A system for conditioning air in a building including a fan-coil unit arranged adjacent to or within an indoor space within the building and additionally configured to at least one of heat and cool the air of the indoor space, and a scrubber arranged adjacent to or within the indoor space, the scrubber configured during a scrub cycle for scrubbing of indoor air from the indoor space. The scrubber includes one or more adsorbent materials arranged therein to adsorb at least one predetermined gas from the indoor air during the scrub cycle, a source of outdoor air, and an exhaust, wherein the scrubber is configured during a purge cycle to direct a purging air flow received from the source of outdoor air over and/or through the adsorbent materials to purge at least a portion of the at least one predetermined gas adsorbed by the adsorbent materials during the scrub cycle from the adsorbent materials and thereafter exhausting the flow via the exhaust.

1. An air treatment system for conditioning air in a building, comprising: a fan-coil unit arranged adjacent to or within the indoor space;a scrubber configured during a scrub cycle to scrub air from an indoor space of the building, and being positioned within or adjacent the indoor space, the scrubber including: one or more adsorbent materials arranged therein to adsorb at least one predetermined gas from the air of the indoor space during the scrub cycle,a source of outdoor air, andan exhaust,wherein the scrubber is configured: during a purge cycle to direct a purging air flow, received via the source of outdoor air, over and/or through the adsorbent materials to purge at least a portion of the at least one predetermined gas adsorbed by the adsorbent materials during the scrub cycle from the adsorbent materials and thereafter exhausting the flow via the exhaust, andduring a scrub cycle to supply scrubbed air to the fan-coil unit. 2. A system according to claim 1, wherein the scrubber is configured to supply scrubbed air exiting the scrubber to the indoor space. 3. A method for conditioning air in a building, comprising: circulating indoor air of an indoor space via a fan-coil unit;optionally heating or cooling the circulated indoor air;scrubbing the indoor air during a scrub cycle using a scrubber placed within or adjacent to the indoor space, the scrubber comprising: one or more adsorbent materials arranged therein to adsorb at least one predetermined gas from the air of the indoor space during the scrub cycle;a source of outdoor air, and an outdoor exhaust;flowing a purging air flow received via the source of outdoor air over and/or through the one or more adsorbent materials so as to purge the adsorbent materials of at least a portion of the at least one gas adsorbed by the one or more adsorbent materials; andthereafter exhausting the purging air flow via the exhaust. 4. The method of claim 3, wherein the fan-coil unit is supplied refrigerant or heating fluid from a variable refrigerant flow (VRF) system. 5. The method of claim 3, wherein the fan-coil unit is supplied chilled or heated water from a central chiller or boiler. 6. The method of claim 3, wherein the scrubber further comprises at least one of a damper and a fan, and wherein the method further comprises switching the scrubber from the scrub cycle to the purge cycle using the at least one of the fan and the damper. 7. The method of claim 3, further comprising performing the switching according to at least one of: a preset schedule, a predetermined level of the predetermined gas, the enclosed space occupancy level, a manual trigger, a signaled command and an externally signaled command. 8. A system for conditioning air in a building comprising: a plurality of indoor spaces within the building; a plurality of fan-coil units arranged adjacent to or within the plurality of indoor spaces and additionally configured to at least one of heat and cool the air of the plurality of indoor spaces; anda scrubber arranged within the building, the scrubber configured during a scrub cycle for scrubbing of indoor air from the plurality of indoor spaces, the scrubber including:one or more adsorbent materials arranged therein to adsorb at least one predetermined gas from the indoor air during the scrub cycle;a source of outdoor air, andan exhaust,wherein the scrubber is configured during a purge cycle to direct a purging air flow received from the source of outdoor air over and/or through the adsorbent materials to purge at least a portion of the at least one predetermined gas adsorbed by the adsorbent materials during the scrub cycle from the adsorbent materials and thereafter exhausting the flow via the exhaust. 9. The system of claim 8 wherein the fan-coil unit is supplied refrigerant or heating fluid from a variable refrigerant flow (VRF) system. 10. The system of claim 8 wherein more than one of the plurality of fan-coil units is supplied refrigerant or heating fluid from a common variable refrigerant flow (VRF) system. 11. The system of claim 8 wherein the fan-coil unit is supplied chilled or heated water from a central chiller or boiler. 12. The system of claim 8 wherein scrubbed air exiting the scrubber is directed to the plurality of indoor spaces via conduits. 13. The system of claim 8 wherein indoor air is directed to the scrubber from the plurality of indoor spaces via conduits. 14. A system of claim 13 wherein the conduits are installed and configured for directing the indoor air from the plurality of indoor spaces to the scrubber. 15. A system of claim 13 wherein the conduits are pre-existing in the building. 16. A system of claim 15 wherein the pre-existing conduits are configured for ventilation, elevators, exhaust, or smoke exhaust. 17. A system of claim 8 and comprising a pre-conditioning unit configured to at least heat or cool outside air or scrubbed air exiting the scrubber and direct the preconditioned air to the plurality of indoor spaces. 18. A system of claim 17 wherein the pre-conditioned air is directed to the plurality of indoor spaces via conduits. 19. The system of claim 8 where the predetermined gas is selected from the group consisting of: carbon dioxide, volatile organic compounds, sulfur oxides, radon, nitrous oxides and carbon monoxide.
