Aspiring Citizens CleanTech (ACC) Pte. Ltd. is a clean energy startup founded by Dr. Andy Zheng, who graduated from the University of California, Berkeley with a PhD degree of Mechanical Engineering. The company’s long-term vision is to build the 21st century information freeway for a big open data exchange (BODE), which enables a data-driven approach towards a sustainable and prosperous global society: to better aid the decision-making of citizens' daily life and government’s civic management. This BODE model fits into Singapore’s Smart Nation vision, which can later be exported to the growing Asian cities after successful test-bedding in Singapore. Our initial focuses are: implementing these BODE solutions to elevate the efficiency in urban transportation, air quality, and solar PV installations.
