Driving Efficiency Up and Costs Down

 

Project Highlights:

  • 84% reduction in lighting electrical energy usage
  • +50% from lighting controls—reduced run hours, dimming
  • ROI payback 3.1 years
  • Improved light quality, safety
  • Easy to set up and install

This graph illustrates energy reductions realized by the combined lighting upgrade+controls implementation.

Much of the energy savings not only comes from the reduction in watts from LEDs but a good portion comes from aggressive scheduling. Originally lights were on 100% at night year-round. Controls enable 55% savings in energy based on reduced hours of operation. The Lumewave Ethernet Gateway is mounted on the roof of the dealership, enabling it to wirelessly communicate to each TOP900TL light controller. One of the advantages of using
wireless controls is no additional wiring is needed, making the system easy to set up and install, saving additional costs.

Best Practices:
Flexibility, Security

Lumestar software makes the lighting controls solution fully programmable so it can be customized for each application. Each light fixture can be controlled individually or a number of fixtures can be programmed into a group. Each group can have different parameters based on application needs.

For example,

  • The frontline fixtures are programmed
    to come on at 100% at a half hour before
    sunset, and at 10pm the front row is
    programmed to dim to 25%.
  • For security and customer service each
    pole has a motion sensor. If a person or
    automobile is detected, the lights come
    on at 100%. If the motion sensor detects
    no activity in the area after 10 minutes
    the fixtures shut off.
  • At an hour before sunrise all of the luminaires
    are back on at 100% power for
    security and convenience for the incoming
    staff.

LED lighting and intelligent controls save dealership big money and makes lighting worry free for ten years.
Michigan is a progressive small town dealership with exceptional facilities. So when Dave Knapp, President of Knapp Motors, decided to upgrade his lighting, he chose GUSCO Energy of Toledo, Ohio to design a lighting solution that would highlight their line of Fords and Lincolns as well as the facility itself.

Opportunity
Dave Knapp Ford is located on a busy highway on the Southwest side of Adrian, Michigan in a great location at a corner,
providing exceptional visibility to traffic heading out of town. Like most typical automotive dealerships, Knapp Ford was using 1,000 watt metal halides on the front row and quad head 400 watt metal halides in the center lots with a the standard mechanical timer. It made sense to design a lighting system that not only saved energy but effectively showcased the vehicles to make the best use of the prime location.

Solution
GUSCO Energy has designed and installed many LED solutions for automotive dealerships. So they used their experience and knowledge and designed a solution using Cree® LED Edge HO luminaires with Autofront technology and true white 90 CRI for the front row and Cree Edge® LED HO for the center lot. To further enhance the functionality of the solution, GUSCO Energy used a Lumewave by Echelon wireless lighting control system. GUSCO installed a central Lumewave Ethernet Gateway, Lumestar software, and TOP900TL twist lock wireless lighting controllers on each light fixture. Lumewave EW-205 motion sensors complete the solution.

Energy Reduction: 84%
Knapp Ford was using 56,704 watts to light the exterior of the facility and based on their hours of operation the site lighting consumed 186,272 kWh annually at a cost of $31,604. The designed solution from GUSCO Energy uses a maximum 9,152 watts and based on the hours of operation lighting consumes 30,064 kWh annually with a cost of $5,100— for a savings of $26,503 or an 84% reduction in energy used.

Grouping
graphThis graph illustrates the luminaire placement by optics type. A good way to determine groups for your Lumewave controls is to look at your Visual file and group fixtures by areas and need. For example GUSCO and Lumewave engineers grouped all of the “E’s” in one group because they were in the front row and each fixture in this group had the same purpose and optical output.

Luminaires A, C and D on the left side were put into a group and luminaires A and B on the right side were put into one group. In conclusion, planning for lighting controls unlocks the true value of your new LED fixtures.
