12 Controls should be straightforward. An advanced degree in order to understand how should not be required. Lighting Control Design An overwhelming number of design options, components, work-arounds and should not be required. 12

13 Controls should have a simple cost breakdown. Fighting to understand the various component costs and what service is included in should not be required. 25 Controls should have a quick sales pitch. Hours to explain the basic system concept should not be required. 13

14 Controls should have inexpensive setup. Complicated pages of instructions and hours of should not be required. Controls should have simple wiring wire, 3-wire, 4-wire, Ethernet, twisted-shielded pair or DALI, WiFi, DMX, other complicated protocol interfaces to make one system should not be required. 14

15 Controls should not require software. Controls should have inexpensive programming. Complex coding languages and should not be required. 15

16 Controls should have quick commissioning. Years of training classes should not be required. Controls should have uncomplicated maintenance. Frantically searching for someone who is close by and qualified to make simple should not be required. 16

17 Controls should offer reliable energy savings. Calculations, spreadsheets, and guesses should not be required. Controls should be Future Proof. Endlessly searching to find the original designer to upgrade or make changes should not be required. 17

18 Controls should have a trouble-free warranty. A hard to find and hard to understand should not be required. Straightforward Intuitive to design Simple cost breakdown Quick sales pitch Inexpensive setup Simple wiring No software installation No programming Quick commissioning Uncomplicated maintenance Reliable energy monitoring Future proof Trouble-free warranty 18

34 What about Code Compliance of a well designed networked lighting control system? As of 2016, the DOE estimates that the use of lighting controls in commercial buildings will save $10.4 billion annually! 34

35 Comply with all Energy Codes. Several Energy Codes (like ASHRAE 90.1 and Title 24) now offer lighting power adjustment factors for using controls in spaces! (above and beyond their mandatory code requirements) 35

36 ASHRAE What is the Energy Saving Potential of a well designed networked lighting control system? 36
