Make sure that all vegetated and hardscape open spaces are included in the LEED site boundary, and that the boundary for this credit is consistent with the boundary for all LEED credits.
Define your LEED project boundary to determine how much area you must designate as open space. The LEED project boundary encompasses a contiguous area that includes all areas affected by the project pursuing certification. Refer to the Rating System document (p. xvii) for specific guidelines on how this is determined. (See Resources.)
Discuss the potential for future build-out, and make sure the areas delineated as open space for credit compliance will not be compromised in the future. Consider creating a project master plan that includes long-term plans for open space, helping you comply with SSc9: Site Master Plan.
Discuss the potential for future build-out and make sure the areas delineated as open space for credit compliance will not be compromised in the future.
Research your site’s zoning requirements to see if you are required to provide open space; this will help you determine how much open space is required for credit compliance. The compliance path you follow is not open to choice—it depends strictly upon your local zoning regulations.
Your model must indicate the room-by-room airflow rates predicted by the analysis and demonstrate that 90% of the occupied building areas are effectively ventilated by natural means to provide the minimum ventilation rates required by ASHRAE 62.1-2007.
You may also provide the same information required for Option 1 in the format of a macroscopic, multi-zone, analytic model that predicts room-by-room airflow rates.
