A panel element is for use in a modular wall system with vertical support structures. The panel element includes a panel having a planar surface and side edges transverse to the planar surface, the planar surface can be hung up on at least one of the vertical support structures. An electrical connector is provided on the back of the panel, including a first connector pin and a connector second pin for forming electrical connections. The first and second connector pins fit within openings in a surface of one of the vertical support structure. The connector pins are movably coupled to the panel so as to allow movement of the first and second connector pins in at least one direction parallel to the planar surface between an extended position and a pulled-in position.

A roofing, cladding or siding module is described. The module comprises an underlapping region adapted to be substantially covered by an exposed region of an adjacent overlapping module when installed on a building surface. A plurality of projections are formed on an underside of the underlapping region. The projections are feet to support the module on the building surface to provide a gap between the module and the building surface, and/or provide a profile on the underside of the underlapping region to define a pathway for air flow between the module and the building surface. Each projection is formed by a downwardly projecting portion of the underlapping region with a corresponding cavity in an upper side of the underlapping region, and the cavity is shaped to prevent or minimize water pooling in the cavity.

A glass light-emitting tile may include a light-transmissive glass plate, a glass substrate and a light guide plate. The light guide plate may be arranged between the light-transmissive glass plate and the glass substrate. A light-emitting diode (LED) lamp may be provided on a side of the light guide plate. The light-transmissive glass plate and the glass substrate may be glued together using a sealant. The glass light-emitting tile may having a tile and/or a stone-textured coating that may be low cost, may provide a high production efficiency, and may provide flexible customization. The tile may be used indoors and/or outdoors.

Systems and methods for providing a prefabricated, custom coffered ceiling apparatus, which includes an outer box frame, custom interior frame designs in accordance with an order, wherein the interior frame designs are attached to the outer box frame, and crown molding on the outside of the box frame at the top of the coffer. The coffers are finished with paint or various wood finished in accordance with an order. The coffer system is easily assembled via a groove created at the top of the coffer for easy installation at the desired location. Lighting fixtures or other desired elements may be mounted within the apparatus.
