A method of conditioning an environment includes generating, by a group feedback analysis system, a first comfort limit based on a first plurality of data points corresponding to user feedback of a group of users in an environment conditioned by an environmental conditioning system to identify the first comfort limit at a first extreme; generating, by the group feedback analysis system, a second comfort limit based on a second plurality of data points corresponding to user feedback of the group of users in the environment conditioned by the environmental conditioning system to identify the second comfort limit at a second extreme, the second extreme being opposite the first extreme; identifying, by the group feedback analysis system, a comfort region defined by the first comfort limit and the second comfort limit; and controlling the environmental conditioning system to maintain at least one environmental criterion within the comfort region.
