CHIANG MAI WORLD GREEN CITY AND SMART COMMUNITY
Asian Development College for Community Economy and Technology (adiCET), Chiang Mai Rajabhat University aimed to be the green institution to facilitate the sustainable development of the local community. adiCET established the Chiang Mai World Green City (CMGC) as the living laboratory for green technologies to showcase real applications for sustainable living. CMGC is developed from over 60 sustainable energy research and development projects. CMGC covers about 20 rai and comprised of 3 distinct zones. Zone A is the Smart Community where students and staff lived and worked in a 100% renewable energy based community with AC/DC Smart Grid. Smart Community also focused on sustainability in 5 areas: Energy, Food, Residential, Economics and Environment. Zone B is the green college and has classroom and seminar halls. Zone C is the Green Technology Exhibition Center.
CMGC and the Smart Community focused on the implementation of Community Power for small rural communities. The aim is to develop an affordable/appropriate sustainable energy system to enhance the livelihood and occupation of the community. Community power is defined as decentralized hybrid renewable energy based system from natural resources and agricultural wastes. The integration of PV, biomass gasifier, biodiesel generator and biogas systems are the key for sustainable energy development in the community. adiCET research team was able to develop a Smart Community that uses 100% electricity from 50.5 kW PV systems. The power is distributed through a Smart DC microgrid network making it the first community in the world that uses DC appliances. The Smart Community is also flexible as the platform to test both AC and DC usability. In addition, adiCET has a 700 kW PV on-grid system for the university as the test-bed and learning center for community power systems. These systems provided real hands-on experience to monitor and assess PV for On-grid and Off-grid System. adiCET aims to be the integrator of green technology and renewable energy. The smart grid is the platform to integrate these technologies.
The Smart Community also have biogas digesters, biomass gasification and diesel generators integrate as hybrid energy systems. The energy (power and heat) are used in the green city in the daily lives of green city citizens. For example, the biogas is used for the kitchen. The electricity from PV are used for solar pumping in farm for the Smart Farm/low carbon agriculture. The Smart Farm uses soil moisture sensors and smart logic to determine the optimal usage of water appropriate for specific vegetables. In addition, the buildings in the Chiang Mai are designed to be eco-friendly and energy efficient such as energy efficient seminar hall with EPS foam technology and PV rooftop. The roads in CMGC are carbon sink roads which uses approximately 2 million waste plastic bags to construction the 2 km asphaltic road.
adiCET provides short course and technology transfer training at the CMGC and in the local community. Mainly, adiCET provide training in renewable energy technology application such as PV for water pumping in agriculture, PV for household usages, low cost community PV systems, and community biogas digesters. adiCET team are also the consultant for energy efficiency, energy policy and planning and also energy awareness programs for target participants all over Thailand. adiCET strives to be the leading institution to promote and develop the technologies and management model for the betterment of the community.
