The Energy and Atmosphere (EA) category addresses the energy performance, efficiency, and renewable sources of buildings. One of the credits in this category is EA Credit: Enhanced Refrigerant Management, which aims to reduce the emissions of ozone-depleting substances and greenhouse gases from refrigeration and air-conditioning equipment. Refrigerants are substances that are used to transfer heat in cooling systems. Some refrigerants have high global warming potential (GWP) and ozone depletion potential (ODP), which means they can contribute to climate change and damage the ozone layer if they leak or are improperly disposed of. Enhanced refrigerant management involves selecting refrigerants with low GWP and ODP, minimizing refrigerant charge size, and preventing or detecting leaks12.

Explanation
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].

LEED rating systems are grouped under five broad categories, according to their construction types1. Each category has different adaptations for specific project types and scopes. LEED Operations & Maintenance (O+M) addresses existing buildings that are undergoing improvement work or little to no construction2. Schools are one of the adaptations under this category3. LEED Interior Design and Construction (ID+C) addresses complete interior fit-out projects2. Data Centers are one of the adaptations under this category3. LEED Building Design and Construction (BD+C) addresses new construction or major renovations2. Existing Buildings are not an adaptation under this category, but rather under O+M3. LEED Neighborhood Development (ND) addresses new land development projects or redevelopment projects containing residential uses, nonresidential uses, or a mix2. Warehouses and Distribution are not an adaptation under this category, but rather under BD+C3.

LEED Rating Systems Overview

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 . Reference: LEED v4 Green Associate Candidate Handbook1, EPA's Energy Efficiency

Explanation
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
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.
