LEED-AP-Homes Exam Dumps : LEED AP Homes (Residential) Exam

TheLEED for Homes Rating System (v4)addresses rainwater harvesting in theSustainable Sites (SS) Credit: Rainwater Management, which aims to reduce runoff and its environmental impacts, particularly in areas with significant rainfall events.

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

SS Credit: Rainwater Management (1–3 points)

Rainwater harvesting systems (e.g., rain barrels, cisterns) capture and store rainwater, reducing runoff volume and mitigating on-site erosion, especially during substantial rainfall spikes, by preventing excessive water flow across the site.

A key benefit of rainwater harvesting is mitigating on-site erosion by capturing runoff, particularly in areas with heavy rainfall, reducing soil displacement and environmental damage.

The correct answer ismitigates on-site erosion(Option A), as rainwater harvesting reduces runoff, preventing erosion during rainfall spikes.

TheLEED for Homes Rating System (v4)includes theIndoor Environmental Quality (EQ) Credit: Radon Control, which promotes radon-resistant construction techniques to mitigate the health risks of radon gas, a naturally occurring radioactive gas that can accumulate in homes.

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

EQ Credit: Radon Control (1 point)

Install a passive or active radon-resistant system, including a vent pipe extending from below the foundation (e.g., sub-slab or crawlspace) to the roof to exhaust radon gases before they enter the home. This is a primary radon-resistant construction technique.

TheLEED v4.1 Residential BD+Crating system confirms:

EQ Credit: Radon Control

A vent pipe to exhaust gases from under the home (e.g., sub-slab depressurization system) is a key radon-resistant technique, preventing radon entry into living spaces.

The correct answer isvent pipe to exhaust gases from under the home(Option A), as this is a standard radon-resistant technique, typically involving a sub-slab depressurization system with a vent pipe.

TheLEED for Homes Rating System (v4)includes theMaterials and Resources (MR) Prerequisite: Certified Tropical Wood, which ensures that wood used in LEED projects is sourced sustainably to protect tropical ecosystems.

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

MR Prerequisite: Certified Tropical Wood

All new wood in the project must be nontropical, reused, reclaimed, or certified by the Forest Stewardship Council (FSC). Tropical wood, if used, must be FSC-certified. This prerequisite ensures that wood sourcing does not contribute to deforestation in ecologically sensitive regions.

TheLEED v4.1 Residential BD+Crating system confirms:

MR Prerequisite: Certified Tropical Wood

All wood must be nontropical, reused, reclaimed, or FSC-certified. Tropical wood is only permitted if it is FSC-certified.

To comply, all wood must benon-tropical, reused, reclaimed, or certified(Option A), ensuring sustainable sourcing across all wood types used in the project.
