Dong lin Monastery (East Forest Monastery) is seated at the northwestern foot of Mt. Lushan, about 16 km (10 miles) from Jiujiang City, Jiangxi Province. It was initially built in 384 A.D. in the Eastern Jin Dynasty (317-420) and developed in popularity through the Tang Dynasty (618 -907). Later it suffered a lot of damage and has been renovated in recent years. Now, it receives a great many Buddhist disciples and visitors every day. The building uses a large number of wooden structures, poor thermal insulation performance, many doors and windows and large gaps, and serious air leakage. More importantly, the terminal system layout cannot affect the decorative style and cultural requirements of the temple.
