What document allows a LEED AP to register a project and sign the Certification Agreement?
Answer(s): A
According to the LEED v4: Building Design + Construction Guide, the document that allows a LEED AP to register a project and sign the Certification Agreement is the Owner Confirmation of Agent Authority. This form is used to validate the Certification Agreement when it is signed by someone other than the owner, such as a LEED AP. It provides proof that the owner accepts the conditions in the Certification Agreement and authorizes the LEED AP to act as the owner's agent for the purpose of LEED project certification. The other choices are not relevant documents for this purpose.

Which of the following is the location of CO2 sensors in naturally ventilated spaces to comply with the Indoor Environmental Quality Prerequisite, Minimum Indoor Air Quality Performance?
Answer(s): C
According to the LEED v4: Building Design + Construction Guide, the location of CO2 sensors in naturally ventilated spaces to comply with the Indoor Environmental Quality Prerequisite, Minimum Indoor Air Quality Performance is between 3 ft. and 6 ft. (1 m and 2 m) above the floor. This is one of the requirements for Option 2. Naturally Ventilated Spaces, which applies to projects that rely on natural ventilation for all or part of the occupied spaces. The CO2 sensors must be located in each zone with natural ventilation openings, and must be capable of generating an alarm when the CO2 concentration exceeds the design value.The other choices are not correct, because:At least 6 ft. (2 m) above the floor is the location of CO2 sensors in mechanically ventilated spaces, not naturally ventilated spaces.At least 3 ft. (1 m) away from windows is a general guideline for locating CO2 sensors, but it does not specify the height above the floor.On the ceiling 3 ft. (1 m) away from adjacent walls is not a recommended location for CO2 sensors, as it may not reflect the actual CO2 concentration at the breathing zone of the occupants.

Which of the following should be analyzed when pursuing an Integrative Design Process focusing on Energy-Related Systems?
The correct answer is A, site conditions. According to the LEED v4: Building Design + Construction Guide, the Integrative Process Prerequisite, Integrative Project Planning and Design, requires the project team to perform a preliminary "simple box" energy modeling and analysis before the completion of schematic design. The purpose of this analysis is to evaluate the energy performance goals of the project and to identify and compare the energy-related design strategies. The analysis should include the following aspects:Site conditions, such as climate, solar orientation, shading, and natural ventilation potential Massing and orientation, such as building shape, size, and orientation, and how they affect the heating and cooling loads, daylight availability, and passive design strategies Basic envelope attributes, such as insulation levels, window-to-wall ratio, glazing properties, infiltration rates, and thermal bridgingLighting levels, such as the target illumination levels, daylighting potential, and lighting power densityPlug and process loads, such as the equipment and appliances that consume electricity, and their schedules and controlsProgrammatic and operational parameters, such as the occupancy, operating hours, and zoning of the buildingThermal comfort ranges, such as the acceptable temperature and humidity levels for the occupants HVAC system selection, such as the type, efficiency, and control of the heating, ventilation, and air conditioning systemThe other choices are not aspects that should be analyzed when pursuing an integrative design process focusing on energy-related systems, because:Potable water availability is related to the water efficiency and water quality goals of the project, not the energy performance goals.Acoustic performance of the project is related to the indoor environmental quality and occupant comfort goals of the project, not the energy performance goals. Applicability of green vehicles to the project is related to the location and transportation and greenhouse gas emissions goals of the project, not the energy performance goals.

The design team and project owner decided not to pursue Energy and Atmosphere Credit, Enhanced Commissioning, but would hire a Commissioning Authority (CxA) to oversee the requirements for Energy and Atmosphere Prerequisite, Fundamental Commissioning and Verification. What is a required responsibility for the CxA to achieve the stated objective?
Answer(s): D
According to the LEED v4: Building Design + Construction Guide, the Energy and Atmosphere Prerequisite, Fundamental Commissioning and Verification, requires the project to hire a Commissioning Authority (CxA) to oversee the commissioning process for the mechanical, electrical, plumbing, and renewable energy systems and assemblies. The CxA must have documented commissioning authority experience in at least two building projects, and must not be an employee of the design or construction firms, although they may be contracted through them. The CxA must report the results, findings, and recommendations directly to the owner. One of the required responsibilities for the CxA to achieve the prerequisite is to verify installation and performance of the commissioned systems. This includes conducting site observations and spot- checking of equipment installation, performing functional performance testing of the systems, verifying system performance by reviewing testing and balancing reports, and preparing a summary commissioning report of the activities and results.The other choices are not required responsibilities for the CxA to achieve the prerequisite, but they are additional responsibilities for the CxA to achieve the Energy and Atmosphere Credit, Enhanced Commissioning, which goes beyond the prerequisite by including more systems, more verification activities, and more documentation. These additional responsibilities are:Verify that training requirements are completed. This includes reviewing training plans, agendas, and materials, and verifying that the training delivery and documentation are completed and consistent with the owner's project requirements (OPR).Develop systems manual for the commissioned systems. This includes compiling and reviewing the systems manual that provides the necessary information for operating and maintaining the commissioned systems.Review contractor submittals for the commissioned systems. This includes reviewing the design intent and basis of design documentation, and providing feedback on the contractor submittals related to the commissioned systems, such as shop drawings, product data, and samples.

What strategy does the U.S. Green Building Council (USGBC) use to adapt LEED for international projects?
USGBC's vision for using LEED internationally is to promote green building practices that are globally applicable, locally relevant, and culturally sensitive. To achieve this vision, USGBC provides opportunities for alternative compliance paths (ACPs) that meet the unique needs of a particular region, such as climate, codes, standards, market conditions, and priorities. ACPs are modifications or additions to existing LEED credits or prerequisites that recognize regional differences and allow for more flexibility and applicability of LEED3. ACPs are developed by USGBC in collaboration with local green building councils, experts, and stakeholders, and are reviewed and approved by the LEED Steering Committee. ACPs are available for various regions and countries, such as China, India, Brazil, Europe, and Canada.
