Minimal hardscape and permeable surfaces allow water to infiltrate, reducing rainwater runoff and supporting sustainable stormwater management strategies. These practices align with LEED Sustainable Sites goals​​.

Rainwater Management is a credit that aims to reduce runoff, improve water quality, and restore natural hydrology1. It is part of the Sustainable Sites category, which addresses the environmental impacts of the site selection, design, and construction23.

The Energy Policy Act of 1992 (EPAct of 1992) is a United States government act that set goals, createdmandates, and amended utility laws to increase clean energy use and improve overall energy efficiency in the United States1. The EPAct of 1992 is a baseline standard for the Energyand Atmosphere prerequisite category in LEED v4, which aims to reduce the environmental and economic impacts of excessive energy use and promote the use of renewable and alternative energy sources2. The EPAct of 1992 establishes the minimum energy performancerequirements for buildings, such as lighting power density, HVAC efficiency, and water heating efficiency3. The EPAct of 1992 also provides tax incentives and grants for energy conservationand renewable energy projects1. The EPAct of 1992 was amended by the Energy Policy Act of 2005, which updated some of the provisions and standards of the original act4.

Rainwater storage cisterns are components of a collected rainwater irrigation system that are most likely to make it cost prohibitive over a conventional system in a large site that has a short, intense rainy season and a long, dry season. A collected rainwater irrigation system is a system that collects, stores, and distributes rainwater for irrigation purposes. Rainwater storage cisterns are containers that store the collected rainwater until it is needed for irrigation. In a large site that has a short, intense rainy season and a long, dry season, the rainwater storage cisterns would need to be very large and durable to capture and store enough rainwater for the dry season. This would increase the initial cost and maintenance cost of the system compared to a conventional system that uses potable water or groundwater for irrigation1 . References: LEED v4 Green Associate Candidate Handbook1, EPA’s Rainwater Harvesting

Regenerative design is a type of design that goes beyond sustainability and aims to restore or enhance the natural systems that support life. Regenerative design projects not only minimize their environmental impact, but also contribute positively to the environment and society. An example of regenerative design is a building that generates electricity from renewable sources, such as solar panels or wind turbines, and sends the excess electricity to the grid, thereby reducing greenhouse gas emissions and supporting the transition to a clean energy economy.

Sustainable forestry is the practice of managing forest resources in a way that meets the current and future needs of humans forforest products, while also conserving and enhancing the ecological, social, and economic values of the forest and its surrounding landscape1. One of the key aspects of sustainable forestry is to maintain the biodiversity of the forest, which refers to the variety and abundance of living organisms, such as plants, animals, fungi, and microorganisms, and their interactions within the forest ecosystem2. Biodiversity is important for the health and resilience of the forest, as it provides essential ecosystem services, such as carbon sequestration, water purification, soil formation, nutrient cycling, pollination, pest control, and climate regulation23. Biodiversity also supports the livelihoods, cultures, and well-being of forest-dependent communities and indigenous peoples23.

An office without transit access can substantially reduce its transportation impact if workers are able to walk from the office to basic services. Transportation impact is the effect of transportation activities on the environment, society, and economy. Transportation impact can include greenhouse gas emissions, air pollution, noise pollution, energy consumption, land use, traffic congestion, infrastructure costs, and public health. Walking is a form of alternative transportation that can reduce transportation impact by using less energy, emitting less pollutants, occupying less space, and improving physical activity and well-being. If workers are able to walk from the office to basic services, such as retail, restaurants, banks, or post offices, they can reduce their vehicle miles traveled, fuel consumption, and parking demand1 . References: LEED v4 Green Associate Candidate Handbook1, EPA’s Transportation and Climate Change

The scope of the LEED impact category component Protect Human Health from Direct Exposure to Negative Health Impacts is building occupants and design and construction crew during the construction phase and use phase of the building cycle, within the project boundary and its immediate surroundings. This component aims to reduce the exposure of people to harmful substances or conditions that may affect their health and well-being. This includes indoor air quality, thermal comfort, lighting quality, noise levels, water quality, and safety hazards. The component covers both the construction phase and the use phase of the building cycle, as both stages can pose potential health risks to people involved or affected by the project. The component also considers both the project boundary and its immediate surroundings, as some health impacts may extend beyond the site itself. References: LEED v4 BD+C Reference Guide, Introduction, page 9

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

Retrofitting cooling towers to use non-potable water is the best answer because cooling towers are major process water users in many large commercial facilities. LEED Water Efficiency addresses process water through strategies such as cooling tower water management, non-potable water use, and monitoring to reduce potable water demand. Treated rainwater may be useful for some non-potable applications, but kitchen operations often require higher water quality and strict health-code compliance. ENERGY STAR washing machines can reduce appliance water use, but they may have a smaller impact than cooling tower improvements in a large commercial facility. Increasing once-through cooling is incorrect because it wastes significant amounts of potable water. Effective process-water reduction helps conserve municipal water supplies and reduce environmental strain.
