The Lighting Team studied how different room designs affect the amount of natural light inside. They changed things like room orientation and window size in computer simulations to see how it impacted the amount of daylight. They found that certain design features can increase the amount of natural light in a room, which can reduce the need for electric lighting. They also created a tool to help designers quickly see how their design choices affect daylight levels. They are now working on creating models to predict daylight availability and lighting energy needs in different spaces.
