Gallons per minute or liters per minute refers to the amount of water used by flow fixtures in LEED. Flow fixtures are fixtures that deliver a constant stream of water, such as faucets, showerheads, or hose bibs. The flow rate of these fixtures is measured in gallons per minute (gpm) or liters per minute (L/min), which indicates how much water flows through them in a given time period. The LEED Green Associate Candidate Handbook states that one of the strategies for achieving water efficiency is to “use low-flow faucets and showerheads (maximum 2.5 gpm at 80 psi)” [1, p. 14]. References: LEED Green Associate Candidate Handbook, [Water Efficiency | U.S. Department of Energy]

LEED Building Design and Construction Homes and Multifamily Low-rise is a rating system that applies to single-family homes and multifamily buildings between one and three stories. This rating system covers the design and construction phases of residential projects that areintended for human occupancy12. Projects that have more than three stories are not eligible for this rating system, but may qualify for other LEED rating systems, such as LEED Building Design and Construction Multifamily Mid-rise, which applies to multifamily buildings between four and eight stories

Indoor Environmental Quality is the correct LEED credit category. This category addresses the conditions that occupants experience inside a building, including indoor air quality, thermal comfort, lighting quality, daylight, views, acoustics, low-emitting materials, and control of indoor pollutants. The goal is to support occupant health, comfort, satisfaction, and productivity. Indoor Air Quality is an important part of Indoor Environmental Quality, but it is not the full LEED category name. Indoor Energy Quality and Indoor Efficiency Quality are not LEED credit categories. For the LEED Green Associate exam, it is important to distinguish the official category name from related concepts. EQ is broader than air quality alone because it includes comfort, lighting, acoustics, and overall occupant experience.

Daylighting is a strategy that uses natural light to illuminate the interior spaces of a building, reducing the need for artificial lighting and improving the visual comfort and well-being of the occupants. One of the strategies that can help improve daylighting in an office building is tolocate private offices toward the building core and organize cubicles at the perimeter, so that more people can benefit from the access to windows and views. This can also increase the daylight penetration depth and reduce glare and contrast12. References: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide2
