What is the best way to prevent a building's indoor pollutant(s)?
Correct Answer: C
The best way to prevent a building's indoor pollutant(s) is to eliminate or control pollutants at the source. Indoor pollutants are substances or particles that can adversely affect the indoor air quality (IAQ) of a building and the health, comfort, and productivity of the occupants. Indoor pollutants can originate from various sources, such as building materials, furnishings, cleaning products, combustion appliances, outdoor air, or occupant activities. Eliminating or controlling pollutants at the source can prevent them from entering or spreading in the indoor environment, which can reduce the exposure and risk for the occupants. Some examples of source control strategies are: using low-emitting materials, installing local exhaust ventilation, sealing combustion appliances, implementing green cleaning practices, and prohibiting smoking13.

Question 62
LEED for Neighborhood Development encourages
Correct Answer: C
LEED for Neighborhood Development (LEED ND) is a rating system that aims to inspire 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 of LEED 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.

Question 63
Which of the following water types is suitable for drinking?
Correct Answer: D
Explanation Potable water is water that is suitable for drinking. Potable water meets or exceeds the Environmental Protection Agency's (EPA) drinking water quality standards and is free of contaminants that are harmful to human health. The other options are not suitable for drinking. Graywater is wastewater from sinks, showers, and laundry that can be reused for non-potable purposes such as toilet flushing and irrigation. Greenwater is rainwater that is collected and stored for non-potable uses. Stormwater is runoff from precipitation that can carry pollutants and sediments into waterways.

Question 64
Which of the following methods provides maximum water efficiency for a building irrigation system?
Correct Answer: A
A drip irrigation system provides maximum water efficiency for a building irrigation system. A drip irrigation system delivers water directly to the root zone of plants, minimizing evaporation, runoff, and overspray. This reduces water consumption and prevents water pollution from fertilizers and pesticides. The LEED Green Associate Candidate Handbook states that one of the strategies for achieving water efficiency in landscaping is to "use efficient irrigation systems, such as drip irrigation" [1, p. 14].

Question 65
The Solar Reflective Index (SRI) applies to which concept?
Correct Answer: B
Explanation The Solar Reflective Index (SRI) is a measure of how well a material reflects solar radiation and releases absorbed heat. It is used to evaluate the performance of cool roofs, which can reduce the heat island effect by lowering the surface temperature of buildings and urban areas.
