Tibet Prefabricated Housing Solution

The Tibet Prefabricated Housing Solution focuses on prefabricated buildings, modular integrated housing, and packing-box units, combined with policy support and technological optimization, to form a sustainable building system adapted to the plateau environment.

1. Prefabricated Building Solution

This solution primarily adopts the "prefabricated components + on-site assembly" model, led by the local enterprise Zangjian Technology. It transfers 80% of the construction processes to the factory, with only assembly and finishing required on-site. Its core advantages include:

• Efficiency Improvement: The construction period is shortened by more than 50% compared to traditional methods (from 12-18 months to 6-9 months), reducing unit costs while minimizing on-site dust and noise pollution.
• Technical Standards: Based on the "Technical Standard for Prefabricated Concrete Buildings on the Plateau" (DB54/T 0305-2023), it ensures structural safety and durability, adapting to high-altitude and cold environments.
• Typical Applications: It has been implemented in projects such as the Milin Bangzhong Resettlement Site and the Lhasa Economic Development Zone Demonstration Project, verifying its technical feasibility.

2. Modular Integrated Housing Solution

Designed for cold regions, modular housing adopts a factory-prefabricated, on-site assembly model. Core modules include walls, floors, and piping, connected precisely through standardized interfaces and BIM technology. Its features include:

• Materials and Structure: Utilizing light steel structures or composite panels, equipped with high-performance insulation materials and airtight designs, it effectively addresses challenges such as low temperatures, strong ultraviolet radiation, and large diurnal temperature variations.
• Functional Expandability: It supports flexible expansion and customization, suitable for various scenarios such as residential housing, medical stations, and schools, significantly shortening construction periods and reducing interference with the plateau ecosystem.

3. Packing-Box Unit Solution

As a derivative form of modular housing, packing-box units apply industrial prefabrication concepts, completing the main construction of residential functional units in the factory before transporting them to the site for assembly. Its advantages include:

• Controlled Production Environment: Key processes such as welding and insulation filling are completed in the factory, avoiding the impact of plateau low temperatures and low pressure on construction quality.
• Simplified Logistics and Construction: The transportation objects are transformed from scattered building materials to integrated functional boxes, simplifying supply chain management; on-site work focuses on connection and debugging, reducing noise, dust, and waste.

4. Policy and Industrial Support

The National Development and Reform Commission's "Catalogue of Encouraged Industries in the Western Region" (2024 edition) lists green buildings and prefabricated buildings in Tibet as encouraged industries. The Autonomous Region's Housing and Urban-Rural Development Department, in collaboration with enterprises, has formulated industry standards, driving the growth of prefabricated building capacity from 300,000 square meters per year in 2022 to 1.8 million square meters per year in 2025, with a compound annual growth rate of 52%. Lhasa, Shigatse, and Nyingchi have become major application areas.

5. Technological Adaptability Optimization

Local enterprises have developed specialized materials for the plateau environment (such as UV-resistant coatings and low-thermal-conductivity composite walls) and obtained third-party certifications to ensure compliance with building standards. Some enterprises possess "nomadic production capabilities," establishing mobile prefabrication workshops at project sites to further shorten material transportation distances and enhance construction efficiency.
