Lighting and Daylighting design objectives are for well-being, culture , and sustainability to become a leading airport for the 21st century at a limited budget. Working with the HOK architect from design concept and trying to integrate it into the final design was quite a challenge in terms of the balance between the utilization of natural light, visual perception, energy-efficient, risk of water leakage, and cost.   BioArchitek also advised contractors on lighting operation schemes integrated with daylight and human behavior during the programming / commissioning phase.
