This case study showcases a prefabricated ultra-low energy consumption housing solution that transforms residential construction through factory pre-production, modular structural systems, and integrated building components. By minimizing on-site work, cutting project timelines by 30%+, and delivering energy-efficient, eco-friendly living spaces, this solution addresses core pain points of traditional construction—making it ideal for rural development, cultural tourism, and residential industrialization projects.
Project Background: Reimagining Residential Construction
Traditional residential construction relies heavily on on-site concrete pouring, formwork installation, and scattered decoration work—leading to long timelines, high material waste, and inconsistent quality. As global demand for sustainable, efficient building solutions grows, prefabricated ultra-low energy consumption housing has emerged as a transformative alternative. This case study focuses on a solution that centralizes core production in factories, then assembles components on-site—combining speed, standardization, and energy efficiency to redefine modern housing.
Modular Structural Systems: The Foundation of Efficient Construction
This prefabricated housing solution leverages three specialized modular structural systems, each tailored to balance strength, energy efficiency, and installation speed:
1. Steel Frame + PC Component System
At the core of this system is an embedded panel with a three-layer structure: inner wall panel, thermal insulation layer, and outer wall panel. The outer panel connects to the steel beam via angle steel, forming a unified structure integrated with the steel frame. This design eliminates the need for on-site formwork and reduces on-site labor intensity—while ensuring structural stability and thermal insulation performance aligned with ultra-low energy consumption standards.
2. Steel Frame + Integrated Self-Insulation Wall
This system uses a steel frame as the primary structural support, paired with a steel pipe truss wall as the enclosure. The composite structure merges load-bearing capacity with built-in insulation, eliminating the need for separate exterior insulation work. This integration cuts on-site construction steps and enhances the building’s overall energy efficiency, a key requirement for ultra-low energy consumption housing.
3. Steel and Wood Structure System
Dubbed “breathing houses,” steel and wood structures excel at adapting to air temperature and humidity changes, creating a comfortable internal living environment. Beyond comfort, wood acts as a “carbon-negative” building material: it binds and stores significant amounts of carbon dioxide from growth until it is processed into wood products. When combined with steel, this system further reduces carbon emissions—making it a sustainable choice for eco-focused projects.
Integrated Building Components: Standardized, High-Performance Parts
The solution’s efficiency is amplified by a full suite of prefabricated building components, produced in factories to strict standards and assembled on-site via dry methods:
1. Wall Maintenance System
The wall system uses high-performance materials, including fiber-reinforced composite insulation panels, fiber-reinforced lightweight wall panels, and high-pressure aerated concrete panels. These materials offer a unique combination of benefits:
2. Indoor & Outdoor Decoration
All decorative components (e.g., wall panels, flooring, ceiling materials) are pre-produced in factories, then installed on-site via dry methods. This approach enables “move-in ready” spaces immediately after assembly—with no damage to finished surfaces (unlike traditional wet decoration). Options include integrated bathroom solutions (to maximize small-space utility), hanging stone, metal suspended ceilings, and real stone paint—balancing aesthetics, durability, and installation speed.
3. Smart Home Parts & Components
The housing solution integrates a full smart home system, enabling remote control, security monitoring, and centralized management of all home appliances. A communication network is pre-installed throughout the house, allowing users to control lighting, temperature, security devices, and other functions directly via mobile phones—enhancing daily convenience and modern living experiences.
4. Housing “4S” Service
