The Influence of External Climate on Church Internal Microclimate

Original language description

The paper deals with monitoring microclimate in a church and describes the influence of exterior microclimate on interior microclimate, and its changes during one year. The basic parameters of the interior space (temperature, relative humidity, dew point, and specific air humidity) were long-term monitored in the selected sacral building along with monitoring exterior surroundings. Monitoring of the internal microclimate of the ossuary showed significant instability of the interior environment during the annual cycle, where the appropriate limits of humidity of the environment were significantly exceeded. The behavior of the microclimate in the ossuary also differs in heigh levels, where the lower space acts as a pool with heavy cold air and vice versa, the space under the vault is moistened with vapor. The fact that in no circumstances of the exterior climate in winter is the temperature of the interior below the freezing point is specific. In certain periods, optimal conditions for water condensation on the wall surfaces and equipment of the ossuary arose enabling the development of mold in the internal environment of the ossuary. Monitoring of the internal microclimate of ossuary during everyday operation became the basis for the subsequent design of the reconstruction of the building. The remediation proposal must address several issues at once, namely to reduce moisture in the walls of the building, restore original materials while maximizing their preservation, stabilizing the internal microclimate in terms of humidity, creating optimum conditions for the natural drying of residual structural moisture, and ensuring the mode of future operation with minimum changes in the internal microclimate. Due to the historical value of the building and its layout, it is possible to use forced air treatment only to a limited extent, by using the natural physical properties of air and phenomena involving its natural flow and controlled temperature exchange between spaces.
