- B. Provide a large opening to dilute air contaminates
- C. Create positive pressure in the room
- D. Provide a hard-lid ceiling
Answer: D
Explanation:
Explanation
The Indoor Environmental Quality Credit, Enhanced Indoor Air Quality Strategies aims to establish better quality indoor air for the building occupants that promotes their comfort and well-being1. This credit requires the project team to implement several strategies to reduce the exposure of occupants and HVAC systems to environmental tobacco smoke, airborne contaminants, and chemicals1. One of the strategies is to design and construct all interior partitions to full height (deck-to-deck) or provide a hard-lid ceiling for spaces where hazardous gases or chemicals may be present or used2. This strategy helps prevent the migration of contaminants from one space to another through the plenum3. A copy room is an example of such a space, as it may contain printers, copiers, toners, and solvents that can emit volatile organic compounds (VOCs) and particulate matter (PM) into the air4. Therefore, the project team can achieve Indoor Environmental Quality Credit, Enhanced Indoor Air Quality Strategies by providing a hard-lid ceiling for the copy room.

remediate sites already in decline
When a project team sustainably develops a project site, the design should aim to remediate sites already in decline, such as brownfields, degraded lands, or abandoned properties. By doing so, the project can restore the environmental quality, ecological functions, and social value of the site, as well as reduce the pressure on undeveloped lands and natural habitats. LEED offers credits for projects that choose to locate on and remediate sites already in decline, such as the Sustainable Sites Credit, Site Assessment and the Sustainable Sites Credit, Brownfields Remediation1.
NEW QUESTION # 42
The maximum number of points for Water Efficiency Credit, Cooling Tower Water Use can be obtained by
- A. utilizing a once-through system without recirculation
- B. conducting a one-time potable water analysis to determine acceptable non-potable sources
- C. limiting cooling tower make-up to 50% of a potable source
- D. achieving a minimum of 10 cooling tower cycles by increasing the level of make-up water treatment
Answer: D
Explanation:
Explanation
Achieving a minimum of 10 cooling tower cycles by increasing the level of make-up water treatment is the way to obtain the maximum number of points for Water Efficiency Credit, Cooling Tower Water Use. This credit aims to conserve water used for cooling tower equipment by encouraging the use of non-potable water sources and increasing the cycles of concentration1. The cycles of concentration are the ratio of the concentration of dissolved solids in the blowdown water to the concentration of dissolved solids in the make-up water2. Increasing the cycles of concentration reduces the amount of make-up water and blowdown water, and thus saves water and energy2. The credit has two options: Option 1. Non-potable Water Source (1 point) and Option 2. Cooling Tower Water Use (2 points). Option 1 requires using at least 50% non-potable water for cooling tower make-up water1. Option 2 requires achieving a minimum number of cooling tower cycles based on the quality of the make-up water, as specified in Table 1 of the credit requirements1. The maximum number of cycles is 10, which can be achieved by increasing the level of make-up water treatment to meet the criteria for conductivity, silica, and alkalinity1. Therefore, Option 2 is the way to obtain the maximum number of points for this credit. References:

NEW QUESTION # 43
Which of the following could be considered diverted construction waste?
- A. Land-clearing debris
- B. Excavated soil
- C. Asphalt with aggregate
- D. Alternative daily cover
Answer: C
Explanation:
Explanation
According to the LEED v4 Reference Guide for Building Design and Construction, diverted construction waste is defined as "materials that are diverted from disposal in landfills or incineration facilities and are instead reused, recycled, composted, or salvaged"1. Asphalt with aggregate is an example of a material that can be recycled and reused for paving or other applications. Excavated soil and land-clearing debris are excluded from the calculation of the total construction and demolition waste for the MR Credit Building Life-Cycle Impact Reduction1. Alternative daily cover is a material that is used to cover the surface of an active landfill at the end of each day to control odors, pests, and litter. It is not considered as diversion because it does not reduce the amount of waste sent to landfills2. References: MR Credit Building Life-Cycle Impact Reduction, LEED v4 Reference Guide for Building Design and Construction3142

This applies to both the main entrance and the service entrances, regardless of their location or frequency of use.
The signage is intended to communicate the no-smoking policy to occupants and visitors and prevent environmental tobacco smoke from entering the building. References: EQ Prerequisite Environmental Tobacco Smoke Control, LEED v4 Reference Guide for Building Design and Construction123
NEW QUESTION # 46
Which of the following should be analyzed when pursuing an Integrative Design Process focusing on Energy-Related Systems?
- A. Site conditions
- B. Potable water availability
- C. Applicability of Green Vehicles to the project
- D. Acoustic performance of the project
Answer: A
Explanation:
Explanation
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.
