Authentic USGBC Certification Exam LEED-AP-Homes Questions Answers

TheLEED for Homes Rating System (v4)addresses minimum outdoor air ventilation requirements in theIndoor Environmental Quality (EQ) Prerequisite: Ventilation, which ensures adequate indoor air quality through proper ventilation design.

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

EQ Prerequisite: Ventilation

Meet the minimum outdoor air ventilation requirements of ASHRAE Standard 62.2-2010, Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings. This standard specifies minimum ventilation rates and other measures to provide acceptable indoor air quality in residential buildings.

TheLEED v4.1 Residential BD+Crating system confirms:

EQ Prerequisite: Ventilation

Comply with ASHRAE Standard 62.2-2010 for minimum outdoor air ventilation rates in single-family and low-rise multifamily homes to ensure healthy indoor air quality.

The correct answer isASHRAE Standard 62.2-2010(Option C), as it is the specific standard referenced for minimum ventilation requirements in LEED for Homes.

Why not the other options?

TheLEED for Homes Rating System (v4)includes theIndoor Environmental Quality (EQ) Credit: Enhanced Combustion Venting, which awards points for minimizing indoor air quality risks from combustion appliances, including fireplaces. Avoiding combustion appliances altogether is the most effective way to achieve the maximum credit.

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

EQ Credit: Enhanced Combustion Venting (1 point)

To achieve the maximum credit, install no combustion appliances, including fireplaces, to eliminate the risk of combustion byproducts (e.g., carbon monoxide) entering the home. If fireplaces are installed, they must be direct-vented or power-vented with doors. EPA-certified woodstoves or factory-built fireplaces with catalytic combustors reduce emissions but do not achieve the maximum credit compared to no fireplace.

TheLEED v4.1 Residential BD+Crating system confirms:

EQ Credit: Enhanced Combustion Venting

The highest level of compliance is achieved by installing no combustion appliances, including fireplaces. If fireplaces are used, they must be sealed and vented, but avoiding fireplaces maximizes indoor air quality protection.

Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online.

The correct answer isinstall no fireplace(Option A), as this eliminates combustion risks entirely, achieving the maximum credit for Enhanced Combustion Venting.

Why not the other options?

TheLEED for Homes Rating System (v4)requires a walk-through as part of theInnovation (IN) Prerequisite: Education of the Homeowner, Tenant, or Building Managerto educate occupants on the operation and maintenance of sustainable systems.

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

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

Conduct a minimum two-hour walk-through with the homeowner, including:

Identification of all installed equipment (e.g., HVAC, water heating systems).

Instruction on how to use and operate the equipment and green measures.

Information on how to maintain the equipment to ensure ongoing performance.Information on product return policies or rebates is not required.Source: LEED Reference Guide for Homes Design and Construction, v4, Innovation Prerequisite: Education of the Homeowner, Tenant, or Building Manager, p. 188.

TheLEED v4.1 Residential BD+Crating system confirms:

IN Prerequisite: Education of the Homeowner or Tenant

The walk-through must cover equipment identification, operation, and maintenance instructions, but does not include product return policies or rebates.

Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online.

The correct answer isinformation related to product return policies and rebates(Option D), as this is not a required component of the walk-through.

Why not the other options?

A. Identification of all installed equipment: This is required to familiarize occupants with sustainable systems.

B. Instruction in how to use the measures and operate the equipment: This is required to ensure proper operation.
