Commercial Applications for Daylighting
1 like1,717 views
The document outlines strategies for optimizing daylighting in building design, emphasizing the importance of prioritizing daylighting, starting early in the design process, and implementing automatic controls. It discusses various lighting techniques, including both toplighting and sidelighting, and highlights the necessity of commissioning and educating building occupants about daylighting systems. Additionally, it references LEED credits and standards related to daylighting to ensure adequate natural light in occupied spaces.
