Pass LEED-Green-Associate Exam Guide

Installing a bioswale is a design technique that should be used to help prevent stormwater damage to the building and surrounding site. A bioswale is a vegetated channel that conveys stormwater runoff while filtering pollutants, reducing peak flow rates, increasing infiltration, and providing habitat. A bioswale can help prevent stormwater damage by reducing erosion, flooding, sedimentation, and contamination of waterways. The other options are not design techniques that should be used to help prevent stormwater damage to the building and surrounding site. Directing runoff into a stream is a design technique that can cause stormwater damage by increasing the volume and velocity of water entering the stream, resulting in erosion, flooding, sedimentation, and contamination of the stream. Paving the site with high Solar Reflectance Index (SRI) material is a design technique that can reduce the heat island effect by reflecting more solar radiation than conventional paving materials, but it does not prevent stormwater damage as it does not reduce runoff or improve water quality. Paving the site with impervious material is a design technique that can cause stormwater damage by preventing infiltration and increasing runoff, resulting in erosion, flooding, sedimentation, and contamination of waterways. References: LEED Green Associate Candidate Handbook, page 32; USGBC [Sustainable Sites], page 4-5.

LEED impact categories are the environmental, social, and economic issues that LEED projects aim to address1. They provide an overview of the market transformation that technical requirements work to achieve, as well as a guide to where points should be assigned2. The categories focus on LEED’s social, environmental, and economic goals, and they assess each strategy based on its ability to achieve those goals3.

The footprint of a building is the area of ground that it covers, defined by its perimeter. It’s essentially the shape that results when you trace around the outer walls of a building plan. This term is used in architecture and urban planning to describe the space that a building occupies on a site. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

The minimum program requirements (MPRs) are the basic characteristics that a project must possess in order to be eligible for LEED certification. One of the MPRs for the LEED for New Construction and Major Renovations Rating System is to comply with the minimum project size, which is defined as having a gross floor area of at least 1,000 square feet (93 square meters) that is capable of achieving a minimum level of energy efficiency13. References: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide3
