6 Tinker buildings being ventilated Published April 2, 2013 By Mike W. Ray Tinker Public Affairs TINKER AIR FORCE BASE, Okla. -- Ventilation improvements are being made to several buildings on base. Cross-flow ventilation louvers have been or will be installed in the walls of Defense Logistics Agency warehouses -- Bldgs. 412, 506, 510 and 1146, as well as Bldgs. 469 and 3001A -- and exhaust fans will be installed on the roofs of all but one of those buildings. Since Bldg. 1146 is unoccupied, only the louvers will be installed there, Project Superintendent Tom Duncan explained. The openings are intended to enable fresh air to enter the storage buildings, especially during Oklahoma's sweltering summers, Mr. Duncan said. The louvers and the fans will exchange the air in the buildings every 15 minutes, he said. Control dampers will be installed inside the warehouses to open the louvers when the interior temperature reaches 75 degrees. Thermostats will trigger the exhaust fans at 85 degrees, to expel hot air out of the buildings and suck fresh air in. Construction started in early December, Mr. Duncan said, and will be completed in stages over the next several months. A completion date in May is projected for Bldg. 506; the improvements to Bldgs. 412, 469 and 510 are to be finished in the early fall; and work on Bldgs. 1146 and 3001A is expected to be finished "around June," he said. Mr. Duncan said the work is being performed by a private company that's a joint venture, under contract with the U.S. Army Corps of Engineers.
