The construction industry now has more insight to many environmentally sound construction planning. It now has leadership in certification of many of the construction practices of today, and importantly from the conceptual design stage to through completion. This “Leadership in Energy and Environmental Design” (LEED) is headed by U.S. Green Building Council; which encourages and accelerates global adoption of sustainable green building and development practices through the creation and implementation of universally understood and accepted tools and performance criteria. They offer courses, training, and testing to insure certification.
Although Energy savings seems to be their main interest, they do have a Water Efficiency credit category to encourage smarter use of water, inside and out. Water reduction is typically achieved through more efficient appliances, fixtures and fittings inside and water-wise landscaping outside.
LEED is a voluntary certification program that can be applied to any building type and any building life-cycle phase. It promotes whole-building approaches to sustainability. (More later)
