New Container House Design

The design of new container houses requires a comprehensive consideration of core elements such as structural systems, material selection, thermal insulation, energy integration, and spatial layout to achieve a unified functionality and aesthetics.

1. Structural System and Material Selection

New container houses use steel frames as their skeletons, typically employing hot-dip galvanized square steel welding (e.g., 100×100mm or 80×80mm specifications) to ensure structural strength and corrosion resistance. Wall panels adopt a composite sandwich panel structure, with an outer layer of aluminum-zinc color-coated steel plate or metal integrated design, an intermediate layer filled with thermal insulation materials such as rock wool, glass wool, or polyurethane, and an inner layer selected according to needs, such as PVC-coated steel plates or wooden finishes. Roof design needs to optimize drainage performance, with curved or sloped roofs reducing water accumulation and lowering wind resistance.

2. Thermal Insulation and Climate Adaptability

For different climatic conditions, a multi-layer protective system needs to be constructed. Cold regions require an increase in the thickness of the thermal insulation layer (e.g., 80-100mm rock wool), combined with underfloor heating, air conditioning, and heat pump technologies to achieve ultra-low energy consumption (heat transfer coefficient K value ≤ 0.28W/㎡·K). Hot regions should adopt reflective coatings, ventilation layers, and insulated glass to reduce heat conduction. The waterproof rating needs to meet the IP66 standard to cope with harsh environments such as humidity and salt spray, with a design lifespan typically exceeding 20 years.

3. Energy Integration and Sustainability

The integration of photovoltaic power generation with buildings is an important trend. Customized crystalline silicon photovoltaic modules can be embedded into the roof and exterior facades, forming a 'power-generating skin,' which, combined with large-capacity energy storage batteries, enables off-grid operation. For example, solar energy during the day can meet the demands for air conditioning and lighting, while the energy storage system ensures continuous power supply on cloudy or rainy days. Additionally, ecological technologies such as rainwater harvesting and greywater reuse can further enhance sustainability.

4. Spatial Layout and Functional Flexibility

Modular design supports free combination and expansion. The standard size of a single module is 3 meters by 6 meters, with lengths extendable up to 12 meters. By arranging and stacking N modules, it can adapt to needs such as single-room homestays and multi-functional spaces. The interior space adopts a functional overlay strategy, such as integrating the kitchen and bathroom into a wet area, and using convertible furniture (e.g., folding tables, drop-down beds) in the living and sleeping areas to achieve day-night functional switching. Standardized door and window openings and pipeline interfaces reduce the need for later modifications.
