The Green Infrastructure and Buildings Credit for Indoor Water Use Reduction rewards projects that implement water-saving technologies and fixtures, such as dual-flush toilets. Dual-flush toilets allow users to choose between a full flush or a reduced flush, which significantly reduces water consumption for toilet use. This strategy directly contributes to earning points under this credit by lowering the total indoor water usage in the project.
