Atrium daylighting
-
Tannenbaum reflector panel on levels 4 and 5 Atrium Daylight Design
The atrium has been carefully designed optimize daylight utilization for each floor employing the combination of the following three strategies: 1. Automated blind with six different configuration to maintain the appropriate daylighting levels at all times. The blinds with 30% light
transmittance are adjusted every 15 minutes and follow a three different control strategies for morning, mid-day and evening 2. The windows size becomes larger deeper into the atrium to cater for lower daylight levels 3. A band of Tannenbaum reflector panels are applied to 4th and 5th floor to deflect daylight across the atrium to 1st and 2nd floor where daylight
levels are the lowest. The ‘christmas tree’ profile reflectors have an inclination of 10° and reflect about 85% of the light in semi-diffuse manner, hence, avoiding visual glare issues for the building occupants.

Façade daylighting
-
Self-shaded facade from direct sun
Diffuse light deflected into room by lightshelf and window sill LIGHT REFLECTIONS FROM:
Lightshelf + Window sill
Lightshelf only
Window sill only
Mirror lightshelf with fixed louver
Façade Daylight Design The building is 50% daylit. The façade daylighting system consists of a mirror lightshelf and a white painted window sill. Both deflect daylight onto the white ceiling for improved daylight distribution until 5 meters from the façade + 2 additional meters of corridor space. Installed office lighting is 8.4 W/m2, but 1-year measurements show consumption of only 4 W/m2 showing 50% reliance on daylighting

Suspended Ceiling
Advantages by removing suspended ceiling • Allows floor slab cooling system to work • Allows deeper throw of daylight • Allows easier maintenance • Gives loftier & nicer office space
