A project is designed to remodel an existing warehouse into multi-family housing. The exterior facade of the warehouse will remain, but 40% of the interior will be demolished and replaced for interior new construction. New materials will be used for the new construction. To achieve points in the Materials and Resources Credit, Building Life-Cycle Impact Reduction, which credit path option would apply?
Answer(s): D
This option applies to projects that renovate an existing building that meets the definition of abandoned or blighted, and use new materials for at least 50% of the surface area. The project meets these criteria, as the warehouse is an existing building that is presumably abandoned or blighted, and the new construction will use new materials for 40% of the interior and some of the exterior.

Which of the following variables must be included in the calculations for Indoor Environmental Quality Credit, Quality Views?
According to the LEED v4 Reference Guide for Building Design and Construction, the calculations for Quality Views must include the following variables: window size and configuration, glazing factor, window head height, distance of the window from the floor, permanent interior obstructions, and exterior obstructions. Ceiling heights, building furniture, and movable partitions are not required to be included in the calculations.

Large commercial buildings are most often dominated by
Answer(s): A
Large commercial buildings are most often dominated by internal loads, which are the heat gains or losses from people, equipment, lighting, and other sources inside the building. Internal loads can affect the heating and cooling loads and the energy consumption of the building. Therefore, reducing internal loads can improve the building's energy efficiency and performance.

Building Product Disclosure and Optimization is based on market
Answer(s): 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.

The Solar Reflectance Index (SRI) includes the measure of a material's
Answer(s): B
The Solar Reflectance Index (SRI) is a measure of the roof's ability to reject solar heat, as shown by a small temperature rise. It is defined so that a standard black (reflectance 0.05, emittance 0.90) is 0 and a standard white (reflectance 0.80, emittance 0.90) is 100. SRI is calculated using the roof surface's Solar Reflectance (SR) and Thermal Emittance (TE). SR is the fraction of solar energy that is reflected by the roof, and TE is the relative ability of the roof surface to radiate heat. Therefore, SRI includes the measure of a material's ability to reflect solar radiation, but not its ability to absorb or emit thermal radiation.
