Managing Energy Consumption ENERGY SAVING IS GOOD IF IT SAVES YOU MONEY. ENERGY SAVING IS BETTER IF IT MAKES YOU MONEY.

In what ways do you use electric power?  Illumination.  Heating, Cooling and Ventilating.  Motors.  Office Equipment.

How do you begin to conserve electric power?  Evaluate where you use the most energy.  Administration and Communication.  Utility Accounting.  Office Equipment.  New Construction.  Vehicle Use.  Lighting.  Space Conditioning – HVAC.  Building Envelope.  Miscellaneous Equipment.

Lighting Perspectives  Consumes 24% of Commercial & Industrial Electricity  90% of Lamps Produced are Incandescent  Technology is Constantly Improving Principals for Maximizing Lighting Savings: 1. Illumination 2. Efficacy 3. Control

Light Source Efficacy Light Source Maintained Lumens Per Watt

Lighting Tips  Inefficient bulbs create serious heat that can run up air conditioning costs.  CLEANING fixtures once a year can save as much as 30% in room lighting.  Is outdoor lighting being used well and inspected regularly?  Old style EXIT Signs can cost $250 /year to run, while LED EXIT signs can cost $3/year.

The Easy Lighting Cost Savers  CHOOSE LOWER LAMP WATTAGE. Today’s bulbs are brighter but use less wattage.  TURN OFF UN-NEEDED LIGHTS.  USE TASK LIGHTING. It puts light where it is needed, saving wasted overhead lighting.  INSTALL TIMERS AND MOTION SENSORS. Controls can SAVE 10% or more of lighting costs.

HVAC Systems  Removes or Adds Heat  Removes or Adds Humidity  Provides Ventilation  Cleans the Air HVAC Checklist  Proper Equipment Application  Efficiency Improving Hardware  Operational Adjustments  Maintenance Practices

Heating, Ventilation, and Air Conditioning (HVAC)  HVAC systems have coils that need cleaning and/or filters that need changing. Dirty coils and filters cut efficiency and could create extra costs.  HVAC Fan motors and drive belts need maintenance. A worn belt can mean 10% extra motor operating costs.  Look for heat sources under thermostats. Such as coffee pots or computers.  Use Zone and Automatic Controls.

Employee Power Saves Energy  Employee Common Sense makes all the difference in energy savings.  What employees and management know about energy saving helps then to spot energy waste.  Rewards and incentives remind employees to save energy.  Energy saving practices often save work-hours.

Energy Bills can LIE  Problems with meters could go undetected for years.  Compare electric bills with the same periods in previous years to detect costly hidden problems or practices.  Rate Schedules can be adjusted once a year to get the best rates, as equipment, practices, and circumstances change.  Rate Schedule fees and penalties can show something is wrong with your operation.

Energy Audit Process  Review Billing History  Two Year History - all sources  Demand data when available  Analyze building systems  Operational Hours  Type of Equipment (i.e. chilled water cooling vs. rooftop AC)  Age of Equipment  Calculate load for major building systems  Review what systems are easiest to modify
