Which of the following strategies satisfy the Sustainable Sites Credit, Rainwater Management?\
Answer(s): B
This strategy meets the requirement of the Sustainable Sites Credit, Rainwater Management, which aims to reduce runoff volume and improve water quality by replicating the natural hydrology and water balance of the site, based on historical conditions and undeveloped ecosystems in the region. The credit requires projects to retain the runoff from the developed site for at least the 80th percentile of rainfall events, using low-impact development and green infrastructure practices. Minimizing impervious cover reduces the amount of runoff generated and allows more infiltration and evapotranspiration of rainwater.

A building owner upgrades the building automation system (BAS) to allow programmable load control. Which of the following credits can be pursued because of the upgrade?
Answer(s): A
Demand response is a voluntary program that encourages building owners to reduce their electricity use during peak periods or shift it to off-peak times. The upgraded BAS can enable the building owner to participate in demand response programs by allowing programmable load control, which can adjust the operation of HVAC, lighting, and other systems based on the demand response signals. This can help reduce the stress on the grid, lower the electricity costs, and earn LEED points.

Which of the following prerequisites or credits has a minimum occupancy requirement?
Answer(s): D
The Indoor Environmental Quality Prerequisite for Minimum Indoor Air Quality Performance has a minimum occupancy requirement to ensure that indoor air quality (IAQ) assessments accurately reflect the conditions experienced by building occupants. This prerequisite focuses on achieving acceptable IAQ within the building by meeting or exceeding local codes or ASHRAE standards, ensuring the health and well-being of the occupants.
The LEED O+M Reference Guide's Indoor Environmental Quality section details the requirements for maintaining minimum IAQ performance, including the importance of considering occupancy levels in IAQ assessments.
Storage locations are required for which of the following recyclable materials?
This is the correct answer because LEED v4.1 O+M requires projects to provide storage locations for at least five of the following recyclable materials: mixed paper, corrugated cardboard, glass, plastics, metals, batteries, mercury-containing lamps, and electronic waste. Option D lists five of these materials, while the other options include materials that are not required by LEED, such as paint, wood pallets, or electronics.

In the calculations for Water Efficiency Prerequisite, Indoor Water Use Reduction, private use refers to lavatory faucets used by which of the following types of occupants?
This answer is correct because private use refers to lavatory faucets that are not for common use and are intended for the exclusive use of specific occupants. According to the LEED v4 Indoor Water Use Reduction Calculator1, private use applies to the following types of occupants: apartment residents, motel guests, nursing home residents, and dorm residents. The other options are incorrect because they either include common use lavatory faucets (such as prisoners, hospital staff, hotel guests, and fire-station staff) or do not include lavatory faucets at all (such as hospital inpatients and hotel staff).
