ENERGY STAR (ES)ENERGY STAR (ES)

– “ENERGY STAR is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy helping us all save money and protect the environment through energy efficient 

d d ”products and practices.”– “The national energy performance rating is a type of external benchmark that helps energy managers p gy gassess how efficiently their buildings use energy, relative to similar buildings nationwide. The rating system’s 1–100 scale allows everyone to quickly understand how a building is performing — a rating of 50 indicates average energy performance, while a rating of 75 or better indicates top performance.”

The ProgramThe Program

• Save energy when nobody cares ‐ during unoccupied hours– 180 school days in 365 day year=50%– 12 hours school use in 24 hour day=50%– 50% of 50% =25% occupied hours vs. 75% unoccupiedp p

• Use it when needed and turn it off as soon as not needed.– Night and weekend setbacks.– Energy Curtailments.Energy Curtailments.

• Ensure all equipment is operating as designed.• Establish new operation schedules and procedures.

O t d i t i th HVAC t t t th• Operate and maintain the HVAC systems to meet the temperature policy (68° to 72° occupied temperatures during the heating season).

Potential SavingsPotential Savings

• The potential first year’s savings as the resultThe potential first year s savings as the result of the energy management program is estimated at $500,000 to $600,000.

• Subsequent years will yield additional savings with the potential total savings in excess of $1,500,000 per year.

• This will be achieved without capital expenditures through operational and cultural changes.

Implementation ChallengesImplementation Challenges

• Equipment and automatic temperatureEquipment and automatic temperature control deficiencies.

• Training on the operation of the building and• Training on the operation of the building and control systems.

All ff i i d i• All staff motivation and cooperation to conserve energy.
