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

Recycling is the term for collecting, reprocessing, marketing and using materials that are diverted or recovered from the solid waste stream. Recycling is a process that transforms waste materials into new products that can be used for different purposes. Recycling reduces the amount of waste sent to landfills or incinerators, conserves natural resources, saves energy, and reduces greenhouse gas emissions. The LEED Green Associate Candidate Handbook states that one of the intents of the Materials and Resources category is to “reduce waste through recycling during construction and occupancy” [1, p. 15]. References: LEED Green Associate Candidate Handbook, [Recycling Basics | U.S. Environmental Protection Agency]

The LEED Pilot Credit Library is a collection of new credits that are being tested for potential inclusion in future versions of LEED1. The purpose of the library is to allow projects to experiment with innovative strategies and provide feedback to USGBC on their effectiveness, feasibility, and market readiness2. The library also helps USGBC to respond to evolving environmental issues and stakeholder needs2.

The scope of the LEED impact category component Protect Human Health from Direct Exposure to Negative Health Impacts is building occupants and design and construction crew during the construction phase and use phase of the building cycle, within the project boundary and its immediate surroundings. This component aims to reduce the exposure of people to harmful substances or conditions that may affect their health and well-being. This includes indoor air quality, thermal comfort, lighting quality, noise levels, water quality, and safety hazards. The component covers both the construction phase and the use phase of the building cycle, as both stages can pose potential health risks to people involved or affected by the project. The component also considers both the project boundary and its immediate surroundings, as some health impacts may extend beyond the site itself. References: LEED v4 BD+C Reference Guide, Introduction, page 9

ASHRAE 189.1 is a standard that provides guidance for the design, construction, and operation of high-performance green buildings that comply with building codes and voluntary rating systems. The standard covers topics such as site sustainability, water efficiency, energy efficiency, indoor environmental quality, and the impact of materials and resources12. References: LEED v4 Green Associate Candidate Handbook1, ASHRAE’s Standard 189.12
