The Double-water Low-carbon Community Center stands as a milestone in sustainable architecture. As the first officially approved, large-scale multifunctional public building in China constructed primarily from engineered bamboo (glubam) frames and cross laminated bamboo and timber (CLBT) slabs, this project transcends traditional construction boundaries. Spanning 2,030 square meters with a height of 15 meters, the two-story facility serves as both a community hub and a tangible prototype for the future of eco-friendly urban living. It harmonizes renewable biomass materials with high-performance structural engineering to realize “Net-Zero” operation.
Guided by the concept of “Biophilia,” the building mimics organic forms of nature. The design features a geometrically complex, curved roof constructed from Twist Laminated Bamboo Timber (TLBT) plates, evoking the fluidity of waves. This aesthetic warmth extends to the interior, where floor slabs utilize Cross Laminated Bamboo Timber (CLBT). The result is a space that breathes, offering a warm, tactile contrast to the concrete jungle and fostering a deep connection between the community and nature.
The project overcomes significant engineering challenges to validate glubam as a viable alternative to steel and concrete. The structural system employs a robust glubam beam-column frame working with steel bracing for lateral stability. A key highlight is the grand entrance hall, featuring a dramatic “skip-floor” configuration with a 16.2-meter span, achieved through precision-manufactured glubam beams.
To ensure safety in a region prone to typhoons and earthquakes, the design integrates hybrid columns encasing steel sections in high-stress zones. Rigorous quality assurance, including cold-press lamination technologies and in-situ full-scale vibration tests, confirmed that the structure meets all safety requirements. Construction utilized a modern “platform” method, allowing for rapid prefabricated assembly that minimized site disturbance and construction waste.
Sustainability is the core ethos of this project. Beyond the carbon sequestration inherent in bamboo, the center achieves a “Net-Zero” energy standard. A rooftop solar photovoltaic system acts as an active energy generator, complementing the passive energy efficiency of the high-performance bamboo envelope. Fire safety is meticulously managed through charring rate calculations and a whole-building sprinkler system, proving that bio-based materials can meet strict public safety codes.
The Double-water Low-carbon Community Center demonstrates that engineered bamboo is no longer merely experimental but a resilient, aesthetically powerful solution for large-scale infrastructure. By successfully navigating the complexities of large-span dynamics and renewable energy integration, this project provides a scalable blueprint for sustainable, low-carbon communities of the future.
