“…The 16th and 17th century churches of the Czech Republic use heating elements that are placed among the benches during the cold seasons and which are switched on for the worship, only thus ensuring local intermittent heating. These have average indoor temperatures of 16.7 • C and lowest indoor temperatures of 1.1 • C [15]. Huge differences in air parameters in one room accelerate the deterioration of materials [16].…”

The microclimate plays a crucial role in the conservation of historical cult buildings and their artifacts for future generations. In order to conserve these buildings and their artifacts, it is imperative to ensure that the microclimate is conserved. The norms and standards existing so far in Latvia do not stipulate thresholds for air parameters that would ensure a conserving microclimate for historical cult buildings. In order to identify these thresholds, the air parameters were measured simultaneously at nine measuring points within the Krimulda Church (LV) of the 13th century. The temperatures of the surfaces of the building envelope and potential condensation were calculated using the actual data of indoor and outside air. The indoor and outdoor air humidity ratio was calculated for each measurement. The conservation threshold of indoor microclimate parameters was determined by using intermittent heating on the basis of the air parameter fluctuations and calculations. The moisture vapours from the building structures were quantified in this research. The indoor humidity ratio during the warm season and the upper threshold during the heating season were determined.

“…Hnilica et al [47] proposed establishing the historic indoor climate as a suitable method of assessing historic buildings. Understanding the historic climate within the church is a method for understanding the climatic variations the artefact has endured over its lifetime in that space.…”

“…An alternative method of establishing a suitable indoor climate for artefacts is to use the target range method described by Hnilica et al [47]. Through the identification of the artefacts present within the historic church environment, the temperature and relative humidity range can be established using tables of data, such as those presented in Figure 2.…”

Historic Churches and Their Hygrothermal Environment: A Review of Criteria Related to Building Fabric, Artefacts, Artwork and Occupants

Regarded as important cultural heritage, historic churches have been utilised over hundreds of years for worship and community benefit. Simple on/off space heating systems are installed in many churches to increase human comfort. However, the conservation of the important historic artefacts and artwork contained within may not have been fully considered. This review attempts to appraise the standards in place for artefacts and artwork. A consensus of 15–25 °C and 40–65% relative humidity is established as safe from the standards reviewed. Consideration is given to the environment within the church to understand if such exacting conditions can be met. The review finds that the conservation and preservation of artefacts and buildings are aligned goals, although striving to meet specified target ranges for artefact types is not fully compatible with historic churches. The stability of the internal environment is clearly an important factor in conservation and benefits human comfort expectations. Churches may contain microclimates throughout the building, complicating the use of target ranges for artefacts, artwork and comfort. The findings of this study can assist historic churches in managing the change, alteration or installation of heating systems.

“…Suitable climatic conditions in the attic space can have a positive effect on the service life of the structure. These conditions are mainly influenced by the attic ventilation and external weather conditions [1][2][3][4][5]. In addition to the wind and the temperature difference, the airflow during the attic ventilation is also affected by the solar radiation absorbed by the roofing, when the heated roofing increases the air circulation [6,7].…”

Simulations of Airflow in the Roof Space of a Gothic Sanctuary Using CFD Models

et al. 2021

For a deep understanding of the airflow in an environment of historic wooden trusses, it is necessary to analyze the object using simulation methods. To calculate the amount of air passing through the structural openings (components) using dynamic simulation, multi-zone network models based on the simplicity of modeling the individual zones are suitable. For a more detailed analysis of airflow and temperature distribution within one space, a computational fluid dynamics (CFD) simulation model was performed. The air volume through openings and surface temperatures was adopted from the multi-zone airflow network model. By using this simulation technique during a sunny summer day four characteristic states of air movement were simulated in the attic: more intense flow at noon and at midnight caused by a large temperature difference between air and surrounding surfaces and, subsequently, less intense flow when the air was mixed up effectively. The temperature distribution in the cross-sections did not only indicate an increase in temperature with increasing height (up to 50 °C at noon) but also a temperature increase near the southern roof. The surface temperature of the masonry walls was stable (19–33 °C), while the air temperature fluctuated. The image of the flow was completed by ventilation through the tower, which acted as a solar chimney. The airflow through the door to the tower was almost 0.5 m3 s−1 at summer midnight.
