6 Why Focus on Lighting? Source: U.S. DOE 6

7 Problem: Wasted Lighting Energy Buildings: Are over-illuminated Don t take into account daylight Leave lights on in vacant spaces or after operating hours 75% were built before % of today s buildings are expected to be in use in 2030 What s wrong with this picture? Most buildings don t deliver the right amount of light where and when it is needed. Lighting is often set at a worst case level, which is usually higher than desired. -- Stephen Selkowicz, Lawrence Berkeley National Labs 7 7 7

8 New York s 22,000 largest buildings, concentrated largely in Manhattan, account for roughly 45% of total energy consumption 8

9 NYC Lighting Laws Local law 973-A, Article 310 ( lighting upgrade law ) Energy Conservation Construction Code of New York State (ECCCNYS 2010) Local law 48 9

10 Article 310 Applies to: Building in NYC over 50,000 sq. ft. 2 or more buildings on the same tax lot that together exceed 100,000 sq. ft. Requirements: Interior and exterior lighting must meet current building energy code by Jan 1,

11 Article 310 Exceptions: Lighting system elements and lighting power densities (Watts/sq. ft.) that comply with ECCCNYS 2007 Dwelling units Houses of worship 11

16 Relighting Upgrading the lighting without breaking the ceiling plane: Replace lamps, ballasts, and optical system using the existing fixture housing Benefits: Minimize waste Use of workspace while renovating Fast, simple payback Ongoing savings from reduced energy usage and maintenance costs Easy to install 16

17 Relighting An Example Relighting with lighting kits: Ideal solution for renovating obsolete lensed or parabolic troffer systems Convert 4- or 3- lamp fixtures to 2- lamp T5 or T8 fixtures Proper lighting eliminates the cave effect by delivering the ideal amount of light to walls, work surfaces, and people Energy consumption is lowered by up to 60% compared to fixtures with four T12 lamps Fewer, longer-life lamps result in reduced maintenance and disposal costs 17

18 Interior spaces: Offices, Retail, Training Rooms Troffers Downlights New Luminaires Big Box Retail, Warehouses, & Distribution Centers Exterior areas: Walkways, Entrances, Exits, Security, & Surrounding Areas Parking Garages & other Rough Service Applications 18

19 Fluorescent & LED Troffers Look for: Number of lumens delivered per watt High lumen maintenance factor Luminaire adjusting itself to eliminate the waste of over-illumination Potential dimming capabilities Integrated controls Offices, Retail, Training Rooms 19

20 Downlighting LED, CFL, HID & Incandescent Considerations: Cutoff Finish Ease of installation Photometric pattern Color Spacing criteria Compatibility with controls Offices, Retail, Training Rooms 20

21 Big Box Retail, Warehouses, & Distribution Centers High Bay Fluorescent & LED High bay fluorescent: Cooling vents aid in thermal management Allows for quick installation of occupancy sensor Significant energy savings Intelligent LED: Saves energy. 50% more efficient than HID solutions. Reduces maintenance costs. Predicted useful life of more than 100,000 hours. Supports multiple applications. Capable of effectively lighting open areas and aisles. 21

22 Walkways, Entrances, Exits, Security, & Surrounding Areas LED exterior luminaires, look for: The LED driver and electronics being thermally isolated from the heat-generating light engine to ensure long life. The optical system should control light above 90 degrees, eliminating wasteful up light. Other issues include: Color (CCT & CRI) Thermal management Controllability Power factor THD Exterior Lighting 22

23 Exterior Lighting Parking Garages & other Rough Service Applications LED & Fluorescent: Good for new construction and renovations Better illumination Available with LED or T5, T5HO and T8 fluorescent lamps Enhanced light quality and distribution over HID Provides uplight while reflectors offer better uniformity and improved vertical illumination Energy-efficient Reduce energy by as much as 30-50% Payback of less than two years. 23

33 What is a ballast? With an incandescent lamp: - The electrical characteristics of the filament wire limit and manage the flow of the electrical current. With a fluorescent or HID lamp: - The electrical current flows through gas and the gas is unable to manage the flow of the electrical current. The ballast provides the proper conditions for starting, then maintaining the lamps operation once it is started. 33

34 Metal Halide Pulse Start: Required in new luminaires W since January 1, 2009 (EISA 2007) Benefits: Improved lumen maintenance over lamp life Lower wattage systems deliver similar maintained light levels Better color consistency lamp to lamp and over life High CRI ceramic lamp technology Electronic systems deliver: Metal Halide Ballast Technologies Universal input voltage V High power factor, low THD and constant power regulation Energy savings up to 15% compared to magnetic systems Improved lumen maintenance and extended lamp life Consistent color temperature and CRI over lamp life 34

44 Lighting Management Strategies Scheduling: Lights automatically turn off or are dimmed at certain times of the day or based on sunrise or sunset. Occupancy/Vacancy Sensing: Automatically turning lights off when people vacate the space. Multi-level Lighting/Dimming: Proving users one or more light levels other than full-on and full-off. Daylight Harvesting: Automatically adjust light levels based on the amount of daylight in the space. 44

45 Lighting Management Strategies High end trim/tuning: Set target light level based on occupant requirements in the space. Personal Light Control: Allow users in the space to select the correct light levels for the desired task. Controllable Window Shades: Allows users to control daylight for reduced solar heat gain and glare. Demand Response: Reducing lighting load at times of peak electricity pricing. Plug-load Control: Automatically turning task lighting and other plug loads off when they are not needed. 45

46 It s all about the money Labor savings of up to 75% over hardwired Installs in ¼ the time of hardwired Eliminates need for dedicated control wiring, switch legs, traveler wires and other materials 50% installed cost savings over hardwired Ideal retrofit solution No damage to walls or ceilings Little to no disruption to operations The Value of Wireless 46

47 Emerging Technologies: Digital What is digital lighting control? De-centralized control system that incorporates occupancy sensing, daylight harvesting, scheduling, switching and/or dimming of lightings, software based programming and personal lighting control options Every device in every zone or network is digitally addressable Systems have the intelligence to make their own control decisions All devices are connected with low voltage wiring Devices can be wired using daisy chain instead of home run design 47
