LEED-AP-BD+C Dumps with Practice Exam Questions Answers

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.

The intent of the Water Efficiency Prerequisite, Outdoor Water Use Reduction is to reduce outdoor water consumption by either eliminating the need for irrigation or reducing the irrigation demand by at least 30% from the baseline. This prerequisite requires project teams to evaluate the project’s outdoor water budget and irrigation water demand using the EPA WaterSense Water Budget Tool or a local equivalent. This will help project teams to estimate and optimize water use in landscape designs by selecting appropriate plant species and irrigation system efficiency.

To comply with Indoor Environmental Quality Credit, Thermal Comfort, the standard that needs to be followed is ASHRAE 55-2010, Thermal Environmental Conditions for Human Occupancy, with errata or a local equivalent 1 . This standard specifies the combinations of indoor thermal environmental factors and personal factors that will produce thermal environmental conditions acceptable to a majority of the occupants within the space 2 . The standard also provides methods for measuring and evaluating thermal comfort, as well as guidance for design, operation, and maintenance of thermal comfort systems 2 .

Large commercial buildings are most often dominated by internal loads, which are the heat gains or losses from people, equipment, lighting, and other sources inside the building. Internal loads can affect the heating and cooling loads and the energy consumption of the building. Therefore, reducing internal loads can improve the building’s energy efficiency and performance.  References :

The credit that should be pursued when considering the regional context of frequent power supply grid fluctuations (brown-outs) is Energy and Atmosphere Credit, Demand Response. This credit encourages participation in demand response programs that reduce peak electricity demand and help stabilize the grid. It also provides an opportunity to earn regional priority points, which are bonus points for credits that address regional environmental issues. The other credits are not directly related to the regional context of brown-outs.
