LEED Fact Sheet

Aluminum sheet & Plate for the Building & Construction market

(LEED is ‘Leadership in Energy & Environmental Design’)
The LEED Green Building Rating system, as promulgated by the U.S. Green Building Council, aims to improve occupant well-being, environmental performance and economic returns of buildings using established and innovative practices, standards and technologies.

RECYCLED CONTENT

A survey of aluminum producers in late 2003 indicated that the total recycled content of domestically produced, flat rolled products for the building and construction market was approximately 80- 85%. A subsequent survey of the producers indicated that on average, approximately half of the recycled content (or 40- 42% of the total content) is from post consumer sources. While these numbers represent the industry average, higher post-consumer and total recycled content material may be available from individual producers. For information on the LEED program and to find out how you can earn credit for the recycled content of your aluminum products go to:

RECYCLABILITY

Not only does the aluminum used in the building and construction industry contain a high percentage of both post-consumer and post-industrial recycled content, at the end of its long, useful life in your building application it is 100% recyclable. Aluminum building components can be repeatedly recycled back into similar products with no loss of quality, and aluminum in its various forms provides the most valuable component for most municipal efforts.

To produce aluminum from recycled material requires only 5% of the energy required to produce aluminum from bauxite ore, and every ton of recycled aluminum saves 4 tons of bauxite. Additionally, using recycled aluminum instead of raw materials reduces air pollution generates such as CO2, Sox, and Nox by 95% and water pollution by 97%.

U.S. GREEN BUILDING COUNCIL- LEED for homes program

Water Efficiency: Credit #1 water Reuse- Maximum points: 2

    1. Design and install of rainwater harvesting system which includes the collection of surface and surface and roof run-off for irrigation uses (1 point).
    2. Design and install gray water re-use system, with minimum of dedicated clothes washer with 2 inch drain directed to subterranean drain field for landscape irrigation. (1 point)

USGBC Rationale: 50% of potable water use in a home may be for maintenance of lawns and gardens. This credit promotes sustainable design and the re-use of indoor waste water and rainwater to help meet landscape water demands. The synergy between durability, energy efficiency, and indoor air quality are inextricably linked in high performance homes. Moisture management becomes more critical as energy management reduces the buildings overall drying potential. “Moisture can be a major cause of indoor environmental problems (e.g.,mold). The point value of this credit therefore reflects the related indoor environmental benefits of improved water management at the foundation, exterior walls, and roof. Water management of the property (i.e., both lot and structure) is a combination of surface and ground water management, with the dual goals of protecting the structure from water as well as keeping as much water as possible, the site and landscape should be designed with these goals in mind. The durability plan is intended to prevent damage to the home by water- both surface and ground – that cannot be effectively managed at the site level, as well as to protect the structure from other damage functions.
