Energy Efficient Lighting- Solutions for Offices Independent research intimates about 40% of all the energy devoured in structures is used for lighting. So, if you want to reduce the electricity consumption in your office and switch to force efficient igniting what options do you have? Well energy efficient illuminating is an association of the following 6 causes. Firstly the lamp or the light source itself. You should use a lamp which provides the highest level of daylight for the lowest of electricity consumption, we call this the lumen per watt rate. This efficiency rate should also be maintained during the lifetime of the lamp, this is known as lumen upkeep. It’s also important to have the right amount of light.

The quality of the light should also fit the application, for example in agencies Philips recommends a colour rendering of above 80. The second relevant cause is the ballast, switching from traditional electro magnetic ballasts to new electronic ballasts will save up to 25%. The third influence is the use of lighting commands. These are simple devices which turn off or dim down the lighting when people are no longer present, saving up to 30%. Other controls can dim the brightnes when enough natural sunlight is present, which provides for additional energy savings of up to 30%. The fourth ingredient is the luminaire or more particularly the optics. The light output rate indicates how force efficient a luminaire is for example by switching from traditional extend luminaires to state of the art lumella luminaires you can save more than 50%. In add-on the optics should lead the light to the places where it is needed and escape glare, for example in agency igniting a delta shaped beam in well-liked. The fifth cause is the igniting layout. This pattern should be based on the right lighting grade , not too high , not too low. The lighting should be uniform to avoid dark smudges and take into account the colour of the walls and carpets.

In fact a poor lighting design can use up to twice as much vigor as a good one. The sixth and final ingredient is utilization and maintenance, for example different groups replacement of lamps should be used and the luminaires themselves should be cleaned regularly and switch off the lighting when it’s not needed.

This audit should result in a figure for the watts actually used by the installed illuminating per square meter in its term of office. If the above figures is more than 30 watts per square meter, which is common in traditional offices you have very inefficient lighting and hence plenty of opportunity to save vitality. Between 15 and 30 watts per square meter you have a lot of interesting options for saving energy, whilst between 8 to 15 watts per square meter you still have options for example by using igniting controls.

Less than 8 watts per square meter means your igniting is already vigour efficient by today’s standards. Ok , now tells assume that you have done this exercise and you know there is a lot of potential for energy savings, you have three main options. First is a full renovation, blending all 6 of key factors just mentioned, second is a one to one luminaire replacing of your current systems and thirdly, an element permutation which represents either supplanting the lamp or contributing simple-minded control systems. The first option, a full redevelopment, offers the largest potential energy savings and hence the greatest cost savings during the lifetime of the lighting.

This involves a new lighting layout which can often shorten the amount of light fittings requirement. Such a new layout allows you to use state of the art vitality efficient igniting answers. For general lighting in the working places these include TL5 fluorescent lighting, which are the most efficient solutions available today. Solutions here include the Philips Smartform with its very high optic efficiency of up to 95% and it’s state of the art Actilume lighting governs, up to 80% energy savings.

Another runner here is the TBS2 57 which provides for energy savings up to 60%. For general lighting in corridors and fulfilling areas in addition to using TL5 fluorescent solutions you could also consider a new generation of downlights. Answers here include Fugato and LED solutions like the Philips LuxSpace downlight assortment which offer energy savings of up to 50%. For accent and more decorative results you can consider solutions such as SpotLED, CoveLED and Fugato with muster colour lamps. Savings here can reach up to 80% compared to Halogen solutions.

These progress will allow you to reduce the number of members of lamps and hence energy consumption you need, although the light sum and caliber should adopt measures stand or increase, tells look at some examples. In many offices the general igniting are offered by traditional luminaires with 4 x 18 watts TLD lamps equipped with a treat optic or a simple reflect louver and operated by an electro magnetic ballast.

These luminaires can be replaced on a one to one basis for example by a Philips Smartform luminaire with 3 x 14 watts TL5 lamps and furnished with a very highly efficient mirror optic. By doing this the energy consumption is shortened from 92 watts to 48 watts saving 48% on the energy consumption. When the new luminaire is equipped with a Luxsense daylight sensor additional savings of 30% are realised bringing the full amounts of the savings up to 65%. Even better is to equip the luminaire with Actilume holds and draw the full amounts of the savings up to 80%. Another instance are the traditional dicroic halogen spots with electromagnetic transformer which can also be replaced with Philips SpotLEDs reducing energy consumption from 56 watts to 12 watts saving 80% of energy.

An additional benefit is the huge gain in lamp lifetime from 2000 hours for the halogen lamp to 50000 hours for the LED solution. Your third and final alternative for switching to vigour efficient lighting involves changing the lamps and contributing simple-minded controls to your existing lighting, there are various alternatives here too.
