Free Practice Questions for USGBC LEED-Green-Associate Exam

A list of materials to be diverted from disposal is a component of a construction waste management plan. A construction waste management plan is a document that outlines the goals, procedures, and responsibilities for diverting construction and demolition waste from landfills or incinerators. A list of materials to be diverted from disposal identifies the types and quantities of materials that can be recycled, reused, salvaged, or donated, as well as the destinations and methods for diversion. The other options are not components of a construction waste management plan. Projected cost savings from diverting waste is a potential benefit of implementing a construction waste management plan, but it is not a required component. Quantity of waste generated from excavated soil is a factor that affects the construction waste generation rate, but it is not a component of a construction waste management plan. Distance of the recycling facility from the project site is a factor that affects the transportation emissions and costs associated with diverting waste, but it is not a component of a construction waste management plan. References: LEED Green Associate Candidate Handbook, page 28; USGBC, [Materials and Resources], page 3.

A building automation system is the correct answer because it helps monitor, control, and optimize building systems such as HVAC, lighting, ventilation, and scheduling. In LEED Energy and Atmosphere, ongoing energy performance depends not only on efficient design but also on proper operation. A building automation system can identify abnormal energy spikes, adjust systems based on occupancy, support demand response, and help facility managers maintain efficient performance. Low-performance insulation increases heating and cooling loads, making it incorrect. Kitchen appliances may be efficient or inefficient depending on the product, so the option is too general. Oversized equipment without proper controls often wastes energy and can reduce comfort. Automation supports energy conservation, operational efficiency, and performance verification after occupancy.

A waste reduction, reuse and recycling program must collect and measure the waste diverted through recycling and reuse, which is the amount of waste that is prevented from going to landfills or incinerators by being recovered, reused, or recycled. This is one of the key indicators of the environmental performance and benefits of a waste management program, as it can reduce greenhouse gas emissions, conserve natural resources, save energy and water, and create jobs. LEED v4.1 recognizes and rewards this strategy in the Construction and Demolition WasteManagement credit1, which aims to reduce construction and demolition waste disposed of in landfills and incineration facilities2. The other options are not directly related to the waste reduction, reuse and recycling program, as they involve different types of materials or metrics that are not relevant for measuring waste diversion. References: LEED Link: Construction and Demolition Waste Management, section “LEED v4.1 BD+C: Construction and Demolition Waste Management”; LEED v4 Waste Management Credits - Zero Waste, section “LEED v4 Waste Management Credits”

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.

LEED assigns rating systems based on project type and scope, using market-sector-specific adaptations where appropriate. This is the best answer because LEED is not one single checklist for every building. Different rating systems and adaptations address new construction, interiors, existing buildings, homes, schools, healthcare, retail, data centers, warehouses, hospitality, and neighborhoods. Residential and institutional projects may have different needs, occupancy patterns, code issues, and performance concerns, so LEED provides rating system pathways that fit the project context. Option A is misleading because credit weightings are part of LEED point allocation, but they do not alone determine rating system applicability. Option B is too narrow. Option D is incorrect because LEED O+M applies to existing building operations and maintenance, not all residential or institutional projects.

A brownfield site is appropriate for development of LEED projects because it is a site that has been previously used for industrial or commercial purposes and may be contaminated by pollutants or hazardous substances. Developing a brownfield site can help reduce environmental impacts, such as soil erosion, habitat loss, and water consumption, by reusingexisting infrastructure and restoring degraded land. LEED projects can earn credits for developing on brownfield sites under the Sustainable Sites category. References: LEED v4 BD+C Reference Guide, Sustainable Sites, page 35; Best Management Practice #14: Alternative Water Sources1

Energy use intensity (EUI) is a measure of energy use per unit of floor space. It is calculated by dividing the total energy consumed by the building in one year (measured in kilowatt-hours or kilo- British Thermal Units) by the total gross floor area of the building (measured in square feet or square meters). EUI is a useful metric for comparing the energy performance of different buildings or benchmarking against national averages. EUI can vary depending on building type, climate, occupancy, and other factors. Generally, a lower EUI indicates better energy efficiency and lower environmental impact. References: What is Energy Use Intensity (EUI)?2; Energy Use Intensity (EUI)3

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