LEED BD+C: New Construction v3 - LEED 2009
AUO TFT/LCD Fab L8B
LEED Platinum 2011
A green facility in central Taiwan science park seeking the balance between sustainability and development.
Site development for a new generation high-tech plant project often affects tens of hectares of land. The planning and construction process is almost always accompanied by environmental protection issues and concerns raised by neighboring residents. AU Optronics (AUO), a flat panel display and solar system integration manufacturer, is a company that believes a sustainable environment is just as important as industrial development. They are committed to not only pursuing innovative designs and advanced technology but also to upholding corporate social responsibility and sustainable business philosophies. In 2008, AUO announced that all future facilities would be LEED certified, focusing on sustainability and energy saving designs. AUO has several LEED certified projects resulting from this commitment, including L8B Fab in the Central Taiwan Science Park- Houli site, which earned a Platinum level certification.
AUO worked diligently in the early planning stages for the L8B Fab to maintain the integrity of the site. Experts and scholars were hired to evaluate the potential environmental impact and develop countermeasures as well as identify opportunities to reduce energy use. The company also took the initiative to retain a large green open space and planted trees to reduce the effect on the existing ecological environment.
Through this process, AUO found that the energy performance of buildings can be improved when the local climate, building shell and clean room environment are considered comprehensively. During the design process, AUO used energy simulation software to evaluate building performance. Taking the characteristics of the local climate into account, AUO found that constantly controlling the temperature and humidity of clean room environments used excessive amounts of energy. By downgrading the wall insulation specifications, the outdoor temperature could help maintain the low target temperature of clean rooms in the winter without additional help from HVAC equipment, thus saving on the initial construction cost as well as ongoing energy costs. The final design of the building shell assembly was a combination of external insulation and required clean room temperature. This result also gave the owner an example of how design coordination can result in extra energy saving opportunities. A higher performing building insulation system does not always guarantee the best energy performance for the entire building system.
About AU Optronics Corporation
AUO was formed in September 2001 by the merger of Acer Display Technology, Inc. (the former of AUO, established in 1996) and Unipac Optoelectronics Corporation. In October 2006, AUO acquired Quanta Display Inc. AUO has thus been operating production lines of various generations, capable of offering TFT-LCD panels from small to large sizes. AUO was also the first pure TFT-LCD manufacturer to have been successfully listed at the New York Stock Exchange (NYSE). AUO extended its market to the green energy industry in 2008 to provide customers with high efficiency solar solutions.
