ABSTRACT
ABSTRACT: This paper presents work developed on moisture-related decay in San Juan Bautista Church (12th-13th Century) at Talamanca de Jarama, Madrid, Spain. This church shows a complex building history due to various constructions and remodeling stages, which affected water ingress in the walls. Moisture dynamics are also influenced by a forced air localized heating system which alters microclimatic conditions. Moisture distribution of selected areas of the walls, which were chosen based on their state of decay and the influence of the heating system on them, was monitored. Sensing techniques included wireless sensor networks, electrical resistance tomography, thermography and portable moisture meters. Outdoors, indoors and internal temperature and relative humidity of the walls at different depths were monitored. This work includes a comparative study of thermography and electrical resistance tomography to characterize thermal and hygrometric behavior of the most affected wall.
