According to the LEED v4: Building Design + Construction Guide1, Option 2 of the Surrounding Density and Diverse Uses credit requires the project to be within walking distance of at least 10 diverse uses. The guide also states that “walking distance is defined as the distance that a pedestrian must travel between origins and destinations without obstruction, in a safe and comfortable environment on a continuous network of sidewalks, all weather-surface footpaths, crosswalks, or equivalent pedestrian facilities.” Therefore, the documentation must include walking routes from the project to each use to demonstrate that the distance requirement is met. References:

According to the LEED v4: Building Design + Construction Guide, the bicycle network must connect to a rapid transit stop that is within 3 mi. (5 km) biking distance of the project boundary. This is one of the options to meet the requirement for Option 1: Bicycle Network and Storage. The other options are to connect to at least 10 diverse uses or to connect to a school or employment center that is within 3 mi. (5 km) biking distance of the project boundary. References: LEED v4: Building Design + Construction Guide, Location and Transportation Credit: Bicycle Facilities, Option 1: Bicycle Network and Storage1

ENERGY STAR® (C) provides tools recognized by the U.S. Green Building Council (USGBC) that assist with energy management strategies, benchmarking, and procurement guidelines. ENERGY STAR offers resources for energy performance benchmarking, operational efficiency, and product standards, which help project managers optimize energy use in line with LEED requirements. Green Seal (A) and SCAQMD (B) focus on materials and emissions, while SMACNA (D) provides guidelines for air quality management.

The Water Efficiency Credit, Indoor Water Use Reduction aims to reduce indoor water consumption by installing water-efficient fixtures and fittings, such as faucets, showerheads, toilets, and urinals1. A commercial dishwasher that is ENERGY STAR® labeled or performance equivalent would help reduce the water use for dishwashing, which is one of the process water uses included in the credit calculation2. A standard garbage disposal would not reduce water use, but rather increase it. An electronic submeter at the domestic water supply pipe to the building would help measure and monitor water use, but not directly reduce it. An open-loop HVAC system that discharges potable cooling water to a nearby lake would waste a lot of water and potentially harm the environment.
