LEED-Green-Associate Exam Dumps - USGBC Leadership in Energy and Environmental Design (LEED) Questions and Answers

An integrative design process is a collaborative and holistic approach that involves the project team and stakeholders from the early stages of the project to identify the project goals, analyze the site and climate conditions, explore multiple design options, and optimize the performance and cost-effectiveness of the project. By applying an integrative design process, a LEED project can achieve higherlevels of sustainability and efficiency, as well as reduce the risks of errors, delays, and change orders12. References: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide2

The protection and restoration of natural vegetation, wetland areas and bodies of water through building footprint consolidation helps to preserve open space and sensitive areas, which are important for maintaining biodiversity, ecosystem services, and human well-being. Building footprint consolidation refers to the strategy of minimizing the area of land that is occupied by a building and its associated infrastructure, such as roads, parking lots, and utilities. By reducing the building footprint, project teams can avoid or minimize the impacts of development on natural habitats, wetlands, and water bodies, which often provide critical functions such aswater quality improvement, flood control, wildlife habitat, and recreation. LEED v4.1 recognizes and rewards this strategy in the Sensitive Land Protection credit1, which aims to conserve existing natural areas and restore damaged areas to provide habitat and promote biodiversity2. References: LEED Link: Sensitive Land Protection, section “LEED v4.1 BD+C: Sensitive Land Protection”; Sensitive Land Protection | U.S. Green Building Council, section “Intent”

The Forest Stewardship Council (FSC) is an independent, non-governmental organization that promotes responsible management of the world’s forests. FSC sets standards for forest management that ensure environmental, social, and economic benefits for present and future generations. FSC also certifies forest products that meet its standards through a chain of custody system that tracks the origin and processing of the products. A wood product that is certified by FSC is guaranteed to be harvested from a well-managed source that protects biodiversity, respects indigenous rights, maintains forest productivity, and supports local communities1 . References: LEED v4 Green Associate Candidate Handbook1, FSC’s What We Do

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 manufactured within 100 miles)” [1, p. 15]. References: LEED Green Associate Candidate Handbook, [Environmentally Preferable Purchasing | U.S. Environmental Protection Agency]

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.

A minimum program requirement for LEED for New Construction and Major Renovations projects is to be a permanent building or space on existing land. This means that the project must be designed and constructed for a fixed location on land that is legally defined and has legal boundaries. The project cannot be a temporary structure, such as a trailer or a tent, or a movable structure, such as a boat or a vehicle. The LEED Green Associate Candidate Handbook states that this is one of the four minimum program requirements that apply to all LEED rating systems [1, p. 9]. References: LEED Green Associate Candidate Handbook, [Minimum Program Requirements | U.S. Green Building Council]

ASHRAE 189.1 is a standard that provides guidance for the design, construction, and operation of high-performance green buildings that comply with building codes and voluntary rating systems. The standard covers topics such as site sustainability, water efficiency, energy efficiency, indoor environmental quality, and the impact of materials and resources12. References: LEED v4 Green Associate Candidate Handbook1, ASHRAE’s Standard 189.12

According to the LeadingGreen Study Guide:

“WaterSense is an EPA-sponsored program that promotes and certifies water-efficient products, programs, and practices.”

TheEnvironmental Protection Agency (EPA)is the correct federal agency.

Designing buildings to shade each other can help reduce energy demand by decreasing cooling loads. By strategically positioning buildings on a site, it’s possible to use the buildings themselves to block solar heat gain, reducing the need for air conditioning. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

The result of proper design and operation of buildings and neighborhoods is an increase in energy efficiency. Energy efficiency is the ratio of useful output to energy input for a system or process. Energy efficiency can be improved by using less energy to perform the same function or by using renewable or low-impact energy sources. Energy efficiency can reduce greenhouse gas emissions, energy costs, and dependence on fossil fuels1 . References: LEED v4 Green Associate Candidate Handbook1, EPA’s Energy Efficiency
