IoT-based architecture for efficient energy monitoring in existing building structures

Abstract Considering the definition of Environmental, Social and Governance (ESG) criteria, historical buildings in Europe need solutions to be able more energy efficient. One approach identify high consumers is data analysis. To enable this approach, following research questions have answered: 1. How can captured a valid efficient way? 2. standardized merged within dashboards? 3. analysed these common answer questions, results mixed-methods-research project [1] were used, give view on impact use emerging technologies allow best suited technology. Based step previous [2], relevant tools IT architecture was defined. Thirdly, case study enrolled, which based previously defined architecture, using IoT measuring devices from European production, two different databases analytic tools. cover ESG-reporting demands, structure building structures The paper also presents final decision database analytics tool, both capable analyse large amount operated as open (enables enlargement at any time works without license cost).
