- D. Install permanent metering on both the water sources and the waste water leaving the site
Answer: B
Explanation:
Explanation
When using the Integrative Process, the best way for the LEED AP to assess the impact of indoor and outdoor water consumption in a Building Design and Construction project is to perform a preliminary water budget analysis before the completion of schematic design. This analysis should include the following steps1:
Identify the project's water sources and uses, such as potable water, reclaimed water, rainwater, graywater, blackwater, irrigation, cooling towers, etc.
Estimate the baseline water consumption for each use based on the applicable codes, standards, and benchmarks.
Identify potential water conservation strategies that can reduce the demand or increase the supply of water, such as low-flow fixtures, native landscaping, rainwater harvesting, graywater reuse, etc.
Evaluate the feasibility, cost-effectiveness, and environmental benefits of each strategy using a life-cycle approach.
Select the most appropriate strategies and document how they inform the design decisions and meet the project goals.
Compare the projected water consumption with the baseline and calculate the percentage reduction.
Performing a preliminary water budget analysis before the completion of schematic design allows the LEED AP to identify opportunities for water efficiency and innovation early in the design process. It also helps to optimize the integration of water systems with other building and site systems, such as energy, materials, indoor environmental quality, etc. Moreover, it supports the achievement of other LEED credits related to water efficiency, such as WE Prerequisite 1: Outdoor Water Use Reduction, WE Prerequisite 2: Indoor Water Use Reduction, WE Credit 1: Outdoor Water Use Reduction, WE Credit 2: Indoor Water Use Reduction, WE Credit 3: Cooling Tower Water Use2.

NEW QUESTION # 50
The Solar Reflectance Index (SRI) includes the measure of a material's
- A. ability to absorb solar radiation
- B. ability to reflect thermal radiation
- C. ability to reflect solar radiation
- D. color (shade of gray)
Answer: C
Explanation:
Explanation
The Solar Reflectance Index (SRI) is a measure of the roof's ability to reject solar heat, as shown by a small temperature rise. It is defined so that a standard black (reflectance 0.05, emittance 0.90) is 0 and a standard white (reflectance 0.80, emittance 0.90) is 100. SRI is calculated using the roof surface's Solar Reflectance (SR) and Thermal Emittance (TE). SR is the fraction of solar energy that is reflected by the roof, and TE is the relative ability of the roof surface to radiate heat. Therefore, SRI includes the measure of a material's ability to reflect solar radiation, but not its ability to absorb or emit thermal radiation.

NEW QUESTION # 53
A design team is working on a new building project and is employing an integrated, whole-building approach.
Thearchitects want to increase the size of a glazed opening on the south facing wall. Which team members are first affected by this change?
- A. Facility managers
- B. Landscape architects
- C. Civil engineers
- D. Mechanical engineers
Answer: D
Explanation:
Explanation
According to the LEED v4: Building Design and Construction Guide, an integrated, whole-building approach is a process that requires collaboration and communication among all project team members and stakeholders throughout all phases of a project, from pre-design to occupancy and operations.The goal of this approach is to optimize the environmental and human health performance of a building as a whole, rather than focusing on individual components or systems1.
One of the benefits of an integrated, whole-building approach is that it allows the project team to identify and evaluate the interrelationships and trade-offs among various design strategies and decisions, and to optimize the synergies and minimize the conflicts among them1.For example, increasing the size of a glazed opening on the south facing wall may have implications for the daylighting, solar heat gain, thermal comfort, energy use, and mechanical system design of the building2.Therefore, the team members who are first affected by this change are the mechanical engineers, who are responsible for designing the heating, ventilation, and air conditioning (HVAC) system of the building, and ensuring that it meets the thermal comfort and energy performance requirements of the project3.The mechanical engineers may need to adjust the size, type, and location of the HVAC equipment, ductwork, and controls, as well as perform energy modeling and analysis to evaluate the impact of the change on the building's energy consumption and emissions3.The mechanical engineers may also need to coordinate with the architects, lighting designers, and other team members to ensure that the change does not compromise the other design goals and criteria of the project3.
