Thermographic and mobile indoor mapping for the computation of energy losses in buildings

Abstract

A mobile indoor mapping system combined with infrared thermography was used for the acquisition of data needed for the quantification of heat loss through a building envelope by conduction; that is, temperature values and building geometry. The methodology presented orthothermograms to provide measurement of heat loss and thermographic images with geometric information. This way, not only the energy loss through the building envelope is provided, but also thermographic information regarding the existence of thermal pathologies, their location and their impact on the building can also be evaluated.
