LEED-Green-Associate Exam Dumps - USGBC Leadership in Energy and Environmental Design (LEED) Questions and Answers

Daylighting falls under the Indoor Environmental Quality category. LEED awards points for strategies that enhance natural light to improve occupant comfort and reduce energy consumption​​.

Biomass is a renewable energy source that can be used to produce electricity from organic plant and waste material. It is considered green power by the U.S. EPA because it provides environmental benefits and reduces greenhouse gas emissions12.

A site with minimal hardscape (such as concrete, asphalt, or other impervious surfaces) that has a large permeable surface (such as soil, grass, or other vegetation) results in reduced rainwater runoff. This is because permeable surfaces allow rainwater to infiltrate into the ground, replenishing the groundwater and reducing the amount of water that flows over the surface and carries pollutants into storm drains and waterways. Reducing rainwater runoff is one of the goals of the LEED v4 Location and Transportation category, which offers credits for using strategies such as green roofs, permeable paving, rain gardens, and vegetated swales

Integrative process is a collaborative approach that involves all project stakeholders in the design and decision-making process from the beginning to the end of a project. It aims to optimize the performance, environmental, social, and economic outcomes of a project by considering the interrelationships and synergies between various building and site systems. One of the key aspects of integrative process is to establish feedback loops that allow for continuous monitoring, evaluation, and improvement of the project performance during its operation. Therefore, option C is an example of integrative process, while the other options are not directly related to it. References: Integrative process | U.S. Green Building Council, section “Integrative Process”; Understanding Integrative Design in LEED v4, page 1; LEED Integrative Process Credit Explained, section “INTEGRATIVE PROCESS V4 CREDIT OVERVIEW”

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.

ASHRAE 62.1 is a standard that ensures adequate ventilation is supplied to building occupants. ASHRAE stands for the American Society of Heating, Refrigerating and Air-ConditioningEngineers, a professional organization that develops standards and guidelines for the design, operation, and maintenance of buildings. ASHRAE 62.1 is a standard that specifies the minimum ventilation rates and other measures for new and existing buildings that are intended to provide acceptable indoor air quality (IAQ) for the occupants. Ventilation is the process of supplying outdoor air to or removing indoor air from a building. Adequate ventilation is important for maintaining good IAQ, which can affectthe health, comfort, and productivity of the occupants13. References: LEED v4 Green Associate Candidate Handbook1, ASHRAE’s Standard 62.13

Construction IAQ management and LEED strategies directly improve health:

“Using proper construction management practices… protects worker and occupant health by controlling pollutant sources and pathways…”

High VOC materials and low ventilation have adverse effects, not benefits.

An infill site within an existing neighborhood with substantial transit connectivity would maximize LEED points under Location and Transportation. An infill site is a site that has been previously developed or graded and is surrounded by existing development. An existing neighborhood is a geographic area with a variety of land uses, such as residential, commercial, educational, or recreational. Substantial transit connectivity means that the site has access to multiple modes of public transportation, such as buses, trains, light rail, or bicycles. The LEED Green Associate Candidate Handbook states that one of the intents of the Location and Transportation category is to “encourage development within existing communities and public transit infrastructure” [1, p. 12]. References: [LEED Green Associate Candidate Handbook], [Location and Transportation | U.S. Green Building Council]

ASHRAE 189.1 is a standard for the design of high-performance green buildings that covers various aspects of sustainability, energy efficiency, water efficiency, indoor environmental quality, and more. It is an alternate compliance path for the IGCC, which is a model code that contains minimum requirements for green building design and construction. In jurisdictions that adopt the IGCC, a builder has the option to design and construct a building in accordance with the provisions of ASHRAE 189.1 rather than those of the IGCC123.

A site map is required to show the locations of community resources within the specified radius to meet Location and Transportation credits. It visually demonstrates compliance with LEED requirements for access to diverse uses​​.
