QUESTION: 65

A new commercial building is being designed to use small capacity air handling units. To meet the requirements of the Carbon Dioxide Monitoring strategy in the Indoor Environmental Quality Credit, Enhanced Indoor Environmental
Quality Strategies, where would CO2 monitors need to be located?

In each occupied space
In each densely occupied space
In each occupied space and outdoors
In each occupied space over 500 ft2 (46 m2)

Answer(s): B

Explanation:

According to the LEED v4 Reference Guide for Building Design and Construction, the Carbon Dioxide Monitoring strategy requires CO2 monitors to be located in each densely occupied space, which is defined as a space with a design occupant density of 25 people or more per 1,000 square feet (93 square meters). This strategy is intended to provide feedback on ventilation system performance and indoor air quality12

QUESTION: 66

A luxury hotel project is in the design phase and is located on a scenic waterfront. It is one point away from attaining LEED Platinum certification. The LEED AP is recommending that the team pursue Innovation Credit, Innovation, Option 3. Additional Strategies.
Which of the following credits would be desirable considering the location of the project?

Energy and Atmosphere Credit, Optimize Energy Performance, Exemplary Performance
Indoor Environmental Quality Credit, Quality Views, Exemplary Performance
Indoor Environmental Quality Credit, Acoustic Performance, Exemplary Performance
Energy and Atmosphere Credit, Enhanced Commissioning, Exemplary Performance

Answer(s): B

Explanation:

The LEED Platinum certification requires the project to achieve exemplary performance in at least one credit that allows it, as specified in the LEED Reference Guide. One of the credits that meets this criterion is the Indoor Environmental Quality Credit, which focuses on providing healthy and comfortable indoor environments for occupants. The credit has two options: Quality Views and Enhanced Commissioning. Quality Views requires the project to have windows that provide views of natural scenery or water bodies, which can enhance the well-being and satisfaction of occupants. Enhanced Commissioning requires the project to have a comprehensive commissioning plan that ensures all systems are properly installed, tested, and operated before occupancy. Both options can help reduce energy consumption, improve indoor air quality, and create a positive sensory experience for occupants.

QUESTION: 67

Selecting a high-reflectance interior paint which is compliant with South Coast Air Quality Management District (SCAQMD) Rule 1113 can help contribute towards which two credits?

Indoor Environmental Quality Credit, Low-Emitting Materials and Indoor Environmental Quality Credit, Interior Lighting
Indoor Environmental Quality Credit, Low-Emitting Materials and Sustainable Sites Credit, Site Assessment
Indoor Environmental Quality Credit, Low-Emitting Materials and Indoor Environmental Quality Credit, Minimum Indoor Environmental Quality Performance
Indoor Environmental Quality Credit, Enhanced Indoor Environmental Quality Strategies and Indoor Environmental Quality Prerequisite, Minimum Indoor Environmental Quality Performance

Answer(s): A

Explanation:

Selecting a high-reflectance interior paint that meets the SCAQMD Rule 1113 can help contribute towards two credits: Indoor Environmental Quality Credit, Low-Emitting Materials and Indoor Environmental Quality Credit, Interior Lighting. The first credit requires that interior paints and coatings comply with the VOC content limits specified by the SCAQMD Rule 1113 or equivalent standards to reduce indoor air contaminants that are odorous, irritating, and/or harmful to the comfort and well-being of installers and occupants1 The second credit aims to provide high-quality lighting that supports visual acuity and occupant comfort, and that responds to the needs of the space and its users. One of the strategies to achieve this credit is to use light-colored finishes with a minimum reflectance of 0.7 for ceilings, 0.5 for walls, and 0.2 for floors to increase the effectiveness of daylighting and electric lighting systems2

QUESTION: 68

A Photovoltaic (PV) system was installed on a 35,000 ft2 (3 252 m2) project.
What actions need to take place in order to meet compliance for Energy and Atmosphere Prerequisite, Fundamental Commissioning (Cx) and Verification?

No action is necessary as the PV system is not required to be commissioned
The PV system installer should commission his own installations and share the results with the project owner
The Cx agent for the project must conduct or oversee the Cx of the PV system
The building's mechanical engineer should commission his own installations and share the results with the project owner

Answer(s): C

Explanation:

The correct answer is C, the Cx agent for the project must conduct or oversee the Cx of the PV system. According to the LEED v4 Reference Guide for Building Design and Construction, the Energy and Atmosphere Prerequisite, Fundamental Commissioning and Verification, requires that all energy- related systems, including renewable energy systems such as PV, be commissioned by an independent commissioning agent (CxA) or a qualified member of the project team who reports to the owner. The CxA or the qualified team member must perform or oversee all commissioning activities, including developing a commissioning plan, reviewing design documents and submittals, verifying installation and performance, and preparing a commissioning report12
