TheLEED for Homes Rating System (v4)includes theIndoor Environmental Quality (EQ) Credit: Contaminant Control, Option 2: Shoe Removal and Storage, which aims to reduce indoor contaminants by providing a designated area for shoe removal and storage to prevent tracking pollutants into living spaces.

According to theLEED Reference Guide for Homes Design and Construction (v4):

EQ Credit: Contaminant Control, Option 2: Shoe Removal and Storage (1–2 points)

Provide a designated shoe removal and storage area near the primary entryway, separated from living spaces by a door or other barrier to prevent contaminants from entering the home. The area must include storage for shoes but does not require ventilation or carpeting.

TheLEED v4.1 Residential BD+Crating system confirms:

EQ Credit: Contaminant Control, Option 2: Shoe Removal and Storage

The shoe storage area must be separated from living spaces to prevent the spread of contaminants, typically with a door or partition, and does not require specific ventilation or carpeting.

The correct answer isarea must be separated from the living space(Option A), as this is a key requirement to ensure contaminants are contained outside living areas.

Why not the other options?

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.

The shower compartment is 3,750 in² (2.4 m²), exceeding the 2,500 in² limit. Therefore,multiple showerheads are not allowed(Option C), as LEED restricts multiple heads in oversized compartments to ensure water efficiency.

Why not the other options?

The question references an "Energy and Atmosphere Prerequisite" for education, which appears to be a misnomer, as theLEED for Homes Rating System (v4)includes this requirement under theInnovation (IN) Prerequisite: Education of the Homeowner, Tenant, or Building Manager. This prerequisite ensures occupants receive materials to understand and maintain the home’s sustainable features.

According to theLEED Reference Guide for Homes Design and Construction (v4):

IN Prerequisite: Education of the Homeowner, Tenant, or Building Manager

Provide an operations and maintenance manual to the homeowner or tenant, including product manuals for installed equipment (e.g., HVAC, water heating systems) and information on the operation and maintenance of green features.

TheLEED v4.1 Residential BD+Crating system confirms:

IN Prerequisite: Education of the Homeowner or Tenant

An operations and maintenance manual must be provided to occupants, detailing the function, operation, and maintenance of sustainable systems and equipment in the home.

The correct answer isoperations and maintenance manual(Option B), as this is the required written material to comply with the prerequisite.
