Currently, Taiwan's smart green building industry has reached a scale of 3.1 billion New Taiwan Dollars. The Taiwan Tech Green Jiajia Entrepreneurship Team started by integrating green algae products into green buildings and developed outdoor algae module green walls and indoor algae air purifiers, aiming to achieve initial success in biomass energy research and sustainable carbon reduction design. Their goal is to create a sustainable, comfortable, and innovative lifestyle within the limits of human knowledge theory.

The Green Jiajia Team set up a booth at the 2023 Meet Taipei Innovation and Entrepreneurship Carnival to promote their products.

The outdoor green algae green wall features a light-chasing green algae cultivation facade module combined with a light sensor. Compared to the custom-integrated residential structures already available in Germany, it adds light sensors that can rotate to follow the angle of the sun, and it possesses a one-stop management system for design, mold-making, piping, power distribution, and manufacturing.

The Green Jiajia team has established a company, with the founder Hong-Yi Lai who is a doctoral candidate in the Department of Architecture at Taiwan Tech. He explained that current product development utilizes AIoT (Artificial Intelligence combined with Internet of Things) to optimize parameters for green algae cultivation. The team has also developed a mobile app backend to assist in establishing cloud-based data monitoring, ranging from optimizing indoor air quality to assisting in carbon footprint analysis and ESG reporting for businesses.

Hong-Yi Lai stated that the team originally focused on plants but later discovered Taiwan's globally renowned green algae cultivation quality in closed systems. Consequently, they created the only indoor and outdoor algae cultivation system on the market that is simple, efficient, and purifying. It is customizable and incorporates technology for smart cultivation via a mobile app.

Apart from Hong-Yi Lai, the company currently has two other employees. Approximately 90% of their time is dedicated to research and development. Besides team members with backgrounds in architecture, they also collaborate closely with Professor Alchris Woo Go from the Department of Chemical Engineering at Taiwan Tech to develop nutrient solutions for homegrown algae and calculate algae's carbon dioxide absorption capacity. The team actively engages with the public sector and companies interested in sustainability issues.

Since 2015, the Green Jiajia team has been deeply involved in product development. In 2020, they ranked in the top 10 globally at the Global Biomimicry Design Competition, being the only representative from Taiwan. Guidance from the Taiwan Tech Incubation Center aided them in being selected as an outstanding team in the second phase of the U-start innovation and entrepreneurship program in 2023. Hong-Yi Lai greatly appreciates the careful guidance provided by the incubation center, including professional consultations with industry experts, which helped them gain a deeper understanding of various aspects of company establishment, such as arranging company shares and designing related professional business profit and loss assessment sheets and cost-revenue estimates, etc. These are all crucial issues that must be faced and resolved on the entrepreneurial journey.

Hong-Yi Lai recalled that during the entrepreneurial competition, besides financial support, gaining valuable experience and learning opportunities were more important. Initially, the team mainly focused on technical aspects. However, they discovered that apart from technical issues, determining the company's long-term, medium-term, and short-term goals; negotiating with partner companies; and transforming technology into commercial products were all challenges that needed to be addressed. These were lessons learned during the entrepreneurial competition, helping them understand how to focus on technical development while not forgetting the company's vision and customer needs.
