節能政策下有關國家檔案庫房溫溼度環境控制之探討

Environmental Control System of Temperature and Humidity under the Energy Saving Policy in National Archives Repository

為因應能源成本日益高漲，國家檔案庫房除妥適的溫溼度環境外，更應是具有低耗能的性能。本文經回顧相關文獻，得到檔案保存溫溼度環境需求為：相對溼度不可高於60%；溫度與相對溼度越低越好，但仍應依檔案媒體性質而定，且變動程度必須在該媒體可容忍的範圍內。在不影響檔案預期保存期限下，可依地區氣候季節特性將檔案庫房溫溼度環境設定點作適當變動，以達省能。由國內外各檔案庫房溫溼度環境控制案例得知，檔案庫房若能善用被動式氣候控制技術，以採用具有低熱傳透率、高熱容與低溼滲透率特性之建築外殼，以及庫房有高度的氣密性與使用高效率空調系統等作法，可使庫房達成低耗能的性能需求。

To save the cost of energy consuming, the National Archives repository not only has to keep appropriate temperature and humidity, but also in low-power performance. According to literature review in this study, rathe the requirements of which include: relative humidity should not be higher than 60%; temperature and relative humidity should depend on the characteristics of stored archives and media of which endurable range to adjust as low as possible. In order not to affect expected lifetimes of collections, the temperature and humidity should be set appropriately by the change of local climate and seasonal characters for energy saving. From previous studies, we discovered that if repository can use of passive climate control technologies, and low heat transfer through rate, high thermal capacity, low moisture permeability characteristics of the building envelope, a high degree of air tightness and high efficiency air conditioning system, and etc., so that the repository will satisfy the requirements of low energy performance.
