Abstract
This article aims to properly assess the hygrothermal properties of walls located in historic buildings, this study discloses the development of a remote sensing technology compatible with an in-situ measurement implemented in Palazzo Tassoni (Italy). As required by the international recommendations adapted to cultural heritage (CH), this monitoring system balances CH conservation, performance aspects and economic costs using an integrated multidisciplinary approach. Electronics for measurement of environmental parameters is composed of sensor measurements, data acquisition system and data storage and communication system. Data acquisition system, equipped with standard modbus-rtu interface, is designed to run standalone and it is based on two cloned single board PCs to reduce the possibility of data loss. In order to reduce the costs, RaspberryPI single board PCs were chosen. These run a C/C++ software based on standard modbus library and designed to implement multi-client server TCP/IP to allow communication with other devices. Storage and communication systems are based on an industrial PC; it communicates with sensor measurements’ system through a modbus-TCPIP bridge. PC runs a Labview software to provide data storage on a local database and graphical user interface to properly see all acquired data. Herein, some sensing options and approaches of measurement are described, unveiling different possible ways of enhancing the retrofit of CH with adapted technology.
Highlights
The objective of the present study is to present the development of a compatible, low cost and high accurate conservation remote sensing technology for the hygrothermal assessment of historic walls before and after the retrofit intervention to solve the above-mentioned issues, bridging the fields of electronics, building science and cultural heritage (CH) conservation
Sensors: Selected sensors were from 40% to 80% cheaper than similar sensors; ADC devices: Selected devices are cheaper from 10% to 15% compared with similar low accuracy devices and up than 60% compared with high accuracy systems;
This paper proposes an in-situ hygrothermal remote sensing technology for historic buildings
Summary
“Cultural heritage” (CH), termed “cultural property”, “cultural patrimony” or “cultural resources”, can be defined as the present manifestation of the human past. IRT survey is based on the use of an infrared (IR) imaging camera that operates in short (3–5 μm) and long (7–14 μm) wave IR-bands [14] for measuring the distribution of the emissive power of surfaces at various temperature range [14,15,16] It permits the assessment of the thermal anomalies related to structural features, building materials, moisture contents, and hygrothermal behavior of building elements [17,18,19], as well as in high-temperature inspections (i.e., industrial process, HVAC (heating, ventilation, and air-conditioning system), and electrical systems) [16].
