Contemporary methods of determining energy losses in structures

Abstract

The paper points at the importance of determining energy losses in construction objects for the purpose of remedying problems of energy loss and issuing energetic passports. Two contemporary methods for the collection of information based on the principles of thermography are presented. The first method refers to the application of a remote sensing system that includes sensors from the infrared part of the electromagnetic spectrum. The second method uses LIDAR technology to collect point cloud data and thermal images from a moving vehicle. This data not only permits the construction of 3D models of urban environments, but also, in combination with thermal recordings, provides the basis for an analysis of a large number of structures, their thermal properties and a significant energy resource for the issuance of energetic passports.
