Expected results compared to the previous lighting:

1. 81.2% annual energy savings

2. Reduced the number of lights from before by 47%

3. 78% annual CO2 savings / 277.20 tons of CO2 saved per year

Extra benefits from our LED solution:

1. ROI 2.5 Years

2. Visibility has improved since the daylight white light makes the colours and movements more easily perceived by the eye

Project: To improve the facilities light levels whilst reducing energy

The Brief -

Gregory Distribution are the largest member of the Gregory Group of companies which includes Hayton Coulthard, with whom they have a joint venture, which is headquartered in Kirkcudbright in Scotland. They all share a strong reputation for their standards of service which is emphasised by their complementary liveries.

For almost a century, Gregory Distribution have been proud to work with a wide variety of customers from local companies to large, multi-national organisations. Today, they serve over 400 customers based regionally, nationally and internationally.

On a distribution level, Gregory are the 'delivery winners' but their facilities lighting was draining maintenance and energy resources. Gregory Distribution required a new lighting solution that would improve light levels whilst reducing energy and maintenance costs.

In total, there were 908 existing lights. The majority of these were 140 watt 6ft twin fluorescents, but there were also 250 watt high bays, skylights, SON-T, 6ft single fluorescents, 5ft single fluorescents, 5ft twin fluorescents and bulkheads.

The Solution -

To replace these we installed a variety of our indoor and outdoor intelligent LED lighting across the whole of Gregory's site. Due to the higher lumen level and light output of our products we were able to significantly reduce the number of luminaires from before by 47%. The new indoor LED lights consisted of our LumiOPTIMA's, SmartROD's, Sky Panel 66 and LumiROD 4's. For the outdoor areas we used our SunSHINE floodlights.

Previously, the old indoor lights stayed on most of the day, even when there wasn’t any activity or low foot fall. Now, with our intelligent built-in sensors the lights come on when motion is detected and turn off after 5 minutes when there is no motion detected. In areas where there is access to natural light the sensors also provide Daylight Harvesting, which adjusts the light output according to the ambient (natural) light levels.

Prior to the installation of our new LED lighting we installed an energy monitoring system for 7 days to monitor the energy usage of Gregory's old lighting. After installation of our new LED lighting we then installed the same monitoring system again for the same 7 day period to monitor the energy usage and prove the energy savings achieved by the new LED lighting. The table below contains the actual testing results and savings achieved.

Installing our intelligent LED lighting solutions enables Gregory Distribution to adopt cutting-edge technology while reducing maintenance costs and increasing energy efficiency with improved illumination. With potential energy savings of £73,586.51 per year, the new LED lighting not only improves the quality of light, but helps save money.
