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

To be eligible forLEED certification, a project must:

Be a permanent structure on existing land(floating structures like houseboatsdo not qualify).

Have a defined site boundary(mobile homes do not meet this requirement unless they are permanently installed).

Have a minimum floor area of 250 square feet (23.2 m²)(so a900 ft² office qualifies).

Prefabricated buildings (Option A) may qualify if they are permanently installed.

Houseboats (Option C) and mobile homes (Option D) are not eligible unless permanently located.

The new office building (Option B) meets all LEED requirements and is the correct answer.

A preventive maintenance plan is a document that outlines the procedures and schedules for maintaining the building systems and equipment. It helps to ensure that the systems and equipment are operating efficiently and effectively, and that they meet the design intent and performance goals. A preventive maintenance plan can also help to reduce the risk of failures, breakdowns, and repairs, and extend the service life of the systems and equipment. A preventive maintenance plan is especially important for improving the indoor environmental quality, as it can prevent issues such as poor ventilation, air leaks, moisture problems, mold growth, and indoor air pollution. Therefore, the project team should provide the facility manager with a preventive maintenance plan for the building, along with the necessary training and resources to implement it.

LEED v5 WEp2 addresses both plumbing fixtures and water-consuming equipment or processes. The fixture requirements specifically include toilets, urinals, lavatory faucets, kitchen faucets, and showerheads. The prerequisite also establishes minimum efficiency requirements for applicable process systems, including cooling towers and evaporative condensers. Thus, Option C contains components expressly addressed by WEp2: showers and kitchen faucets are flow fixtures, toilets are flush fixtures, and cooling towers are regulated process-water systems. Janitor sinks are specifically identified elsewhere in LEED guidance as fixtures not addressed by the WEp2 fixture requirements, making Option A unsuitable despite the inclusion of a dishwasher. Swimming-pool water also does not represent the prescribed WEp2 minimum equipment requirement in the manner described by Option B. Therefore, Option C is the supported combination.

The commissioning process is a quality assurance process that ensures that the building systems perform as intended, based on the owner’s project requirements and the design team’s basis of design.The commissioning process can provide value to the project by improving energy efficiency, reducing operation and maintenance costs, enhancing occupant comfort and satisfaction, and reducing risks and liabilities123.References: LEED BD+C Reference Guide, Energy and Atmosphere, page 631; LEED BD+C Reference Guide, Enhanced Commissioning, page 661;LEED Building Commissioning: Why You Should Get Accredited
