THE ARIZONA ARMY NATIONAL GUARD ECO BUILDING
MISSION Create a Functional and innovative office facility for the Arizona Army National Guard that Incorporates and exercises to the fullest extent feasible self-sustaining and pollution prevention principles. To challenge existing conventional building methodologies and supporting building systems through innovation and cost comparison of construction, operation and maintenance. To embrace technological advances that enable a modern office to function independently. To expand upon and champion gained successes throughout the life of the project.
While the ECO-Building has many facets it aims to educate through being a showcase and demonstration facility of the following: • Sustainability • Use of unwanted and waste materials • Partnerships • Solar energy in a highly energy efficient building • Full-cycle cost of construction and occupancy of a self-sustaining office building • Viable interfaces with the natural phenomenon to create a functional work environment
TIRE WALLS • The Walls are constructed of used light truck/SUV tires • Tires are filled with compacted earth • Each tire is essentially a rubber encased adobe block • Each block (tire) weighs approximately 300 pounds • There are approximately 5000 tires in the building
COOLING TUBES • The Tubes are primarily 60 inch concrete culvert pipe • There are two tubes, north and south, each is approximately 65 feet long. • The tubes are interconnected on the east side of the building. • The original intent was to attempt passive cooling using water or thermal mass. • There is now a heat pump supplying cooling and heating.
Central Courtyard As the exterior walls are constructed of solid earth and tires the concept of the interior courtyard was to allow ambient light in to the building. Keeping with the use of recycled material: the windows were removed from buildings at Ft. Huachuca that were to be demolished. The courtyard will have plants and be used as a break area, weather permitting
THE “GECKO” The Arizona Army National Guard, Environmental Office has adopted the Gecko as its mascot, the logo appears on shirts, cups and our building.
Interior Walls • All earth colored interior walls are tires covered with adobe. • Being as adobe is soft, acrylic was added to the mix to harden the surface, no dust created by the adobe walls. • The white walls are conventional construction with dry wall covering. • All paints used were low VOC.
The Roof • Is designed to collect rain water for storage and use in the rest rooms • Is conventional wood truss covered with plywood. • The roof itself is Standing Seam Metal
Electrical The building internal power is provided by renewable energy: • Approximately 11 kw of solar, including the “Thin Film Amorphous Silicone” panels applied to the roof • Seven solar trackers 5 with 8 Panels and 2 with 10 panels • Two wind generators, generating 400 w each
Insulation • The Building is highly insulated: • Beginning with the roof, Immediately under the roof is a Mylar Radiant Heat Barrier • Above the ceiling is approximately 18 inches of blown in cellulose with a cover of Mylar chip radiant barrier • The exterior walls average about 20 feet thick, using Thermal Mass to control heat • The entrances and Courtyard walls have spun glass insulation
Ambient Lighting • Light is brought in through various means: • Windows in the courtyard walls • Sky Lights • Solar Tube Sky Lights • Active Daylighting Systems (passive tarcking of the sun)
Cisterns • As stated earlier the roof is designed to collect rain water for later use. • The roof of this building will on an average year collect approximately 28,000 gallons of water, the 4 cisterns each hold 10,000 Gallons • This water is to be used in the rest rooms • For the toilet • For hand washing • But not for drinking
