How is credit earned under Regional Priority Credit, Regional Priority when the credit has multiple thresholds?
Answer(s): C
The LEED for Homes Rating System (v4) includes Regional Priority (RP) Credits, which provide bonus points for achieving existing credits identified as environmentally significant for a project's region. For credits with multiple thresholds, exemplary performance can earn additional points. According to the LEED Reference Guide for Homes Design and Construction (v4):Regional Priority Credits (14 points)Regional Priority Credits are awarded for achieving designated credits that address location-specific environmental priorities. For credits with multiple thresholds (e.g., Water Efficiency Credit: Outdoor Water Use), an additional bonus point is awarded when the maximum threshold has been exceeded, demonstrating exemplary performance.Source: LEED Reference Guide for Homes Design and Construction, v4, Regional Priority Credits, p.190; Innovation Credit: Innovation, p. 190.The LEED v4.1 Residential BD+C rating system confirms:Regional Priority CreditsWhen an RP credit has multiple thresholds, a project earns the bonus point by meeting the base credit requirements, and an additional point may be earned for exemplary performance by exceeding the maximum threshold of the underlying credit. Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online. The correct answer is points are awarded when the maximum threshold has been exceeded (OptionC), as RP credits with multiple thresholds award bonus points for exemplary performance beyond the highest threshold.Why not the other options?A . Points are awarded at the minimum threshold: RP credits require achieving the base credit, not just the minimum threshold.B . Points are awarded at the maximum threshold: Points are awarded for exceeding the maximum threshold, not just meeting it.D . Points are awarded at particular levels of achievement: This is too vague; exemplary performance beyond the maximum threshold is required.

A project team for a home in a small town is pursuing LEED certification. The home is designed with the following site characteristics:· The lot is square.· Three sides of the square lot border undeveloped land. · The previous home covering 78% of the lot is deconstructed and the new LEED home will be built in its place.· One full side of the square lot borders a home that was built 10 years before the LEED project. Compliance with which of the following options, if any, will qualify the home for Location and Transportation Credit, Site Selection?
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 (13 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 SelectionA 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.

For a two-bedroom unit in a multi-family building, a kitchen's minimum airflow requirement for intermittent local exhaust is:
Answer(s): A
The LEED for Homes Rating System (v4) addresses kitchen ventilation requirements in the Indoor Environmental Quality (EQ) Prerequisite: Ventilation, which references ASHRAE Standard 62.2-2010 for minimum airflow rates in residential buildings, including multi-family units. According to the LEED Reference Guide for Homes Design and Construction (v4):EQ Prerequisite: VentilationFor intermittent local exhaust in kitchens, ASHRAE Standard 62.2-2010 requires a minimum airflow rate of 100 cfm (47 lps) for each kitchen to effectively remove cooking-related pollutants and moisture, regardless of the number of bedrooms.Source: LEED Reference Guide for Homes Design and Construction, v4, Indoor Environmental Quality Prerequisite: Ventilation, p. 142.The LEED v4.1 Residential BD+C rating system confirms:EQ Prerequisite: VentilationIntermittent local exhaust in kitchens must provide at least 100 cfm (47 lps) per ASHRAE 62.2-2010 to ensure adequate ventilation in multi-family units, including two-bedroom units. Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online. The correct answer is 100 cfm (47 lps) (Option A), as this is the minimum airflow requirement for intermittent kitchen exhaust per ASHRAE 62.2-2010.Why not the other options?B . 200 cfm (94 lps): This exceeds the minimum requirement for intermittent kitchen exhaust. C . 1 cfm per ft² (5.08 lps per m²): Kitchen exhaust is not based on floor area but on a fixed rate (100 cfm).D . 2.5 cfm per ft² (12.7 lps per m²): This is also not based on floor area and is incorrect for kitchen exhaust.
