Social responsibility is one of the factors that contribute to the triple bottom line. The triple bottom line is a framework that measures the performance of an organization or a project based on three dimensions: environmental, social, and economic. Social responsibility refers to the ethical obligation of an organization or a project to consider the impacts of its decisions and actions on society and stakeholders, such as employees, customers, communities, and future generations. The other options are not factors that contribute to the triple bottom line. Global security is a broad concept that encompasses various aspects of international relations, such as peace, human rights, justice, and cooperation. Project balance sheet is a financial statement that summarizes the assets, liabilities, and equity of a project at a given point in time. Green metrics and verification are tools and methods that quantify and validate the environmental performance of a project or a product.

The term "LEED certified building" is the correct usage according to the U.S. Green Building Council (USGBC). This term indicates that a building has met the standards set by the LEED rating system and has been officially certified by the USGBC.

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.

An externality is a consequence of an economic activity that affects other parties who are not directly involved in the activity. Externalities can be positive or negative, depending on whether they create benefits or costs for others. When a developer builds a new shopping center in a rural area, one externality might be an increase in traffic on adjacent roads. This is a negative externality because it imposes costs on other road users who are not part of the development project, such as increased travel time, fuel consumption, air pollution, noise pollution, and accident risk13.

Daylighting is a strategy that uses natural light to illuminate the interior spaces of a building, reducing the need for artificial lighting and improving the visual comfort and well-being of the occupants. One of the strategies that can help improve daylighting in an office building is to locate private offices toward the building core and organize cubicles at the perimeter, so that more people can benefit from the access to windows and views. This can also increase the daylight penetration depth and reduce glare and contrast12. Reference: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide2
