Energy-Saving Container Prefabricated House
An energy-saving container prefabricated house is a building form that is transformed using containers as basic modules, featuring environmental protection, flexibility, and low cost. The following is an introduction from multiple aspects:
Production Mode and Energy-Saving Effects
It adopts the 'factory manufacturing + on-site installation' mode, with no construction waste at the site. Compared with traditional projects, the water consumption for construction and concrete loss are reduced by about 60%, construction and decoration waste are reduced by about 70%, energy is saved by about 50%, and the overall production efficiency is increased by 10-15 times.
Sustainability
The house can be relocated as a whole without disassembly, moving with the container and its contents. It can be hoisted more than a thousand times and has a service life of over 20 years without loss. It supports inventory and recycling. The walls, ceilings, circuits, doors, and windows are decorated once, eliminating the need for repeated renovations during long-term use.
Energy-Saving in Transportation and Installation
It can be disassembled into panel packaging. A 17.5-meter flatbed truck can transport 12 sets of accessories, and a 40-foot high-cube container can hold 6 sets of accessories for sea transportation, reducing transportation costs. For short distances, prefabricated whole containers can be transported, and two workers can complete the installation of a single container in 20 minutes on site. After connecting to water and electricity, it can be used immediately, achieving 'installation and use on the same day'.
Technical Characteristics
It features highly integrated and factory-based production, modular design, top-bottom separation, and simple assembly. It has anti-seismic and wind-resistant, waterproof, fireproof, and corrosion-resistant properties, is lightweight, and has low maintenance costs. For example, the Tianfeng movable container house is designed to withstand an 8-degree seismic intensity, with a design wind pressure of 0.85 kN/m² and a roof waterproof life of 15 years.
Application Areas
It is widely used in construction site dormitories, temporary housing, creative spaces, post-disaster emergency buildings, etc. For example, the 2026 Nagoya Asian Games in Japan will use containers to build the Asian Games Village, Zaozhuang in Shandong Province will create a characteristic homestay scenic area, emergency medical facility construction, and commercial innovations such as 24-hour self-service fitness pods.
Structural Design and Lifespan
The Tianfeng movable container house adopts a wall self-supporting system with a structural design life of 30 years and a roof waterproof life of 15 years. The inner and outer walls use 50mm or 75mm thick rock wool/polyurethane sandwich panels, the corner columns are made of 3mm thick Q345B galvanized steel plates, and the top and bottom frame materials are Q345 with a galvanizing amount of 100g/㎡, ensuring structural stability.
