• Question 122:

  A building manager changes the sequence of operation for boilers to better match heating demand as a result of an ASHRAE Level 2 analysis. Which of the following is an example of an appropriate topic for training of building operations staff to continue implementation of this change and meet the requirements of Energy and Atmosphere Credit, Existing Building Commissioning - Implementation?

  A. Sensor calibration
  B. Test and balance procedures
  C. Cooling tower water management
  D. Operating schedules and requirements
  D. Operating schedules and requirements

  ---

  Training building operations staff on operating schedules and requirements is appropriate when implementing changes in the sequence of operation for boilers. This ensures that the staff can effectively manage the new operating sequence to match heating demand, as identified by the ASHRAE Level 2 analysis.

  References: The LEED v4.1 O+M reference guide suggests that training should focus on areas directly affected by implemented changes.Since the sequence of operation for boilers has been modified, staff training should cover the new operating schedules and requirements to ensure continued implementation of the change.

  After implementing changes in the sequence of operation for boilers based on an ASHRAE Level 2 analysis, an appropriate topic for training building operations staff is operating schedules and requirements. This training ensures that staff understand and can effectively implement the new operating procedures, maintaining the improved efficiency and performance of the boilers.

• Question 123:

  The WaterSense label or local equivalent requirement in Water Efficiency Prerequisite, Indoor Water Use Reduction ensures that eligible newly installed plumbing fixtures will

  A. be advertised as LEED compliant
  B. be both water efficient and high performing
  C. comply with mandatory federal government regulations
  D. comply with all international plumbing system requirements
  B. be both water efficient and high performing

  ---

  The WaterSense label, or a local equivalent, is required for all newly installed fittings and fixtures that are eligible for the label, as per the LEED v4 update. This label ensures that the fixtures used in a LEED building meet both water efficiency and high performance testing standards. The WaterSense label is backed by independent, third-party certification and products bearing this label are verified to perform as well or better than their less efficient counterparts. They are also certified to use at least 20 percent less water.

• Question 124:

  Which action supports compliance with Indoor Environmental Quality Prerequisite, Minimum Indoor Air Quality Performance?

  A. Installing CO2 sensors in all spaces
  B. Meeting ASHRAE ventilation requirements
  C. Conducting occupant comfort surveys
  D. Using low-emitting materials
  B. Meeting ASHRAE ventilation requirements

  ---

  Minimum Indoor Air Quality Performance requires compliance with ASHRAE ventilation standards or local codes to ensure adequate outdoor air delivery for occupant health.

• Question 125:

  Which refrigerant was phased out due to the Montreal Protocol?

  A. CFC-11
  B. HCFC-22
  C. HFC-134a
  D. HCFC-123
  A. CFC-11

  ---

  CFC-11 was phased out due to the Montreal Protocol because it is a chlorofluorocarbon (CFC) that contributes to ozone depletion. The protocol aimed to phase out substances with high ozone-depleting potential (ODP).

  References: The Montreal Protocol on Substances that Deplete the Ozone Layer is a global agreement that regulates the production and consumption of nearly 100 man-made chemicals referred to as ozone-depleting substances (ODS), including CFCs.

• Question 126:

  What is the minimum percentage reduction from the baseline required to earn the exemplary performance point for the Indoor Water Use Reduction Credit, Option 2?

  A. 20%
  B. 25%
  C. 30%
  D. 35%
  C. 30%

  ---

  To earn the exemplary performance point for the Indoor Water Use Reduction Credit, Option 2, a project must achieve a minimum of 30% water use reduction from the baseline.

  References: This requirement is detailed in the LEED v4 O+M reference materials, which specify the thresholds for achieving points under the Indoor Water Use Reduction Credit.

• Question 127:

  Discussing the project goals to help identify the credits and options that the team should attempt is an example of

  A. documenting LEED credits
  B. creating the Basis of Design (BOD)
  C. developing the LEED Scorecard
  D. implementing the Commissioning (Cx) Plan
  C. developing the LEED Scorecard

  ---

  Developing the LEED Scorecard is the process of selecting the credits and options that align with the project goals and are feasible for the project team to achieve. The LEED Scorecard is a tool that helps track the progress and performance of the project against the LEED rating system requirements. Discussing the project goals is an important step in developing the LEED Scorecard, as it helps the team prioritize the credits and options that bring the most value to the project owner, environment, and community.

• Question 128:

  To determine possible credit compliance for Energy and Atmosphere Credit, Advanced Energy Metering, what information needs to be verified?

  A. That the meter data is remotely accessible
  B. That the meter is capable of storing data for at least 12 months
  C. That the meter(s) can be manually read
  D. That the meter(s) record data at a minimum of 15 minute intervals
  D. That the meter(s) record data at a minimum of 15 minute intervals

  ---

  The correct answer is D because the meter(s) must record data at a minimum of 15 minute intervals to comply with Energy and Atmosphere Credit, Advanced Energy Metering, as stated in the LEED v4.1 O+M Reference Guide1.This requirement ensures that the meter data is granular enough to capture the variations in energy consumption and demand, and to enable the identification of energy saving opportunities. The other options are incorrect because they are either not required or relevant for this credit.

• Question 129:

  A LEED AP is reviewing construction documents to identify the regularly occupied spaces on a project to ensure that floor area values are utilized consistently across credits. What aspects of each space should the LEED AP consider?

  A. Rate of outdoor air provided per person
  B. Fire ratings of installed wall and ceiling assemblies
  C. Maximum number of intended occupants standing or seated
  D. Typical duration of intended occupancy in each space per day
  C. Maximum number of intended occupants standing or seated

  ---

  When identifying regularly occupied spaces in a project, the LEED AP should consider the maximum number of intended occupants, whether standing or seated, in each space. This is important for ensuring consistency in floor area values across various credits, such as those related to indoor environmental quality or space utilization. The consideration of occupants helps in determining space functionality and occupancy patterns, which are critical for accurate LEED assessments.References:LEED AP Operations + Maintenance Reference Guide, Indoor Environmental Quality section.

• Question 130:

  Which of the following is the most appropriate use of untreated stormwater?

  A. Irrigation
  B. Boiler water makeup
  C. Drinking fountain
  D. Cooling water makeup
  A. Irrigation

  ---

  Untreated stormwater, due to its potential contaminants, is not suitable for potable uses but can be effectively utilized for non-potable applications such as irrigation. It provides a viable alternative to using treated water for landscape irrigation, thereby conserving potable water resources. This use aligns with sustainable water management practices encouraged by LEED, which promote the reduction of potable water usage for landscape irrigation.

  References:

  The LEED Reference Guide for Green Building Design and Construction and the LEED O+M Reference Guide both encourage the use of untreated stormwater for irrigation as part of an integrated water management approach. This conservation strategy is covered under the Water Efficiency category and is a common topic in LEED AP O+M training sessions.
