  • Patent number: 10288321
    Abstract: Methods for integrated room management in a building management system and corresponding systems and computer-readable mediums. A method includes determining (702) a solar heat gain coefficient (SHGC) for a room (400) in a building and determining (704) predicted open-loop room (400) temperatures at a plurality of time intervals based on the SHGC and a plurality of electrochromic glass (ECG) (408) tint levels. The method includes determining (706) illumination heat and illumination energy for the room (400) and determining (708) climate energy for the room (400). The method includes determining (710) a total room energy at each of the time intervals as a function of the ECG (408) tint levels based on the climate energy, illumination energy, and predicted open-loop room temperatures. The method includes determining (712) an optimal ECG (408) tint level that minimizes the total room energy at each of the time intervals and controlling (714) the ECG (408) tint levels according to the optimal ECG tint level.

  • Patent number: 7024258
    Abstract: A system and method generates test vectors and a corresponding test program to manipulate terminal units in a building system so pressure and flow measurements correspond to independent modeling equations. The pressure and flow responses of the building system to the test program manipulation may be used to compute loss coefficients for the modeling equations. The modeling equations may then be updated with the computed loss coefficients so a building simulation may be performed. The simulated static pressure response of the modeling equations may be compared to measured static pressures to evaluate the sufficiency of the modeling equations.

  • Patent number: 5963458
    Abstract: A DDC controller is disclosed which implements a control strategy that provides for near-optimal global set points, so that power consumption and therefore energy costs for operating a heating and/or cooling plant can be minimized. Tile controller can implement two chiller plant component models expressing chiller, chilled water pump, and air handler fan power as a function of chilled water supply/return differential temperature. The models are derived from a mathematical analysis using relations from fluid mechanics and heat transfer under the assumption of a steady-state load condition. The analysis applies to both constant speed and variable speed chillers, chilled water pumps, and air handler fans. Similar models are presented for a heating plant consisting of a hot water boiler, hot water pump, and air handler fan which relates power as a function of the hot water supply/return differential temperature.
