Water Efficiency 3.2 – Water Use Reduction – 30% Reduction
Credits WE 3.1 & WE 3.2 are the same except for the percent (%) reduction. If one completes the requirements and implementation for WE 3.2 – Water Use Reduction – 30%, they would also receive a point for WE 3.1. Thus, earning two points toward LEED accreditation for the project. The posts for WE 3.1 […]
