Join It Sustainable Technology Proposed A Facade Net-Zero Solution to Accelerate Public Buildings Transformation
To achieve Net-Zero by 2050, Join It Sustainable Technology formally proposed its "Facade-Centric Net-Zero Empirical Solutions for Existing Buildings" today (24th) during the " Existing Public Buildings Net-Zero Innovation Technology Application - Field Demonstration and Promotion Activity." At the real-site of the Architecture and Building Research Institute (ABRI), demonstrating the integrated application of color-painted PV combined with energy storage and smart energy management.
The Public Existing Building Demonstration Site at the ABRI Materials Testing Center integrates color-painted PV, energy storage, and smart energy management systems into building facades. Providing the evidence of a feasible engineering path for transforming existing structures into net-zero buildings without compromising structural safety or functional utility.
The event, hosted by ABRI and executed by the Industrial Technology Research Institute (ITRI), brought local government agencies, architecture and engineering, and industry representatives together. Invited to share its technical expertise, Joint It Sustainable Technology positioned itself not merely as a supplier, but as a strategic partner assisting the government in transforming "Net-Zero for existing buildings" from a policy into a deliverable engineering path adopted by official systems.
Join It Sustainable Technology: Net-Zero for Existing Buildings Beyond the Rooftop
During the presentation, Join It Sustainable Technology pointed out that Taiwan has a massive volume of existing buildings. If rooftops remain the single carrier for renewable energy, it will be difficult to support the overall demand for net-zero transformation. A truly scalable solution must return to the building itself and redefine the functional role of the "facade."
By integrating color-painted PV with energy storage and smart energy management systems, exterior walls are no longer just aesthetic or structural components; they become power-generating, energy-storing, manageable, and verifiable energy interfaces. This model is particularly suitable for existing buildings, allowing for the gradual introduction of net-zero solutions without compromising structural safety or urban aesthetics, enabling public buildings to quickly produce verifiable carbon reduction results.
Join It Sustainable Technology emphasized: "The key to net-zero is not just having innovative technology, but whether that technology can be validated by policy, integrated into the system, and successfully executed by engineering teams."
Policy Alignment: Responding to ABRI’s Governance Direction
Xu Yan-Xing, Deputy Director of ABRI, noted that public existing buildings carry significant policy weight as early demonstrators. Through field verification, government agencies can establish a consistent logic for technology adoption and judgment criteria. This ensures that net-zero policies move beyond principled declarations to become replicable implementation models.
Xu Yan-Xing, Deputy Director of the Architecture and Building Research Institute (ABRI) of the Ministry of the Interior, stated that existing public buildings are pivotal for policy demonstration and scaling. Through real-site verification, consistent technical implementation logic and evaluation benchmarks can be established, thereby strengthening the feasibility and replicability of net-zero building policies.
The "Implementing Net-Zero Innovative Technology in Existing Public Buildings—Field Demonstration and Promotion Event" brought together representatives from central ministries, local governments, research institutions, and the industry. Through the exchange of practical case studies, the event established a common understanding and strategic direction for the net-zero transformation of existing public buildings.
Join It Sustainable Technology stated that this demonstration response ABRI’s direction: using public buildings as an "intermediary field" between policy and industry, translating policy needs into "engineering language" while re-integrating industrial solutions into governance logic.
During the event, Hsueh Weili, Founder of Join It Sustainable Technology, provided a technical briefing on the "energization" of existing building facades. He detailed the process of upgrading exterior walls from passive components into active energy interfaces capable of power generation, energy storage, and management. This serves as a vital supplementary solution for public buildings striving to achieve Near Net-Zero and Net-Zero Carbon goals.
ITRI’s Perspective: System Integration is Key to Scalability
Jian Ren-de, Director of the Near-Zero Carbon Building Promotion Team at ITRI, pointed out that net-zero building is a systems engineering challenge. The key lies not in the performance of a single piece of equipment, but in the integration capability of energy saving, generation, storage, and smart management.
Jian Ren-de, Director at the Industrial Technology Research Institute (ITRI), pointed out during the "Public Existing Buildings Net-Zero Innovation Technology Application—Field Demonstration and Promotion Event" that net-zero building is a complex systems engineering task. He emphasized that only by integrating energy saving, energy generation, energy storage, and smart energy management can a replicable and scalable transformation model for public buildings be established.
Join It Sustainable Technology noted that this view aligns with its core philosophy. Only by modularizing and standardizing processes can the threshold for adoption be lowered for government agencies, shortening the distance from policy decision-making to engineering implementation.
Three Pillars of Practical Net-Zero for Existing Buildings
Join It Sustainable Technology summarized three keys to promoting net-zero in existing buildings:
- Facades as Incremental, Not Replacement: Since rooftop space is limited, only facades can support large-scale transformation.
- Engineering Must Be Deliverable: Technology must be verifiable, maintainable, and institutionalized.
- Demonstrations Must Be Replicable: Success at a single site is not enough; a standardized path must be formed for all agencies.
Conclusion: Creating Value by "Finishing" the Job for Government
Join It Sustainable Technology will continue to collaborate with ABRI, ITRI, and various government levels. Through more field demonstrations, the company aims to establish engineering standards and promotion models for facade net-zero solutions. Net-zero is not about starting from zero; it is about optimizing existing buildings to their fullest potential as a tangible governance achievement.
