Compare the baseline and design case water use budgets to determine the water reduction percentage goals for the project. The LEED Online credit form has a built-in calculator to facilitate this calculation. Repeat this process until final selection of water fixtures and strategies have been made and the project’s water reduction goals are satisfied.
Select water-efficient fixtures and strategies. Gather information on applicable fixtures including manufacturer, model number, and flush or flow rates.
Determine user groups for the various fixtures as not all occupants may be using all the fixtures; for example, employee restrooms and customer toilets in a retail store will have different use patterns.
The mechanical engineer, architect and acoustics consultant collaborate to design compliant wall, door and window assemblies; mechanical systems; and delivery systems that will meet the LEED prerequisite requirements.
The architect or acoustics consultant calculates the volume of all classrooms and core learning spaces to determine the appropriate compliance path for RT.
Determine the numbers and types of occupants in the building. The water use calculation is based on occupant use and the number of full-time equivalent (
Establish goals for water use reduction and include these goals in the Owner’s Project Requirements (OPR) for EAp1: Fundamental Commissioning. Consider aiming higher than a 20% reduction.
