This report is the thesis of the research and development project entitled: Development of a Resource Saving Concept for the Establishment of a Climate Suitable for the Storage of Objects Worthy
of Preservation in Storerooms at Museums and in Archives.
In short: The ZEPHYR project.

This work is the result of a research and development project. The aim is to improve the possibilities of using passive climate control for museum, archive and library repositories. Passive climate control implies that the repository is built and arranged so the thermal and hygroscopic properties of the building and its contents creates a good stable indoor climate. Passive climate control also ensures that the temperature and relative humidity stay within the acceptable ranges. It is an alternative to the traditional mechanical climate control with humidifiers, dehumidifiers and cooling and heating installations controlled by complex control and adjustment technology. The mechanical method has been used since the late fifties, from time to time with varying degrees of success. The knowledge of the thermal and hygroscopic interaction between a building and its contents, influenced by a certain local climate, is further developed in this project. Therefore, theoretical studies and measurements carried out at the Regional Archive of Schleswig-Holstein, which is passive climate controlled, are completed. On this basis a calculation model has been developed, which makes it possible to do parameter studies of the climatic influence of the building structures and the building material. The results of the measurements are used to compare the theoretical performance of the building with the actual performance. Taking the operational conditions into consideration, the building can be designed to be the framework of a stable storage environment at low operating costs and a minimal energy consumption. A new constant is defined: The Buffering Capacity Factor. It is a factor that defines materials capabilities in buffering (stabilizing indoor climate) thermal or humidity variations. Due to this, the principles of the ZEPHYR Climate Controlled Repositories is introduced and so is the concept Sustainable Storage.
