Building green can improve the indoor environmental quality (IEQ) of a building, which is the physical and psychological conditions of the indoor spaces that affect the health, comfort, and productivity of the occupants. Building green can enhance IEQ by using low-emitting materials, providing adequate ventilation, controlling temperature and humidity, optimizing daylighting and lighting quality, reducing noise levels, and promoting occupant well-being12.
