Which of the following options qualifies as outdoor space according to LEED guidelines?

Outdoor space, as defined by LEED guidelines, specifically refers to areas that are accessible and suitable for outdoor activities, particularly those that contribute to the health and well-being of building occupants. The correct answer highlights the importance of spaces designed for social interaction or recreational use. Paving or turf that accommodates outdoor social activities effectively meets this criterion, as it encourages outdoor use, enhances community engagement, and promotes healthier lifestyles.

In contrast, options like areas with trees may contribute to environmental quality, but without the functional aspect of accommodating planned activities, they don't fully qualify as usable outdoor spaces according to LEED standards. Buildings with rooftop gardens, while potentially beneficial, are not classified as outdoor space unless they explicitly provide access and are designed for use by occupants. Similarly, indoor spaces with large windows do not constitute outdoor space; they offer views of the outdoors but do not provide the opportunity for outdoor access or activities. Thus, the focus on usable outdoor areas designed for social interaction makes paving or turf that accommodates outdoor social activities the only option that fully aligns with LEED outdoor space criteria.
