USGBC LEED-Green-Associate Exam With Confidence Using Practice Dumps

The increase in air temperature in a developed area resulting from the dark surfaces of roadways, parking lots, and tarred rooftops is known as heat island effect. Heat island effect is a phenomenon whereby urban areas experience higher temperatures than rural areas due to the absorption and re-emission of solar heat by man-made surfaces. Heat island effect can have negative impacts on human health, energy consumption, air quality, and climate change. Some strategies to reduce heat island effect include increasing vegetation cover, using reflective or green roofs, using cool or permeable pavements, and enhancing natural ventilation.References: LEED v4 BD+C Reference Guide, Sustainable Sites, page 35 ; EPA Heat Island Effect website 1

Prerequisites and credits are the two types of requirements that make up the LEED rating system. Prerequisites are the basic elements or strategies that must be included in any LEED certified project, regardless of the rating system or the level of certification1. Credits are the additional elements or strategies that can be included in a LEED project to achieve higher levels of performance and certification1. Credits are optional and have different point values depending on their environmental benefits and impacts2. Therefore, the correct answer is B. Prerequisites are mandatory and credits are optional.

 In the commercial LEED rating systems, achieving 40-49 points will result in Silver level certification. The points are awarded based on how well the project meets various sustainability criteria set out in the LEED rating system. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources
