One of the greatest displays of the 2013 Taiwan Lantern Festival was the “Ring of Celestial Bliss,” a 70-meter wide, 270-degree projection screen and LED lighting show in the form of a partial ring, the largest of its type in the world. The Ring and its surrounding construction were based on low carbon concepts. The main body of the structure was built with reusable steel framework and the external skeleton was made of Taiwanese bamboo. In addition to recyclable materials used in the construction, the Ring also employs 155 LED strips for illumination, which can save up to 80% of the energy used by more common halogen lights. Short films on sustainability were projected on to the Ring during the festival to raise public awareness on environment sustainability and renewable energy application.
The construction process of the Ring was carefully monitored and adjusted to fit green architecture regulations. After careful calculation of the structure’s life cycle, it is estimated that the construction process of the Ring emitted 80% less greenhouse gases (GHG) compared to that of a concrete building of the same size, equaling to conserving 350 tons of carbon dioxide emission. GHG emission by using reusable steel skeleton and bamboo façade is 20.8% of common concrete auditoriums. High efficiency lighting and video projection consumes only 65.4% of energy than normal circumstances and waste processing consumes only 14.8%. in other words, the Ring’s 15 day exhibition period only emitted 94.7 tons of CO2 compared to 430 tons emitted in one night during the Taipei 101 new year fireworks.

The main contributions of the Ring are not limited to its function as an educational public art display, but rather in the reuse and recycling of its construction materials after the closing of the Lantern Festival activities. The steel framework was given to the Min Chuang Elementary School in Namasia for typhoon reconstruction. Namasia is a mountainous district in Kaohsiung and is the water source for two major rivers. During Typhoon Morakot in 2009, Namasia fell victim to serious flooding and landslides, resulting in the complete destruction of 3 elementary schools in the area. Fortunately, due to joint efforts from the Kaohsiung City government, Delta Electronics Foundation and other public and private organizations, the Min Chuang Elementary School was rebuilt into the first Net-Zero Energy Campus of the R.O.C.
The new Min Chuang Elementary School is designed to weather extreme natural conditions and double as a disaster command center for the region during storms. Metal framework from the Ring of Celestial Bliss plays a big part as steel foundations for the school’s rooftop solar panels. Over 59 tons of metal are reused in the construction of the school and its related green energy infrastructure. The current installed solar capacity at the school is 40kW. It is expected that the renewable energy generated on-site would balance out the energy consumed by the school and eventually reach Net-Zero Energy Campus status.

In addition to donating the steel framework to disaster stricken school districts, other materials from the Ring were redistributed for other uses. The bamboo façade was dismantled and given to the Earth Passenger Environment Workshop, an organization devoted to sustainable design and environmental education, for the construction of a classroom. The projection screen canvas was recycled and manufactured into eco-friendly canvas bags. The LED lights used in the Ring were given to the National Museum of Natural Science in Taichung as a beautiful energy saving light sculpture.
The LED light sculpture adorns the 8-story tall façade of the museum’s rainforest greenhouse. 234 sets of LED lights form the theme of “Magical Rainforest – Four Seasons Symphony”. The light display tells the story of biodiversity and environment sustainability of rainforests, promoting the concept of nature conservation while serving as a brilliant decoration for the community. Due to the use of efficient LED bulbs, the electricity cost is on USD$ 1.2 per day. The light show gives the greenhouse a new life at night, turning it into a new landmark in Taichung City area. It also gives an impactful performance with brilliant lights and symphonic music, leaving a deep impression in the hearts of its audience, reminding them of the importance of green technology and environment preservation.
