conservation, cost reduction, and
  reduced emissions across all State agencies
• Raising visibility accountability for all
  agencies
• Set 5-Year goal
• Reduce energy consumption by 10

8
State Govt Energy Profile

• Consuming an est. 8.3 trillion BTUs annually
• 20,00030,000 electric gas bills/year
• 80,000 employees (energy consumers)
• 17 State departments
• gt 50 State agencies
• 300 facilities
• gt 4,000 buildings
• gt 12,000 vehicles

11
OES Initiatives Underway

• Evaluating State energy usage cost
• Forming department energy teams
• Taking immediate energy conservation actions
• EE project review ranking
• Developing an Energy Tracking System (ETS)
• Reviewing State vehicle fleet
• Exploring ways to reduce energy consumption for
  computers and office equipment (printers, faxes,
  copiers)
• Evaluating Redeveloping the State recycling
  program
• Investigating proposed legislation to allow
  long-term energy-savings contracts to deliver
  cleaner air now
• Building OES website to provide information,
  contacts

12
Immediate Conservation Actions

• Initial focus on Trenton facilities
• Buildings owned/occupied by State agencies
• Working with Div. of Property Mgt.
  Construction (DPMC) to reviewbuilding operations
  maintenance
• Adjusting control systems to reduce energy
  consumption for lighting, heating/cooling,
  motors, etc.
• Adjustments made to date are expected to deliver
• Reduced energy consumption of 3.5 million kWh
  annually
• Reduced air emissions of 1,900 tons CO2
• Equivalent to removing 278 cars or planting 374
  acres of trees
• 385,000 cost reduction benefit

13
Conservation Opportunities

• Raise awareness across all agencies
• Communications to reach all employees
• Make it personal
• Education about energy-environment link
• Point out office home opportunities
• Conservation, energy efficiency, renewable,
  savings
• Agencies share ownership to make it work
• Keep it fresh and interesting

14
EE Project Opportunities

• Lighting Retrofits
• Building controls
• HVAC
• Boiler upgrades
• Chillers
• High efficiency roof top units
• Fuel switching
• Phasing out use of fuel oil
• Combined Heat Power
• Renewable
• Cost-effective applications for PV, landfill gas,
  etc.

15
We Must Eliminate Energy Waste

• Leaving lights on when not needed
• Leaving computers running when not being used
• Redundant printing, copying, faxing equipment
• Leaving doors and windows open
• Setting heating/cooling temps too high/low
• Failing to use set-back temperature settings
• Failing to replace air filters when dirty
• Failing to maintain equipment
• Buying less efficient products equipment
• Buying vehicles that are too big, not energy
  efficient
• Failing to maximize waste recycling

16
Solar Power For State Facilities

• Fort Dix - NJ Dept. of Military Veterans
  Affairs
• 181 kW system, 180,000 kWh/year
• Online June 2005
• Homeland Security Bldg. Veterans Affairs
• 321 kW system, 340,000 kWh/year
• Due to be energized in April 2007
• State Police Emergency Operations Center
• 279 kW system, 297,000 kWh/year
• Due to be energized in April 2007

• Reductions To Date
• 136 tons CO2
• 0.4 tons SOx
• 0.3 tons NOx

17
Show me the clean air!(and money)

• Lighting Project Example State Office Building
• Replace T12 lamps with higher-efficiency T8
  technology
• 750,000 kWh reduction in annual electricity
  consumption
• 411 tons CO2 reduction
• 2.9 tons SO2 reduction
• 0.9 tons NOx reduction
• 90,000 annual energy cost reduction
• Better working environment for State employees
• Environmental Impact
• Equivalent to planting 80 acres of trees, or
• Equivalent to removing 59 cars from the road

18
Path Forward
