26. 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.
