1. A building ceiling panel apparatus comprising:
a panel structure having a first surface and a second surface opposite the first surface;
a mounting system comprising:
a first rail configured to be mounted to the panel structure adjacent to a first edge of the panel structure, the first rail comprising at least one first notch, the at least one first notch comprising a first enclosure surface and a first notch opening, the first enclosure surface facing the first surface when the first rail is mounted to the panel structure; and
a second rail configured to be mounted to the panel structure adjacent to a second edge of the panel structure that is opposite the first edge of the panel structure, the second rail comprising at least one second notch, the at least one second notch comprising a second enclosure surface and a second notch opening, the second enclosure surface facing the first surface when the second rail is mounted to the panel structure; and
at least one container containing a phase change material, the at least one container configured to be positioned on the first surface of the panel structure so that a first end portion of the at least one container is located within the first notch opening of the first rail and is securable to the first surface by the first rail and a second end portion of the at least one container is located within the second notch opening of the second rail and is securable to the first surface by the second rail, wherein the at least one container is configured to be positioned on the panel structure at one of a plurality of selectable coupling positions so as to be in conductive thermal cooperation with the first surface of the panel structure;
and wherein the phase change material comprises water, calcium chloride, and a nucleating agent.
