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

TheLEED for Homes Rating System (v4)includes theEnergy and Atmosphere (EA) Credit: Windows, which sets performance requirements for windows to balance energy efficiency with design goals, such as large glazing areas for views. Higher window-to-wall ratios require more stringent performance to mitigate heat loss or gain.

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

EA Credit: Windows (1–3 points)

Meet the prescriptive window performance requirements based on the window-to-exterior wall area ratio (WWR). If the WWR exceeds 24%, more stringent U-factor and solar heat gain coefficient (SHGC) values are required to ensure energy efficiency.

TheLEED v4.1 Residential BD+Crating system confirms:

EA Credit: Windows

For projects with a window-to-exterior wall area ratio greater than 24%, windows must meet enhanced performance criteria (e.g., lower U-factor and SHGC) to reduce energy losses.

The correct answer iswindow-to-exterior wall area ratio is greater than 24%(Option C), as this triggers stricter window performance requirements to maintain energy efficiency.

TheLEED for Homes Rating System (v4)promotes the use of native and adapted plants in theWater Efficiency (WE) Credit: Outdoor Water UseandSustainable Sites (SS) Credit: Site Development – Protect or Restore Habitatto reduce maintenance and environmental impacts compared to conventional turf.

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

WE Credit: Outdoor Water Use (1–4 points)

Native and adapted plant species require less maintenance, including decreased frequency of mowing, compared to conventional turf grass, which often needs frequent cutting to maintain appearance.

Source: LEED Reference Guide for Homes Design and Construction, v4, Water Efficiency Credit: Outdoor Water Use, p. 98.

TheLEED v4.1 Residential BD+Crating system confirms:

WE Credit: Outdoor Water Use

Using native and adapted plants reduces maintenance demands, such as mowing frequency, compared to turf grass, while also lowering irrigation needs.

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

The correct answer isdecreased frequency of mowing(Option C), as native and adapted plants typically require less frequent maintenance than turf grass.

TheLEED for Homes Rating System (v4)awards points for theMaterials and Resources (MR) Credit: Environmentally Preferable Productswhen products are reclaimed (reused or salvaged from another project), contributing to the required percentage of material cost (e.g., 25% for 1 point).

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

MR Credit: Environmentally Preferable Products (1–4 points)

Use products that are reused or salvaged from the same or another project for at least 25% (by cost) of the total materials to earn 1 point. Reclaimed products include salvaged architectural elements like stained glass windows, which are reused in their original form.

Source: LEED Reference Guide for Homes Design and Construction, v4, Materials and Resources Credit: Environmentally Preferable Products, p. 160.

TheLEED v4.1 Residential BD+Crating system confirms:

MR Credit: Environmentally Preferable Products

Reclaimed materials, such as salvaged stained glass windows, qualify for points if they contribute to the required material cost percentage (e.g., 25% for 1 point).

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

The correct answer isstained glass window(Option A), as it is a salvaged architectural element commonly reused in its original form, qualifying as a reclaimed material under the credit.
