USGBC LEED-AP-BD+C Actual Questions

This credit can be earned if the VOC budget method is applied for VOC content. The VOC budget method allows the use of some products that exceed the VOC content limit, as long as the total VOC content of all products within a category does not exceed the total allowable VOC content for that category1. The adhesive is a product within the wet-applied and aerosol adhesives category, which has a VOC content limit of 70 g/L1. The contractor must calculate the VOC budget for this category and ensure that it does not exceed the limit. The other options are not valid ways to earn this credit. The adhesive must be included in the LEED documentation, as all products used in the project must be accounted for1. The credit requires that 100% of the adhesives used comply with the VOC content limit and emissions requirements, not 75% or 95%1.

The make and model of fixtures is required in determining the baseline for the Water Efficiency Prerequisite, Indoor Water Use Reduction.This information is used to calculate the baseline water consumption of the building, which is then compared to the proposed water use to determine the percentage reduction.References: LEED AP Building Design + Construction (LEED AP BD+C) V4 resources1

QUSTION NO: 147

In order to comply with Indoor Environmental Quality Credit, Enhanced Indoor Air Quality Strategies, Option 2.Additional Enhanced IAQ Strategies

A. all entrances to the building must have entryway systems 10 ft. (3 m) long in the direction of travel

B. CO2 monitors must be fitted in all densely occupied spaces and configured to provide an alert

C. all outdoor air supply systems must have an airflow measurement device that measures at least 90% of the airflow

D. all particle filters in the ventilation system must meet Comité Européen de Normalisation (CEN) standard Class F7 or better

Answer: D

To comply with the Indoor Environmental Quality Credit, Enhanced Indoor Air Quality Strategies, Option 2, all particle filters in the ventilation system must meet the Comité Européen de Normalisation (CEN) standard Class F7 or better.This requirement ensures that the air quality inside the building is maintained at a high standard, contributing to the health and well-being of the occupants.References: LEED AP Building Design + Construction (LEED AP BD+C) V4 resources1

Contractor

The contractor is the project team member who should be integrated early into the design phase to assist with earning the Materials and Resources Prerequisite, Construction and Demolition Waste Management Planning. The contractor is responsible for implementing the waste management plan, which includes estimating the types and quantities of waste materials, identifying the diversion strategies, selecting the waste haulers and recyclers, tracking and documenting the waste diversion performance, and training the subcontractors and workers. The contractor can provide valuable input on how to reduce, reuse, and recycle the construction and demolition waste, as well as identify potential challenges and opportunities for achieving the prerequisite requirements.

The Basis of Design (BOD) is the document that contains the design team’s interpretation of the Owner’s Project Requirements (OPR). The BOD describes the proposed systems and how they will meet the OPR, as well as the assumptions and criteria used forthe design.The BOD is a key document for the Integrative Process credit and the Enhanced Commissioning credit in LEED BD+C12.References: LEED BD+C Reference Guide, Integrative Process, page 301; LEED BD+C Reference Guide, Enhanced Commissioning, page 681
