Abstract
A method and apparatus for controlling the environment within an enclosed space is provided. The apparatus monitors environmental variables, and responsive to the values of the environmental variables, estimates the rate at which a gas is being generated within the enclosed space. The apparatus generates control signals to control devices based on the rate at which the gas is being generated within the enclosed space. In the preferred embodiment, the apparatus estimates the rate at which carbon dioxide is being generated in the enclosed space. Based on the estimated carbon dioxide generation rate, the apparatus may be configured to control an HVAC system, a comfort control system, lights, alarms or other devices.
