Final answer:
The SSc Open Space is a LEED credit that requires a project to have outdoor space greater than 30% of the total site area and that space must be accessible and designed for use by all building users.
Step-by-step explanation:
The SSc Open Space refers to a credit category within the Leadership in Energy and Environmental Design (LEED) system, specifically aiming to promote sustainable site development. To achieve this LEED credit, there are two main requirements: The project must provide outdoor space that is greater in area than 30% of the total site area (including the building footprint), and this space must be open to the sky. The outdoor open space must be accessible to all building users, provide a variety of amenities, and be designed to encourage active or passive use. Meeting these requirements provides benefits such as improved air quality, increased opportunities for social interaction, and physical activity, and contributes to the overall aesthetic and environmental quality of the development.
