Taiyuan Prefabricated Assembled Houses

Taiyuan's prefabricated assembled houses are developing rapidly under policy support, with clear implementation scopes, evaluation criteria, significant advantages, and broad prospects.

Policy Support

The 'Notice on Continuously Strengthening the Work of Prefabricated Buildings in Taiyuan City,' implemented on June 18, 2026, incorporates steel structures into the full-chain management of projects, expanding their application scope. Large public buildings funded by the government (with a single above-ground floor area of ≥20,000 square meters) should prioritize steel structures; commercial housing projects over 100,000 square meters and industrial buildings over 3,000 square meters must strictly adhere to prefabricated construction requirements; steel structures may become a prerequisite for public buildings such as schools and hospitals in the future.

Implementation Scope

• Government and State-Owned Enterprise Projects: Affordable housing, talent apartments, public buildings, bridges, and utility tunnels must adopt prefabricated technology; newly constructed offices, schools, and hospitals on allocated land should follow government-funded project regulations.
• Commercial Housing Projects: Projects with an above-ground floor area of ≥100,000 square meters must fully adopt prefabricated construction; those between 50,000 and 100,000 square meters must use it for at least 40% of the area.
• Industrial Buildings: Factories, warehouses, and ancillary buildings with a single above-ground floor area of ≥3,000 square meters must adopt prefabricated construction.
• Exemption Conditions: Some small ancillary buildings (e.g., garbage rooms, guardhouses with a single area of ≤2,000 square meters) or up to five single buildings may be exempted after confirmation by the competent authority.

Evaluation Criteria

According to Shanxi Province's 'Evaluation Criteria for Prefabricated Buildings' (DBJ04/T396), the prefabrication rate for prefabricated concrete buildings must be ≥50%, while that for steel and timber structure buildings must be ≥60%.

Advantages

• Efficient Construction: Components are prefabricated in factories and assembled on-site. A 100-square-meter integrated house can have its main structure erected in three days and be ready for occupancy in seven days.
• Environmental Protection and Energy Efficiency: Reduces construction waste by 80% and noise pollution by 50%; sandwich insulation panels and double-glazed windows improve winter insulation by 35% and reduce summer air conditioning energy consumption by 40%.
• Wide Application: Covers tourism homestays, agricultural offices, movable classrooms, and emergency shelter scenarios.
• Recycling Value: Steel can be recycled, reducing resource consumption.

Development Prospects

Taiyuan's integrated houses are upgrading towards 'zero-carbon buildings,' integrating solar roofs, rainwater recycling systems, and photovoltaic curtain wall technology. The market size is expected to expand at an annual growth rate of 18% over the next five years, becoming a mainstay of prefabricated construction.
