Airwise Structure

Airwise Environmental Structureswww.airwisestructures.com “a perfect day, every day, guaranteed!” Bring the Outdoors “in” Defining “Green” Since 1971 … the only large free span structures that inherently support natural turf and vegetation. Agriculture was our first application Produces efficient, healthy, thriving environments. Developed by Goodyear Tire & Rubber The pressure of air inside the building is relatively high and can not be easily or affordably exchanged or freshened. Assume a pressure of 7. Plants will not survive in such an environment. high with a Radius of ~106.  Stress in lbs/ft = pressure in lbs/ft2 x Radius of the Arc of the Sphere (cover) in ft 200 ft wide structure will be ~70 ft. = stress on the cover of 798 lbs/ft.5 lbs per sq. ft. requiring supplemental lighting for most of the day as well as night.4 ft. stale air to accumulate.  Typical Air Supported Structure with Air Pressure Retained by the Cover       To withstand such pressure. The Formula for stress in the surface is. A small fraction of natural light is let into the structure. nor do livestock or people! .4 ft. x 106. The maximum possible spans are ~ 400 ft. because of the added stress on the cover and cables. heavy. composite material.Where’s the Difference?   The stress applied to the cover material determines how heavy that material must be and the pressure under which the air must be retained. usually reinforced with webbing of some type of polymer is used. Lack of ventilation allows mold and mildew to grow. . weather proof environment The stress on the cover does not change regardless of the width of the building.Here’s the Difference!  Remember: The Formula for stress in the surface is. long x . Extra load can be picked up by using larger or closer spaced steel cables. or 30 lbs. allowing for the use of much thinner fabric in the cover. When the structure is inflated.  Airwise Environmental Structures        Plants. this excess material forms a mini-arc 4 ft. It is secured to and within the seams in the fabric cover. This allows for fast and frequent air exchanges.5 lbs/ft 2 . high with a radius of 4 ft. As much as 90% of natural light is allowed into the interior. Assuming the same pressure in the previous example of 7. intervals the length of the structure. Almost all the load is transferred to the cables. Livestock and People thrive in a healthy. the calculated stress on the fabric is now 7.  Stress in lbs/ft = pressure in lbs/ft2 x Radius of the Arc of the Sphere (cover) in ft A galvanized steel cable is placed at 4 ft.5 lbs x the radius of the mini arc of 4 ft.5 ft. Operating pressure is much reduced so High Volume Low Pressure (HVLP) fans can be used to move air instead of Low Volume High Pressure blowers./ft. Between these cables is place 50” instead of 48” of material. Shadow-Free Interior Broadcast conditions day and night Creative Lighting Outdoor light is reflected “in” at night to create daytime conditions. . Light passes through the materials so that broadcast lighting is seen from the inside and outside. Pleasant and easy communication Fire retardant Mold resistant Self-cleaning Sound is not reflected off of our soft design cover . Sturdy engineering supports heavy loads …even stage lighting and solar panels Inside materials glisten in night lighting . .Natural Circulation = Fresh Air Air can be exchanged as often as once per minute! Moisture is kept under control for a clean and dry Air moves naturally from fans to vents mold resistant environment. making a unique and highly functional building. . The roof of this Frank Lloyd Wright castle is covered with our membrane to prevent water leaks.Close Quarter Designs Structural Integration Different designs can be created by combining traditional “brick & mortar” materials with our “soft structure” . Flexible Configurations This Airwise Structure does not touch any surrounding objects . 20.Cover can be deployed in hours on a prepared site We create a cover. sealed “out of sight” into the fabric.000 sq. cover ready for shipment The one piece cover includes the cables. This portable cover was deployed in 2 hours and inflated in 3 minutes. ft. folded accordion style. then rolled to a center on a single skid for easy handling and storage. . The one-piece cover is spread out and attached to the anchors 4.000 sq. The site is prepped while the cover is manufactured 3.1. with a total of six tools. . and packed into a 38’ trailer in less than 10 hours. ft. then disassembled by six people. The power is turned on and within 5 minutes the building is fully functional This 12. temporary building was deployed in 2 days. It arrives as a “Ready to Assemble” Kit 2. The One-Piece cover is deployed or replaced without disturbing any activity below. Allows periodic upgrade and replacement of cover materials at a fraction the cost of new building. An old cover is removed as another is deployed The crane happened to be on site and is not necessary to deploy or replace covers. .
