August 19, 2025— Taipei/Jakarta — “The Flux,” a green building proposal by a team including Universitas Indonesia, has secured a finalist spot at the Net Zero Tech International Contest, a global competition hosted by National Taiwan University and the TECO Technology Foundation with support from Taiwan’s Ministry of Education, Ministry of Environment, and Ministry of Economic Affairs. This year’s contest received 230 proposals from 11 countries, involving 1,150 participants. Twenty teams advanced to the International Contest final, with Universitas Indonesia the only representative from Indonesia.

The contest supports Taiwan’s 2050 Net Zero Emissions Pathway by cultivating young innovators in energy and renewable technology. Finalists in the International Contest present for six minutes, followed by a six-minute demonstration and Q&A on the exhibition floor. All sessions are conducted in English. Judges evaluate both the quality of the project and the clarity of communication.

The Flux targets near-zero emissions by 2030 and net zero by 2050 across two French sites: a retrofit in Chimilin and a new build in Villefontaine. The proposal applies a unified architectural language through Shearing Layer thinking and rammed earth (pisé) construction. The design emphasizes local materials, traditional techniques, passive daylighting and ventilation, water-sensitive landscaping, passive thermal management, and modularity with design for disassembly to reduce embodied and operational carbon.

Performance was validated through a suite of simulations and assessments, including THERM and Ubakus for envelope performance, ETABS for structural integrity, Ladybug and Honeybee for orientation optimization and comfort, and One Click LCA and DesignBuilder for operational and embodied carbon analysis. The project aligns with international sustainability frameworks such as LEED, BREEAM, and DGNB and achieved strong life cycle assessment results.

By integrating human activity, natural systems, and cultural heritage within a circular design approach, The Flux presents a scalable blueprint for adaptive, lower-carbon architecture. Its selection as a finalist highlights Indonesian contributions to net zero innovation on the international stage.
