What is the definition of the evapotranspiration rate?
Correct Answer: D
The evapotranspiration rate is the amount of water loss in a vegetated surface in units of water depth, such as millimeters or inches. It is a measure of the water demand of the plants and the climate conditions. It is used to calculate the baseline water use for irrigation in the Outdoor Water Use Reduction credit.

Question 142
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 143
Which of the following could be considered diverted construction waste?
Correct Answer: D
According to the LEED v4 Reference Guide for Building Design and Construction, diverted construction waste is defined as "materials that are diverted from disposal in landfills or incineration facilities and are instead reused, recycled, composted, or salvaged"1. Asphalt with aggregate is an example of a material that can be recycled and reused for paving or other applications. Excavated soil and land-clearing debris are excluded from the calculation of the total construction and demolition waste for the MR Credit Building Life- Cycle Impact Reduction1. Alternative daily cover is a material that is used to cover the surface of an active landfill at the end of each day to control odors, pests, and litter. It is not considered as diversion because it does not reduce the amount of waste sent to landfills2.

Question 144
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?
Correct Answer: A
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 Reference: 1: LEED v4 Reference Guide for Building Design and Construction, Indoor Environmental Quality Credit: Low-Emitting Materials, page 692. 2: LEED v4 Reference Guide for Building Design and Construction, Indoor Environmental Quality Credit: Interior Lighting, page 715.
Question 145
In pursuit of the Materials and Resources Credit, Building Disclosure and Optimization - Sourcing of Raw Materials, Option 2. Leadership Extraction Practices, which of the following statements is true related to products purchased for temporary use (formwork, bracing and scaffolding) on the project?
Correct Answer: A
Temporary wood products cannot be included in the calculations for the Materials and Resources Credit, Building Disclosure and Optimization - Sourcing of Raw Materials, Option 2. Leadership Extraction Practices. This is because the credit only applies to permanently installed building products, not to products purchased for temporary use on the project1. The other options are false. If any temporary wood materials are included in the calculation, they must be excluded from the total value of permanently installed building products1. Non-certified wood materials do not contribute to other credits, unless they meet other criteria such as recycled content or regional materials2. FSC-certified wood materials purchased for more than one project cannot be applied to other projects seeking LEED certification, unless they are reused or salvaged materials3.
