Water efficiency means minimal use of potable water from the municipal system. This efficiency provides a dual cost savings by reducing the volume of water used and sewage treated and the power used to transport and heat the water. For more detailed information on LEED requirements, please refer to the USGBC’s LEED Rating System.

1. Potable water use reduction – Minimize potable water use for landscaping
