Important US Green Building Council LEED-AP-Homes Exam Questions

Answer: A

Explanation:

The LEED for Homes Rating System (v4) addresses fireplaces in the Indoor Environmental Quality (EQ) Credit: Enhanced Combustion Venting, which promotes safe combustion practices to prevent indoor air quality issues from fireplaces.

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

EQ Credit: Enhanced Combustion Venting (1 point)

For fireplaces, install doors and ensure they are direct-vented or power-vented to prevent combustion byproducts from entering the home. Unvented fireplaces or appliances are not permitted due to indoor air quality risks.

Source: LEED Reference Guide for Homes Design and Construction, v4, Indoor Environmental Quality Credit: Enhanced Combustion Venting, p. 144.

The LEED v4.1 Residential BD+C rating system confirms:

EQ Credit: Enhanced Combustion Venting

Fireplaces must have doors and be vented to the outdoors (e.g., direct-vent) to qualify for the credit, ensuring safe operation and minimal indoor air pollution.

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

The correct answer is install doors on the fireplace (Option A), as this, combined with proper venting (assumed in LEED-compliant fireplaces), ensures safe operation and compliance with the credit.

Why not the other options?

B . Use unvented combustion appliances: Unvented appliances are prohibited due to the risk of combustion byproducts like carbon monoxide entering the home.

C . Use an unvented decorative log fireplace: Unvented fireplaces are not allowed, as they pose significant indoor air quality risks.

D . Install carbon monoxide monitors in each room: While monitors are recommended for safety, they do not address the credit's requirement for vented fireplaces with doors.

The LEED AP Homes Candidate Handbook emphasizes EQ credits, including combustion venting, and references the LEED Reference Guide for Homes Design and Construction as a key resource. The exam is based on LEED v4, ensuring the relevance of fireplace doors.

Answer: C

Explanation:

The LEED for Homes Rating System (v4) includes a Home Size Adjustment as part of the point-scoring system to account for the environmental impact of larger homes, which typically use more resources and energy. This adjustment is applied across the project's total points and is calculated based on conditioned floor area and the number of bedrooms.

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

Home Size Adjustment

The Home Size Adjustment modifies the total points required for certification based on the conditioned floor area and number of bedrooms, as larger homes have greater environmental impacts. The adjustment is applied to the overall point threshold, not to a specific credit, but it aligns with credits like Indoor Environmental Quality (EQ) Credit: No Environmental Tobacco Smoke, which ensures indoor air quality in larger homes.

Source: LEED Reference Guide for Homes Design and Construction, v4, Introduction, p. 24.

The LEED v4.1 Residential BD+C rating system confirms:

Home Size Adjustment

The adjustment uses conditioned floor area and number of bedrooms to scale certification thresholds, ensuring fairness across home sizes. It impacts the overall certification process, particularly in relation to credits like EQ Credit: No Environmental Tobacco Smoke, which addresses indoor air quality in larger spaces.

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

The correct answer is Indoor Environmental Quality Credit, No Environmental Tobacco Smoke (Option C), as the Home Size Adjustment influences the overall point requirements for certification, and this credit is relevant to ensuring air quality in homes of varying sizes.

Why not the other options?

A . Water Efficiency Credit, Indoor Water Use: This credit focuses on fixture efficiency and water use calculations, not directly tied to home size adjustment.

B . Materials and Resources Credit, Construction Waste Management: This credit addresses waste diversion, not home size or bedroom count.

D . Location and Transportation Credit, Access to Transit: This credit focuses on proximity to transit, unrelated to home size or bedrooms.

The LEED AP Homes Candidate Handbook emphasizes the Home Size Adjustment as part of the certification process and references the LEED Reference Guide for Homes Design and Construction as a key resource. The exam is based on LEED v4, ensuring the relevance of this adjustment.

Answer: C

Explanation:

The LEED for Homes Rating System (v4) includes the Location and Transportation (LT) Credit: Site Selection, Option 3: Open Space, which encourages projects to be located near publicly accessible open spaces to promote recreation and environmental benefits.

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

LT Credit: Site Selection, Option 3: Open Space (1 point)

Locate the project within a 1/2-mile (0.8-kilometer) walking distance of a publicly accessible open space that is at least 0.75 acre (0.3 hectare) in size. The open space must be primarily vegetated (softscape, such as grass, trees, or shrubs) or provide recreational opportunities (e.g., playgrounds, trails). Acceptable open spaces include parks, playgrounds, or nature preserves, but not water bodies or privately restricted areas.

Source: LEED Reference Guide for Homes Design and Construction, v4, Location and Transportation Credit: Site Selection, p. 55.

The LEED v4.1 Residential BD+C rating system confirms:

LT Credit: Site Selection, Option 3: Open Space

The open space must be at least 0.75 acre (0.3 hectare), publicly accessible, and within 1/2 mile (0.8 km) of the project. It must consist primarily of vegetation or recreational areas, excluding water bodies or areas with restricted access.

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

Evaluation of options:

A . 1/2 mi. (0.8 km) of a 3/4 acre (0.3 hectare) cornfield: A cornfield is agricultural land, not a publicly accessible recreational or vegetated open space as defined by LEED, so it does not qualify.

B . 3/4 mi. (1.2 km) of a publicly accessible park that is 3/4 acre (0.3 hectare) in size: The distance (3/4 mi.) exceeds the 1/2-mile (0.8 km) requirement, so it does not qualify.

C . 1/2 mi. (0.8 km) of a pond surrounded by a 1/2 acre (0.2 hectare) walkway, and across the street from a 1/4 acre (0.1 hectare) publicly accessible park: The pond is excluded (water bodies do not qualify), and the walkway (0.2 hectare) and park (0.1 hectare) together total 0.3 hectare (0.75 acre), meeting the size requirement within 1/2 mile. Assuming the walkway is vegetated or recreational, this qualifies.

D . 3/4 mi. (1.2 km) of a 1/4 acre (0.1 hectare) publicly accessible park, across the street from a 1/4 acre (0.1 hectare) lot which is private land open to the public: The distance (3/4 mi.) exceeds 1/2 mile, and the combined area (0.2 hectare) is below 0.3 hectare. Private land, even if publicly accessible, may not fully qualify without clear documentation.

The correct answer is Option C, as it meets the 1/2-mile distance and the combined 0.75-acre size requirement, assuming the walkway is vegetated or recreational.

The LEED AP Homes Candidate Handbook emphasizes LT credits, including Site Selection, and references the LEED Reference Guide for Homes Design and Construction as a key resource. The exam is based on LEED v4, ensuring the relevance of open space criteria.

Answer: B

Explanation:

The LEED for Homes Rating System (v4) includes the Location and Transportation (LT) Credit: Site Selection, which awards points for building on infill or previously developed sites to minimize environmental impact.

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

LT Credit: Site Selection (1--3 points)

Option 1: Infill: At least 75% of the lot's perimeter must border previously developed parcels (e.g., existing buildings or infrastructure).

Option 2: Previously Developed: The lot must have been previously altered by construction (e.g., a prior home covering a significant portion of the site) before the LEED project.

A site with a previous home covering 78% of the lot qualifies as previously developed, but if only one side (25% of a square lot's perimeter) borders a developed parcel, it does not meet the infill requirement.

Source: LEED Reference Guide for Homes Design and Construction, v4, Location and Transportation Credit: Site Selection, p. 54.

The LEED v4.1 Residential BD+C rating system confirms:

LT Credit: Site Selection

A site qualifies for Option 2: Previously Developed if it was previously altered (e.g., a home covering 78% of the lot). Infill requires 75% of the perimeter to border developed land, which a square lot with only one developed side (25%) does not meet.

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

Evaluation:

Infill: The lot is square, with one side (25% of the perimeter) bordering a developed home. This does not meet the 75% perimeter requirement for infill.

Previously Developed: The previous home covered 78% of the lot, qualifying it as previously developed.

The correct answer is Previously Developed only (Option B), as the site meets the criteria for Option 2 but not Option 1.

Why not the other options?

A . Infill only: The site does not meet the 75% perimeter requirement for infill (only 25% borders developed land).

C . Infill and Previously Developed: The site does not qualify for infill, so it cannot meet both options.

D . None, this home does not comply: The site qualifies for Previously Developed due to the prior home.

The LEED AP Homes Candidate Handbook emphasizes LT credits, including site selection, and references the LEED Reference Guide for Homes Design and Construction as a key resource. The exam is based on LEED v4, ensuring the relevance of previously developed sites.

Answer: B

Explanation:

The LEED for Homes Rating System (v4) includes the Location and Transportation (LT) Credit: Community Resources and Services, which awards points for locating a project near or integrating community services to reduce transportation needs, particularly in multi-family buildings.

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

LT Credit: Community Resources and Services (1--2 points)

In multi-family buildings, provide access to community services (e.g., retail, grocery, pharmacy) within the development or within 1/4 mile (0.4 km) walking distance. Including retail on the street level of the development contributes to earning points by enhancing access to services for residents.

Source: LEED Reference Guide for Homes Design and Construction, v4, Location and Transportation Credit: Community Resources and Services, p. 56.

The LEED v4.1 Residential BD+C rating system confirms:

LT Credit: Community Resources and Services

Providing retail on the street level of a multi-family building qualifies as a strategy to meet the credit by integrating community resources directly within the project, reducing resident travel.

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

The correct answer is retail on the street level of the development (Option B), as this directly enhances access to community services, contributing to the credit's requirements.

Why not the other options?

A . Shared parking with an adjacent single-family development: Parking strategies may support LT Credit: Compact Development, but they do not directly provide community services.

C . Additional parking for adjacent retail developments: This does not enhance resident access to services within the project or nearby.

D . Shuttle service for the residents to their places of employment: Shuttle services may support LT Credit: Access to Quality Transit, but not Community Resources and Services.

The LEED AP Homes Candidate Handbook emphasizes LT credits, including Community Resources and Services, and references the LEED Reference Guide for Homes Design and Construction as a key resource. The exam is based on LEED v4, ensuring the relevance of retail integration.
