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

Drip irrigation is a method of watering plants that delivers water directly to the roots through a network of pipes, tubes, valves, and emitters. Drip irrigation is not a plumbingfixture, but a landscaping technique that can reduce outdoor water use by minimizing evaporation, runoff, and overspray12.

Plumbing fixtures are devices that provide water for various purposes, such as washing, bathing, cooking, or flushing. Plumbing fixtures include urinals, showerheads, kitchen faucets, and other types of faucets, toilets, bidets, and sinks. Plumbing fixtures are subject to indoor water use reduction strategies in LEED certification, such as installing low-flow or high-efficiency models, using automatic sensors or timers, or implementing water reuse systems34.

The Energy and Atmosphere Credit in LEED encompasses building loads, energy performance management, and environmental quality (EQ). Building loads refer to the amount of energy consumed by a building’s systems, such as heating, cooling, lighting, and equipment. Energy performance management involves strategies to reduce energy consumption and improve efficiency. Environmental quality refers to the conditions inside the building, including air quality, thermal comfort, and access to daylight and views. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

The Integrative Process is most effective during the early design stage of a project. This is when key decisions about the project are being made that can have a significant impact on its sustainability performance. By considering sustainability objectives from the outset, teams can identify opportunities for synergies and cost savings that may not be apparent later in the project. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

Submetering systems are devices that measure the water consumption of specific building components, such as cooling towers, irrigation systems, process water systems, or tenant spaces. They allow the facility operator to monitor and optimize the water use of different systems and identify any leaks or inefficiencies12. Submetering systems are also required for some LEED credits, such as Water Metering and Cooling Tower Water Use3.

receptacle load is the electrical load that is connected to the building’s electrical system through receptacles (also known as outlets or sockets). Receptacle load includes both regulated and non-regulated loads, such as computers, printers, monitors, lamps, refrigerators, microwaves, coffee makers, etc. Receptacle load does not include hard-wiredequipment, such as lighting fixtures, HVAC systems, or elevators12.

Receptacle load is one of the major components of plug and process loads (PPLs), which consume about 47% of primary energy in U.S. commercial buildings2. Reducing receptacle load can help improve building energy efficiency and achieve LEED certification. One of the strategies to reduce receptacle load is to use automatic receptacle controls, which are devices that turn off or reduce power to receptacles when they are not in use. Automatic receptacle controls are required by ANSI/ASHRAE/IES Standard 90.1-2019: Energy Standard for Buildings Except Low-Rise Residential Buildings, as well as NIH DRM 10.5.313.

Light-colored paving and cool roofs refer to materials with higher emissivity and higher albedo. Emissivity is the ability of a material to emit heat that it absorbs, while albedo is a measure of how much light that hits a surface is reflected without being absorbed. Materials with high emissivity can help reduce heat islands by releasing more of the heat they absorb, while those with high albedo can reflect more sunlight and thus stay cooler. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

The statement that is the U.S. Green Building Council (USGBC) vision is: Buildings and communities will regenerate and sustain the health and vitality of all life within a generation. USGBC is a non-profit organization that promotes sustainability in the building industry through its LEED rating system, education programs, advocacy initiatives, and research projects. USGBC’s vision reflects its commitment to transformingthe built environment into one that supports human health, environmental quality, social equity, and economic prosperity1 . References: LEED v4 Green Associate Candidate Handbook1, USGBC’s Vision

In LEED v4 BD+C, the Rainwater Management credit is part of the Sustainable Sites (SS) category. This credit aims to reduce the volume and improve the quality of stormwater runoff by mimicking the natural hydrology of the site.

“The intent of this credit is to reduce runoff volume and improve water quality by replicating natural hydrology and water balance of the site.”

– LEED v4 BD+C Reference Guide, SS Credit: Rainwater Management

Key components include:

Managing rainfall on site using green infrastructure,

Promoting infiltration, evapotranspiration, and reuse,

Addressing both quantity and quality of runoff.

This credit does not fall under:

Water Efficiency (A) – which focuses on reducing potable water use indoors/outdoors.

Location and Transportation (C) – which addresses site accessibility and connectivity.

Energy and Atmosphere (D) – which deals with building energy systems.

Correct answer: B. Sustainable Sites

According to the LeadingGreen Guide:

“Individual controls for lighting have a significant effect on occupants’ comfort. Meeting the unique needs of each occupant can be accomplished through effective design of lighting controls…”

LEED credits under EQc6 emphasize providing lighting comfort and energy savings through such controls.

An office without transit access can substantially reduce its transportation impact if workers are able to walk from the office to basic services. Transportation impact is the effect of transportation activities on the environment, society, and economy. Transportation impact can include greenhouse gas emissions, air pollution, noise pollution, energy consumption, land use, traffic congestion, infrastructure costs, and public health. Walking is a form of alternative transportation that can reduce transportation impact by using less energy, emitting less pollutants, occupying less space, and improving physical activity and well-being. If workers are able to walk from the office to basic services, such as retail, restaurants, banks, or post offices, they can reduce their vehicle miles traveled, fuel consumption, and parking demand1 . References: LEED v4 Green Associate Candidate Handbook1, EPA’s Transportation and Climate Change
