“…The simulation results described hereinafter are referred only to the nave, since it preserves the cultural heritage and it will be frequented by occupants, although they can also be extended to the sacristy. With regard to the analysis of thermal comfort, it was carried out on the basis of similar works already published in the literature [1,26,27], in which thermo-hygrometric threshold values, such as to ensure wellbeing for the occupants, were set. In particular, temperature values between 20 °C ± 2 °C in winter season, 26 °C ± 2 °C during summer, and relative humidity in the range 50% ± 10% were set in this work to perform the thermal comfort analysis [46].…”

“…Thanks to dynamic simulation modeling, the work concludes that the sole hypothesis of passive interventions does not guarantee the complete elimination of mechanical risks and biodeterioration of movable heritage, but this result can be achieved with a combination of passive and active actions. Aste et al [27] discussed the opportunity to provide the Basilica of Collemaggio in L'Aquila (Italy), also subject to restoration following the 2009 earthquake, with a hydronic pew-based heating system. In their work, the calibrated CFD simulation is employed as a performance analysis tool of the chosen heating system, which is based on a local-comfort strategy.…”

Indoor microclimate and energy performance analyses of historic buildings require tailored methodologies, because of their complexities, e.g. presence of artworks, lack of documents or project data and employed structure and materials. Given such difficulties, there are a few interdisciplinary methodologies, capable of carrying out multi-objective analyses for this kind of buildings, and they are often based on in-situ monitoring that, however, may not be able to predict the effects deriving from different conceivable technologies and control strategies. In this work, an interdisciplinary methodology is employed for evaluating cultural heritage conservation conditions, occupants 'thermal comfort and energy performance of a specific historic building category, such as churches, on the basis of experimental and numerical approach. The methodology was applied to the case study of an ancient Italian church, recently restored following the earthquake that hit L'Aquila in 2009. After the refurbishment of the church, the statistical analysis of temperature and relative humidity experimental data allowed to observe that the conservation conditions of artistic heritage just restored may be non-correct, due to remarkable thermo-hygrometric fluctuations of the indoor microclimate. Therefore, starting from the current condition of absence of HVAC system, calibrated dynamic simulation models of the church allowed to hypothesize different technological solutions able to control the indoor microclimate and to evaluate the effects on artworks preservation, thermal comfort, and energy performance. The results of the multi-scenario analysis showed that suitable conservation conditions (PIs > 90%) and thermal comfort can be obtained by employing a complex heating/cooling and humidification/dehumidification system which determines a significant increase in energy consumption.

“…Implementation of other solutions, like a new heating system might require extensive intervention in the existing construction, including new heat distribution ducts that may be complicated or not possible to deploy due to limited space [84]. For this reason, some studies promote heating through small pipes mounted in or on the inside of the walls [85], or floor carpet heating systems aiming at reducing the spatial and material impact on heritage buildings [86].…”

Conservation-Compatible Retrofit Solutions in Historic Buildings: An Integrated Approach

Historic, listed, or unlisted, buildings account for 30% of the European building stock. Since they are complex systems of cultural, architectural, and identity value, they need particular attention to ensure that they are preserved, used, and managed over time in a sustainable way. This implies a demand for retrofit solutions able to improve indoor thermal conditions while reducing the use of energy sources and preserving the heritage significance. Often, however, the choice and implementation of retrofit solutions in historic buildings is limited by socio-technical barriers (regulations, lack of knowledge on the hygrothermal behaviour of built heritage, economic viability, etc.). This paper presents the approach devised in the IEA-SHC Task 59 project (Renovating Historic Buildings Towards Zero Energy) to support decision makers in selecting retrofit solutions, in accordance with the provision of the EN 16883:2017 standard. In particular, the method followed by the project partners to gather and assess compatible solutions for historic buildings retrofitting is presented. It focuses on best practices for walls, windows, HVAC systems, and solar technologies. This work demonstrates that well-balanced retrofit solutions can exist and can be evaluated case-by-case through detailed assessment criteria. As a main result, the paper encourages decision makers to opt for tailored energy retrofit to solve the conflict between conservation and energy performance requirements.

“…Temperature has been simulated as a concern for materials, such a church organ preservation [27], but also for human comfort [9]. Temperature is the key parameter in the design of sustainable heating strategies that minimise energy consumption while obtaining appropriate conditions, for objects and for occupants [43,54]. The simulations of temperature often aim at obtaining a homogeneous environment (i.e.…”

Fluid simulations in heritage science

This review addresses the use of computational fluid dynamics for the interpretation and preservation of heritage. Fluid dynamic simulations in the heritage field focus mostly on slow air movement in indoor spaces and they usually involve temperature and humidity. Simulations have different roles: they may be exploratory, they may be used to support preventive conservation and occasionally they aid historical or archaeological interpretation. The research questions rarely involve testing or development of new mathematical formulations; instead, existing computational models are used as a means to help solve practical issues. Computationally, the simulations are typically steady-state and they always use a turbulence model. Experimental validations against measured data are uncommon and there is a need for the production of benchmarking cases and the publication of experimental data. Further research is needed in order to explore suitable approximations to the simulation of change in the timescale of months or years, low turbulence flows for which current mainstream turbulence models are ill-suited, and new mathematical formulations for near-wall transport phenomena.
