The LEED project boundary, as defined by the Minimum Program Requirements (MPRs), includes the land and water area that is reviewed for certification. This boundary encompasses all contiguous land and water under the control of the project owner that will be part of the certification process. The project boundary is critical because it delineates the area of development or land-use that will be assessed against LEED criteria.

Detailed Explanation:

LEED Project Boundary: The project boundary is a key concept in LEED certification, defining the precise area that will be evaluated for compliance with LEED criteria. It includes all land and water areas associated with the project that will be developed or impacted by the project activities.

Purpose: Establishing a clear project boundary ensures that all relevant environmental impacts, including those related to land use, water use, and infrastructure development, are properly accounted for in the certification process. It prevents any ambiguity about which parts of a development are subject to LEED standards.

Minimum Program Requirements (MPRs): MPRs are essential prerequisites that must be met for a project to be eligible for LEED certification. Defining the project boundary is part of these requirements, ensuring that the entire area under consideration is consistently and comprehensively reviewed.

The LEED Reference Guide for Neighborhood Development outlines how to define and document the project boundary.

The LEED v4 Neighborhood Development documentation provides specific guidance on the inclusion of land and water areas within the project boundary.

The Neighborhood Pattern and Design Credit for Reduced Parking Footprint aims to minimize the environmental impact associated with parking facilities and promote sustainable transportation options. Among the choices provided, the strategy of placing carpool spaces within 300 feet (90 meters) of building entrances is an acceptable strategy. This option encourages carpooling and reduces the total number of parking spaces needed, thereby supporting the overall goal of reducing the project's parking footprint. Off-street parking in front of buildings and large surface parking lots are generally discouraged as they contribute to sprawl and are less sustainable.

When using the whole building energy modeling option to determine compliance with the Green Infrastructure and Buildings Prerequisite for Minimum Building Energy Performance, the reference standard used is ASHRAE 90.1-2010. This standard provides the minimum requirements for energy-efficient design of buildings, excluding low-rise residential buildings. It is a widely recognized benchmark for energy performance in the United States and is used as the basis for LEED energy modeling requirements.

For the Green Infrastructure and Buildings Credit on District Heating and Cooling, single-family residences may be excluded from the district system if the energy savings from including them are negligible or if it is impractical to connect them. The LEED system recognizes that it may not be efficient or cost-effective to include single-family homes in a district energy system, particularly if they are spread out over a large area. Therefore, excluding them does not negatively impact the credit achievement as long as the overall system design meets the efficiency and coverage requirements for other building types.

LEED v4 Neighborhood Development Guide: Discusses the criteria for District Heating and Cooling credits, including allowances for excluding certain building types like single-family residences (USGBC, LEED v4 Neighborhood Development Current Version).

LEED Reference Guide for Neighborhood Development: Provides guidance on the conditions under which buildings can be excluded from a district energy system without affecting credit eligibility (USGBC, LEED Reference Guide for Neighborhood Development).

Using air conditioning condensate for flushing toilets in all new buildings directly contributes to reducing indoor potable water use, which is the focus of the Green Infrastructure and Buildings (GIB) Credit for Indoor Water Use Reduction. This credit encourages the use of alternative water sources, such as air conditioning condensate, to minimize the consumption of potable water for non-potable uses. By implementing this strategy, the project can demonstrate significant reductions in potable water use, thereby helping to achieve the credit.

LEED v4 Neighborhood Development Guide: The guide outlines the criteria for the Indoor Water Use Reduction credit, including the use of alternative water sources like condensate (USGBC, LEED v4 Neighborhood Development Current Version).

LEED Reference Guide for Neighborhood Development: Provides detailed guidance on achieving the Indoor Water Use Reduction credit through the use of innovative water management techniques (USGBC, LEED Reference Guide for Neighborhood Development).
