Light-colored paving and cool roofs refer to materials with higher emissivity and higher albedo. Emissivity is the ability of a material to emit heat that it absorbs, while albedo is a measure of how much light that hits a surface is reflected without being absorbed. Materials with high emissivity can help reduce heat islands by releasing more of the heat they absorb, while those with high albedo can reflect more sunlight and thus stay cooler.

Low-emitting materials, including partitions, are intended to:
"...reduce concentrations of chemical contaminants that can damage air quality, human health, productivity, and the environment." VOCs are a major indoor air contaminant addressed under the Indoor Environmental Quality category.

The Forest Stewardship Council (FSC) is a third-party verification organization that certifies forest products that are sourced from responsibly managed forests that meet environmental, social, and economic standards12. FSC-certified wood products are considered environmentally preferable products under the LEED v4 Materials and Resources category, as they reduce the negative impacts of deforestation, habitat loss, and biodiversity loss34.

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 .

The LEED minimum program requirements state that for LEED BD+C and LEED O+M rating systems, the LEED project must include a minimum of 1000 ft2 (93 m2) of gross floor area1.
