LEED-Green-Associate Exam Dumps - LEED Green Associate Exam (LEED GA)

LEED encourages compact communities because they provide reduction in travel associated with reaching services. Compact communities are communities that have high-density development patterns, mixed land uses, walkable streets, and diverse transportation options. Compact communities reduce the need for driving long distances to access various services, such as work, education, health care, recreation, or shopping. This reduces fuel consumption, greenhouse gas emissions, air pollution, traffic congestion, and infrastructure costs. The LEED Green Associate Candidate Handbook states that one of the intents of the Location and Transportation category is to “reduce vehicle miles traveled (VMT)” [1, p. 12]. References: LEED Green Associate Candidate Handbook, [Compact Communities | U.S. Department of Housing and Urban Development]

One of the requirements for the Sustainable Sites Credit: Rainwater Management is that projects must use Green Infrastructure (GI) and Low Impact Development (LID) techniques within the LEED project boundary. GI and LID are design approaches that mimic natural hydrologic processes to manage stormwater runoff at its source. GI and LID techniques include strategies such as rain gardens, bioswales, permeable pavements, green roofs, rain barrels, cisterns, and vegetated buffers. The other options are not requirements for the Sustainable Sites Credit: Rainwater Management. Maximizing open space within the LEED project boundary is a requirement for the Sustainable Sites Credit: Open Space. Calculating the total rainwater runoff for 75th percentile rainfall events is a requirement for the Sustainable Sites Credit: Site Assessment. Using a combination of both structural and non-structural measures to manage a 90th percentile rainfall event is an option for meeting Option 1 of the Sustainable Sites Credit: Rainwater Management. References: LEED Green Associate Candidate Handbook, page 27; USGBC, [Sustainable Sites], page 4-5.

Daylighting is a strategy that involves designing buildings to maximize the use of natural light and reduce the need for artificial lighting1. Daylighting can improve the indoor environmental quality by enhancing the visual comfort, mood, and productivity of the occupants2. Daylighting can also help attain points toward LEED certification by contributing to the credits in the Energy and Atmosphere and Indoor Environmental Quality categories1. Night lighting, installing indoor plants, and installing inoperable windows are not strategies that directly improve the indoor environmental quality or help attain points toward LEED certification.

Air movement is a factor that affects the thermal comfort of occupants, as it influences the heat exchange between the human body and the surrounding air1. Air movement can be controlled by mechanical systems, such as fans, or natural systems, such as operable windows2. LEED v4 requires that at least 50% of individual occupant spaces have thermal comfort controls that allow occupants to adjust air movement in their local environment3.

A neighborhood that includes a diversity of uses is most appropriate to encourage a walkable street design. A diversity of uses means that different types of activities and functions are located within walking distance of each other, such as residential, commercial, retail, educational, recreational, cultural, and civic uses. A diversity of uses creates a vibrant and lively neighborhood that attracts pedestrians and supports social interaction. A walkable street design also incorporates elements such as sidewalks, crosswalks, street trees, lighting, benches, bike lanes, public transit stops, and reduced vehicle speeds to enhance pedestrian safety and comfort. The other options are not appropriate to encourage a walkable street design. An area with a decreased building-height-to-street-width ratio creates a wide and open street that exposes pedestrians to more sun and wind, reducing their comfort level. A development that uses many culs-de-sac in the street design creates a disconnected and irregular street network that limits pedestrian access and mobility. A project in an area designed with streets to facilitate increased speed limits prioritizes vehicle movement over pedestrian safety and comfort. References: LEED Green Associate Candidate Handbook, page 29; USGBC [Location & Transportation], page 2-3.
