A new commercial building is being designed to use small capacity air handling units. To meet the requirements of the Carbon Dioxide Monitoring strategy in the Indoor Environmental Quality Credit, Enhanced Indoor Environmental Quality Strategies, where would CO2 monitors need to be located?
Correct Answer: B
Explanation According to the LEED v4 Reference Guide for Building Design and Construction, the Carbon Dioxide Monitoring strategy requires CO2 monitors to be located in each densely occupied space, which is defined as a space with a design occupant density of 25 people or more per 1,000 square feet (93 square meters). This strategy is intended to provide feedback on ventilation system performance and indoor air quality12 References: 1: LEED v4 Reference Guide for Building Design and Construction, Indoor Environmental Quality Credit: Enhanced Indoor Air Quality Strategies, Option 2: Additional Enhanced IAQ Strategies, Strategy 3: Carbon Dioxide Monitoring, page 704. 2: LEED v4 Reference Guide for Building Design and Construction, Glossary, page 1019.
Question 292
Where must a building's no-smoking signage be posted?
Correct Answer: C
This is the requirement for the Indoor Environmental Quality prerequisite Environmental Tobacco Smoke Control, which applies to all LEED BD+C rating systems. The intent is to prevent or minimize exposure of building occupants, indoor surfaces, and ventilation air distribution systems to environmental tobacco smoke. The no-smoking signage must explicitly state the 25 ft. (8 m) limit and communicate the no-smoking policy to occupants.
Question 293
Which of the following should be analyzed when pursuing an Integrative Design Process focusing on Energy-Related Systems?
Correct Answer: A
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 aspects1: 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 bridging Lighting levels, such as the target illumination levels, daylighting potential, and lighting power density Plug and process loads, such as the equipment and appliances that consume electricity, and their schedules and controls Programmatic and operational parameters, such as the occupancy, operating hours, and zoning of the building Thermal 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 system The 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 goals2. Acoustic performance of the project is related to the indoor environmental quality and occupant comfort goals of the project, not the energy performance goals3. 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 goals4.
Question 294
For schools intended for grades eight and below (or ages 14 and below), which of the following scenarios would demonstrate compliance with Location and Transportation Credit, Access to Quality Transit, Schools, Option 2. Pedestrian Access?
Correct Answer: B
For schools intended for grades eight and below (or ages 14 and below), Option 2. Pedestrian Access requires that at least 50% of the students live no more than a 3/4 mi. (1.20 km) walking distance from a functional entry of a school building. This option aims to encourage schools to locate in areas where students can walk or bike to school, reducing vehicle trips and emissions, and promoting physical activity and health. Option 2 is available only for projects that do not meet the requirements of Option 1. Transit-Served Location, which requires access to quality transit service within a 1/4 mi. (400 m) walking distance for at least 50% of the students.Reference: Access to Quality Transit credit in LEED BD+C: Schools v4 -LEED V51 LEED Certification- Requirements for LT CREDIT: ACCESS TO QUALITY TRANSIT2 Understanding the LEED BD+C: Location and Transport credit3
Question 295
What is the definition of the evapotranspiration rate?
Correct Answer: D
The evapotranspiration rate is the amount of water loss in a vegetated surface in units of water depth, such as millimeters or inches. It is a measure of the water demand of the plants and the climate conditions. It is used to calculate the baseline water use for irrigation in the Outdoor Water Use Reduction credit.
