  In rooms that are densely populated, CO2 monitors must be located a minimum of 4 feet (1.2 meters) above the floor. This placement ensures that the monitors can accurately measure the concentration of CO2 in the breathing zone of the occupants, providing reliable data that can be used to assess and control indoor air quality. Proper placement of CO2 monitors is critical for effective ventilation and for maintaining a healthy indoor environment, especially in areas with high occupancy where CO2 levels

  can rise quickly and impact comfort and well-being.

• Question 86:

  When a building owner is deciding whether to execute an ASHRAE Level 2 audit or commissioning for Energy and Atmosphere Credit, Existing Building Commissioning -Analysis, which of the following statements most appropriately explains the difference between an ASHRAE Level 2 audit and commissioning of an existing building?

  A. An ASHRAE Level 2 audit is required for newer buildings while commissioning is required for buildings in operation for more than five years
  B. An ASHRAE Level 2 audit requires development of an energy use breakdown based on sub-metering while commissioning requires development of an energy use breakdown based on energy modeling
  C. An ASHRAE Level 2 audit involves testing the operation of the systems against the sequences of operation while commissioning involves determining that the system operation meets the owner's current facility requirements
  D. An ASHRAE Level 2 audit focuses on finding major upgrades to the building envelope or me-chanical, electrical, or controls systems while commissioning focuses on controls, proper sys-tem operations, and efficiency improvements
  C. An ASHRAE Level 2 audit involves testing the operation of the systems against the sequences of operation while commissioning involves determining that the system operation meets the owner's current facility requirements

  ---

  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.

• Question 87:

  A 1,500 ft2 (139 m2) mobile home is built in the downtown area of a major city. 90% of the project's gross floor will be completed by the time of occupancy. LEED certification is being sought. Which rating system would be the most appropriate one to use?

  A. LEED Interior Design and Construction
  B. LEED Building Design and Construction
  C. LEED for Homes
  D. No rating system
  C. LEED for Homes

  ---

  For a mobile home, especially one built in a major city, the most appropriate LEED rating system to use would be LEED for Homes. This is because ASHRAE 90.1 and associated LEED rating systems typically exclude low-rise residential buildings, which include single-family houses, multifamily structures of three stories or fewer above grade, and manufactured houses (modular or mobile homes). Since the mobile home in question falls under the category of manufactured houses, it would be more fitting to pursue LEED for Homes certification, which is designed to cater to residential projects.References:Information derived from the ASHRAE 90.1-2013 User's Manual indicates the exclusion of low-rise residential buildings, including manufactured houses, from the standard's scope .

The inclusion of parking under the solar canopy contributes to the Heat Island Reduction credit by providing shade and reducing surface temperatures.

  References:

  The site plan provided indicates two distinct sustainability measures: rainwater management and vegetated roof implementation. Rainwater management pertains to strategies that manage and mitigate the impacts of rainfall runoff. It contributes to the Sustainable Sites Credit for Rainwater Management by reducing runoff volume and improving water quality, which is in line with LEED requirements for managing precipitation on-site. Additionally, the presence of a vegetated roof, as shown in the plan, is a

  strategy for mitigating heat islands. This contributes to the Sustainable Sites Credit for Heat Island Reduction, which aims to minimize the impact on microclimates and human and wildlife habitats by reducing heat-absorbing surfaces.

  References:

  The LEED BD+C Reference Guide, specifically the Sustainable Sites (SS) category, outlines the importance of rainwater management and heat island reduction strategies. These are fundamental aspects covered in the LEED AP O+M training materials, which emphasize site sustainability as a critical component of the overall sustainability of a building project.
