Summary
Lighting:•The spaces draw students in while providing a relaxing and open
experience and meeting IESNA and ASHRAE standards.
Daylighting
•The Study Lounge offers quality daylight levels throughout the
day.
Thermal Analysis
•The additional shades reduce the solar load and overall
cooling load of the study lounge.
Electrical
•Direct Coupling is more effective then inverter based
systems.
