Energy survey of a historical building by infrared thermography

Energy surveys in buildings are now a usual practice for recently built constructions, as the energy management is currently becoming a crucial issue. Also historical buildings are demanding attention from an energetic standpoint, as the most part of them needs renovation interventions. Due to their peculiar characteristics, these kind of buildings require advanced, non-invasive and non- intrusive survey techniques such as infrared thermography. In this paper the ancient church of San Vito alla Rivera, located in L'Aquila, has been inspected with infrared thermography. Data obtained from the survey have been used to improve the reliability of numerical energy simulation software, as energy modelling can support and orient the renovation process of the building.
