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

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​​.

SRI is a measure of a material's ability to reflect solar heat (reflectivity) and release absorbed heat (emissivity). This index helps evaluate materials for reducing the heat island effect under the Sustainable Sites category​​.

Life-cycle costing (LCC) is a method of estimating the total cost of owning and operating an asset over its entire life span. LCC considers all costs associated with the acquisition, installation, operation, maintenance, and disposal of the asset12. LCC can help businesses make better decisions about purchasing, budgeting, pricing, and investing in assets2.

LCC does not quantify environmental impacts such as acidification, eutrophication, or global warming. These impacts are measured by life-cycle assessment (LCA), which is a method of evaluating the environmental effects of a product or service throughout its life cycle. LCA considers the inputs and outputs of materials, energy, and emissions at each stage of the product or service life cycle34. LCA can help businesses identify opportunities to reduce their environmental footprint, improve their sustainability performance, and comply with environmental regulations4.

However, LCC and LCA are often used together to compare different alternatives based on both economic and environmental criteria. For example, a business may use LCC to estimate the energy costs of different lighting options, and LCA to estimate the greenhouse gas emissions of each option. By combining LCC and LCA results, the business can select the option that minimizes both costs and emissions.

LEED credits in the Sustainable Sites category emphasize minimizing light trespass:

“Good exterior lighting design results in the reduction of three forms of light pollution: uplight, glare, and light trespass.”

Light trespass refers to unwanted light spilling over beyond the site boundary, negatively affecting adjacent properties and ecosystems.

Monitoring outdoor airflow is a strategy for improving indoor environmental quality during construction. Outdoor airflow is the amount of fresh air that enters a building through natural or mechanical means. Monitoring outdoor airflow can help ensure that adequate ventilation is provided to the building during construction, which can prevent the accumulation of indoor pollutants, such as dust, debris, or volatile organic compounds, that may affect the health and comfort of the workers or occupants. The LEED Green Associate Candidate Handbook states that one of the strategies for achieving indoor environmental quality is to “monitor outdoor airflow” [1, p. 16]. References: LEED Green Associate Candidate Handbook, [Outdoor Airflow | ASHRAE]

The LeadingGreen Study Guide defines carbon offsets as:

“Alternatively a project can purchase carbon offsets to reduce scope 2 emissions, as one carbon offset is equal to one carbon dioxide equivalent of greenhouse gases”.

Additionally, LEED recognizes carbon offsets as a method to:

“...compensate for emissions occurring elsewhere.”

Hence, the correct and verified answer isCarbon offsets.

According to the LeadingGreen Guide:

“Individual controls for lighting have a significant effect on occupants’ comfort. Meeting the unique needs of each occupant can be accomplished through effective design of lighting controls…”

LEED credits under EQc6 emphasize providing lighting comfort and energy savings through such controls.

The U.S. Green Building Council (USGBC) administers the LEED rating systems development. The LEED rating systems are frameworks that provide guidance and criteria for designing, constructing, operating, and maintaining green buildings. The USGBC is responsible for developing, maintaining, and updating the LEED rating systems through a consensus-based process that involves various stakeholders, such as technical experts, industry leaders, government representatives, and public comments. The LEED Green Associate Candidate Handbook states that “USGBC is committed to transforming the way our buildings are designed, constructed and operated through LEED” [1, p. 7]. References: LEED Green Associate Candidate Handbook, [LEED Rating Systems | U.S. Green Building Council]
