COLOUR RENDERING INDEX (CRI): 100 COLOUR TEMPERATURE (CCT): 5500K LUMINANCE: 1405 LUX CONSTANT VARIABLES: ISO: 160 APERTURE: F/2.2 SHUTTER SPEED: 100 WHITE BALANCE: 2700K VISUAL PROVIDED SHOWS THE COLOUR PYRAMID TAKEN AT 5PM ON A CLOUDY DAY. CONSTANT VARIABLES REMAIN SAME AS THE INDOOR EXPERIMENT CONDUCTED. DAYLIGHT ANALYSIS IS USED AS A REFERENCE FOR THE LAB EXPERIMENT FOR THE INDOOR ARTIFICIAL LIGHTING EXPERIMENT CONDUCTED. OBSERVATION: APPEARANCE OF THE COLOUR PYRAMID IS CAREFULLY OBSERVED UNDER THE RIGHT EXPOSURE OF OUTDOOR DAYLIGHTING. WITH REFERENCE TO THE VISUAL PROVIDED, THE COLOURS OF THE PYRAMID ARE SLIGHTLY RENDERED UNDER PRESENCE OF DAYLIGHT. HOWEVER, THE COLOUR TONE BELOW VIOLET BECOMES NON-DISTINCTIVE

OBSERVATION

ANALYSIS BY OBSERVATION 1. BASED ON OBSERVATIONS CONDUCTED, ARTIFICIAL LIGHTS ARE FOUND TO HAVE SIMILAR COLOLUR TONES AS DAYLIGHT TEMPERATURES. 2.HALOGEN FLOOD LIGHT IS SEEN TO HAVE THE BEST CORRELATED COLOUR TEMPERATURE WHEN COMPARED TO OTHER LIGHT SOURCES AVAILABLE, THIS ALLOWS FOR COLOUR TONES ON THE COLOUR PYRAMID TO BE EASILY DISTINGUISHED. 3. ARTIFICIAL LIGHT WITH AVERAGE OR POOR COLOUR CRI AND CCT WILL PRODUCE DARKER RENDERINGS WHICH IN RETURN CAUSES COLOURS OF THE PYRAMID TO BE HARD TO IDENTIFY4. WHEN COMPARED BETWEEN COOL DAYLIGHT (6500K) AND WARM WHITE (2700K),THE COOL DAYLIGHT PRODUCES A MORE BLUE-ISH TONE WHILE WHITE PRODUCES A MORE REDDISH COLOUR TO THE COLOUR PYRAMID CONCLUSION TO CONCLUDE, THE COLOUR TEMPERATURE (CCT) AND COLOUR RENDERING INDEX (CRI) PRODUCED BY DIFFERENT TYPES OF ARTIFICIAL LIGHT SOURCES REMAIN NOT UNIFORM. ARTIFICIAL LIGHTS WITH SIMILAR CCT OR CRI DO NOT PROVIDE THE SAME COLOUR EFFECT AS PROJECTED ON THE PYRAMID.

ORCHARD ROAD, SINGAPORE THE SUN PATH ON ORCHARD ROAD FLOW CENTRALLY, IN A WAY THAT THE NORTH POINT IS ADJACENT TO THE FLOW OF THE ROAD MAKING THE LIGHTING FROM THE SUN NOT AS AFFECTIVE AND BRIGHT AS SITE B IN CHOW KIT, ROAD. THE SHOPLOTS ARE NOT AS EXPOSED TO THE SUN PATH NOR DOES IT INTERSECT THE BUILDINGS DURING SUNRISE, NOON OR SUNSET. MOST OF THE SHOPLOTS ARE MOSTLY LIGHTED BY ARTIFICIAL LIGHTING ESPECIALLY WHEN THE SHOPLOTS ARE SURROUNDED BY HIGH-RISE BUILDINGS INCLUDING SHOPPING MALLS AND OFFICE TOWERS. SOME OF THE BUILDINGS ARE ACCESSIBLE THROUGH THE UNDERGROUND, INCREASING THE NEED OF ARTIFICIAL LIGHTINGS AND SOME BUILDINGS ARE DESIGNED TO BE DOUBLE VOLUME AT THE FRONT ENTRANCE TO COUNTER THE LACK-NESS OF LIGHTS IN THE AREA.

PRECEDENT STUDIES

NOISE REFLECTION AND STRATEGIES 10 A.M. -TRAFFIC CONDITION STARTS TO BUILD UP ALONG THE MAIN ROADS. -PEDESTRIAN CIRCULATION AROUND THE SITE IS MEDIUM WITH MOST OF THE TRAFFIC IS FOCUSED TOWARDS THE MONORAIL -THIS CAUSES MEDIUM LEVEL OF NOISE TOWARDS AND AROUND THE SITE 12 P.M. -THERE IS A HEAVY FLOW OF HUMAN TRAFFIC AROUND THE SITE INCLUDING THE BACK ALLEY DURING THIS TIME DUE TO IT BEING LUNCH PERIOD. -VEHICULAR CIRCULATION IS EQUALLY AS HEAVY DURING THIS PERIOD AS WELL -DURING THIS PERIOD, NOISE LEVEL IS AT ITS PEAK

THE SITE IS LOCATED NEARBY A MONORAIL STATION IN ADDITION TO SURROUNDING HIGH-RISE BUILDINGS HENCE ACOUSTIC REFLECTIONS ARE HIGHLY APPARENT WITHIN THE SITE. REVERBERATIONS DUE TO NEARBY STRUCTURES WILL BE APPARENT AS WELL. ALSO, GIVEN THE SITE’S LOCATION ON A LOW LEVEL, NOISE LEVEL ARE EVEN MORE OBVIOUS. WITH PEDESTRIAN, VEHICULAR CIRCULATION AND ALSO THE MOVEMENT OF THE MONORAIL WITH THE OCCASIONAL NOTIFICATION FROM THE STATION, NOISE FROM THESE ACTIVITIES ARE AMPLIFIED MORE THROUGH ACOUSTICAL REFLECTION AS A RESULT OF THE PLACEMENT OF NEARBY BUILDINGS.

BY UNDERSTANDING POSSIBLE REFLECTION PATHS, MEASURES CAN BE TAKEN TO AVOID SUCH UNDESIRABLE NOISE LEVELS.

5 P.M. -HUMAN TRFFIC IS NOT AS HEASVY AS DURING THE AFTERNOON. HOWEVER, FLOW OF TRAFFIC ARE MOSTLY FOCUSED TOWARDS THE MONORAIL AS THIS TIME MARKS THE END OF WORKING PERIOD FOR MOST PEDESTRIAN. -VEHICULAR CIRCULATION MAY BE CONGESTED DURING THIS PERIOD MOVING AWAY FROM THE SITE. -NOISE LEVEL IS EQUALLY AS HIGH AS DURING THE AFTERNOON. 9 P.M. -THERE IS LOW READING OF ACTIVITIES FOR BOTH HUMAN AND VEHICULAR CIRCULATION DURING NIGHT TIME. -THUS, NOISE LEVEL IS LOW DURING THIS PERIOD.

NOISE SOURCE

NOISE IS RELECTED BETWEEN THE MONORIAL STATION AND SITE B VEGETATION SERVES AS A TRANSITIONAL SPACE BETWEEN THE TWO MASKING UNWANTED NOISE

PRECEDENT STUDY IN A COMPARABLE CASE, SINAGPORE’S ORCHARD ROAD IS SOME WHAT SIMILAR TO MALAYSIA’S CHOW KIT ROAD WHERE OUR SITE IS LOCATED. ORCHARD ROAD HAS ONLY BEEN AROUND AS LONG AS CHOW KIT OR MAYBE EARLIER. HOWEVER, THE IMPLEMENTATION OF STRUCTURAL MATERIALS THAT ABSORBS SOUND IS FAR MORE FREQUENT. DESIGN STRATEGIES SUCH AS PROVIDING A LARGER SET BACK FROM THE ROAD REDUCES NOT ONLY THE CONSTANT REFLECTION OF SOUNDS FROM HUMAN AND VEHICULAR BUT THIS STRATEGY ALSO ALLOWS FOR A LESS DENSE CITYSCAPE. HENCE, LOWERING THE FREQUENCY OF SOUNDS ALL AROUND.
