The LEED AP O+M Reference Guide states that “If a meter fails during the performanceperiod, the project team must extend the performance period to obtain the required three months of data.” Therefore, the best advice is to extend the performance period to gain the full three months of weekly water meter readings.

For the Indoor Environmental Quality Credit, Thermal Comfort, the system must continuously monitor both humidity and air temperature. These two factors are crucial for maintaining thermal comfort within the building environment.

References: The LEED v4.1 O+M reference materials specify the importance of monitoring humidity and air temperature as part of the requirements for achieving the Thermal Comfort credit12.

To achieve the Indoor Environmental Quality Credit, Thermal Comfort, the system must continuously monitor at least two key factors: humidity and air temperature. These factors are critical for maintaining thermal comfort within a building, as they directly affect the perceived comfort levels of the occupants. Proper monitoring and management of humidity and air temperature ensure that the indoor environment remains within comfortable ranges for occupants, contributing to their well-being and productivity.

References:This requirement is specified in the LEED AP Operations + Maintenance reference guide within the section on Indoor Environmental Quality Credit, Thermal Comfort. The guide emphasizes the importance of maintaining optimal levels of humidity and air temperature for achieving thermal comfort in indoor spaces.

The correct answer is B because the transportation surveys must be distributed across all tenants proportionately, according to their populations, as stated in the LEED v4.1 O+M Reference Guide1. This ensures that the survey results are representative of the actual transportation patterns of the building occupants and avoids sampling bias. The other options are incorrect because they either do not account for the population size of each tenant or are not relevant for the survey distribution.

An ASHRAE Level 2 audit focuses on a detailed analysis of the building's energy systems and their operation against predefined sequences of operation to identify energy conservation opportunities. It includes a thorough review of building energy use and a site survey to identify potential energy-saving measures. Commissioning of an existing building, on the other hand, is a more comprehensive process that involves verifying and documenting that all of the building's systems perform interactively according to the owner's current operational needs and the building's design intent. It often includes system testing, calibration, and adjustments to ensure optimal performance.References:The distinction between an ASHRAE Level 2 audit and commissioning is detailed in the Energy and Atmosphere section of the LEED O+M Reference Guide, emphasizing the different objectives and scope of these activities.
