USGBC Updated LEED-AP-BD+C Exam Questions and Answers by laurence

Temporary air filters should be installed when HVAC equipment or ductwork is operated during construction. Construction activities generate dust, fibres, aerosols, and other contaminants that can enter air-handling equipment, accumulate inside ducts, foul coils, or later be distributed through occupied spaces. Temporary filtration helps prevent this contamination and should be accompanied by sealing unused duct openings, protecting equipment, maintaining clean work areas, and replacing filters before occupancy. Low-emitting materials reduce chemical emissions from installed products, but they do not protect HVAC components from construction dust and debris. Extreme-heat protection addresses worker or occupant safety under high-temperature conditions rather than construction-related air-system contamination. Proper HVAC protection supports healthier indoor air and aligns with LEED v5’s quality-of-life emphasis on occupant health and well-being.

The Construction General Permit (CGP) for the Sustainable Sites Prerequisite, Construction Activity Pollution Prevention, must contain an installation plan for perimeter control. This is part of the Erosion and Sedimentation Control (ESC) Plan, which is designed to prevent loss of soil during construction by stormwater runoff and/or wind erosion, prevent sedimentation of storm sewer or receiving streams, and prevent polluting the air with dust and particulate matter 1 .

Conducting a site analysis is a method to assess the regional context of a building’s design for sustainability. A site analysis involves collecting and evaluating information about the site’s location, climate, ecology, history, culture, infrastructure, regulations, and stakeholders. This can help identify the opportunities and constraints for the project, as well as the potential impacts and benefits for the environment and the community. A site analysis can inform the design decisions regarding site selection, site development, water management, energy efficiency, material selection, indoor environmental quality, and innovation 1 2 .

According to the LEED V5 Reference Guide for Building Design and Construction, the discovery phase of energy-related systems should identify ventilation rates, along with other factors such as building orientation, envelope attributes, lighting levels, plug and process loads, and programmatic and operational parameters 1 . These factors should be used to create a preliminary “simple box” energy model to evaluate the energy performance of the building and explore potential strategies to reduce energy use 1 . The other options are not relevant for the discovery phase of energy-related systems. Functional performance tests are part of the implementation phase 1 . Thermal comfort ranges are related to indoor environmental quality 2 . Transportation options are related to sustainable sites 3 .
