LEED-AP-BD+C Exam Dumps - LEED AP Building Design + Construction (LEED AP BD+C)

This is because:

A building automation system (BAS) is a system that controls and monitors various aspects of a building’s operation, such as lighting, heating, ventilation, air conditioning, security, fire alarm, and energy management1.

A BAS can allow programmable load control (PLC), which is the ability to adjust the power consumption of devices or equipment based on a schedule, a sensor, or an event2. PLC can help reduce the energy demand and cost of a building by optimizing the use of resources and avoiding unnecessary or wasteful consumption3.

The LEED AP BD+C V4 credit for Demand Response requires that buildings have a demand response program that can respond to changes in electricity prices or supply by reducing or shifting the demand for electricity4. A BAS can enable such a program by allowing PLC and other features that can modulate the power usage of devices or equipment in response to market signals or internal conditions.

Therefore, installing a BAS to allow PLC can help achieve the Energy and Atmosphere Credit for Demand Response by reducing the energy demand and cost of a building.

Food gardens may be included or excluded from the calculations for Water Efficiency Credit, Outdoor Water Use Reduction, as per the project team’s discretion. If included, food gardens must be calculated using 100% potable water. If excluded, food gardens must be irrigated with 100% captured rainwater, recycled graywater, or water treated and conveyed by a public agency specifically for nonpotable uses. References:

LEED v4 BD+C WE Guide2

This method is recommended when the project occupancy is not known, because it provides the default occupant density values for various space types, such as offices, classrooms, retail, and restaurants1. These values are based on the typical or average occupancy of similar spaces, and can be used to estimate the ventilation requirements and energy performance of the project2.

Detailed Explanation:

T60 is the unit used to measure reverberation time, which is the time it takes for sound to decay by 60 decibels in a space. This metric is critical for achieving the Acoustic Performance credit under LEED, as it ensures that spaces are designed to provide optimal acoustic environments that enhance occupant comfort and productivity.

Xeriscaping is a landscaping method that reduces water demand by using plants that are adapted to dry climates, mulching the soil to retain moisture, and minimizing the amount of lawn and other turf areas. Xeriscaping can help save water, money, and energy, as well as improve the health of the soil and the environment.

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:

Every location in the U.S. identifies four regional credits that are of particular importance for that region. These credits are selected by the USGBC regional councils and chapters based on the environmental, social, and public health issues that are relevant for their areas. A project can earn up to four bonus points by achieving these regional credits.

Providing a vehicular access drive that is less than 16 ft. (5 m) in width is considered an acceptable minor improvement within the wetland buffer for Location and Transportation Credit, Sensitive Land Protection. This credit requires avoiding development on land that meets one or more of the following criteria: prime farmland, floodplains, threatened or endangered species habitat, water bodies, wetlands, or land within 100 feet (30 meters) of these water bodies or wetlands1. However, the credit allows minor improvements within the wetland buffer if they are necessary for the project and have minimal environmental impact2. Examples of minor improvements include trails, boardwalks, stormwater outfalls, and utility crossings2. References:
