周邊環境延燒因子對歷史建築之影響－以迪化街為例

由於近年來多處重要古蹟、歷史建築發生火災，使得台灣逐年提升對於文化資產的建築防災概念，然而這些規劃往往僅止於單棟建築防災，忽略了周遭環境的延燒因子，亦會使建築身陷危害中。迪化街街區內擁有許多歷史建築，這些歷史建築經由嚴格的用火限制、本身用途的改變或已閒置多年，因此自燃風險偏低，卻因周邊建築使用用途可能屬於高火載建築，導致歷史建築延燒風險增加。本研究以兩棟位於迪化街不同街段的歷史建築，對其周邊環境延燒因子加以分析研究，以此得出結論。一、以迪化街區內兩棟歷史建築為例：（一）迪化街一段155號的歷史建築，位處該區中北街段，由於對面為金紙店舖及免洗用具雜貨店，且相鄰鐵皮屋，皆屬於高火載用途建築，使歷史建築雖然本身雖無火載量，卻由於周邊環境，導致歷史建築有高延燒風險。（二）迪化街一段56號的歷史建築，位處該區南街段，由於周邊建築用途皆為中藥鋪，屬於低火載用途建築，且對面為永樂市場廣場，擁有較大避難空間，使該歷史建築無高延燒風險。

Due to fires in many important monuments and historical buildings in recent years. Taiwan has been improving the concept of building disaster prevention for cultural assets year by year. However, these plans are often limited to the disaster prevention of single buildings, ignoring the prolonged burning factor of the surrounding environment. It also puts the building in danger. There are many historical buildings in the district of Dihua Street. These historical buildings have undergone strict fire restrictions. Their use has been changed or have been idle for many years. Therefore, the risk of spontaneous combustion is low. However, the use of surrounding buildings may be high-fire buildings, which increases the risk of burning historical buildings. This study uses two historical buildings located in different sections of Dihua Street. Analyze and study the prolonged burning factors of its surrounding environment to draw conclusions. 1. take two historical buildings in Dihua District as an example: 1. The historic building at No. 155, Section 1, Dihua Street, is located in the middle and north Street section of the district. Because the opposite is incense shop and the grocery store, and illegal light gauge steel roof construction are all buildings with high fire load. Putting historical buildings at high risk of burning. 2. The historical building at No. 56, Dihua Street, Section 1, is located in the south section of the district. Because the surrounding areas are all buildings with low fire load. And the opposite is Yongle Market Square. So the historical building has no risk of high fever.
