“…Attempting to minimise short-term fluctuations in temperature and RH is key to artefact conservation. When RH drops during comfort boost heating events, hygroscopic materials begin to give up moisture in response to the lowered RH [35]. boost heating events, hygroscopic materials begin to give up moisture in response to the lowered RH [35].…”

“…The National Trust, which uses conservation heating extensively across its portfolio of properties, has focused attention on training house staff and conservators on the operation of conservation heating strategies. Humidistat-governed heating systems are only effective if staff understand the principles and techniques required to operate them [35]. One of the major drawbacks when trying to apply the principles of conservation heating to historic churches is the lack of thermal comfort that could result during high and low temperatures in summer and winter, respectively.…”

“…The desire to control relative humidity and the resulting damage to artefacts and building fabrics prompted the concept and application of conservation heating in National Trust properties. Historic properties normally experience relative humidity levels between 60-80% [35], which is above the maximum that many artefacts can tolerate for long periods without experiencing degradation. Over time, the tolerance and range has been adjusted due to the financial implications of providing heating to larger properties and a greater understanding of the behaviour of artefacts with the duration and range of fluctuations in relative humidity.…”

“…Therefore, the proposal to limit room temperature to 22 • C in summer and allow the RH to increase has been the National Trust policy since 1994. However, with climate change, the percentage of time that RH control is lost in a calendar year has increased [35].…”

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.

This research addresses the issue of the heritage preventive conservation in the perspective of energy sustainability, for contributing to the achievement of the Sustainable Development Goals (SDGs) and towards the EU Green Deal. The study analyses and compares four cases associated with different microclimate thresholds as suggested by the standard EN 16893:2018 (Cases 1–3) and as derived from the outputs of three degradation models for preserving paper, wood, and canvas paintings (Case 4). Weather-based indices (degree and gram days) were calculated to estimate trends in the potential energy demand of collection facilities in three European cities belonging to different Köppen-Geiger climate zones (Cfb, Csa, and Dfb), under recent past (1981–2010) and near/far future climate scenarios (2021–2050 and 2071–2100) from two Shared Socioeconomic Pathways (SSP2-4.5 and SSP5-8.5). The findings suggest that adapting facilities’ management strategies to focus on collections preservation can facilitate the achievement of 5 out of 17 SDGs, offering a viable alternative to costly energy retrofits and encouraging the development of shared solutions for similar facilities in the same climate zone. The results can contribute to inform the revision of EN 16893 and to face major challenges such as the preservation of paper collections in southern latitudes.
