LEED-AP-BD+C Exam Questions Tutorials

A charrette is a collaborative design process that involves multiple stakeholders, such as the owner, the design team, the community, and the users. By including the public in a charrette for a new school before the pre-design phase, potential partnerships with the community can be revealed. For example, the school might share facilities or resources with a nearby library, park, or community center. This can enhance the social and environmental benefits of the project, as well as reduce costs and increase efficiency.

The Sustainable Sites Credit, Site Assessment requires the project to conduct and document a site inventory and analysis that evaluates the existing conditions and features of the site, such as topography, hydrology, human use, climate, vegetation, soils, and human health effects1. The purpose of the site assessment is to inform the design and development of the site in a way that protects, restores, and enhances the environmental quality and performance of the site1. The site assessment should include the following elements:

Topography: The shape and elevation of the land surface, including slopes, drainage patterns, and erosion potential.

Hydrology: The movement, distribution, and quality of water on the site, including surface water, groundwater, precipitation, and runoff.

Human use: The current and planned use of the site and its surroundings, including zoning, land use, transportation, utilities, and cultural resources.

Climate: The long-term weather patterns and conditions of the site, including temperature, humidity, wind, solar radiation, and precipitation.

Vegetation: The types, distribution, and condition of plants on the site, including native, invasive, and endangered species, and their ecological functions and values.

Soils: The physical, chemical, and biological properties of the soil on the site, including texture, structure, organic matter, pH, fertility, and contamination.

Human health effects: The potential impacts of the site conditions and features on the health and well-being of the occupants and the surrounding community, such as noise, air quality, water quality, and exposure to hazardous substances.

The basis of energy consumption in determining the percentage of green power or carbon offsets is the quantity of energy used by the project, measured in kilowatt-hours (kWh) or British thermal units (Btu). Green power is electricity generated from renewable sources, such as solar, wind, hydro, biomass, or geothermal. Carbon offsets are reductions or removals of greenhouse gas emissions from a project or activity that compensates for the emissions from another source. According to the LEED Reference Guide for Building Design and Construction1, the Energy and Atmosphere Credit, Green Power and Carbon Offsets, requires the project to engage in a contract for qualified resources that meet the following requirements:

The contract term is at least five years.

The green power or carbon offsets are based on the quantity of energy consumed by the building.

The green power is Green-e Energy certified or the equivalent.

The carbon offsets are Green-e Climate certified, Verified Carbon Standard certified, Gold Standard certified, or the equivalent.

The minimum scope of analysis for a product-specific declaration is cradle-to-gate, which means from raw material extraction to the factory gate. This option requires the use of at least 20 different permanently installed products sourced from at least five different manufacturers that have product-specific declarations.
