With further reference to FIG. 6, At 625, a comfort level calculator is shown, which, in certain embodiments, is operationally able to calculate a near-optimal (or a value more optimal than the current one) comfort level for a designated space using any of the methods and systems disclosed herein. Once the comfort value is known, the modifier 140 is operationally able to adjust the defined space state to match the comfort value. In an embodiment, a building control system, which comprises at least one controller 605, further comprises time values 610. These time values may be the time of day, such as 7:00 am, may be a period of time, such as from 7 am to 7 pm, may be a time curve, or may be a different sort of time value. Weather values 615 may also be used in the comfort level calculations. These weather values may be temperature, humidity, dew point, etc. In some embodiments, the comfort level calculator may use a time value 610, and a weather value 615. Other values that may be included to calculate a comfort value comprise current air speed, humidity, noise level, lighting level, entertainment noise level, or the preferences 135 associated with the user 305.
