SPACE A CALCULATIONSDISCUSSION ROOMS

According to MS1525, daylight factor distribution is as below:

Zone Daylight Factor (%) DistributionVery Bright >6 Too bright with thermal and

glare problemsBright 3 – 6 GoodAverage 1 – 3 FairDark 0 – 1 Poor

DAYLIGHT FACTOR CALCULATIONFloor Area (m2) 3.6 x 7.3 = 26.3Area of façade exposed (m2) 3.3 x 3 = 9.9Daylight factor 9.9 / 26.3

= 0.38= 38% x 0.1= 3.8%

NATURAL ILLUMINATION CALCULATIONLuminance Level (Lux) Example

120,000 Very bright sunlight110,000 Bright sunlight20,000 Clear sky1000 – 2000 Overcast day400 Sunrise/sunset on clear day<200 Midday40 Fully overcast<1 Sunset, storm cloud

DF = E.Internal / E.External x 100%= (3.8 x 20,000) / 10= 760 lux

LUMEN METHOD CALCULATIONDimension of room (L x W) 3.6 x 7.3Floor area (A) 26.3Height of ceiling (m) 3Required lux (lux) 500Luminous flux (lm) 900Height of luminaire (m) 3Height of work level (m) 0.7Mounting height (Hm) 2.3Reflection factors Ceiling: 0.7

Wall: 0.5Room index (K) 3.6 x 7.3 / 2.3 (3.6 + 7.3)

= 1.05Utilization factor (UF) 0.4Maintenance factor (MF) 0.8Number of Lamps required 500x 26.3 / 900 x (0.4 x 0.8)

= 4.6= 5 lamps

Spacing to height ratio (SHR) 1.5 x 2.3= 3.45

Fittings Layout Fittings required along wall = 7.3 / 3.45= 2 rowsNumber of lamps in each row = 5 / 2= 2.5= 3 lampsSpacing along wall = 3.6 / 3= 1.2m

Fitting layout of the light fixtures in the chosen space.
