Roof Insulation

Achieve a whole-roof R-value of 25 or greater  节水方案: Water Conservation and Use

The site is located in an arid region in the midst of a long-term drought. Water in this area is obtained from deep, low-producing wells. Due to the its remote location, the school needed its own water supply, and a water tower was included in the project.

Low-flow fixtures (using 0.5 gallons of water per minute) with motion sensors save a significant amount of water. The building is expected to use at least 30% less water than a comparable, conventionally designed building.

Since water use for any purpose is expensive, exterior use can be justified only for the establishment of drought-tolerant plants that require little water. The design team selected netleaf hackberry, rocky mountain juniper, valley cottonwood, and purple robe locust trees; fourwing saltbush and chamisa shrubs; beargrass and banana yucca succulents; and winecups groundcover. It is hoped that the natural landscaping will form a part of the educational curriculum and teach children about the ecology of the area.

After a period of temporary drip irrigation (a maximum of two years) all of these plants will be forced to depend on rainfall to survive. At that point, all visible emitters from the drip irrigation system and all control valves and controllers will be removed. The underground plastic piping will be abandoned.

Runoff from the building is channeled through carefully sculpted rock arroyos to maximize onsite infiltration. Native plants will be allowed to grow along these areas. As much site runoff as possible is channeled to low-lying areas to maximize onsite infiltration.

材料选择: Recycled materials were used wherever possible in the building construction. The concrete masonry units were manufactured with flyash replacing about 18% of the portland cement; recycled steel scrap provided more than 90% of building's structural steel; and the gypsum core of the wallboard products was comprised of about 8% recycled materials. In total, 6.9% of the building materials, by cost, were recycled, as per the LEED v2 calculations.

Materials manufactured regionally were also preferred, in order to minimize the transportation costs associated with the building. Just over 47% of the total value of the materials and products used were manufactured within a 500-mile radius of the building site, a region that includes Albuquerque, New Mexico; Phoenix and Tucson, Arizona; Salt Lake City, Utah; Colorado Springs, Colorado; and Lubbock and El Paso, Texas. Of those materials, at least 50% of the content was extracted within 500 miles of the site.

Designated recycling bins are located in key areas of the school, including the cafeteria, classrooms, copy areas, and workrooms. Products to be recycled include paper, glass, aluminum, and plastic. All recyclable materials are then placed in appropriate canisters in the recycling room or taken directly to larger receptacles adjacent to the loading dock at the service entry. All children are expected to participate in this program.
