  A. 50
  B. 70
  C. 76
  D. 85
  A. 50

  ---

  This answer is correct because it matches the requirement of the Energy and Atmosphere Credit, Optimize Energy Performance, which aims to reduce the environmental and economic impacts associated with excessive energy use. The credit requires projects todemonstrate an improvement in energy performance compared to a baseline building, using one of the three options available.For buildings eligible to receive an energy performance rating using the Environmental Protection Agency's ENERGY STAR?Portfolio Manager tool, the option is to achieve a rating of at least 50, which corresponds to the median energy performance of similar buildings nationwide1. The other options are incorrect because they are either higher than the minimum rating or not applicable to this option.

  Buildings account for what percentage of total energy use?

  A. 30%
  B. 40%
  C. 50%
  D. 60%
  B. 40%

  ---

  Buildings account for 40% of total energy use in the U.S., according to the U.S.Environmental Protection Agency1.This is consistent with the global estimate by the International Energy Agency, which states that buildings and construction sector accounted for 36% of final energy use in 20182.

  References: LEED AP O+M Exam Guide, page 305;LEED v4.1 O+M Reference Guide, page 97.

  Buildings are one of the primary consumers of energy worldwide, and they account for a significant percentage of total energy use. The correct percentage is 40%, which encompasses energy used for heating, cooling, lighting, and operating buildings. This figure reflects the extensive impact that building design, construction, and operations have on energy consumption and the potential for energy savings in this sector.

  The figure that buildings account for 40% of total energy use is a commonly cited statistic in the field of sustainability and is mentioned in LEED training materials and documentation. It is a crucial factor that drives the Energy and Atmosphere (EA) category within the LEED rating systems, pushing for strategies that reduce energy consumption and improve building energy performance.

• Question 73:

  At a minimum, which two factors must be continuously monitored by the system in order to achieveIndoor Environmental Quality Credit, Thermal Comfort?

  A. Air speed and humidity
  B. Humidity and air temperature
  C. Air speed and air temperature
  D. Radiant temperature and air speed
  B. Humidity and air temperature

  ---

  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 credit.

  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.

• Question 74:

  The project team is attempting to achieve Option 1. Lighting Controls in Indoor EnvironmentalQuality Credit, Interior Lighting. Which of the following is required documentation?

  A. Table of lighting controls installed
  B. Manufacturers' data for occupancy sensors
  C. The total area of the building square footage
  D. A photometric chart of the multi-occupant space
  A. Table of lighting controls installed

  ---

  The correct answer is A because a table of lighting controls installed is the required documentation for Option 1.Lighting Controls in Indoor Environmental Quality Credit, Interior Lighting, as stated in the LEED v4.1 O+M Reference Guide1.The table must include the type and location of each lighting control device, the controlled lighting power, and the percentage of lighting power controlled by each device1. The other options are incorrect because they are either not required or relevant for this option.

• Question 75:

  Which of the following standards is applicable in order to comply with Indoor Environmental Quality Credit, Thermal Comfort?

  A. SCAQMD Rule #1168
  B. ASHRAE 55-2010
  C. ASHRAE 52.2-2007
  D. SCAQMD Rule #1113
  B. ASHRAE 55-2010

  ---

  ASHRAE 55-2010 is the standard applicable for compliance with the Indoor Environmental Quality Credit, Thermal Comfort. This standard outlines the conditions for acceptable thermal environments and is used for the design, evaluation, and operation of buildings to meet thermal comfort requirements.

  References: The LEED v4.1 O+M reference guide specifies that ASHRAE 55-2010 is the standard for thermal comfort, focusing on ensuring quality thermal environments conducive to occupants' comfort and well-being1.

• Question 76:

  Rainwater harvesting can be used for which of the following credits or prerequisites?

  A. Water Efficiency Credit, Water Metering
  B. Water Efficiency Credit, Indoor Water Use Reduction
  C. Water Efficiency Prerequisite, Indoor Water Use Reduction
  D. Water Efficiency Prerequisite, Building-Level Water Metering
  B. Water Efficiency Credit, Indoor Water Use Reduction

  ---

  Rainwater harvesting is a strategy that can be used to reduce indoor water use, which is a part of the Water Efficiency Credit under the LEED AP Operations + Maintenance (LEED AP O+M) V4.1. By collecting and using rainwater for non-potable uses such as toilet flushing or irrigation, buildings can significantly reduce their demand for municipally treated water. This aligns with the goals of the Indoor Water Use Reduction credit, which encourages the reduction of potable water usage inside the building.
