Abstract: A system and method for automatically providing a fresh air exchange to a cargo unit is disclosed. The system includes a single gas sensor, preferably a carbon dioxide sensor, for providing an input to a controller which derives the carbon dioxide and oxygen levels in the unit. The controller then compares such derived values to preselected levels and selectively opens or closes air flow into the cargo unit in order to bring and maintain the desired oxygen and carbon dioxide levels within the unit.

Abstract: Air quality within a building is controlled by maintaining a count of people in the building and by ventilating the building with an amount of air dependent on the count. The count may be determined in accordance with an access control system and/or entry and exit sensors, such as infrared sensors.

Abstract: An HVAC system has two variable-air-volume (VAV) systems, a first VAV system for moving fresh air and a second VAV system for moving recycled air. Both the fresh air and recycled air are cooled and dehumidified by a single heat-exchanging coil. The fresh and recycled air streams travel independently in separate ducts until the air streams reach a remotely located mixing box where the air streams mix and ventilate into a room or zone of a building. The HVAC system uses carbon dioxide and temperature sensors in order to regulate the flow of fresh and recycled air to various mixing boxes throughout the building.
Abstract translation: HVAC系统具有两个可变风量（VAV）系统，用于移动新鲜空气的第一VAV系统和用于移动再循环空气的第二VAV系统。 新鲜空气和再循环空气都通过单个热交换盘管进行冷却和除湿。 新鲜和再循环的空气流在独立的管道中独立运行，直到空气流到达位于远处的混合箱，空气流混合并通风到建筑物的房间或区域。 HVAC系统使用二氧化碳和温度传感器来调节新鲜和再循环空气的流动到整个建筑物的各种混合箱。

Abstract: A system and method for passive hypoxic training provides a person with a low oxygen (hypoxic) environment. Oxygen sensors automatically monitor and control oxygen levels to maintain the altitude desired. CO2 levels are monitored and CO2 is eliminated so that the air a person breathes is substantially clean and fresh. Exposure to a high altitude environment produces physiological changes in a person's body, which becomes more efficient at absorbing and transporting oxygen. Using the present method and system, athletes obtain the benefits of sleeping at a simulated altitude in the user's own home for six to twelve hours, rather than traditional altitude therapies in which athletes spend two to three weeks at high altitude before an athletic competition to obtain similar benefits. This system allows for nulllive high train lownull altitude training that has been shown in controlled studies to provide superior benefits to nulllive high train highnull training.

Abstract: A method of monitoring building compliance with healthy building guidelines includes obtaining current parameter values for a plurality of different parameters from a plurality of sensors disposed within a plurality of different zones of a building. For each of the parameters, the current parameter value received from each of the plurality of different zones is compared with a corresponding healthy building range for that parameter as specified by the healthy building guidelines. A healthy building dashboard is displayed that includes a summary that shows, for each of the plurality of different parameters, how many zones of the plurality of different zones of the building are within the corresponding healthy building range for that parameter and/or how many zones of the plurality of different zones are not within the corresponding healthy building range for that parameter.
