Unipart - NHS Supply Chain warehouse

Background

NHS Supply Chain is the internal organisation that manages the sourcing, delivery and supply of health care and food products to the NHS and healthcare organisations in England and Wales.. The 152,000 sq ft warehouse in Normanton is operated by Unipart. It is an older building with a conventional, hard-switched lighting installation that had to be upgraded for performance and energy efficiency.

Challenge

The objective of the client was to improve lighting levels, save energy and have automatic testing and monitoring of emergency lighting.

The installation was to be done point-for-point, so no rewiring and creation of new electrical points would be required.

Solution

The Mymesh wireless control system was chosen to provide connectivity across the large building. All the new highbay and lowbay luminaires were equiped with a Mymesh wireless node, avoiding adding control wires in the building. Furthermore, battery-operated Highbay PIR sensors with a 10+ year battery life were used. The placement of the sensors was flexible as no mains connection was required.

Each aisle is now controlled by PIR, so energy can be saved when the area is not being used.

The Lumitel platform offers the possibility to use different light levels at different times of the day. This was the lighting can stay on at a low level when an area is in 'absence' and quickly ramp-up before an operator enters the area. During the evening and weekends the lightlevels can be dimmed further or switched off.

The Lumitel dashboard provides an easy portal for the client to monitor the site for energy consumption, faults and emergency lighting reporting. The operation of the lighting can be changed should the times of the work shifts change.

Benefits

On top of the energy savings achieved by the upgrade from conventional lighting technology to LED, the control element delivers an additional energy saving that positively impacts the operational carbon footprint of the site.

The wireless technology also has a large impact on the embedded carbon as no new and additional wiring was required.

The remote monitoring brings savings for maintenance and for external services for doing monthly and yearly emergency lighting flick tests.
