“The role of climate in Museum Buildings. Albanian Case Studies” Bushati, E., Vice Dean of Faculty of Architecture and Urbanism Abstract Museums are housed in buildings designed for museum but often they are housed in buildings which are not designed and build for this purpose. These two main museum building typologies can fulfill different indoor climates for artefacts preservation. Seeing in this complexion, the building is a buffer volume which plays the main role in mitigating the external climate. Building design, construction and the building technologies affects building performance and as a result the indoor climate. For the preservation of the artefacts in a museum the indoor climate is often restricted to a narrow interval for temperature, but most of all for relative humidity. These standards for temperature and relative humidity, however, does not fit well in some museum buildings. For this reason, today’s museum standards for artefacts preservation must be verified and evaluated based on real site measurements. The monitored parameters should be interpreted starting initially from the building design, building materials and building technology.For some typical Albanian museums case studies have been done to show how the physical building effects the museum climate. Three well known Albanian museums are selected to be examined; The National Historic Museum, the Archeological Museum of Tirana and the Iconographic Museum “Onufri” of Berat. The three examined museum buildings represent different museum building typologies as well as different construction technologies. The National Historic Museum is a building designed to be a museum and is one of the most representative buildings of this typologies. It is constructed in 1981 and the construction technologies are considered as advanced for the period. The Archeological Museum and the Iconographic Museum “Onufri” represent the museum buildings that are not build for this purpose but are used as museum buildings. The Archeological Museum is housed in a building designed by Italian architect G.Bosio in 1939 embodying the construction technologies of the period when it was built. The Iconographic Museum “Onufri” is housed in the Saint Mary church that is the most representative church of Albanian post-Byzantine architecture. It is constructed in 1797.Buildings are analyzed in a methodological way. The process of selecting buildings is based on well-defined criteria. The monitored buildings should represent different museum typologies, were built in different periods, were identified as problematic during the site visits and also is taken into consideration the cultural, social and economic importance of the selected buildings in the Albanian museums network.For a measurement period, at least one year, are done records of Temperature and Relative Humidity in different indoor environments of the three mentioned above buildings. The measurements are done in a narrow frequency (each 15 minutes) with electronic data loggers. The values and the results compared between the three buildings. Analyses of thermo hygrometric parameters (T and LR) showed that there is a contrast among indoor climates of these buildings. Each building appears with its own indoor climatic characteristics, depending on the type of building, construction characteristics and the level of building degradation.   The study interprets the data after it is analyzed the construction technology for each building and proposes the strategy to improve the preservation conditions.Key words: Museum building, building technology, temperature, relative humidity, preservation
