2 Requirements For Performing A Professional Lighting Audit By Stephen Guthrie President EnerNet, Inc.

3 Rules of the Game If you want to play this game ….”You Must Follow The Rules” –Rule #1 - Come Prepared – The Right Tools Are Key –Rule #2 - Take the Time To Learn About The Environment You Are Working In –Rule #3 - Don’t Be Rushed –Rule #4 - Pay Attention to All The Details –Rule #5 - Follow Rules 1, 2, 3 & 4 –Rule #6 - Its Not Really A Game

4 Five Major Elements There are Five Key Elements To A Successful Lighting Audit –Site & Building Information –Room & Usage Information –Luminaire Information –Controls / Switching Information –Problem Areas / Miscellaneous

5 Lighting Audits Require Great Attention to Detail The First Step is the Interview Process –Determine the Scope of The Survey –Determine if there are any measures that have been performed in the past….What Type of Measures, When? –Identify other “Key Elements” to avoid costly mistakes, liability and embarrassment

6 Site & Building Information The Interview What Types of Questions Should I Ask? –What is the Square Footage of Building(s)? –Is there an energy management system? –Does the EMS control the lighting? –Are there other control measures? –Is Voltage uniform throughout the building? –Is there an emergency generator / inverter system? –Are there battery back-up units in fixtures?

7 The Interview (con’t.) What Other Questions Should be Asked? –Do the fixtures have modular connectors / wiring? –Is the building wired for power-line carrier? –Are there sensitive environments where special equipment is used such as scanners? –Are there other control measures? –Is there asbestos in the ceiling / PCB’s? –Has there been any injuries or complaints related to lighting?

8 The Interview (con’t.) It’s Important to get the Basic Essential Information –Site Contacts –Phone, Fax & –Electric Utility Host / Rate Structure –Operating Hours / Characteristics

9 Step 2 - Room Specific Information Establish the General Room Parameters –Operating hours / zones within a building –Site Maps or CAD Drawing Reference –Suite Numbers / Room #’s, Names or ID’s –Sloped Ceilings / Structural Issues (ducts) –Ceiling Types –Measurements If Required (x,y,z) –Illumination Levels, Daylight Contributions, Etc.

10 Step 3 - Luminaire Specific Information Determine the Vital Characteristics –Luminaire Types & Quantities –Configuration, Tandem Wiring, Connectors –Dimensions & Properties (explosion, vandal resistant, wet/damp location) –Battery Back-Up, Dedicated Emergency Circuits, etc.

11 Step 3 - Luminaire Specific Information Determine the Vital Characteristics (con’t.) –Lamp Types & Quantities Per Fixture –Configuration / Jacket Type (Par, R, Bi-Pin) –Dimensions & Properties (color temperature, wattage, voltage rated) –Lens Types

12 Step 4 - Controls / Switching Specific Information Determine Control Methods & Strategies –Is there a central Energy Management System controlling the Lighting? –Are there room controls such as Occupancy Sensors or Time Clocks? –What are the Switching Types & Styles? –What Recommended Controls / Types should be used?

13 Step 5 - Problem Areas / The Exit Interview Determine if there are Any Other Lighting Issues or Problems –Maintenance Issues –Adequate Illumination In Critical Areas –Complaints of Eye Fatigue or Headaches –Lamp Flicker, Switching Problems, Etc.

14 Summary Make A Set of Rules & Follow Them –Don’t Take Shortcuts – Shortcuts Add Cost –Spending The Time In The Field Gathering All the Right Data is the “MVC”, a Most Valuable Consideration To The Project Developer –Come Prepared Calibrated Light Meters Graphing Paper Digital Cameras Measuring Instruments

15 Summary Make Use of Your Best Tools Common Sense A Clearly Defined Plan Careful Execution

16 THANK YOU! EnerDog Says Woof!
