This option applies to projects that renovate an existing building that meets the definition of abandoned or blighted, and use new materials for at least 50% of the surface area.The project meets these criteria, as the warehouse is an existing building that is presumably abandoned or blighted, and the new construction will use new materials for 40% of the interior and some of the exterior.Reference: LEED v4: Building Design + Construction Guide, Materials and Resources Credit, Building Life-Cycle Impact Reduction, Option 4: Renovation of Abandoned or Blighted Building

. Makeup water meters, conductivity controllers and overflow alarms

According to the Water Efficiency Prerequisite for Indoor Water Use Reduction, cooling towers and evaporative condensers must be equipped with makeup water meters, conductivity controllers and overflow alarms to reduce water consumption and prevent water waste. These devices help monitor and control the water quality, flow rate and level of the cooling system, and alert the operators of any malfunctions or leaks.

For the Materials and Resources (MR) Credit: Building Product Disclosure and Optimization - Environmental Product Declarations (EPDs), products must demonstrate a reduction below the industry average in at least three categories (B) to qualify for product optimization. Type III EPDs provide verified environmental impact data across multiple categories (e.g., global warming potential, ozone depletion). LEED encourages using products that have a lower impact than the industry standard, specifically in three or more environmental impact categories, to promote sustainable material selection.

A charrette is a collaborative design process that involves multiple stakeholders, such as the owner, the design team, the community, and the users. By including the public in a charrette for a new school before the pre-design phase, potential partnerships with the community can be revealed. For example, the school might share facilities or resources with a nearby library, park, or community center. This can enhance the social and environmental benefits of the project, as well as reduce costs and increase efficiency.

The intent of the Water Efficiency Prerequisite, Outdoor Water Use Reduction is to reduce outdoor water consumption by either eliminating the need for irrigation or reducing the irrigation demand by at least 30% from the baseline. This prerequisite requires project teams to evaluate the project's outdoor water budget and irrigation water demand using the EPA WaterSense Water Budget Tool or a local equivalent. This will help project teams to estimate and optimize water use in landscape designs by selecting appropriate plant species and irrigation system efficiency.
