As of 1996, the Montreal Protocol banned the production of chlorofluorocarbons (CFCs), a chemical compound known to have ozone-depleting potential. CFCs are synthetic substances that were widely used as refrigerants, propellants, solvents, and foam-blowing agents. CFCs have high ozone depletion potential (ODP), which means they can destroy the ozone layer that protects the Earth from harmful ultraviolet radiation. 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. The Montreal Protocol banned the production of CFCs in 1996 for developed countries and in 2010 for developing countries1 . References: LEED v4 Green Associate Candidate Handbook1, UNEP’s Montreal Protocol

 Flush out process is performed to remove volatile organic compounds (VOCs) from the indoor air after construction or renovation12. VOCs are chemicals that can evaporate at room temperature and cause health problems, such as headaches, nausea, and irritation3. Flush out process involves supplying 100% outdoor air to the building for a certain period of time or until a certain amount of air changes are achieved12.

An existing LEED certified building located on a college campus is eligible for LEED for Building Operations and Maintenance; Existing Buildings (LEED O+M: EB). This rating system applies to existing buildings that are undergoing improvement work or little to no construction. It focuses on measuring and improving the performance of building operations and maintenance practices in areas such as energy efficiency, water conservation, waste management, indoor environmental quality, transportation, and occupant satisfaction. To be eligible for LEED O+M: EB, a project must meet certain minimum program requirements (MPRs), such as having a reasonable site boundary, being in a permanent location on existing land, being fully operational and occupied for at least one year prior to certification application, and complying with environmental laws and regulations. References: LEED certification for existing buildings and spaces6; Maintaining certification7; LEED v4: Building Operations + Maintenance Guide4

Climate change is weighted the most in the LEED rating systems because it is considered the most urgent and significant environmental challenge facing humanity. Climate change is caused by the accumulation of greenhouse gases in the atmosphere, which trap heat and alter the global climate patterns. Climate change can have severe consequences for human health, biodiversity, water resources, food security, and social equity. LEED projects can help mitigate climate change by reducing greenhouse gas emissions from building operations and materials, as well as enhancing resilience and adaptation to climate impacts. The LEED impact categories and point allocation process assigns 35% of the total points to climate change. References: LEED v4 Impact Category and Point Allocation Process Overview2; LEED v4 BD+C Reference Guide, Introduction, page 9

Resource depletion is a major environmental concern related to energy use. The extraction and use of non-renewable energy resources (such as fossil fuels) can lead to their depletion over time. This is why strategies that reduce energy use or utilize renewable energy sources are important in green building practices. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

The USGBC member logo may be displayed by an organization that is a member of the USGBC. Membership in the USGBC is organizational, not individual, so the logo represents the organization’s commitment to sustainability and green building practices. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

Recycling is a strategy that can be used to reduce the amount of construction waste that is sent to landfills or incinerators. Recycling involves collecting, sorting, processing, and reusing or selling materials that would otherwise be discarded as waste. Recycling can save natural resources, reduce greenhouse gas emissions, create jobs, and lower disposal costs1 . References: LEED v4 Green Associate Candidate Handbook1, EPA’s Recycling Basics

Pre-consumer recycled content refers to waste material that is diverted from the waste stream during the manufacturing process. This can include scraps or trimmings that are collected and returned to the manufacturing process. It does not include rework, regrind, or scrap materials capable of being reclaimed within the same process that generated them. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources
