2 AGENDA Considering Retrofit Process Offices Warehouse / Manufacturing Outdoor Controls Why Led Conclusion 1

3 CONSIDERATIONS: RELAMP, RETROFIT, NEW LUMINAIRE New Construction Renovation - Condition Of Existing Equipment? - Existing Technology? Owned Or Leased Space? What Are The Design Goals? - Maintain Or Improve Light Levels - Reduce Light Levels - Incorporate Lighting Controls - Aesthetic Requirements What Is The Desired Payback Not All Products Are Created Equally 2

4 SITE AUDIT Audit Of Existing Lighting To Determine Quantities Technology Hours Of Operation Voltage Existing Light Levels Fixture Spacing Lamping Other Relevant Information. This initial stage Is Where The Condition Of Existing Equipment Is Determined And The Design Goals would Be Discussed. 3

5 ENERGY ANALYSIS Energy Analysis Created To Determine Existing Power Consumption vs Proposed energy savings Recommendations Made Based On Design Goals And Required Payback Appropriate Products Selected To Achieve Design Goals Cost of project determined Incentive amount calculated based on retrofit approach ROI determined based on recommended approach Good Information In Good Information Out! 4

6 RECOMMENDATIONS Based On Current IES Recommended Practice, Recommendations Will Be Made That Will: Ensure Adequate Light Levels Achieved Quality Of Light Improved Aesthetics Improved (If One Of Design Goals) Energy Reduction Achieved Maintenance Reduced Maximize Available Incentives Achieve Shortest ROI While Meeting All Other Requirements 5

7 OFFICE SPACES Typical Office Spaces Can Consist Of The Following: Pot Lighting Recessed Fixtures ( 2x4, 2x2 Or 1x4) 6 Surface Wraps

8 OFFICE SPACES Retrofit Options Depending On The Information Gathered During The Audit, There Are Several Retrofit Options Available For Offices. Pot Lighting Can Either Be Re-lamped With Led Or Retrofitted With Kits. Which Option Is Chosen Can Be Decided By Aesthetics Or Budget! If The Pots Are Old And The Flanges Faded, new Retrofit Kits May Be Desirable. Either Choice Will Save Energy And Reduces Lamp Changes For Many Years And Both Are Incented. Recessed Fluorescent Fixtures Can Either Be Retrofit With New Energy Efficient Ballasts And Led Lamps Or Replaced With Dedicated Led Fixtures. De-lamping Is Also An Option. If Improved Aesthetics Are Desired An Led Architectural Fixture Can Be Installed. 7

9 OFFICE SPACES (DEDICATED LED FIXTURES) EXISTING : 30-2X4 4 LAMP T8 120V RECESSED New Led Fixtures (Most Desirable) Energy Savings = $ Cost Installed = $ 4, Utility Rebate = $ 1, ($50 Per Fixture) ROI With Rebate = 35.2 Months Dedicated Fixtures Are More Likely To Provide Accurate Energy Savings As Well As Efficiency And Performance. Dedicated Drivers And Integrated Thermal Management Ensure A Long Term Maintenance Free Installation. 8

10 OFFICE SPACES (T12 TO HYBRID: RETROFIT & NEW) EXISTING : 30-2X4-4 LAMP T12 120V RECESSED Retrofit: 4 Lamp T8 ISN Ballast / Led T8 Lamps Energy Savings $ 1, Year Cost Installed: 3, Utility Rebate = $ ROI With Rebate = 24 Months New Led Fixtures Energy Savings = $1, Cost Installed = $ Utility Rebate = $ 1, ROI With Rebate = 26.7 Months Note: The New Incentives Are Targeting T8 so Any T12 Retrofit Must Be Calculated Under The Custom Track. 9

11 OFFICE SPACES (T8 TO LED LAMPS ONLY & BALLASTS) EXISTING : 30-2X4 4 LAMP T8 120V RECESSED Retrofit: If Ballasts Are 5 Years Or Less, Re-lamping With Led Lamps Is An Option Energy Savings = $ Year Cost Installed = $ 2, Utility Rebate = $ ( $ 7 Per Lamp ) ROI With Rebate = 30.5 Months CAUTION: DEPENDING ON BALLAST COMPATABILITY AND AGE, THE ENERGY SAVINGS MAY NOT BE ACCURATE. De-lamp: New High Efficiency Ballasts With Led Lamps (More Desirable) Energy Savings = $ 1, Cost Installed = $ 2, Utility Rebate = $ ROI With Rebate = 19.5 Months INSTALLING NEW BALLASTS AND LAMPS ENSURES MORE ACCURATE ENERGY SAVINGS. 10

12 OFFICE SPACES (DEDICATED LED FIXTURES) EXISTING : 30-2X4 4 LAMP T8 120V RECESSED New Led Fixtures (Most Desirable) Energy Savings = $ Cost Installed = $ 4, Utility Rebate = $ 1, ($50 Per Fixture) ROI With Rebate = 35.2 Months Dedicated Fixtures Are More Likely To Provide Accurate Energy Savings As Well As Efficiency And Performance. Dedicated Drivers And Integrated Thermal Management Ensure A Long Term Maintenance Free Installation. 11

13 WAREHOUSING & MANUFACTURING Typical Outdated Lighting In These Spaces Would Be HID (Highbays) And 8 T12 Industrials The Approach To These Spaces Is Usually Straightforward As Many Buildings Were Designed With HID Highbays And One For One Replacement With LED Highbays Will Provide The Required Light Levels While Saving Energy And Maintenance Over The Long Term. Factors To Consider When Relighting This Type Of Space 1. Fixture Spacing 2. Mounting Height 3. Reflectance 4. Type Of Warehouse (Food Falls Under CFIA Standards For Lighting) 5. Is A Redesign Practical To Reduce Fixtures 6. Are There Special Lighting Requirements 7. Occupancy Sensors 12

16 BEFORE AND AFTER 15

17 OUTDOOR Replacement Of Outdoor Lighting With LED Has Advantages That Indoor Does Not! Heat: Since Outdoor Fixtures Are Not Used During Mid-Day They Tend To Run Cool All Of The Time Thus Extending Life. Cold: LED Operates Best When Cool Therefore Winter Conditions Are Advantageous To An LED Installation. Maintenance: Due To The Extended Life Of Properly Designed Outdoor LED Fixtures, Maintenance Is Drastically Reduced And When Calculating ROIs One Of The Most Important Factors Right Behind Energy Savings. Since We Are Replacing HID Systems With Lamps Life Of 18,000 Hours And The Equipment Necessary To Provide Service Is Expensive, Maintenance Savings Long Term Can Reduce The ROI Even Though The Initial cost will be more. 16

20 CONTROLS IN RETROFITTING Implementing Controls Wherever Possible Can Have A Very Beneficial Affect On Both Energy Savings And Maintenance Of The Lighting System. Switch Sensors In Offices, Boardrooms And Washrooms Can Remove The Human Element To Ensure Lights Are Off When No One Is In The Space. Photo sensors In An Office Can Dim Led Fixtures To Pre-set Levels. In Warehousing And Plants, Fixture Mounted Sensors Can Ensure Energy Savings In Spaces Not Often Occupied. Parking Garages: Either Fixture Mount Or Zoning Areas Can Reduce Energy. When The Lights Are Off They Are Increasing In Lifespan! Outdoor: Area Lighting With Led Can Now Be Set Up To Dim To Half When Unoccupied And Come Up To Full Output When The Area Is Entered. Photo Controls On Each Fixture Can Insure They Shut Off In Daylight Hours. With LED Retrofitting Dimming Drivers Are Becoming Standard Making Control Much Easier Than With Past Technologies. 19

21 WHY LED FOR RETROFIT / REDESIGN Energy Efficient (25% - 80% Energy Savings) Longer Useful Life Rugged No Warm Up Cold Friendly Directional Color Rendering Environmentally Friendly Controllable Dimming - Color Lower Cost Of Ownership Increased Quality Of Light (Improved Productivity, Performance And Health) 20

22 WHAT TO KNOW ABOUT LED As We Move Forward At Warp Speed Into The World Of Led Lighting We Must Consider Some Very Important Aspects Of This Revolution In Order To Ensure We Can Make Educated Decisions When Spending Money To Convert! There Are More And More Products Coming Into Canada From Companies We Know Nothing About, Therefore We Do Not Know Their Quality Control Procedures, Their Testing Much Less Their Components. It Is One Thing To Power Up A Product And Admire How Bright It Looks But How Confident Are We About Its Stated specifications? Discussion Of Late Within The Professional Lighting Community Has Been About Products Actually Standing Up To Their Stated Specifications Such As L70, Lm80 & Tm21, Lumen Output Etc. Not All Products Are Created Equal! 21

23 CONCLUSION I Urge You To Learn More About What Makes LEDs So Compelling And Be A Well Informed Customer. When Considering A Lighting Retrofit And / Or Redesign Find A Qualified Lighting Professional With Access To A Variety Of Products! Niche Vendors Often Limit Your Options Which Often Times Can Lead To Trying To Fit The Wrong Product In Because Of Lack Of Breadth In The Product Line. Ask A Lot Of Questions And Make Sure You Are Dealing With A Reliable Vendor And A Quality Product. The Time Is Now To Seriously Consider LEDs For Your Retrofit Project. 22
