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.
All Of These Questions Are From This Document ! http://www.landofsky.org/wrp/index.html

Lighting Perspectives • Consumes 24% of Commercial & Industrial Electricity • 90% of Lamps Produced are Incandescent • Technology is Constantly Improving Principals for Maximizing Lighting Savings: • Illumination • Efficacy • 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
