A seminar on conditions for conservation of cultural properties: Controlling and Predicting Conditions for Conservation of Cultural Properties
For the conservation of cultural properties, it is important to maintain properly environmental conditions such as temperature, humidity, light, and air quality. Environmental conditions of temperature and humidity in facilities that exhibit and store cultural properties have been improved remarkably with the progress of technology of air-conditioning units. On the other hand, from the viewpoint of the change of climate conditions surrounding cultural properties on loan transported between regions of different climates and of the energy saving, the debates for discussing temperature and humidity conditions is recently being held more and more actively not only in Japan but also internationally.
The Center for Conservation Science and Restoration Techniques studies how the influence of temperature and humidity on cultural properties and methods to predict and control temperature and humidity levels. A seminar on Controlling and Predicting Conditions for Conservation of Cultural Properties was held on February 9, 2015. Researchers in conservation (MABUCHI Hajime of the Mie Prefectural Museum and KOTAJIMA Tomoko of the Tokyo University of the Arts) and experts in architecture (GONDO Takashi of the Kajima Technical Research Institute, KITAHARA Hiroyuki of Total System Laboratory Co., and ABUKU Masaru of Kinki University) were invited to do presentations at the seminar. The latest information on conditions for conservation of cultural properties was shared and discussed at the seminar. This information included examples of temperature and humidity control with air-conditioning units in museums, examples of the new systems that have been developed and installed, examples of studies of temperature and humidity levels and air quality in display cases, and comparisons of the measured temperature and humidity levels and those predicted by using computer simulations (attendance: 29 individuals).
