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

Occupancy sensors are devices that detect the presence or absence of people in a space and automatically turn the lights on or off accordingly. By installing occupancy sensors for the building’s lighting system, projects can achieve two benefits: improving the indoor environmental quality (IEQ) and reducing the energy consumption. Occupancy sensors can enhance the IEQ by providing lighting control for individual spaces, allowing occupants to adjust the light levels to their preferences and needs. Occupancy sensors can also save energy by avoiding unnecessary lighting when spaces are unoccupied, thus lowering the electricity demand and greenhouse gas emissions. References: LEED v4 Reference Guide for Building Design and Construction, p. 507 1; LEED v4 Reference Guide for Building Operations and Maintenance, p. 241 1

Building-level energy metering is a prerequisite in LEED that requires the installation of energy meters to track the total energy usage of a building12. It helps to monitor and optimize the energy performance of the building and to report the data to USGBC3. Green metering, site evaluation data, and energy savings records are not terms used in LEED.

LEED encourages compact communities because they provide reduction in travel associated with reaching services. Compact communities are communities that have high-density development patterns, mixed land uses, walkable streets, and diverse transportation options. Compact communities reduce the need for driving long distances to access various services, such as work, education, health care, recreation, or shopping. This reduces fuel consumption, greenhouse gas emissions, air pollution, traffic congestion, and infrastructure costs. The LEED Green Associate Candidate Handbook states that one of the intents of the Location and Transportation category is to “reduce vehicle miles traveled (VMT)” [1, p. 12]. References: LEED Green Associate Candidate Handbook, [Compact Communities | U.S. Department of Housing and Urban Development]

The feedback mechanism is a process of collecting and analyzing data from the building occupants to evaluate the performance of the building and identify opportunities for improvement1. Occupants are the primary source of feedback, as they are the ones who experience the building on a daily basis and can provide valuable insights on its comfort, functionality, and satisfaction2.
