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

Materials and Resources Credit, Construction and Demolition Waste Management

Salvaged materials are materials that have been recovered or diverted from the waste stream for reuse. They can contribute to the achievement of the Construction and Demolition Waste Management credit, which aims to reduce the amount of waste generated by construction and demolition activities and divert it from landfills and incinerators. By reusing salvaged materials, projects can reduce the demand for new materials, conserve natural resources, save energy, and lower greenhouse gas emissions. Salvaged materials can be counted as part of the total waste diverted from disposal, as long as they are not counted for the Building Life-Cycle Impact Reduction credit1.

For schools intended for grades eight and below (or ages 14 and below), Option 2. Pedestrian Access requires that at least 50% of the students live no more than a 3/4 mi. (1.20 km) walking distance from a functional entry of a school building. This option aims to encourage schools to locate in areas where students can walk or bike to school, reducing vehicle trips and emissions, and promoting physical activity and health. Option 2 is available only for projects that do not meet the requirements of Option 1. Transit-Served Location, which requires access to quality transit service within a 1/4 mi. (400 m) walking distance for at least 50% of the students. References:

According to the LEED v4 Reference Guide for Building Design and Construction, Option 2 of the Sourcing of Raw Materials credit requires using products that meet at least one of the responsible extraction criteria for at least 25%, by cost, of the total value of permanently installed building products in the project1. Therefore, for a project with a material cost of $100,000, the minimum material value needed to achieve this option is 25% of $100,000, which is $25,000.

Makeup water meters, conductivity controllers and overflow alarms

According to the Water Efficiency Prerequisite for Indoor Water Use Reduction, cooling towers and evaporative condensers must be equipped with makeup water meters, conductivity controllers and overflow alarms to reduce water consumption and prevent water waste. These devices help monitor and control the water quality, flow rate and level of the cooling system, and alert the operators of any malfunctions or leaks.

References: As per the LEED AP Building Design + Construction (LEED AP BD+C) V4 resources, the installation of makeup water meters, conductivity controllers and overflow alarms is a requirement for cooling towers and evaporative condensers under the Water Efficiency Prerequisite for Indoor Water Use Reduction. This prerequisite aims to reduce indoor water consumption by setting baseline and efficiency standards for fixtures, fittings, appliances, equipment and processes. For cooling towers and evaporative condensers, the prerequisite also requires efficient drift eliminators that reduce drift to a maximum of 0.002% of recirculated water volume for counterflow towers and 0.005% of recirculated water flow for cross-flow towers. For more detailed information, you can refer to the web-based reference guide in the credit library at USGBC’s official website.

Using a non-native or non-adapted plant species on both the vegetated roof and ground level will impact the Sustainable Sites credit Site Development-Protect or Restore Habitat the most. This credit requires that at least 20% of the site area (excluding building footprint) or 5% of the site area (including building footprint) must be vegetated with native or adapted plants. Non-native or non-adapted plants do not qualify for this credit and may also have negative impacts on the local ecosystem and biodiversity. The other credits are not directly affected by the choice of plant species, although they may have other requirements related to vegetation, such as shading, reflectance, or lighting.References: LEED v4 BD+C Reference Guide, Sustainable Sites Category, SSc Site Development-Protect or Restore Habitat, page 648.
