Final answer:
LEED considers a room or space 'dense' when it has a high density of occupants. Density is used to evaluate efficiency and sustainability of a building's design and operation.
Step-by-step explanation:
In the context of LEED (Leadership in Energy and Environmental Design) for buildings, density refers to the number of people or occupants per unit area of a room or space. LEED considers a room or space to be 'dense' when it has a high density of occupants.
For example, if a classroom has a capacity of 30 students and the room is consistently occupied by at least 25 students, it can be considered a dense space according to LEED standards.
Density in this context is used to evaluate and assess the efficiency and sustainability of a building's design and operation.
