Finding and Mining Today’s Energy Inefficiencies The Gold Rush of the 21 st Century

1. Finding and Mining Today’s Energy Inefficiencies The Gold Rush of the 21st Century Lorenz V. Schoff Energy Consultant “Finding Little Energy Inefficiencies, Generating Big Energy Savings”

2. Background Information 43+ years in Facilities Management AF Civil Engineering Officer Director of Facilities for Governmental Agency Original member of US DOE – Rebuild America Member of Committees working on Design Documents for ASHRAE and USGBC

3. Background Information – Commercial Bldg 18% of all energy use in the US – $100 Billion + Cooking 2%; Computers 3%; Electronics 6%; Ventilation 6%; Water Heating 6%; Refrigeration 6%; Lighting 30%; Space Heating 17%; Space Cooling 14% 4.9 Million Buildings 72 Billion SF Average site Energy Intensity – 91 kBtu’s/SF/Yr Average Primary Energy Intensity – 191 kBtu’s/SF/Yr

4. Observations Limited or Reduced Maintenance Improper Light Levels Energy Inefficient Equipment To Many Personal Appliances Improper Use of Controls

5. Observations Limited or Reduced Maintenance Dirty Filters increase energy use (EU) Cleaning of light lenses reduce light levels Increased friction increase EU Leaks around doors and windows increase EU

6. Observations Improper Light Levels Office areas over illuminated Hallways over illuminated Storage and Mechanical Areas Use of shades and blinds

7. Observations Energy Inefficient Equipment HVAC Equipment Motors Appliances

8. Observations To Many Personal Appliances Personal Heaters Refrigerators Microwave Ovens Fans

9. Observations Improper Use of Controls Light Switches Thermostats Energy Management Systems

10. How Buildings are Operated? Without knowledge of energy use and impact of individuals actions Lack of Utility Management No Energy Policy/Regulation No approved Energy Management Plan

11. What is Energy Management? A process to obtain an Understanding of: Building Utilization How energy is being consumed Energy Systems Installed A process to: Improve overall energy efficiency and reduce impact on the environment

12. What is Energy Management? Understanding of Building Utilization What areas are used and when? Patterns of occupancy and habits Space compatible with programs and energy efficiency How’s the Energy is being consumed? What are the light levels? Identifying Plug and Phantom Loads HVAC equipment operations – EMCS Electrical Systems

13. Gather the Energy Utility Data Use this data to establish a baseline – kBtu’s/SF/YR Establish Baseline Portfolio Manager will assist in validation of Efforts Who reviews this information/data? Conduct an Energy Use Audit of Each Facility Determine Building Occupancy Profiles Determine Building Characteristics and Systems Conduct an Plug Load Survey Data, Info, Baseline

14. Plug and Phantom Loads What is a plug load? How best to control plug loads? What is a Phantom load? Means of controlling Phantom Loads?

15. It’s the Little Things Turning off Lights Offices Storage All Areas Control of Plug Loads and Phantom Loads Cleaning Operations Use of Facilities Best Practices in Operations, Maintenance and Behavior

16. Energy Awareness Training All Personnel KISS Newsletters Make it part of daily routine They can be part of the solution or part of the problem Best Practices in Operations, Maintenance and Behavior

17. Potential Energy Savings • Use of Lighting Systems – 15% • Lighting Controls – 10% • Energy Awareness Training 10-15%

18. It’s Not Rocket Science Nothing is Impossible it just takes time and resolve
