Energy saving temperature and humidity sensing and control processes, system and apparatuses operate effectively in response to signals received from occupants and to dynamic responses of building and its heating, ventilating and air conditioning system. The disclosed processes, apparatuses and system utilize thermostats equipped with a drift ramping and hold time to save energy; the thermostats only need resetting to a neutral/comfort set point which is accomplished by means of a push button or touch plate. The disclosed systems are pre-programmed and set so that occupants will be confortable although the temperature within the building drifts because the rate of drift is controlled to a gradual and normally unnoticed change.
