Tecnologías digitales para el análisis de edificios. Salud, confort y energía = Digital technologies for building analysis. Health, confort and energy

Abstract

The digitization of the building sector has become one of the keys in this area because it improves workflows and thereforeimproves its competitiveness. However, digitization per se is an important challenge that at an operational level is difficult to implementdue to the multiple obstacles we face on a day-to-day basis. Therefore, organizations must follow the strategy that best suits their needs and that allows distinguishing those tools that really help them to facilitate their work. This research focuses on the conclusions obtainedfrom the real application of various digital technologies during the energy analysis carried out for the Hernani City Council (Gipuzkoa).For both case studies analysed, the Town Hall itself and the House of Culture of Biteri, the digital technologies that best adapted to thework were implemented. These included hygrothermal monitoring with the own developed devices by 3D printing, Open SourcePlatforms (OSP Open Source Platforms) and the Internet of Things (IoT), the evaluation of the thermal envelope using infraredthermography, heat flow metering and blower door test, the generation of a historic building's digital twin with the BIM methodology,and the evaluation of comfort and energy demand of different intervention measures using dynamic software for the energy simulationof buildings. From the work carried out, it is concluded that the tools used have facilitated the tasks assigned to evaluate the currentperformance and the proposals for the refurbishment of the buildings under study. However, it has also been detected that highequipment acquisition costs, the need for very specific training or very restrictive current regulations can pose significant obstacles thathinder the implementation of these technologies. Therefore, as one of the current objectives is the implementation of digital tools,establishing the required routes for this purpose becomes a priority for the building sector.
