Abstract
Methods for integrated room management in a building management system and corresponding systems and computer-readable mediums. A method includes determining a solar heat gain coefficient (SHGC) for a room in a building and determining predicted room temperatures for the room at the plurality of time intervals based on the SHGC and a plurality of window blinds tilt angles. The method includes determining illumination heat and illumination energy for the room and determining climate energy for the room. The method includes determining a total room energy as a function of the window blinds tilt angles based on the climate energy, illumination energy, and predicted room temperatures. The method includes determining an optimal blind tilt angle that minimizes the total room energy at each of the time intervals and controlling the tilt angles of window blinds according to the optimal blind tilt angle.
