A home has a large shower compartment of 3,750 in² (2.4 m²) with dual 1.5 gpm (5.6 lpm) shower heads. How should the flow rate be calculated?
The flow rates are added to total 3.0 gpm (11.2 lpm)
The flow rate is calculated as two separate compartments of 1.5 gpm (5.6 lpm)
Multiple shower heads are not allowed
Shower compartment size does not affect shower head flow rates for LEED compliance
TheLEED for Homes Rating System (v4)addresses shower compartments in theWater Efficiency (WE) Credit: Indoor Water Use, where the size and number of showerheads impact water use calculations.
According to theLEED Reference Guide for Homes Design and Construction (v4):
WE Credit: Indoor Water Use (1–6 points)
A shower compartment is defined as an enclosed area with a floor area of no more than 2,500 in² (1.6 m²), where all fixtures (e.g., multiple showerheads) count as a single fixture for water use calculations. Compartments larger than 2,500 in² are considered multiple compartments, and multiple showerheads in such cases are not allowed for LEED compliance to ensure water efficiency.
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
For shower compartments exceeding 2,500 in² (1.6 m²), multiple showerheads are not permitted to maintain water efficiency goals. Each compartment must be treated separately if applicable, but large compartments cannot have multiple heads.
Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online.

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?
25%
50%
75%
100%
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 forOption 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 TransitorNeighborhood 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.
For a project to earn one point for Materials and Resources Credit, Environmentally Preferable Products, what must occur?
Achieve more than 95% of the component by weight or volume that meets Option 2: Environmentally Preferable Products
Meet more than two or more of the criteria under Option 2: Environmentally Preferable Products
Achieve more than 95% of the component by weight or volume that meets Option 1: Local Production
Meet both Option 1: Local Production and Option 2: Environmentally Preferable Products
TheLEED for Homes Rating System (v4)outlines the requirements for theMaterials and Resources (MR) Credit: Environmentally Preferable Products, which encourages the use of sustainable materials. The credit has two options:Option 1: Local Production(materials sourced within 100 miles) andOption 2: Environmentally Preferable Products(materials with attributes like recycled content, FSC-certified wood, or low emissions).
According to theLEED Reference Guide for Homes Design and Construction (v4):
MR Credit: Environmentally Preferable Products (1–4 points)
Earn points by meeting the following:
Option 2: Environmentally Preferable Products: Use products that meet one or more of the following criteria for at least 25% (1 point), 50% (2 points), or 90% (3–4 points) by cost of the total materials:
Recycled content
FSC-certified wood
Bio-based materials
Low-emission products (e.g., low-VOC paints)To earn 1 point, at least 25% of the materials (by cost) must meet two or more of these criteria.Source: LEED Reference Guide for Homes Design and Construction, v4, Materials and Resources Credit: Environmentally Preferable Products, p. 160–161.
TheLEED v4.1 Residential BD+Crating system confirms:
MR Credit: Environmentally Preferable Products

1 point: 0.5 kW or 5% of annual energy use.
2 points: 1.0 kW or 10% of annual energy use.
3 points: 1.5 kW or 15% of annual energy use.
4 points: 2.0 kW or 20% of annual energy use.The kW values are for photovoltaic systems and assume typical production rates (e.g., 1 kW ≈ 1,500 kWh/year).Source: LEED Reference Guide for Homes Design and Construction, v4, Energy and Atmosphere Credit: Renewable Energy, p. 138.
TheLEED v4.1 Residential BD+Crating system confirms:
EA Credit: Renewable Energy
Points are awarded based on the installed capacity of PV systems (e.g., 2.0 kW for 4 points) or the percentage of energy offset, whichever is higher. A 2000 kWh system (approximately 2.0 kW) qualifies for 4 points.
Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online.
The question states a 1000 kWh PV system earns 2 points, corresponding to approximately 1.0 kW (assuming 1 kW ≈ 1,500 kWh/year). A 2000 kWh system is approximately 2.0 kW (2000 ÷ 1500 ≈ 1.33 kW, but conservatively aligned with the 2.0 kW threshold in LEED), which earns4 points(Option D).
Why not the other options?
A. One point: This corresponds to 0.5 kW, far below a 2000 kWh system.
B. Two points: This is the baseline for a 1000 kWh (1.0 kW) system, not 2000 kWh.
