Transcript of Lighting Design of a Single Storey Residential Houseynamae
Description of the Project
This design shows the lighting and switching layout of a a 200 sq. meter single story residential house. It also includes the illuminance level of each room and the design of the luminaries that will be use on different parts of the house. It is also show the computation of the calculux and zonal cavity method.
Illuminance levels selected for each room/area
Living Area - 150 lux
Dining Area – 150 lux
Kitchen – 500 lux
Master Bedroom – 150 lux
Bedroom 1 – 200 lux
Bathroom - 150 lux
Laundry – 150 lux
Garage – 150 lux
Selection and Description of Luminaires
For Living Room: (Zonal Cavity Method)
Average maintained illuminance: 150 lux
Luminaire Data Lamp Data:
Manufacturer: Cooper Type and Color: Duplex Fluorescent with cover/ 35K
Number per luminaire: 2 pcs
Catalog Number: WN-232A Total lumens per luminaire: 3100 lumen per luminaire
Selection and Description of Luminaires
For the Bedroom (Using Calculux)
Average Maintained Illuminance: 200 lux
Luminaire Data Lamp Data:
Manufacturer: Philips Type and Color: Recessed Downlight / Cool White (840)
Number per luminaire: 1
Catalog Number: QL55W Total lumens per luminaire: 3500 lumen per luminaire
CCR=5(0)(3.7+5.4)/(3.7)(5.4)

SELECTION OF LIGHT LOSS FACTOR
Non recoverable Luminaire ambient temperature
= 0.80
Voltage to luminaire = 0.95
Ballast factor = 0.88
Luminaire surface depreciation = 1.00
Total LLF = 0.80 x 0.95 x 0.88 x 1.00 x 0.98 x 0.85 x 0.90 x 0.92
Total LLF = 0.46
Recoverable Room surface dirt depreciation =
0.98
Lamp lumen depreciation = 0.85
lamp burnout factor = 0.90
Luminaire dirt depreciation = 0.92

Calculations
Average Maintained Illuminance
No. of luminaire = (Illuminance x Area) /
(Lumens per luminaire x CU x LLF)
vv = 150 lux (3.7m x 5.4m) / (3580 lm per luminaire x 0.75 x 0.464 x2lamp per luminaire)
= 1.2
= 2 luminaires
ILLUMINANCE
Illuminance = No. of luminaire x lumen per luminaire x CU x LLF x lamp per luminaire / Area
= 2 x 3580 x 0.75 x 0.46 x 2/ 3.7 x 5.4
= 249.4
= 250 lux
