An affordable Zero-Energy prefabricated modular building such as for housing, in which a Layered disposition of Envelope elementsincluding Structural Insulated Panelsin the wall, floor and roof sections of the building's thermal Envelope, provide a highly energy-efficient Building Envelope, which together with a modular building Support Structure including Aeriated Frames, and an adequately sized renewable energy power generator system, inexpensively achieves the energetic independence of the building. A method is disclosed for the adaptation of the building's design and construction to the bio-climatic conditions of its projected location, in which different possible configurations of the relevant elements of the Building Envelope, the building structure and the renewable power generator system are evaluated, discarding those configurations which don't meet the defined acceptable criteria for energy-efficiency, thermal isolation and water condensation risks. The building has a low environmental impact thanks to reduced greenhouse emissions during its construction and useful life.

Aspects described herein are directed to compositions, systems, and methods of manufacturing a polymer-based construction material comprising polymeric resin and filler such as calcium carbonate (CaCO.sub.3). A surface of the polymer-based construction material may be treated such that the surface energy is increased from the material's inherent value to a predetermined value of at least 40 dynes/cm.sup.2. Further, the surface energy of the treated surface may persist within 20% of the predetermined value for at least three days.

A modular building unit for construction of a building comprises a structural frame 40 suitable for interconnection to another modular building unit in construction of the building; and a stud frame wall 80/82 internal to and fixed to the frame. The modular building unit is suitable for handling as a shipping container for transport.

A sleeping module and a modular sleeping structure with a plurality of sleeping modules. The sleeping modules has a housing which defines a space dimensioned to accommodate a user in at least a lie-flat position, an entrance to permit access to and exit from the space of the housing, an openable closure member provided with the housing to at least partially obstruct the entrance for isolating the space from the surroundings and a holder useful with the openable closure member is provided at the housing to releasably hold the openable closure member in a closed position by way of an attractive force.

The present invention relates to a modular building structure that can be used for storage in a yard or the like. It comprises a plurality of sidewall panels and roofing panels. At least some of the sidewall panels have a pair of opposing marginal edges with adjacent marginal edges being provided with flanges that can overlap one another. At least one of the marginal edges has a reinforcing channel secured to a bead portion thereof and extending along a substantial portion of the length of the bead edge.

A building assembly system that comprises thermoformed high density polyethylene molded components filled with high density polyurethane foam. The molded components are configured in a cube or triangle form and secured against a steel frame to provide a habitable constructed unit. The composition of the high density polyethylene molded components filled with high density polyurethane foam meets standards for the American Society for Testing and Materials for a habitable structure used by humans. The habitable structure can be used on land or water.

The present subject matter discloses an improved wall structure for a modular plastic shed, designed for easy on-site assembly using pre-constructed modular panels. The enhanced wall structure features T-shaped connection accessories that securely install the wall to the floor panels. Additionally, support columns with integrated reinforcement ribs are incorporated to further strengthen the overall structure. These support columns also feature pre-formed sockets, allowing for quick and straightforward attachment of the wall panels, simplifying the assembly process and improving structural integrity.
