WIRELESS LIGHTING CONTROLS generates up to 50% savings
When installed alongside the latest wireless indoor control technology energy efficient LEDs can deliver savings of up to 50% explains Andy Davies from Harvard Controls
he lighting controls market is set to double by 2024 as outdated fluorescent lighting is upgraded to energy efficient LEDs. For too long factories have been paying a high price for lighting which can typically account for nearly 50% of the electricity bill. Now, facilities managers are turning to wireless controls to cut those costs with the bonus of gaining a diverse range of energy saving strategies while reducing carbon emissions. When used with LEDs the latest controls are generating impressive savings of up to 50%. They have overcome the difficulties associated with traditional indoor controls including DALI and Analogue 1-10V which need to be wired-in and subsequently commissioned by a specialist engineer and offer no flexibility for altering patterns of use. Crucially, they lack a monitoring and

reporting system which is increasingly essential for companies wanting to maximise energy efficiency and savings. However, although the savings can be impressive only around 30% of all indoor lighting sold in Europe today is controlled by anything other than an on/off switch. This is changing with the lighting controls currently on the market offering huge improvements over traditional controls and the sector is predicted to outperform all other lighting product markets in the next few years.
WIRELESS CONTROL Harvard is helping drive forward the lighting control revolution having built a reputation for the design, development and manufacture of ground-breaking energy saving lighting solutions. EyeNut, the company’s wireless control and monitoring system for indoor lighting, is easy to install and maintain, allowing the user to take full control of the lighting of multiple sites from one intuitive interface. Lighting can be controlled and monitored on any computer, laptop, tablet or smartphone from anywhere in the world. The control system can be integrated with sensors and switches which give it a diverse range of energy saving strategies including daylight harvesting, occupancy and presence

monitoring. Its PIR technology allows for even further energy and cost savings. The pioneering EyeNut technology
mirrors that developed by Harvard for outdoor controls. Now an established technology, the company’s LeafNut system has been installed by more than 100 local authorities across over 400,000 light points around the world including London where it is installed in 15,000 of the Westminster’s street lights and is expected to help save the council £20 million over the next 20 years. Outdoor lighting is managed over the
internet using GPS and radio frequency identification and dimmed between set times at certain locations to ensure that only light is used as and when it is needed. Both LeafNut and EyeNut provide a two-way flow of information which includes details of lamp faults and reporting on energy usage which is a vital aid with the ever-increasing

pressure to meet energy targets. The success of outdoor controls is a further factor which will drive forward the revolution in indoor lighting controls now that the case is proven that future-ready solutions can be easily installed.
KEY ROLE FOR LIGHTING
Lighting has a key role to play in ensuring the world moves toward a low carbon economy demanded by central and local governments. The Carbon Trust which advises governments and businesses on the opportunities for a sustainable low carbon world accepts that upgraded lighting controls can cut costs and energy by up to 50%. Now is the time to assess current and future demand for lighting with recent statistics showing that up to 80% of the buildings which will be in use in the UK in 2050 are already built. Action is needed to make these sites more energy efficient while giving the building operator greater control over lighting to suit activities. With investment of lighting controls leading to a significant cut in electricity bills, a reduction in carbon emissions, more control and payback in as little as two years it’s easy to see why analysts are predicting such rapid growth for the sector.
