1. A control system for controlling the environmental conditions within a building comprising:

  • at least one onsite component located at the building and further comprising;

    a central controller that stores a control algorithm,at least one sensor unit for collecting at least one environmental measurement corresponding to a measured temperature condition from within the building and transmitting the environmental measurement to the central controller, wherein the central controller automatically aggregates the environmental measurements and generates an environmental control instruction based on the environmental measurement,at least one secondary control unit operably linked to an HVAC system,an offsite component located remotely from the building and networked to the at least one onsite component, wherein the offsite component evaluates characteristics of the environmental control instruction to determine an effectiveness of the control algorithm, and wherein the offsite component remotely modifies at least one operating instruction of the control algorithm to generate a new temperature setpoint; and

    wherein regular updates and monitoring of the at least one onsite component are offered through a subscription service to monitor the efficacy of the control algorithm and wherein the central controller transmits the at least one operating instruction to the secondary control unit governing operation of the HVAC system to achieve a desired environmental condition within the building.
