Which of the following contributes to the value of the commissioning process?
Correct Answer: B
Explanation 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.

Question 22
Innovation credits for exemplary performance can be awarded for
Correct Answer: B
Exemplary performance credits are one of the options to earn innovation points under the LEED v4.1 rating system. They are typically awarded for achieving double the credit requirements or the next incremental percentage threshold of an existing LEED v4.1 prerequisite or credit that allows exemplary performance. For example, to earn an exemplary performance point for the Energy and Atmosphere credit Optimize Energy Performance, the project must demonstrate a percentage improvement in the proposed building performance rating compared to the baseline building performance rating per ASHRAE 90.1-2010 by at least 12 percentage points for new construction, or by at least 16 percentage points for major renovations.

Question 23
The current facilities requirements (CFR) and operations and maintenance plan (OMP) required for Energy and Atmosphere Prerequisite, Fundamental Commissioning and Verification must include
Correct Answer: C
Explanation The current facilities requirements (CFR) and operations and maintenance plan (OMP) are two documents that are required for the Energy and Atmosphere Prerequisite, Fundamental Commissioning and Verification. The CFR is a document that describes the owner's project requirements, such as the design intent, performance goals, and operational needs of the building. The OMP is a document that provides information and guidance on how to operate and maintain the commissioned systems and equipment. According to the LEED v4 Reference Guide for Building Design and Construction, the CFR and OMP must include the minimum outside air requirements, which are the minimum rates of outdoor air ventilation that are needed to provide acceptable indoor air quality and thermal comfort for the occupants1. The issue logs, functional performance tests, and installation verification (construction) checklists are not required to be included in the CFR and OMP, but they are part of the commissioning process and documentation.

Question 24
A school wants to incorporate natural daylighting in classrooms on all sides of the building. What can the project design team explain to the school district about how this strategy will affect the operational energy cost?
Correct Answer: B
Natural daylighting can reduce the electricity use for artificial lighting, which is one of the major components of operational energy cost for buildings. By having the lights off or dimmed when sufficient daylight is available, the project can save energy and money. The other options are not necessarily true or relevant for natural daylighting. Heat gain and passive solar heating depend on the orientation, shading, and insulation of the windows, not just the amount of daylight. Reduction in lighting fixture use may reduce re-lamping, but that is not a significant factor in operational energy cost compared to electricity use.

Question 25
Building Product Disclosure and Optimization is based on market
Correct Answer: C
Building Product Disclosure and Optimization is based on market transparency, which means providing information about the environmental and social impacts of the products and materials used in the building. The LEED v4 Reference Guide for Building Design and Construction states that "the intent of this credit category is to encourage the use of products and materials for which life-cycle information is available and that have environmentally, economically, and socially preferable life-cycle impacts"1. By disclosing the information about the product ingredients, environmental product declarations, sourcing of raw materials, and material ingredients optimization, the project team can make informed decisions and support the development of a more sustainable market.
