Methods and systems are provided for enhancing the air quality in buildings during a chemical and/or biological attack and/or when the air quality around a building drops to unacceptable levels. Preferably, relatively non-contaminated (clean) air is stored in one or more clean air reservoirs. Once stored, the clean air is selectively delivered to buildings when a chemical and/or biological attack is detected, and/or when the air quality around a building drops to unacceptable levels.

A system for selectively providing clean air to the interior space of a building after the detection of an event, comprising:a reservoir for storing air;a conduit for transferring the stored air to the interior space of the building;an inlet for providing air to the reservoir;sealing means for sealing the inlet to the reservoir either before or after the detection of the event; andreleasing means for selectively releasing at least some of the stored air in the sealed reservoir through the conduit. 2. A system according to claim 1 further comprising a compressor for pressurizing the stored air in the reservoir. 3. A system according to claim 2 further comprising a controller for actuating said releasing means. 4. A system according to claim 3 further comprising a pressure sensor for measuring the pressure of the air released to the conduit. 5. A system according to claim 4 wherein the controller controls said releasing means such that the pressure of the air released to the conduit is substantially constant over time. 6. A system according to claim 3 wherein the controller disengages the compressor when said releasing means is actuated. 7. A system according to claim 3 wherein the compressor includes an air inlet, the air inlet having an air inlet sensor for sensing one or more chemical and/or biological agents. 8. A system according to claim 7 wherein the controller disengages the compressor when the air inlet sensor detects one or more chemical and/or biological agents. 9. A system according to claim 7 wherein the air inlet of the compressor includes a filter. 10. A system according to claim 1 further comprising one or more boost fans positioned in the conduit to help transfer the air released from the reservoir to the building. 11. A system according to claim 1 wherein the reservoir is an underground reservoir. 12. A system according to claim 11 wherein the underground reservoir is a naturally formed underground reservoir. 13. A system according to claim 11 wherein the underground reservoir is a salt dome. 14. A system according to claim 11 wherein the underground reservoir is an ice cavern. 15. A system according to claim 11 wherein the underground reservoir has interior walls, and wherein the interior walls include a sealing layer. 16. A system according to claim 15 wherein the scaling layer includes a cement layer. 17. A system according to claim 14 wherein the sealing layer includes an elastomeric layer. 18. A system according to claim 11 wherein the underground reservoir houses an air bladder. 19. A system according to claim 11 wherein the underground reservoir is a man made tunnel. 20. A system according to claim 19 wherein the underground reservoir is a storm sewer with an air bladder therein. 21. A system according to claim 20, wherein the storm sewer includes one or more water level sensors that cause the air bladder to deflate when the water level in the storm sewer reaches a predetermined level. 22. A system according to claim 1 wherein the reservoir is a grain elevator. 23. A system according to claim 1 wherein the reservoir is a water tower. 24. A system according to claim 1 wherein the reservoir is a petroleum storage tank. 25. A system according to claim 1 wherein the reservoir is an inflatable building. 26.
