USGBC LEED-AP-Homes Dumps

TheLEED for Homes Rating System (v4)encourages planning for energy-efficient and sustainable technologies during the design phase, particularly for significant electrical loads that impact infrastructure, as addressed in credits likeEnergy and Atmosphere (EA) Credit: Optimize Energy Performance.

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

EA Credit: Optimize Energy Performance

Design the home to accommodate high-efficiency systems and emerging technologies, such as electric vehicle (EV) charging stations, which require dedicated electrical capacity (e.g., 240-volt circuits) and planning during the design phase to ensure adequate panel capacity and conduit placement.

TheLEED v4.1 Residential BD+Crating system confirms:

EA Credit: Optimize Energy Performance

Electric vehicle charging stations require special consideration in the design phase, including dedicated circuits and infrastructure to support high-voltage, high-amperage loads, ensuring future scalability and energy efficiency.

Anelectric vehicle charging station(Option D) requires special consideration during the design phase due to its high power demand (typically 240 volts, 30–50 amps), necessitating dedicated circuits, panel capacity upgrades, and potential conduit or wiring planning to avoid costly retrofits.

TheLEED for Homes Rating System (v4)outlines the requirements for theMaterials and Resources (MR) Credit: Environmentally Preferable Products, which encourages the use of sustainable materials. The credit has two options:Option 1: Local Production(materials sourced within 100 miles) andOption 2: Environmentally Preferable Products(materials with attributes like recycled content, FSC-certified wood, or low emissions).

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

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

Earn points by meeting the following:

Option 2: Environmentally Preferable Products: Use products that meet one or more of the following criteria for at least 25% (1 point), 50% (2 points), or 90% (3–4 points) by cost of the total materials:

Recycled content

FSC-certified wood

Bio-based materials

Low-emission products (e.g., low-VOC paints)To earn 1 point, at least 25% of the materials (by cost) must meet two or more of these criteria.Source: LEED Reference Guide for Homes Design and Construction, v4, Materials and Resources Credit: Environmentally Preferable Products, p. 160–161.

TheLEED v4.1 Residential BD+Crating system confirms:

MR Credit: Environmentally Preferable Products

For 1 point, use products that meet two or more environmentally preferable criteria (e.g., recycled content, FSC-certified) for at least 25% of the total material cost.

To earnone pointunder Option 2, the project must use materials that collectively meettwo or moreof the environmentally preferable criteria (e.g., a product with both recycled content and low emissions) for at least 25% of the total material cost. This makesOption Bthe correct answer.

TheLEED for Homes Rating System (v4)requires proper sizing of space heating and cooling systems to ensure energy efficiency, addressed in theEnergy and Atmosphere (EA) Prerequisite: Minimum Energy Performanceand related credits.

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

EA Prerequisite: Minimum Energy Performance

Size heating and cooling systems in accordance with ACCA Manual J (Residential Load Calculation). This ensures that HVAC systems are appropriately sized for the home’s thermal loads, improving energy efficiency and occupant comfort.

TheLEED v4.1 Residential BD+Crating system confirms:

EA Prerequisite: Energy Performance

Use ACCA Manual J to calculate heating and cooling loads and properly size HVAC equipment to meet LEED requirements.
