USGBC LEED-Green-Associate Actual Questions

The project team should have selected LEED for Existing Buildings: Operations and Maintenance Rating System, as the operational and maintenance phase has begun for a newly constructed school in operation for one year and undergoing minor improvements. The LEED rating systems are designed to address the specific needs and characteristics of different types of buildings and projects. The project team should choose the most appropriate rating system for their project based on the scope, scale, and goals of the project. The LEED for Existing Buildings: Operations and Maintenance Rating System is intended for buildings that are already in use and want to improve their performance and sustainability through best practices in operation, maintenance, renovation, and occupant engagement1 . References: LEED v4 Green Associate Candidate Handbook1, LEED v4 O+M Reference Guide

receptacle load is the electrical load that is connected to the building’s electrical system through receptacles (also known as outlets or sockets). Receptacle load includes both regulated and non-regulated loads, such as computers, printers, monitors, lamps, refrigerators, microwaves, coffee makers, etc. Receptacle load does not include hard-wired equipment, such as lighting fixtures, HVAC systems, or elevators12.

Receptacle load is one of the major components of plug and process loads (PPLs), which consume about 47% of primary energy in U.S. commercial buildings2. Reducing receptacle load can help improve building energy efficiency and achieve LEED certification. One of the strategies to reduce receptacle load is to use automatic receptacle controls, which are devices that turn off or reduce power to receptacles when they are not in use. Automatic receptacle controls are required by ANSI/ASHRAE/IES Standard 90.1-2019: Energy Standard for Buildings Except Low-Rise Residential Buildings, as well as NIH DRM 10.5.313.

Rainwater storage cisterns are components of a collected rainwater irrigation system that are most likely to make it cost prohibitive over a conventional system in a large site that has a short, intense rainy season and a long, dry season. A collected rainwater irrigation system is a system that collects, stores, and distributes rainwater for irrigation purposes. Rainwater storage cisterns are containers that store the collected rainwater until it is needed for irrigation. In a large site that has a short, intense rainy season and a long, dry season, the rainwater storage cisterns would need to be very large and durable to capture and store enough rainwater for the dry season. This would increase the initial cost and maintenance cost of the system compared to a conventional system that uses potable water or groundwater for irrigation1 . References: LEED v4 Green Associate Candidate Handbook1, EPA’s Rainwater Harvesting

Including subsidies for carpools is a strategy that can increase the number of points the project receives for Location and Transportation credits. This is because it reduces the demand for single-occupancy vehicle trips and parking spaces, which in turn reduces greenhouse gas emissions, traffic congestion, and land consumption12. The project can earn up to 15 points for the Transportation Demand Management credit by providing various incentives and programs to encourage alternative modes of transportation, such as carpooling, public transit, biking, or walking12.
