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

Under the BUG Rating Method, each exterior luminaire must have backlight, uplight, and glare ratings that do not exceed the allowable values established for the project’s applicable Model Lighting Ordinance lighting zone. The lighting zone reflects the surrounding environmental context, from intrinsically dark areas to high-activity commercial locations. Full-cutoff fixtures may help control uplight, but LEED evaluates the complete BUG classification rather than requiring every fixture to carry a particular cutoff designation. A minimum color temperature of 3,500 K is not a BUG compliance requirement and could increase short-wavelength nighttime impacts. Mounting fixtures three mounting heights from the boundary relates to certain boundary-light calculations, not universal BUG compliance. Therefore, acceptable fixture ratings for the designated MLO lighting zone are required.

ASHRAE 62.1-2010 is the standard that an engineer should use when establishing minimum ventilation rates for a new mechanically ventilated space to earn Indoor Environmental Quality, Minimum Indoor Air Quality Performance. This is the standard referenced by theLEED V5BD+C Reference Guide for this prerequisite. Local building code, International Mechanical Code 2012, and the ventilation code requiring the greatest volume of outside air are not acceptable alternatives for this prerequisite.

The expanded requirement is to track and report construction energy and fuel consumption for both the primary contractor and all subcontractors. This provides a more complete inventory of emissions associated with cranes, generators, heaters, temporary lighting, construction equipment, vehicles, site offices, and other jobsite operations. Tracking only the general contractor could omit a substantial share of actual construction emissions. Temporary solar generation may reduce purchased electricity or generator use, but it does not replace the requirement to quantify the relevant consumption and emissions. A building-material life-cycle assessment evaluates embodied impacts associated with product manufacture and the building life cycle rather than operational emissions produced by construction-site activities. Comprehensive contractor and subcontractor reporting therefore creates the data needed to measure, manage, and reduce construction-related carbon emissions.

The Indoor Environmental Quality Credit, Enhanced Indoor Air Quality Strategies aims to establish better quality indoor air for the building occupants that promotes their comfort and well-being1. This credit requires the project team to implement several strategies to reduce the exposure of occupants and HVAC systems to environmental tobacco smoke, airborne contaminants, and chemicals1. One of the strategies is to design and construct all interior partitions to full height (deck-to-deck) or provide a hard-lid ceiling for spaces where hazardous gases or chemicals may be present or used2. This strategy helps prevent the migration of contaminants from one space to another through the plenum3. A copy room is an example of such a space, as it may contain printers, copiers, toners, and solvents that can emit volatile organic compounds (VOCs) and particulate matter (PM) into the air4. Therefore, the project team can achieve Indoor Environmental Quality Credit, Enhanced Indoor Air Quality Strategies by providing a hard-lid ceiling for the copy room.
