歷史建築再利用計畫之物理環境評估方法研擬

Development of Physical Environment Evaluation Method for the Reuse of Historical Building

摘要


歷史建築再利用的目的主要為保存環境資源及文化資產,並考量再利用建築之文化、歷史、藝術、科學及實用面向,根據台灣現況,大多再利用計畫多以展示空間規劃為方向,故科學性及實用性對空間實質環境規劃上具有相當之影響,但實際現況科學性與實用性與其他面向比較卻較容易忽略,所以當同再利用計畫落實於實質空間環境時,多藉由設備手段創造室內舒適性,因此增加管理維護成本,但現今再利用計畫較少對實質環境之物理條件進行評估,亦即再利用目的適宜性評估中科學之評估較不受到重視,故研究目的為透過歷史建築室內環境診斷,結合氣候資料討論以再利用為展示空間之適宜性,期望以被動式設計方法達成再利用之目的,本研究以桃園縣八德市中正堂做為標的,進行空間之熱、風及光環境量測,將所測得之數據轉成無因次數值,並以展品保存及人體舒適之兩項標準進行比較,比較分析現有空間再利用之環境問題並提出改善對策,透過此實驗方法反流程,歷史建築再利用室之物理環境評估方法可因此建立,做為建築再利用適宜性評估之參考依據。部分研究結果可知中正堂在熱環境分析中,所測得空氣溫度位於人體舒適範圍內,而各區測得濕度則是偏高,故熱環境所要改善問題為降低各區之濕度,但做為展示空間使用時,則需要降低溫度與濕度。而本研究選擇自然通風的方式,增加空氣流動降低室內濕度以達人體舒適環境,但欲達展品理想環境,則需消耗大量能源,且造成人體舒適度降低。因此,將展品放入展示櫃中,並採取間接照明方式,避免自然光直接照射,提供24小時的溫、溼度控制,如此在人體舒適環境及展品理想環境均能達成平衡,並可節省能源的消耗。

The main purpose of reusing historic buildings is to preserve environmental resources and cultural properties on cultural, historical, art, and scientific aspects. Considering current situation in Taiwan, most reuse projects are based on displaying the spatial planning; therefore, scientificity and practicability are crucial on spatial environmental planning. Yet in practical situation the scientificity and practicability are easily neglected. Thus, while applying reuse project on virtual environment, equipments, which results in rising maintaining costs, are largely used for creating indoor comfort ability. Given the fact that current reuse projects have less consider at ion on physical conditions of virtual environment and meanwhile the scientific assessment is also neglected during examining the suitability of the reuse projects, this study emphasizes on the suitability of reusing historic buildings as exhibition apace through the indoor environment diagnosis and climate data examination. Setting Chung Cheng Hall, which is located in Ba-De City, Taoyuan County, as the research object, this study is expected to achieve reuse purpose by passive design methods. Performing measurements on the heat, wind, and luminous environment and transmitting the data into dimensionless values are included in this study along with the comparison between the preservation of the exhibited items and the human body comfort. By analyzing current issues of the environment for reuse and proposing improvements through the experimental method and process in this study, the physical environment assessment of reusing historic buildings can be established as a reference for suitability assessment of architectural reuse. Part of results in this study shows that in the thermal environment analysis of Chung Cheng Hall , the measured air temperature is in the human body comfort zone while the humidity measure d in each area is slightly higher than average. Therefore, improvements should be made to lower the humidity of each area and in advance, both the temperature and the humidity should be attenuated while the environment is in use of the exhibition space. In this study, the natural ventilation is put in use to achieve a comfortable environment for human body by increasing the air flow rate to attenuate the indoor humidity. But to accomplish an ideal environment for exhibited item, large amount of energy is needed and which again lowers the human body comfort level. As a result, by putting the exhibited items in the display cabinets with indirect lighting, avoiding direct natural lights, and a 24-hour temperature and humidity controlling, both the human body comfort environment and the ideal exhibition environment can be accomplished and the purpose of energy-saving is also achieved.
