Pass the USGBC Leadership in Energy and Environmental Design (LEED) LEED-Green-Associate Questions and answers with CertsForce

The LEED for Neighborhood Development rating system has four certification levels: Certified, Silver, Gold, and Platinum. Each level requires a minimum number of points to achieve, based on the total number of available points in the rating system. The total number of available points is 110, and the minimum points for Platinum certification is 801. Therefore, the maximum points a new construction platinum LEED for Neighborhood Development certification level can earn are 110 - 80 = 30 points. However, there are also four regional priority credits that can be earned for addressing geographicallyspecific environmental issues2. These credits are worth one point each, and can be added to the total score of a project. Therefore, the maximum possible points a new construction platinum LEED for Neighborhood Development certification level can earn are 30 + 4 = 34 points. However, the question asks for the maximum points that can be earned by a new construction project. According to the LEED Reference Guide for ND, new construction projects must meet all prerequisites and achieve at least 50% of the points available under the Green Infrastructure and Buildings category3. This category has 21 criteria, each worth one point, except forCertified Green Buildings, which is worth up to five points4. Therefore, the maximum points available under this category are 21 + 4 = 25 points. Since new construction projects must achieve at least 50% of these points, they must earn at least 13 points under this category. This means that they have less points to earn under the other categories (Smart Location and Linkage, and Neighborhood Pattern and Design), which have a total of 32 criteria worth one point each4. Therefore, the maximum points a new construction project can earn under these categories are 110 - 25 - 13 = 72 points. Adding the regional priority credits, the maximum possible points a new construction project can earn are 72 + 4 = 76 points. To achieve Platinum certification, a new construction project must earn at least 80 points1. Therefore, the maximum points a new construction platinum LEED for Neighborhood Development certification level can earn are 80 - 76 = 4 points under each of the four categories: Smart Location and Linkage, Neighborhood Pattern and Design, Green Infrastructure and Buildings, and Regional Priority Credits. Hence, the answer is D. 16.

According to the LeadingGreen Study Guide:

"The first step in the certification process is the Project Registration. Projects can be registered on the GBCI website (www.gbci.org)... Before registration, the process begins with selecting the appropriate rating system using the 40/60 rule... "

Thus, selecting the correctrating systemis the initial key step before registration and documentation submission. The selection ensures alignment with the project type and its characteristics.

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)

Resource depletion is a major environmental concern related to energy use. The extraction and use of non-renewable energy resources (such as fossil fuels) can lead to their depletion over time. This is why strategies that reduce energy use or utilize renewable energy sources are important in green building practices. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

The minimum program requirements (MPRs) are the basic characteristics that a project must possess in order to be eligible for LEED certification. One of theMPRs for the LEED for New Construction and Major Renovations Rating System is to comply with the minimum project size, which is defined as having a gross floor area of at least 1,000 square feet (93 square meters) that is capable of achieving a minimum level of energy efficiency13. References: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide3

receptacle load is the electrical load that is connected to the building’s electrical system through receptacles (also known as outlets or sockets). Receptacle load includes both regulated and non-regulated loads, such as computers, printers, monitors, lamps, refrigerators, microwaves, coffee makers, etc. Receptacle load does not include hard-wiredequipment, such as lighting fixtures, HVAC systems, or elevators12.

Receptacle load is one of the major components of plug and process loads (PPLs), which consume about 47% of primary energy in U.S. commercial buildings2. Reducing receptacle load can help improve building energy efficiency and achieve LEED certification. One of the strategies to reduce receptacle load is to use automatic receptacle controls, which are devices that turn off or reduce power to receptacles when they are not in use. Automatic receptacle controls are required by ANSI/ASHRAE/IES Standard 90.1-2019: Energy Standard for Buildings Except Low-Rise Residential Buildings, as well as NIH DRM 10.5.313.

The methodology that is used to evaluate and study the economic performance of a building or system over its entire life is life cycle assessment (LCA). LCA is a technique that assesses the environmental aspects and potential impacts associated with a product, process, or service throughout its life cycle, from raw material extraction to end-of-life disposal or recycling7. LCA can also include an economic dimension by incorporating life cycle costing (LCC), whichestimates the total costs of ownership over the life cycle of a product or system8. By combining LCA and LCC, one can evaluate the environmental and economic performance of a building or system in a holistic way, taking into account both the initial investment costs and the long-term operational costs. This can help identify trade-offs and synergies between environmental and economic objectives, as well as opportunities for improving efficiency and reducing impacts9. References: Life-cycle assessment7; What is Life Cycle Assessment (LCA)?8; Life Cycle Costing in Construction Projects: A Case Study of a Municipal Building in Portugal9

Water Efficiency is the only credit category that does not have a prerequisite in LEED v4 for Building Design and Construction. Prerequisites are the minimum requirements that all projects must meet to be eligible for LEED certification. They are mandatory and non-weighted, meaning they do not contribute to the project’s score. The other credit categories have at least one prerequisite each, as shown in the table below:

In addition to temperature and air movement, humidity is another factor to consider when implementing thermal comfort strategies. Humidity is the amount of water vapor in the air, which affects how warm or cool people feel. High humidity can make people feel hotter and more uncomfortable, while low humidity can cause dryness and irritation of the skin, eyes, nose, and throat. Thermal comfort strategies should aim to maintain an optimal level of humidity that balances human comfort and health with energy efficiency and moisture control. The other options are not factors to consider when implementing thermal comfort strategies. Methane off-gassing is the release of methane gas from organic matter decomposition or anaerobic digestion, which contributes to greenhouse gas emissions and climate change. Carbon dioxide concentrations are a measure of indoor air quality that indicates the level of ventilation and fresh air supply in a space. Combustion processes from vehicles are sources of outdoor air pollution that emit carbon monoxide, nitrogen oxides, particulate matter, and other harmful substances. References: LEED Green Associate Candidate Handbook, page 29; USGBC, [Indoor Environmental Quality], page 2.

One of the causes of surface water degradation is the expansion of impervious surfaces. Impervious surfaces are those that do not allow water to infiltrate into the soil, such as roads, parking lots, rooftops, and sidewalks. Impervious surfaces increase the amount and speed of stormwater runoff, which can carry pollutants, sediments, nutrients, and pathogens into surface water bodies such as streams, rivers, lakes, and oceans. Impervious surfaces also reduce groundwater recharge, lower base flow in streams, increase flooding and erosion, alter streammorphology and habitat, and affect water temperature and dissolved oxygen levels2. Therefore, impervious surfaces can have significant negative impacts on the quality and quantity of surface water resources. References: Surface Water as a cause of land degradation from dryland salinity3; What is Water Pollution?4
