The disclosed technology provides a module useful in constructing an energy efficient, durable building structure, the module including walls to form a vacuous, sealed chamber substantially void of structural elements, materials and gaseous molecules. One or more ribs are affixed to or formed integral with an exterior surface of the exterior wall of the module, extending the width of the module. The disclosed technology further provides a vacuum apparatus which may be incorporated in communication with the vacuous, sealed chamber, for creating and maintaining a vacuum within the module. A method of controlling heat transfer within a structure is also provided, utilizing the modules as herein disclosed, each module being coupled with a vacuum apparatus in communication with the vacuous, sealed chamber, for creating and maintaining a vacuum within the module.

An insulated structure comprises a first panel and a second panel coupled to the first panel. The first and second panels define an insulating cavity therebetween. A port is defined by the second panel. The port is an opening into the insulating cavity. A connector is coupled to the second panel. A tube is coupled to the connector and extends parallel along the second panel.

A system of vacuum insulation panels provides an adjustable insulative resistance in a building envelope. The system includes a number of vacuum insulation panels installed to form separate insulation zones in the building envelope with airflow communication between selected vacuum insulation panels in a zone. A vacuum pump connects to vacuum pump connector assemblies of each vacuum insulation panel to thereby increase or decrease the amount of vacuum in each vacuum insulation panels. A digital processor controls the activation of the vacuum pump to adjust the insulative resistance of the building envelope. Thermostats provide real-time temperature information for each zone inside the building and for the outside temperature. Based on the temperature readings and other pre-programmed information the digital processor independently adjusts the isolative resistance of different zones of the building to maximize the heating and cooling efficiency.

A system of structural interlocking panels for forming disaster-resistant buildings, comprising: a hollow, internally-braced, vacuum-insulated panel shell having at least two interlocking sides, the first side having a convex-inward single-curvature, the second side having a straight surface, the third side having a straight surface with at least one integral tongue with at least one head extending vertically-upward for receiving a complementary groove of a first side of an adjacent panel. Panels are thus vertically slide-locked along panel sides and faces, thereby triggering automatic snap joints that prevent backward movement of the panel. The system can assemble spheres, cylinders, toroids, tetrahedrons, flat shapes, and irregular shapes.

The present invention provides an inflatable panel (10) comprising an inflatable first part (12) having an internal compartment (13); an inflatable second part (14) having an internal compartment (15); and a third part (16) connecting the first part (12) to the second part (14) at a periphery of the first and second parts (12, 14). The first, second, and third parts (12, 14, 16) together define a sealed enclosure (18) therebetween. The inflatable panel (10) also includes means for evacuating air from the sealed enclosure (18), and said sealed enclosure is configured to increase thermal insulation between the first part (12) and the second part (14).

At present, all public spaces and offices around the world use light steel hangers and 22 ceiling board or 48 indoor compartment gypsum board for the beauty and fire protection. Thermally soundproof, but the board is not encapsulated with a metal film and then vacuumed. In the long term, the moisture of the water molecules contained in the micron-sized pores would have been transported through the asbestos fibers, therefore become the medium for conducting sound waves and heat. It is necessary to enclose the board with metal film and then vacuumed in order to improve fire and sound insulation.

A window body includes two sheets of plate members that form a space sandwiched therebetween, a liquid HF that is enclosed between the two sheets of plate members, and a slop having a liquid circulation structure in which a reservoir Res for the hydraulic fluid HF is formed on one plate member side of the two sheets of plate members, the hydraulic fluid HF in the reservoir Res evaporated by heat of the one plate member side reaches the other plate member side, and the hydraulic fluid HF condensed on the other plate member side returns to the reservoir Res again.

The present invention relates to a heat-insulating structural material, which: firstly, can minimize or prevent a thermal bridge by improving the structure of the connection part of the heat-insulating structural material; secondly, improves insulation performance by arranging a vacuum insulation material inside the core layer of the heat-insulating structural material; and thirdly, increases structural stiffness by forming the core layer from a non-foaming polymer material having excellent structural performance, prevents gas from moving in or out of the vacuum insulation material through the air-tight adhesive structure of the core layer, and can improve fire protection performance so as not to be vulnerable to fire, and thus the present invention is universally applicable to fields requiring insulation ability and structural performance.

A vacuum insulation panel manufacturing method that makes it possible to manufacture low-cost, high-performance vacuum insulation panels, and a vacuum insulation panel are provided. This method of manufacturing a vacuum insulation panel involves: a stacking step in which a first metal plate is stacked on one side of an insulating core material, and in which a backing member having an opening and a second metal plate having an evacuation port are stacked, with the opening and the evacuation port stacking, on the other surface of the core member in the order of backing member and second metal plate from the core member side; a first welding step for welding outwards of where the core member is arranged in the first metal plate and the second metal plate; an evacuating step from the evacuation port to create a vacuum in an inner area which is held between the first metal plate and the second metal plate and in which the core member is arranged; and a laser welding step in which, in a state in which the inner area is made into a vacuum by the evacuating step, the evacuation port is sealed by means of a sealing material and the sealing material, the second metal plate and the backing member are laser welded.
