Plug-in task lighting will be utilized in a LEED project at all workstations. The task lighting is not included in the installed lighting power calculations for Energy and Atmosphere Prerequisite, Minimum Energy Performance since
Correct Answer: C
Explanation Plug-in task lighting is considered as furniture and is not included in the installed lighting power calculations for Energy and Atmosphere Prerequisite, Minimum Energy Performance. It is also not required to comply with the lighting control requirements of ASHRAE 90.1-2010. However, it can be used to satisfy the individual control requirement of Indoor Environmental Quality Credit, Interior Lighting, Option 1.

Question 147
When using the Integrative Process, what is the best way for the LEED AP to assess the impact of indoor and outdoor water consumption in a Building Design and Construction project?
Correct Answer: A
When using the Integrative Process, the best way for the LEED AP to assess the impact of indoor and outdoor water consumption in a Building Design and Construction project is to perform a preliminary water budget analysis before the completion of schematic design. This analysis should include the following steps1: * Identify the project's water sources and uses, such as potable water, reclaimed water, rainwater, graywater, blackwater, irrigation, cooling towers, etc. * Estimate the baseline water consumption for each use based on the applicable codes, standards, and benchmarks. * Identify potential water conservation strategies that can reduce the demand or increase the supply of water, such as low-flow fixtures, native landscaping, rainwater harvesting, graywater reuse, etc. * Evaluate the feasibility, cost-effectiveness, and environmental benefits of each strategy using a life- cycle approach. * Select the most appropriate strategies and document how they inform the design decisions and meet the project goals. * Compare the projected water consumption with the baseline and calculate the percentage reduction. Performing a preliminary water budget analysis before the completion of schematic design allows the LEED AP to identify opportunities for water efficiency and innovation early in the design process. It also helps to optimize the integration of water systems with other building and site systems, such as energy, materials, indoor environmental quality, etc. Moreover, it supports the achievement of other LEED credits related to water efficiency, such as WE Prerequisite 1: Outdoor Water Use Reduction, WE Prerequisite 2: Indoor Water Use Reduction, WE Credit 1: Outdoor Water Use Reduction, WE Credit 2: Indoor Water Use Reduction, WE Credit 3: Cooling Tower Water Use2.

Question 148
Which of the following Water Efficiency credits differ between LEED Building Design and Construction: New Construction and LEED Building Design and Construction: Healthcare?
Correct Answer: C
. LEED Building Design and Construction: Healthcare has additional appliance and process water requirements in Water Efficiency Prerequisite, Indoor Water Use Reduction LEED Building Design and Construction: New Construction and LEED Building Design and Construction: Healthcare have the same Water Efficiency credits, except for the Cooling Tower Water Use credit, which is only applicable to the former. However, the Indoor Water Use Reduction prerequisite differs between the two rating systems, as the Healthcare version requires additional calculations for appliance and process water use, such as medical equipment, laundry, and kitchen equipment.

Question 149
When calculating the reverberation time of a room, which of the following pieces of information is least relevant?
Correct Answer: D
When calculating the reverberation time of a room, the operating sound level of the nearest HVAC equipment is the least relevant piece of information. The reverberation time is the time it takes for the sound to decay by 60 decibels after the source stops emitting sound. The reverberation time depends on the volume and the surface area of the room, as well as the sound absorption coefficients of the materials that cover the surfaces. The height and width of the room are needed to calculate the volume and the surface area. The noise reduction coefficient of the ceiling surface and the sound absorption coefficient of the floor surface are needed to calculate the total sound absorption of the room. The operating sound level of the nearest HVAC equipment is not relevant for calculating the reverberation time, but it may affect the background noise level and the speech intelligibility in the room.

Question 150
Which of the following are all considered regular building occupants?
Correct Answer: B
Regular building occupants are individuals who consistently use the building. According to LEED, this includes: * Staff (employees working full-time or part-time) * Primary and secondary students (school occupants) * Higher education students (university students who regularly attend) * Residents (permanent occupants of a residential building) Retail customers, visitors, and periodic volunteers are considered transient occupants and are not classified as regular occupants.
