Which of the following power sources are considered green power?
Correct Answer: B
Explanation Biomass is a renewable energy source that can be used to produce electricity from organic plant and waste material. It is considered green power by the U.S. EPA because it provides environmental benefits and reduces greenhouse gas emissions12.
Question 92
A site with minimal hardscape that has a large permeable surface results in
Correct Answer: A
Explanation A site with minimal hardscape (such as concrete, asphalt, or other impervious surfaces) that has a large permeable surface (such as soil, grass, or other vegetation) results in reduced rainwater runoff. This is because permeable surfaces allow rainwater to infiltrate into the ground, replenishing the groundwater and reducing the amount of water that flows over the surface and carries pollutants into storm drains and waterways. Reducing rainwater runoff is one of the goals of the LEED v4 Location and Transportation category, which offers credits for using strategies such as green roofs, permeable paving, rain gardens, and vegetated swales
Question 93
Which of the following benefits pertain to purchasing and installing locally sourced. environmentally preferable products?
Correct Answer: C
Explanation The environmental harm associated with transportation is reduced when purchasing and installing locally sourced, environmentally preferable products. Locally sourced products are products that are extracted, harvested, recovered, or manufactured within a certain distance from the project site. Environmentally preferable products are products that have reduced environmental impacts compared to similar products in terms of energy use, water use, materials use, waste generation, emissions, toxicity, and durability. Purchasing and installing locally sourced, environmentally preferable products reduces the amount of fuel consumption, greenhouse gas emissions, air pollution, and road congestion associated with transporting products over long distances. The LEED Green Associate Candidate Handbook states that one of the strategies for achieving materials and resources efficiency is to "use local or regional materials (extracted, processed and manufacturedwithin 100 miles)" [1, p. 15].

Question 94
Which impact categories have been identified as most important for a LEED project to accomplish?
Correct Answer: A
Question 95
The cradle-to-cradle approach to sustainable materials evaluates
Correct Answer: A
Explanation The cradle-to-cradle approach to sustainable materials evaluates building materials from extraction to reuse, which means that the materials are considered as part of a continuous cycle of use and regeneration, rather than a linear process of consumption and disposal. The cradle-to-cradle approach aims to eliminate waste and pollution, conserve resources and energy, and create positive impacts for the environment and human health. The cradle-to-cradle approach is based on the principles of eco-effectiveness, which include designing products and systems that are safe and healthy for humans and nature, using renewable energy and clean water, celebrating diversity and creativity, and respecting social and environmental justice12. The cradle-to-cradle approach is also recognized and encouraged by LEED v4, which includes a credit for using products that have achieved Cradle to Cradle certification34.
