Improving Air Qualitythrough
Energy Efficiency & Conservationin State Government
John H. RhodesDirector, Energy Savings
Department of the TreasuryState of New Jersey
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
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

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
It’s all good!(but it’s not all easy)
We get it…Now what?
• We need to change our thinking, priorities, ACTIONS….TODAY!
New Jersey is Taking Action
• Governor Corzine’s 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%
State Gov’t Energy Profile
• Consuming an est. 8.3 trillion BTUs annually• ~ 20,000–30,000 electric & gas bills/year• ~ 80,000 employees (energy consumers)• 17 State departments• > 50 State agencies• ~ 300 facilities• > 4,000 buildings• > 12,000 vehicles

MEASURABLE RESULTS
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
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
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
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.
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
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
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
Path Forward
• Get State measurement system in place• Evaluate energy performance, benchmark• Establish department goals• Identify & pursue cost-effective projects• Promote energy conservation• Raise visibility & accountability for all• Communicate with all State employees• Foster team environment - interagency• Track & report results• Recognize top performance• Drive continuous improvement
