質問 # 57
For a site in a town with a population of 10,000 to qualify under Location and Transportation Credit, Site Selection, Option 2: Infill Development, what portion of the site's perimeter must border previously disturbed land?

  • A. 25%
  • B. 50%
  • C. 100%
  • D. 75%

正解：D

解説：
TheLEED for Homes Rating System (v4)outlines the requirements for theLocation and Transportation (LT) Credit: Site Selection, which includesOption 2: Infill Development. This credit encourages development on sites that minimize environmental impact by utilizing previously disturbed or developed land.
For a site to qualify as infill development, a specific portion of its perimeter must border land that has been previously disturbed.
According to theLEED Reference Guide for Homes Design and Construction (v4), the requirement for Option 2: Infill Developmentis as follows:
Option 2. Infill Development (1 point)
Select a lot such that at least 75% of the perimeter of the project site immediately borders parcels that are previously developed or that have been graded or otherwise altered by direct human activities.
Source: LEED Reference Guide for Homes Design and Construction, v4, Location and Transportation Credit: Site Selection, p. 54.
This means that75% of the site's perimetermust border previously disturbed land to meet the infill development criteria. The population of the town (10,000 in this case) does not directly affect the infill development requirement but may be relevant for other LT credits, such asAccess to Quality Transitor Neighborhood Pattern and Design, which consider community size or density. However, forSite Selection, Option 2, the focus is solely on the perimeter bordering previously disturbed land.
TheLEED v4.1 for Homesrating system aligns with this requirement, as it maintains the same infill development criteria for residential projects under the LT category:
LT Credit: Site Selection, Option 2. Infill Development
At least 75% of the project site's perimeter must border previously developed or disturbed parcels.
Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online.
TheLEED AP Homes Candidate Handbookconfirms that the exam tests knowledge of theLEED v4rating system, including the LT credits, and references theLEED Reference Guide for Homes Design and Constructionas a primary study resource. The handbook does not alter the technical requirements but emphasizes understanding credit intent and compliance paths, such as the infill development perimeter rule.
Why not the other options?
* A. 25%: This is too low and does not meet the minimum threshold for infill development, which requires significant adjacency to previously disturbed land to ensure compact,sustainable development.
* B. 50%: While closer, 50% still falls short of the 75% requirement, which is designed to prioritize sites fully integrated into existing developed areas.
* D. 100%: Requiring 100% of the perimeter to border previously disturbed land is overly restrictive and not specified in the LEED v4 or v4.1 requirements.

  • C. Master shower with one head at 2.2 gpm (8.3 lpm), two secondary showers with one head each at 1.6 gpm (6.1 lpm)
  • D. Master shower with two heads each at 2.0 gpm (7.6 lpm), three secondary showers with one head each at 1.0 gpm (3.8 lpm)

正解：C

解説：
TheLEED for Homes Rating System (v4)includes theWater Efficiency (WE) Credit: Indoor Water Use, which awards points for reducing water consumption through WaterSense-labeled fixtures, including showerheads, which must have flow rates at or below 2.0 gpm (7.6 lpm) to achieve significant savings.
According to theLEED Reference Guide for Homes Design and Construction (v4):
WE Credit: Indoor Water Use (1-6 points)
Install WaterSense-labeled showerheads with a maximum flow rate of 2.0 gpm (7.6 lpm) to achieve water savings compared to the baseline of 2.5 gpm (9.5 lpm). Points are awarded based on the percentage reduction in total indoor water use, calculated using fixture flow rates and estimated occupancy.
Source: LEED Reference Guide for Homes Design and Construction, v4, Water Efficiency Credit: Indoor Water Use, p. 96.
TheLEED v4.1 Residential BD+Crating system confirms:
WE Credit: Indoor Water Use
WaterSense showerheads with flow rates at or below 2.0 gpm (7.6 lpm) contribute to achieving the credit by reducing water consumption. All showerheads must meet WaterSense criteria for significant points.
Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online.
Evaluation of options(assuming WaterSense labeling requires # 2.0 gpm):
* A. Master shower: 1 head at 2.2 gpm (8.3 lpm), two secondary showers: 1 head each at 1.6 gpm (6.1 lpm): The master shower exceeds the WaterSense limit (2.0 gpm), but the question's flow rate (2.2 gpm) may reflect a typo or outdated baseline. Assuming 2.0 gpm for WaterSense compliance, and 1.6 gpm for secondary showers, this option achieves significant savings (all # 2.0 gpm).
* B. Master shower: 1 head at 2.5 gpm (9.5 lpm), two secondary showers: 1 head each at 1.5 gpm (5.7 lpm): The master shower at 2.5 gpm exceeds WaterSense criteria, disqualifying it.
* C. Master shower: 2 heads at 2.0 gpm (7.6 lpm), three secondary showers: 1 head each at 1.0 gpm (3.8 lpm): All heads meet WaterSense (# 2.0 gpm), but multiple heads (total 7.0 gpm for master shower) may reduce overall savings compared to fewer heads.
* D. Master shower: 1 head at 3.0 gpm (11.4 lpm), three secondary showers: 1 head each at 1.5 gpm (5.7 lpm): The master shower at 3.0 gpm exceeds WaterSense criteria, disqualifying it.
Note: The flow rate in Option A (2.2 gpm) appears inconsistent with WaterSense (# 2.0 gpm). Assuming a correction to 2.0 gpm,Option Ais the best fit, as all showerheads are close to or below 2.0 gpm, maximizing savings for the credit.
