CONTROLS OFFER LIGHT RELIEF with 40% energy savings
With new government legislation about to come into force, Dr Andy Davies of Harvard Engineering explains how wireless lighting controls can make light work of energy savings
T
he smart control of industrial lighting offers significant energy savings in a
sector where lighting can typically be powered on 24 hours a day, 365 days a year. Lighting is estimated to equate to 41% of commercial electrical consumption in the UK and is an obvious target for all companies aiming to make savings, particularly those subject to the Government’s Energy Savings Opportunity Scheme (ESOS) requiring larger enterprises to undergo a mandatory assessment of energy use and energy efficiency opportunities by December 2015. Using energy efficient LED lighting
along with smart control and management systems should already be saving industry millions of pounds a year and yet figures show that only 25% of all the controllable lighting currently sold in Europe is linked to any kind of control. Two factors may account for this.
Traditional lighting controls lack flexibility and require expensive and disruptive rewiring. Furthermore, controls are generally costly to commission and complicated to use. Both issues have been addressed by an award-winning control system from Harvard Engineering.
WEB-BASED CONTROL Designed, sourced and manufactured in the UK, EyeNut is a web-based, wireless control, monitoring and management system for indoor lighting that is easy to retrofit onto existing fittings and into new schemes. Intuitive and user-friendly, it gives companies the freedom to commission, configure and completely control their own lighting to maximise energy savings and reduce carbon emissions. Proven savings of up to 40% can be delivered on top of those gained by a switch to LEDs. Managing lighting in a factory can be
challenging, requiring compliance from staff, knowledge about what can and cannot be switched off and understanding the cost implications of leaving lights on. EyeNut takes over the responsibility of ensuring optimum lighting at all times. This system can implement a full range of energy saving strategies including
sensors, dimming and scene setting to ensure that lights are off during downtime and between shifts and provide the correct intensity for each area or task. It will ensure that light is reduced or switched off in unoccupied areas, supplement daylight only as necessary and sync exterior lights with daylight.
USER-FRIENDLY EyeNut allows users to manage and customise their lighting scheme using an intuitive user-friendly ‘dashboard’ or Graphic User Interface which can be accessed via a computer, laptop or tablet. All the light points, their status and energy spend are clearly visible on the screen and can be easily altered to meet energy targets. This reporting system is an essential
tool when complying with energy audits. A mapping feature gives the operator a clear and complete view of all light points set over an imported image of their building layout, making it easy to see energy ‘heat spots’ and specific energy consumption. EyeNut identifies devices via discovery or radio frequency identification (RFID) to operate lights individually or in groups. Devices are simply commissioned using
a RFID scanner. Up to 500 light points can be managed from a single gateway

Completely customisable, a profiling tool allows easily created area and logical groups to be controlled over assigned schedules
via a robust, secure ZigBee wireless mesh network. This compares favourably with the offer of 64 using DALI controls.
COMPLETELY CUSTOMISABLE Completely customisable, a profiling tool allows easily created area and logical groups to be controlled over assigned schedules which can be simple or sophisticated – with variations possible every 15 minutes, 365 days a year. There is no limit to the number of gateways or devices that can be linked to the system and this is why, for the first time, it is possible to operate lights for multiple buildings from a single cloud- based hub to offer maximum savings. Even emergency tests are simplified. A
new interface with emergency luminaires means that tests can be carried out when a site is empty or distributed throughout a building to minimise disruption. Test results automatically appear in the EyeNut interface and can be exported to external systems for audit tracking. With controls this easy, isn’t it time for
industry to come on board and make light work of energy savings?
