A load control system for controlling an amount of daylight entering a space of a building through at least one window of a non-linear façade of the building with at least two distinct façade angles (φF), the load control system comprising: at least two motorized window treatments located along the non-linear façade for controlling the amount of daylight entering the space; and a system controller configured to transmit digital commands to the at least two motorized window treatments for controlling the at least two motorized window treatments, wherein the load control system is characterized by the system controller being configured to: calculate a position for the at least two motorized window treatments at each of a plurality of different times (tVAR) during a time interval using the at least two distinct façade angles, the position calculated to prevent a sunlight penetration distance from exceeding a sunlight penetration distance (dMAX) at each of the plurality of different times during the time interval; use the calculated positions at the plurality of different times during the time interval to determine a controlled position to which the at least two motorized window treatments will be controlled during the time interval; and automatically adjust the position of each of the at least two motorized window treatments to the controlled position so as to prevent the sunlight penetration distance from exceeding the sunlight penetration distance during the time interval. at least two motorized window treatments located along the non-linear façade for controlling the amount of daylight entering the space; and a system controller configured to transmit digital commands to the at least two motorized window treatments for controlling the at least two motorized window treatments, wherein the load control system is characterized by the system controller being configured to: calculate a position for the at least two motorized window treatments at each of a plurality of different times (tVAR) during a time interval using the at least two distinct façade angles, the position calculated to prevent a sunlight penetration distance from exceeding a sunlight penetration distance (dMAX) at each of the plurality of different times during the time interval; use the calculated positions at the plurality of different times during the time interval to determine a controlled position to which the at least two motorized window treatments will be controlled during the time interval; and automatically adjust the position of each of the at least two motorized window treatments to the controlled position so as to prevent the sunlight penetration distance from exceeding the sunlight penetration distance during the time interval. calculate a position for the at least two motorized window treatments at each of a plurality of different times (tVAR) during a time interval using the at least two distinct façade angles, the position calculated to prevent a sunlight penetration distance from exceeding a sunlight penetration distance (dMAX) at each of the plurality of different times during the time interval; use the calculated positions at the plurality of different times during the time interval to determine a controlled position to which the at least two motorized window treatments will be controlled during the time interval; and automatically adjust the position of each of the at least two motorized window treatments to the controlled position so as to prevent the sunlight penetration distance from exceeding the sunlight penetration distance during the time interval. <EOS>
