4- Efficient Lighting Design: (Cont.)

     When considering another design for the same area using a fixture from the same family of the previous used fixture; i.e. having the same exact characteristics, but with 4x14W lamps, as shown in Fig. (Working space lighting using 4x14W fixtures). The lighting results are as follows: 506 average lux, 0.68 uniformity and the total consumed power is 650W.

 

another lighting solution for the same office area but using appropriate lighting fixture

As the standard average lux should be 500 lux at workplane for office lighting, we can conclude that using the appropriate fixture led the design to make almost 12% of energy savings, and at the same time did not stoop any other lighting parameter, but on contrary raised the uniformity factor.
