Disclosed are methods for incorporating core materials such as phase change materials or admixtures into building materials like concrete. The methods use cenospheres, which are then etched and loaded with the core material. The composition can also be coated with a thin film. Compositions containing cenospheres loaded with the various core materials are disclosed, as are building materials containing such compositions.

A latent heat storage gypsum plate includes: a gypsum plate having a first main face and a second main face located on an opposite side of the gypsum plate from the first main face; and a latent heat storage layer disposed over at least part of the first main face of the gypsum plate and including a latent heat storage material and a binder. A heat storage capacity of the latent heat storage gypsum plate is 260 kJ/m.sup.2 or more, the heat storage capacity being measured in a measurement temperature range of from 15? C. through 35? C. through heat storage capacity measurement specified in ASTM C 1784. The latent heat storage gypsum plate exhibits heat generation property grade 1 as evaluated by a heat generation property test specified in JIS A 6901 (2014), with the face in which the latent heat storage layer is disposed being set as a back face.
