Which prerequisite applies to projects under the Energy Star requirements?

The prerequisite that applies to projects under the Energy Star requirements is related to water use reduction. Specifically, the Indoor Water Use Reduction prerequisite sets specific performance goals aimed at reducing the use of potable water within buildings. This is essential as buildings account for a significant proportion of water consumption, and improving water efficiency is a critical component of sustainable building practices.

The Energy Star program emphasizes energy efficiency, which can be closely linked to other resource efficiency measures, such as water conservation. While projects pursuing Energy Star certification benefit from a holistic approach to sustainability, establishing baseline reductions in indoor water use aligns with the overarching goals of resource efficiency.

Projects must meet specific criteria outlined in the prerequisite, which often includes setting water use reduction targets that must be achieved to support broader sustainability objectives. Thus, this prerequisite directly complements the energy efficiency focus of the Energy Star program.
