- Reduce the total ownership cost of facilities
- Improve energy efficiency and water conservation
- Provide safe, healthy, and productive built environments
- Promote sustainable environmental stewardship
Water Consumption Intensity
Total water consumption per square foot of building space (e.g., kgal/sq-ft)
WaterSense, a partnership program of the U.S. Environmental Protection Agency (EPA), seeks to help consumers make smart water choices that save money and maintain high environmental standards without compromising performance. Independent, third-party licensed certifying bodies certify that products meet EPA criteria for water-efficiency and performance by following testing and certification protocols specific to each product category. Products and services that have earned the WaterSense label have been certified to be at least 20% more efficient without sacrificing performance.
