The actual diversion rate is calculated by dividing the total weight of the diverted waste by the total weight of the generated waste. In this case, the project generated 2,000 lbs. ofsteel, 900 lbs. of carpet, 1,100 lbs. of wood, and 1,500 lbs. of wallboard, making a total of 5,500 lbs. of waste. The project diverted 1,800 lbs. of steel, 900 lbs. of carpet, 1,000 lbs. of wood, and 250 lbs. of wallboard, making a total of 3,950 lbs. of waste. Therefore, the actual diversion rate achieved is approximately 71.8%.

The Indoor Environmental Quality Prerequisite, Green Cleaning Policy, requires a plan for hazardous spill cleanup. This prerequisite focuses on reducing the exposure of building occupants and maintenance personnel to potentially hazardous chemical, biological, and particulate contaminants, which adversely affect air quality, human health, building finishes, building systems, and the environment. A well-defined spill cleanup plan is crucial for maintaining a safe and healthy indoor environment.References:LEED AP Operations + Maintenance Reference Guide, Indoor Environmental Quality section.

When the building type is not covered by the ENERGY STAR® rating tool, the energy baseline for Minimum Energy Performance can be determined using historical energy consumption data or a calibrated energy simulation. This approach allows for a tailored assessment of the building’s energy use that is specific to its actual performance.

The view factor is the percentage of the floor area that has a direct line of sight to the perimeter vision glazing. According to the LEED Reference Guide for Building Operations and Maintenance, the view factor for the diagram below is 2, which means that 75% or more of the floor area has a direct line of sight to the perimeter vision glazing.
