Detailed
The LEED boundary for Phase 1 can include only the building site (Phase 1) but must commit to keeping the Phase 2 grounds undisturbed until the second phase begins. This approach aligns with LEED's requirement to define boundaries where work occurs and ensures environmental protection for future development areas.

For the Sustainable Sites (SS) Prerequisite: Construction Activity Pollution Prevention, a compliant Erosion and Sedimentation Control (ESC) plan can be developed or modified during the design phase of LEED certification (B). This flexibility allows the project team to adjust the plan as needed to ensure proper site protection measures before and during construction. An ESC plan is essential to prevent soil erosion, waterway sedimentation, and airborne dust, aligning with LEED's environmental protection standards.

Large commercial buildings are most often dominated by internal loads, which are the heat gains or losses from people, equipment, lighting, and other sources inside the building. Internal loads can affect the heating and cooling loads and the energy consumption of the building. Therefore, reducing internal loads can improve the building's energy efficiency and performance.

According to the LEED v4: Building Design + Construction Guide, the Location and Transportation Credit, Access to Quality Transit has two options: Option 1. Transit-Served Location and Option 2. Transit Service Quality. Option 1 can earn 1 to 4 points depending on the percentage of functional entries within walking distance of transit stops or stations. Option 2 can earn 1 point if the project meets the minimum weekday and weekend headways for bus, streetcar, or informal transit stops, or rail stations or ferry terminals. The maximum number of points a project can achieve under this credit is 4 points by meeting both options1.

Private lavatory faucets are eligible for a WaterSense label, provided they meet EPA's specifications for water efficiency and performance, and are backed by independent, third-party certification. Tankless toilets, waterless urinals, and public lavatory faucets are not eligible for a WaterSense label because they are not included in the product categories that WaterSense covers. WaterSense currently labels products in the following categories: tank-type toilets, water-using urinals, private lavatory faucets, showerheads, irrigation controllers, spray sprinkler bodies, and pre-rinse spray valves.
