What is the maximum allowed flush volume for toilets according to LEED standards?

The maximum allowed flush volume for toilets according to LEED standards is 1.28 gallons per flush. This standard aligns with the intent of LEED to promote water efficiency and reduce overall water consumption in buildings. By specifying this limit, the LEED framework encourages the use of high-efficiency toilets, which can significantly contribute to reducing water usage in both residential and commercial settings.

LEED's focus on 1.28 gallons per flush supports the goal of sustainable building practices, as traditional toilets often use 1.6 gallons or more. This guideline not only helps in conserving water resources but also reduces operating costs associated with water usage. The adoption of such efficient toilet fixtures can lead to substantial savings over time, making it an essential aspect of water efficiency credits in LEED certification.
