According to the U.S. Green Building Council, the indoor water use reduction credit requires engineers and architects to develop and implement strategies that use an average of 20% less water (indoors) than the standard calculated for the building.
Maximizing water efficiency can include:
- Reducing indoor consumption
- Reducing the load on municipal water supply and wastewater systems
- Maximizing indoor plumbing fixtures and fittings efficiency
In the commercial sector, Rexam’s Chicago Triangle Plaza office space achieved LEED Silver certification. Rexam’s space occupied the eighth floor out of a total of 14 floors in an existing non-certified building. The achievement came through the use of low flow plumbing fixtures and recycled / local materials and high efficient lighting design.
Careful fixture selection can be key to achieving LEED points for water use reduction. The fixtures governed by this credit include water closets, urinals, lavatory faucets, showers, and kitchen or break room sinks. Industry standards are very specific, including 1.6 gallon-per-flush-toilets, 1 gallon-per-flush urinals, and 2.5 gallon-per-minute faucets and showers.
With LEED engineering on staff, RTM is well equipped to help clients earn water use reduction credits and handle all green building needs.
