LEED-Green-Associate Exam Dumps - USGBC Leadership in Energy and Environmental Design (LEED) Questions and Answers

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

The Materials and Resources (MR) category focuses on reducing the environmental, economic, and social impacts of building materials from extraction to disposal12. It encourages the use of materials that have lower embodied energy, less waste, more recycled content, and better life-cycle performance12.

Acoustic Performance is a credit that aims to provide workspaces andclassrooms that promote occupants’ well-being, productivity, and communications through effective acoustic design1. This credit falls under the Indoor Environmental Quality category, which addresses the quality of the indoor environment as it relates to the health andcomfort of building occupants2. The Indoor Environmental Quality category has different credits for different LEED rating systems, such as LEED BD+C, LEED ID+C, LEED O+M, and LEED ND3. Acoustic Performance is one of the credits that is available for some of these rating systems, such as LEED BD+C: Schools, LEED ID+C: Commercial Interiors, and LEED O+M: Existing Buildings4.

LEED Rating Systems Overview

LEED rating system

Water closets, also known as toilets, are fixtures that use water to flush human waste into a sewer or septic system. The unit of measure for water closets is gallons (liters) per flush, which indicates the amount of water used for each flushing cycle. The water efficiency of water closets can vary depending on the design, technology, and regulation of the fixture. The LEED rating system encourages the use of water-efficient fixtures that reduce water consumption and wastewater generation12. References: LEED v4 Green Associate Candidate Handbook1, EPA’s WaterSense Toilets2

The Facility Manager is typically responsible for monitoring ongoing energy performance over the life of a building. They oversee the operation and maintenance of building systems, including HVAC, lighting, and other energy-using equipment, and can implement energy management strategies to optimize performance. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

The purpose of a life-cycle assessment (LCA) in LEED is to evaluate the potential environmental impacts of a building through its life-cycle, from the extraction of raw materials, to the manufacturing, transportation, installation, use, maintenance, and disposal or recycling of building materials and products1. LCA can help project teams to compare different design options and select the ones that minimize the environmental impacts of the building, such as global warming potential, ozone depletion potential, acidification potential, eutrophicationpotential, and smog formation potential12. LCA can also help projects earn points for the LEED v4 Building Design and Construction category under the Building Life-Cycle Impact Reductioncredit, which rewards projects for reducing the life-cycle impacts of their structure and enclosure by at least 10% compared to a baseline

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

Installing a solar photovoltaic system can significantly reduce greenhouse gas emissions from a building. Solar panels generate electricity from sunlight, a renewable resource, instead of burning fossil fuels that release carbon dioxide and other greenhouse gases. While solar panels do require an upfront investment, they can also result in lower energy bills over time. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources
