The project team should have selected LEED for Existing Buildings: Operations and Maintenance Rating System, as the operational and maintenance phase has begun for a newly constructed school in operation for one year and undergoing minor improvements. The LEED rating systems are designed to address the specific needs and characteristics of different types of buildings and projects. The project team should choose the most appropriate rating system for their project based on the scope, scale, and goals of the project. The LEED for Existing Buildings: Operations and Maintenance Rating System is intended for buildings that are already in use and want to improve their performance and sustainability through best practices in operation, maintenance, renovation, and occupant engagement1 . References: LEED v4 Green AssociateCandidate Handbook1, LEED v4 O+M Reference Guide

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]

Low cubicle partitions enhance the spread of daylight deeper into office spaces, improving natural lighting and reducing dependence on artificial lighting. This supports LEED credits under Indoor Environmental Quality, which aim to optimize daylight for better occupant health, productivity, and energy savings​​.

Acoustic Performance is a credit that aims to provide workspaces andclassrooms that promote occupants’ well-being, productivity, and communications through effective acoustic design1. This credit falls under the Indoor Environmental Quality category, which addresses the quality of the indoor environment as it relates to the health andcomfort of building occupants2. The Indoor Environmental Quality category has different credits for different LEED rating systems, such as LEED BD+C, LEED ID+C, LEED O+M, and LEED ND3. Acoustic Performance is one of the credits that is available for some of these rating systems, such as LEED BD+C: Schools, LEED ID+C: Commercial Interiors, and LEED O+M: Existing Buildings4.

Smart growth principles aim to create livable, walkable, and sustainable communities that reduce sprawl, preserve natural resources, and enhance quality of life. One of the principles is to foster distinctive, attractive communities with a strong sense of place by mixing land uses, providing a range of housing opportunities and choices, creating walkable neighborhoods, and encouraging community and stakeholder collaboration in development decisions. The project that protects open space and farmland by building housing and offering transportation choices near jobs, shops and schools exemplifies this principle. References: LEED v4 Green Associate Candidate Handbook, Smart Growth Principles

An integrative process is a collaborative approach that involves all project stakeholders in the design and decision-making process from the beginning to the end of a project. It aims to optimize the performance, environmental, social, and economic outcomes of a project by considering the interrelationships and synergies between various building and site systems. By identifying overlapping relationships, services and redundancies among systems, an integrative process can result in increased performance and reduced costs, as it can create more efficient, effective, and innovative solutions that meet the project goals and requirements. For example, an integrative process can help to reduce the energy demand of a building by integrating passive design strategies, such as building orientation, envelope design, daylighting, natural ventilation, and shading, which can also improve the indoor environmental quality and occupant comfort. An integrative process can also help to reduce the material and water consumption of a project by reusing existing resources, selecting durable and low-impact materials, and implementing water-efficient fixtures and systems, which can also reduce the waste generation and environmental impact of the project

The Montreal Protocol is an international treaty that aims to protect the ozone layer by phasing out the production and consumption of ozone-depleting substances (ODS). ODS are chemicals that contain chlorine or bromine, which can destroy the ozone molecules in the stratosphere. CFCs, or chlorofluorocarbons, are a group of ODS that were widely used in refrigeration, air conditioning, aerosols, and solvents. The Montreal Protocol banned the production of CFCs in 201012. Freon is a trade name for some CFCs and HCFCs, or hydrochlorofluorocarbons, which are also ODS but less harmful than CFCs. The Montreal Protocol also controls the production of HCFCs, which are being phased out gradually12. Ammonia is not an ODS and is not regulated by the Montreal Protocol1.

This is the correct order of the LEED certification process for most projects1. The first step is to register the project on LEED Online and pay the registration fee2. The second step is to prepare the application by collecting and uploading the required information and documents according to the chosen rating system and credits2. The third step is to submit the application and pay the certification fee2. The fourth step is to undergo the application review by a LEED accredited third party, which may request clarifications or corrections2. The final step is to receive the certification decision and the LEED plaque and certificate2.

Life-cycle cost analysts of a new construction includes consideration of

cost of purchasing window glazing

cost of adding accessible parking

cost of challenging a real estate tax assessment

cost of subsidizing the use of public transportation

Answer: A

Life-cycle cost analysis (LCCA) is a method for assessing the total cost of owning a facility or running a project. It considers all the costs associated with obtaining, owning, and disposing of an investment1. The cost of purchasing window glazing is one of the initial costs that affects the energy performance and thermal comfort of a building2. Therefore, it is included in the LCCA of a new construction.

The LEED credit weightings are based on the impact categories defined and established by the USGBC, which is the organization that developed and administers the LEED rating system. The impact categories are aligned with the USGBC’s mission and vision of transforming the built environment to enhance environmental and human health. The impact categories are also informed by the Environmental Protection Agency’s (EPA) Tools for the Reduction and Assessment of Chemical and Other Environmental Impacts (TRACI) methodology, which provides a framework for assessing environmental impacts across different categories. References: LEED Link: Impact categories, section “LEED v4 impact categories”; LEED v4 Impact Category and Point Allocation Process Overview, page 1; LEED Green Associate Candidate Handbook, page 14

Teams organize and work as part of an integrative process by working in small groups and as a whole with iterative processes. The integrative process is a method of design and construction that involves the collaboration and coordination of all project stakeholders from the beginning to achieve the project’s sustainability goals1. The integrative process requires teams to work in small groups, such as subcommittees or task forces, to focus on specific aspects of the project, such as energy, water, materials, indoor environmental quality, and site ecology2. The small groups then report back to the whole team and share their findings and recommendations, allowing for feedback and integration among different disciplines and systems2. The integrative process also requires teams to work with iterative processes, which means that they repeat and refine the design and analysis cycles until they reach the optimal solutions that meet the project’s performance targets3. The iterative processes enable teams to explore various scenarios, test assumptions, identify synergies and trade-offs, and evaluate the life-cycle impacts of their design decisions34.
