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.
