Adaptive reuse focuses on repurposing existing materials or elements to reduce construction waste and resource use. Reusing wood floors as wall panels exemplifies this principle, aligning with LEED credits under Materials and Resources​​.

Implementing a stormwater pollution prevention plan during construction can help projects meet on-site sustainability goals. This plan outlines measures to control runoff and prevent soil erosion, which can carry pollutants into nearby water bodies. By managing stormwater on-site, projects can protect local water quality while also recharging groundwater supplies. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

Chlorofluorocarbons (CFCs) are a type of compound that was widely used in the 20th century in various applications, including as a refrigerant in air conditioning systems such as centrifugal chillers. CFCs are known to deplete the ozone layer when released into the atmosphere, and their use has been phased out in many countries under the Montreal Protocol. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

Gallons per minute or liters per minute refers to the amount of water used by flow fixtures in LEED. Flow fixtures are fixtures that deliver a constant stream of water, such as faucets, showerheads, or hose bibs. The flow rate of these fixtures is measured in gallons per minute (gpm) or liters per minute (L/min), which indicates how much water flows through them in a given time period. The LEED Green Associate Candidate Handbook states that one of the strategies for achieving water efficiency is to “use low-flow faucets and showerheads (maximum 2.5 gpm at 80 psi)” [1, p. 14]. References: LEED Green Associate Candidate Handbook, [Water Efficiency | U.S. Department of Energy]

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

From the Project Surroundings guide:

“Only about 3% of Earth’s water is freshwater.”

This limited availability emphasizes the importance of water conservation in LEED.

To maintain the LEED Green Associate credential, you must earn 30 continuing education hours every two years, with at least six of those hours being LEED specific. This requirement ensures that LEED Green Associates stay up-to-date with the latest developments in green building practices and LEED rating systems. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

 LEED for Neighborhood Development (LEED ND) is a rating system that aims toinspire and help create better, more sustainable, well-connected neighborhoods1. It looks beyond the scale of buildings to consider entire communities1. One of the main goals ofLEED ND is to reduce vehicle miles traveled (VMT) and greenhouse gas emissions by promoting the location and design of neighborhoods that are accessible by foot or public transportation234. Therefore, LEED ND encourages development within and near existing communities or public transportation infrastructure, which is option C.

Composting toilets operate without water, making them ideal for reducing potable water consumption. LEED promotes such innovative technologies for achieving water efficiency credits​​.

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:

As per the LEED prerequisite for Environmental Tobacco Smoke (ETS) Control:

“Prohibit smoking in the building and on property within 25 feet from operable windows, entries and air intakes.”

Building entrances are particularly sensitive areas where smoke can enter the ventilation system.

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.

Submetering systems are devices that measure the water consumption of specific building components, such as cooling towers, irrigation systems, process water systems, or tenant spaces. They allow the facility operator to monitor and optimize the water use of different systems and identify any leaks or inefficiencies12. Submetering systems are also required for some LEED credits, such as Water Metering and Cooling Tower Water Use3.

According to systems thinking, climate change is an example of a positive feedback loop, which means that an initial change in one part of the system causes a chain ofevents that amplify the effects of the change. For example, as the Earth warms due to increased greenhouse gas emissions, ice sheets and glaciers melt, reducing the albedo (reflectivity) of the Earth’s surface and allowing more solar radiation to be absorbed, which further increases the temperature and accelerates the melting process. This is one of several positive feedback loops that can accelerate climate change and make it harder to reverse.

The result of proper design and operation of buildings and neighborhoods is an increase in energy efficiency. Energy efficiency is the ratio of useful output to energy input for a system or process. Energy efficiency can be improved by using less energy to perform the same function or by using renewable or low-impact energy sources. Energy efficiency can reduce greenhouse gas emissions, energy costs, and dependence on fossil fuels1 . References: LEED v4 Green Associate Candidate Handbook1, EPA’s Energy Efficiency

ASHRAE 90.1-2010, Appendix G is the referenced standard for defining the baseline building performance for energy simulation modeling in LEED v4 for Building Design and Construction. The baseline building is a hypothetical building that represents the minimum energy performance required by ASHRAE 90.1-2010, which is a standard for energy efficiency in buildings. The baseline building is used as a benchmark to compare the proposed design of the project and to calculate the percentage of energy cost savings achieved by the project. The baseline building performance is evaluated by following the procedures and assumptions specified in Appendix G of ASHRAE 90.1-2010, such as building envelope, lighting, HVAC systems, service water heating, and renewable energy.

The other options are not relevant to the question, as they are standards for different aspects of green building, such as thermal comfort (ASHRAE 55-2010), air filtration (ASHRAE 52.2-2007), and ventilation (ASHRAE 62.1-2010).
