• Step 4 Develop an Energy Savings Plan
• First Steps
• Identify Opportunities
• Develop Solutions
• Quantify Potential Savings
• Identify incentive opportunities
• Prioritize
• Develop Justifications

13

• a) First Steps
• Seek Assistance
• Go to school
• Attend workshops
• Conduct surveys

14
b) Identify Opportunities c) Develop Solutions

• Start with Low-Cost and No-Cost
• Better Habits
• Proper Maintenance
• Better Operation
• Better Controls
• Better Systems

15
No-Cost Actions

• Better Habits
• Turn off lights and office equipment
• Take advantage of natural daylight
• Keep windows and doors closed
• Program programmable thermostats

16
Low-Cost Actions

• In the Kitchen
• A lid will increase cooking efficiency by 14
• Dont boil long evaporation causes heat loss
• Every second an oven door is open looses 3-10º F

17
Low-Cost No-Cost Actions

• Proper Maintenance
• HVAC inspection
• Boiler inspection and tune up
• Fix steam trap leaks
• Replace Filters

18
Low-Cost No-Cost Actions

• Better Operation
• Hot Water Heaters
• Install timers
• Minimize use
• Adjust temperature
• Make seasonal adjustments

• Benefit
• Each 10 degree Fahrenheit reduction in water
  temperature will generally save three percent to
  five percent on water heating costs

19
No-Cost Low-Cost Actions

• Better Operation
• Run dishwashers at capacity
• Fill coolers to optimal capacity
• Keep hot items away from ones you want cold

20
Low-Cost Actions

• Better Controls
• Install timers
• Tune Energy Management System (EMS)
• Benefit
• Reduce costs through efficient equipment usage

21
Energy Star Appliances

• Better Systems
• Cooking equipment
• accounts for 32 of
• average food service
• energy consumption

• Joint US DOE and US EPA Program that certifies
  appliances

22
Low-Cost No-Cost Actions

• Better Systems
• Lighting
• Compact Fluorescents
• (CFLs)
• T-8 and T-5 Florescence
• Automated or Programmable Controls

23

• Make a list of projects
• Best Practices
• Improved Maintenance
• System Modifications
• Capital Investments

24

• d) Quantify Benefits
• Cost Savings
• Energy saved (kWh or therms)
• Demand reduction (kW) (if applicable)
• Reduced maintenance
• Other Benefits
• Increased system capacity
• Better comfort

25
Financial Assistance

• Identify Potential Incentives
• Federal Tax Incentives
• State Tax Incentives
• Utility Demand Side Management Programs

26

• f) Prioritize Projects
• Ease of implementation
• Cost of project
• Benefit of project
• Timing of incentives
• Risk
• Persistence of benefit

27

• Developing Project Justification
• Cost Benefit Analysis Example
• Reduce lighting by 100,000 watts
• Pay 0.08/kiloWatt hour
• Lights on 3,500 hours / year
• Savings 280
• Project costs 350
• Simple Payback 15 months

28

• Step 5 Implementing Projects
• Identify funding
• Research availability of incentive programs
• Determine who can do the work
• Volunteers
• Contractors

29
Step 6 Measurement Verification

• Compare against baseline
• upon completion
• And 6 and 12 and 24 months after
• Complete the cycle Tell Management!
