Placing grilles, grates or mats at all major entrances is an example of permanent entryway systems used to reduce dust, dirt and contaminants brought into a facility. Permanent entryway systems are designed to capture dirt and particulates from people’s shoes and prevent them from entering the indoor environment. This improves the indoor air quality and reduces the need for cleaning and maintenance. The LEED Green Associate Candidate Handbook states that one of the strategies for achieving indoor environmental quality is to “use permanent entryway systems (grilles, grates, mats) to reduce particulate matter being brought into buildings at regular entryways” [1, p. 16]. References: LEED Green Associate Candidate Handbook, [Indoor Environmental Quality | U.S. Green Building Council]

This formula is used to calculate the percentage of restoration area for the LEED v4 credit SSc2: Protect or Restore Habitat1. The restoration area is the portion of the site that is restored with native or adapted vegetation, and the total previously disturbed site area is the area that was altered by human activity before the project2.

The U.S. Green Building Council (USGBC) administers the LEED rating systems development. The LEED rating systems are frameworks that provide guidance and criteria for designing, constructing, operating, and maintaining green buildings. The USGBC is responsible for developing, maintaining, and updating the LEED rating systems through a consensus-based process that involves various stakeholders, such as technical experts, industry leaders, government representatives, and public comments. The LEED Green Associate Candidate Handbook states that “USGBC is committed to transforming the way our buildings are designed, constructed and operated through LEED” [1, p. 7]. References: LEED Green Associate Candidate Handbook, [LEED Rating Systems | U.S. Green Building Council]

Low-emitting materials are those that have minimal or no emissions of volatile organic compounds (VOCs) and other harmful pollutants that can affect indoor air quality (IAQ)1. Specifying and installing low-emitting materials at the source can help prevent the negative effects of indoor pollutants by reducing the exposure of occupants and workers tothese substances2. Some examples of low-emitting materials are paints, coatings, adhesives, sealants, flooring, furniture, and insulation that meet the criteria of third-party certification programs such as Green Seal, Greenguard, or SCS3.
