The building simulation company IES Virtual Environment (IESVE) has used one of our office building projects, Mercu Mustapha Kamal (Menara MMK), as a case study to showcase the daylight simulation capabilities of the Radiance module within the IES software. For this project, we undertook extensive daylight simulation optimizations to create the first "Daylight Trough" (or daylight duct) for high rise office buildings. The "Daylight Trough" runs above the suspended ceiling and drops daylight 3.5 meters into the space. This way, the first 7 meters of the facade perimeter can be fully daylit, even though people fully close the blinds along the facade.
