DataSites: A Simple Solution for Providing Building Data to Client Applications

Nowadays, energy consumption and especially energy saving are important issues. The concern over global warming has increased the need to save energy in many areas of our living community. One way of slowing global warming is to reduce energy consumption and the related emissions. IoT systems can be utilized to monitor living conditions in residential and commercial buildings. These IoT systems continuously produce huge amounts of data. Similarly, various vendor-specific building automation systems generate data on an equal scale. Combining these data sources can be challenging, as protocols and data are seldom in a unified and interoperable format. In this paper, we present the DataSites service, which integrates back-end systems and client-oriented REST APIs. The high-level view of DataSites architecture, how to relay building data to client applications, and the required interfaces are described in this paper. Use of the service is illustrated using two real-life use cases.
