Case Studies Ex-Or meets the hot-desking challenge Lighting controls and management systems from Ex-Or are helping office managers introduce flexible working practices and productive environments into office workspace. Surveys have shown an increasing amount of “hot-desking”- workers sharing the same desk space; and of “churn”- the constant change in use and layout of office space. Ex-Or has designed lighting control systems that match this increased flexibility of office working. Now managers can not only benefit from the energy cost savings afforded by Ex-Or lighting controls, but can also introduce flexible office working practices more cost effectively. “Hot-desking makes lighting control even more desirable” Surveys show that flexible office workers can spend around 45 per cent of their working time on the move, away from their desks. Ex-Or office lighting management systems use presence detection to monitor occupancy, and automatically switch off the lights when office space is unoccupied. In offices where hot-desking is prevalent, desk space is used irregularly and often outside regular office hours. Presence detection lighting controls ensure lights automatically come on only when desks become occupied. Surveys also show the importance of creating an office environment that stimulates workers' productivity and performance. Constant optimum light levels have a significant part to play in creating the ideal working environment. Ex-Or's lighting controls and systems automatically dim or brighten the levels of light, and switch the lights on and off, taking into account both working activity in the monitored area and levels of daylight. “Office churn calls for flexible lighting systems” Increasingly, desks and workstations in open plan offices are moved around or changed in size to meet the ever changing needs of a dynamic company - so called “churn”. This means there is a frequent need to alter lighting systems to match the changed workstation layouts. This process normally involves hiring an electrician to alter cabling and switching, or having to carry out the complicated and time consuming process of reprogramming managed lighting systems via a PC. But with the Ex-Or MLS Managed Lighting System, the buildings and facilities manager just has to use a simple hand-held programmer to alter and set the programmable features within the MLS detectors. He just needs to point the programmer at the nearest luminaire and easily make the changes needed at the touch of a button. Changing levels of occupation and space usage (churn) at Yorkshire Water's three-storey office headquarters in Bradford led to the specification of the Ex-Or MLS Managed Lighting System. There was a need for regular re-configuration of the space occupied by different sections or departments. Every change has an impact on the lighting in each particular area, so Ex-Or's system was designed to cope with every eventuality.
