USGBC Updated LEED-Green-Associate Exam Questions and Answers by koby

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

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”

According to the U.S. Energy Information Administration, space heating accounted for about 32% of energy use for all U.S. commercial buildings in 2018, followed by ventilation and lighting, each at about 10%1. Space heating is the largest single energy end use in U.S. office buildings as well2.

The Forest Stewardship Council (FSC) is a third-party verification organization that certifies forest products that are sourced from responsibly managed forests that meet environmental, social, and economic standards12. FSC-certified wood products are considered environmentally preferable products under the LEED v4 Materials and Resources category, as they reduce the negative impacts of deforestation, habitat loss, and biodiversity loss34.
