USGBC LEED-Green-Associate - LEED Green Associate GAFRE Exam (LEED GA)

The Full Time Equivalent (FTE) occupancy of a project is a measure of how many people occupy a building or space on a regular basis. The FTE occupancy is calculated by dividing the total number of hours worked by all occupants in a week by the standard weekly hours for one FTE occupant. Thestandard weekly hours for one FTE occupant is typically 40 hours per week1 . For this project, the FTE occupancy is calculated as follows:

16 employees x 4 hours/day x 5 days/week = 320 hours/week 20 employees x 6 hours/day x 5 days/week = 600 hours/week 10 employees x 8 hours/day x 5 days/week = 400 hours/week Total hours/week = 1320 hours/week FTE occupancy = 1320 hours/week / 40hours/week = 33 Therefore, the FTE occupancy of the project is 33. References: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide

Sustainable landscape design aims to create landscapes that are in harmony with the local environment, conserve natural resources, and provide ecological benefits. One of the outcomes of sustainable landscape design is restoring and regenerating habitat for native plants and animals, which enhances biodiversity and ecosystem services.

Should non-design team stakeholders be included in design charrettes?

No, because it may increase legal liability

Yes, because it may help to reduce future litigation

No, because they lack the expertise to contribute design ideas

Yes, because they enhance understanding of community concerns

Answer: D

Design charrettes are collaborative sessions where stakeholders brainstorm and generate design solutions for a project. Non-design team stakeholders, such as community members, clients, users, and regulators, can provide valuable input and feedback on the project goals, needs, challenges, and opportunities. Including them in design charrettes can help to create more sustainable, inclusive, and responsive design outcomes that meet the expectations and requirements of all parties involved. References: LEED Green Associate Candidate Handbook, page 14; LEED Green Associate | U.S. Green Building Council, section “LEED v4 Rating Systems”

LEED promotes compact, transit-rich locations:

“Locating a project in an area that supports walking, biking, and mass transit... will result in lower GHG emissions from reduced car travel.”

Urban centers offer the best access to alternative transport and reduce reliance on fossil fuels.

Renewable Energy Certificates (RECs) are tradable, non-tangible energy commodities that represent the environmental attributes of one megawatt-hour of electricity generated from renewable sources, such as wind, solar, hydro, or biomass1. RECs can be purchased by anyone, regardless of their location or utility provider, to support the development of renewable energy and reduce their carbon footprint2. RECs can also help projects earn points for the LEED v4 Innovation credit for Green Power and Carbon Offsets,which requires the purchase of at least 50% of the total building energy use from renewable sources or offsets for a minimum of five years3.

Installing a solar photovoltaic system can significantly reduce greenhouse gas emissions from a building. Solar panels generate electricity from sunlight, a renewable resource, instead of burning fossil fuels that release carbon dioxide and other greenhouse gases. While solar panels do require an upfront investment, they can also result in lower energy bills over time. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

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

A charrette is a collaborative workshop that brings together various stakeholders and experts to address a particular design issue, such as sustainability, security, or accessibility. A charrette should take place at the beginning of the project, when the project goals, scope, and budget are being defined, and when the most impact can be made with the least cost. A charrette can help establish a shared vision, identify potential challenges and opportunities, and generate innovative and integrated solutions.

 A Handbook for Planning and Conducting Charrettes for High-Performance Projects, page 1-2; LEED v4 Green Associate Candidate Handbook, page 12.

In the context of a LEED project, the charrette is a meeting of stakeholders, project team members and others to establish project objectives. The charrette is a collaborative and participatory process that involves brainstorming, discussing, and generating ideas and solutions for the project’s sustainability goals, design strategies, performance targets, and evaluation methods. The charrette is usually held at the early stages of the project to ensure alignment and integration among all parties involved. The LEED Green Associate Candidate Handbook states that one of the steps in the integrative process is to “conduct a preliminary LEED assessment with key project team members, including owner” [1, p. 12]. References: LEED Green Associate Candidate Handbook, [Charrette | Whole Building Design Guide]

Scope 1 greenhouse gas emissions are direct emissions from sources that are owned or controlled by the organization. On-site landfills are an example of a source of Scope 1 emissions, as they release methane and carbon dioxide from the decomposition of organic waste12.

Business travel, purchased electricity, and employee commuting are examples of sources of Scope 2 or Scope 3 emissions, which are indirect emissions from sources that are not owned or controlled by the organization. Business travel and employee commuting are Scope 3 emissions, as they occur from the activities of the organization’s value chain, such as suppliers and customers12. Purchased electricity is a Scope 2 emission, as it occurs from the generation of electricity that the organization consumes
