Over Illumination Considered

Over illumination does not sound like a particularly serious issue at first, and indeed, it is not. However, every little bit adds up in these times of reduced economic confidence, and the amount of money that is being forgone by not paying attention to this issue can actually be rather considerable. Essentially, over illumination occurs when the amount of artificial lighting in an area is excessive for the task that is being performed. While this may seem minor, there are in fact several negative effects that this can have on health and productivity, and the savings that can be made from utilising more effective office fit out companies Sydney to reduce lighting to a more suitable level can be considerable. In fact, it is estimated that as much as forty per cent of the electricity use in the typical commercial office comes from lighting, so cutting down in this area where appropriate can reduce energy costs for a business. While obviously for reasons of common sense as well as occupational health, safety, and welfare you do not want people to be working in the dark, there are several situations where the amount of artificial lighting in an office could sensibly be reduced:

•    Unused areas are being lit when no one is in them
•    Artificial lighting is being used where office fit outs could allow for greater use of natural light that is available
•    Use of artificial lighting that is excessively intense – this can also reduce productivity, as overly bright artificial lighting, especially from the fluorescent tubes that are common in many offices, has been shown in studies to reduce the speed with which many people work
•    Too few light switches exist so that lights cannot be turned off when not in use – this is not easy or cheap to address after the fact, but it is still a major contributor to over illumination in many offices. For example, the iconic.

Marin County Civic Center building, which was designed in a striking modernist style and has been featured in many Hollywood films, only has one or two light switches per floor. This has been reported to cost the building’s occupants tens of thousands of dollars per year in excessive electricity costs because it is impractical to turn off lights that are going unused at any time. While architectural or building design issues that lead to over illumination are essentially impossible to address after the fact except at considerable cost, However, a provider of facilities management services can provide advice to address issues of illumination that are due to the fit out of the office and the location of employees and work stations within the office, and this can reduce energy costs and boost productivity as well as mitigate potential health effects that occur due to excessive lighting such as increased incidence of migraine head aches.
