Infrared building inspection with unmanned aerial vehicles.

Abstract

Article discusses the subject of energy efficiency in the construction and building sector and the use of unmanned aerial vehicles in order to study energy consumption in buildings. At the beginning, the concept of energy efficiency in buildings is presented, its importance and impact on the environment. Then, the article discusses the current situation, the trends in Europe and the potentials of this sector together with the most important legal issues related to the topic of energy efficiency. The next section explores the effects of buildings on the environment, in particular, through heat loss. The article also outlines the importance of research methods and thermal imaging. Specifically developed unmanned aircraft classification is adapted for the use in thermal studies. The topic is discussed in terms of both the characteristics and structure, as well as the advantages and disadvantages of the use of such solutions. Possible paths of development in this subject are presented, as well as problems and concerns. The last part focuses on the example of the use of unmanned platform to study thermal imaging of a residential building. This is a case study carried out in December 2014.

Power sources involving ~ 300W PEMFC fuel cell stacks cooled by different media

“…By replacing their batteries either partially or totally with a fuel cell system, flight times can be significantly extended [17].…”

Implementación de un prototipo para captura y procesamiento digital de imágenes térmicas adquiridas desde un UAV

“…1 -11 de casos tienen el limitante de solo poder adquirir imágenes de forma manual. Es necesario mencionar también que hasta hace pocos años se plantearon nuevos enfoques en el uso de cámaras térmicas como la portabilidad en UAVs, esto se manifiesta por ejemplo en operaciones tales como la inspección del aislamiento en edificios (Zhang, et al, 2015), (Krawczyk, et al, 2015) o en el seguimiento de objetos (Albrigtsen, 2016).…”

Parameters selection of extended-range electric vehicle supplied with alternative fuel

“…The difference lies mainly in the capacity of energy storage (greater than in hybrid drives, but smaller than in electric drives) and in the method of controlling the power flow in the system [15]. The use of a small combustion engine allows a significant extension of the EREV driving range in relation to pure electric cars and at the same time the size of the electric energy accumulator is reduced and the current load is lowered, which significantly affects the lifetime of the electrochemical battery.…”
