USGBC LEED-Green-Associate - LEED Green Associate GAFRE Exam (LEED GA)

The protection and restoration of natural vegetation, wetland areas and bodies of water through building footprint consolidation helps to preserve open space and sensitive areas, which are important for maintaining biodiversity, ecosystem services, and human well-being. Building footprint consolidation refers to the strategy of minimizing the area of land that is occupied by a building and its associated infrastructure, such as roads, parking lots, and utilities. By reducing the building footprint, project teams can avoid or minimize the impacts of development on natural habitats, wetlands, and water bodies, which often provide critical functions such aswater quality improvement, flood control, wildlife habitat, and recreation. LEED v4.1 recognizes and rewards this strategy in the Sensitive Land Protection credit1, which aims to conserve existing natural areas and restore damaged areas to provide habitat and promote biodiversity2. References: LEED Link: Sensitive Land Protection, section “LEED v4.1 BD+C: Sensitive Land Protection”; Sensitive Land Protection | U.S. Green Building Council, section “Intent”

Good site design benefits a project in which of the following ways: makes occupants comfortable by providing green spaces. Green spaces are areas of vegetation that improve the quality of life for building occupants and visitors by providing natural views, fresh air, shade, noise reduction, and recreational opportunities. They also reduce heat island effect, improve stormwater management, and sequester carbon dioxide. The LEED Green Associate Candidate Handbook states that one of the intents of the Sustainable Sites category is to “enhance occupant comfort by providing green spaces” [1, p. 13]. References: [LEED Green Associate Candidate Handbook] , [Green Spaces | U.S. Department of Energy]

Carbon offsets are used to balance emissions by reducing or sequestering equivalent amounts of CO₂ elsewhere. LEED supports using carbon offsets to meet energy and atmosphere goals​​.

Recycling is a strategy that can be used during the building process and after occupation to reduce waste. Recycling involves collecting, sorting, processing, and reusing or selling materials that would otherwise be discarded as waste. Recycling can save natural resources, reduce greenhouse gas emissions, create jobs, and lower disposal costs1 . Recycling can also help to achieveLEED credits in the Materials and Resources category by reducing the amount of construction and demolition waste generated by the project or by diverting waste from landfills or incinerators. References: LEED v4 Green Associate Candidate Handbook1, EPA’s Recycling Basics2, LEED v4 BD+C Reference Guide

According to the LEED Study Guide:

“LEED for Operations and Maintenance (LEED O+M) applies to existing buildings that are fully operational and occupied.”

This system evaluates how a building performs after it is constructed and in use, making it the correct fit for a built project.

According to the LEED credit library, the Energy and Atmosphere category for Building Design and Construction: New Construction and Major Renovation has 6 prerequisites and 11 credits, with a total of 33 possible points. The prerequisites are:

Fundamental Commissioning and Verification (required)

Minimum Energy Performance (required)

Building-Level Energy Metering (required)

Fundamental Refrigerant Management (required)

Construction Activity Pollution Prevention (required)

Advanced Energy Metering (required)

The credits are:

Enhanced Commissioning (2-6 points)

Optimize Energy Performance (1-18 points)

Advanced Energy Metering (1 point)

Demand Response (1-2 points)

Renewable Energy Production (1-3 points)

Enhanced Refrigerant Management (1 point)

Green Power and Carbon Offsets (1-2 points)

According to the LEED v4 Minimum Program Requirements (MPRs), there is no minimum required number of occupants or full-time equivalents (FTEs) for which a building must be designed to be considered eligible to pursue certification1. However, the project must serve at least one FTE, which is based on an 8-hour day2. The other options are not part of the MPRs.

Occupant surveys are tools that can be used to identify indoor environmental issues and prepare a corrective action plan to make necessary changes. Occupant surveys are questionnaires that collect feedback from the building users about their satisfaction, comfort, health, and productivity in relation to the indoor environmental quality (IEQ) factors, such as thermal comfort, indoor air quality, lighting quality, acoustic quality, and occupant control. Occupant surveys can help to identify the sources and causes of IEQ problems, as well as the potential solutions and improvements. Occupant surveys are also required for some LEED credits, such as IEQc7.2 Thermal Comfort, Verification1, which requires a corrective action plan if more than 20% of the occupants are dissatisfied with the thermal conditions in the space2. The other options are not directly related to identifying indoor environmental issues and preparing a corrective action plan, as they involve different types of tools or metrics that are not relevant for measuring occupant satisfaction and comfort.
