A fourth aspect of green building technologies that can promote sustainable transportation is the enhancement of indoor environmental quality in the building. Indoor environmental quality refers to the physical and psychological comfort and well-being of the building occupants, which can be influenced by factors such as temperature, humidity, air quality, lighting, noise, and aesthetics. Green building technologies can improve indoor environmental quality by using natural and low-VOC (volatile organic compounds) materials, providing adequate ventilation and filtration, controlling thermal and acoustic comfort, and creating biophilic and ergonomic spaces. By improving indoor environmental quality, green building technologies can also increase the satisfaction and productivity of the building occupants, which can motivate them to adopt more sustainable transportation behaviors, such as telecommuting, carpooling, or cycling.
