The building sector stands for about one-third of the emissions from energy systems. Several studies are examining this, and yet the energy demand in buildings keeps increasing every year. To develop a relatively leisurely industry more implementations of IT solutions are advantageous. By streamlining buildings through data-driven approaches energy savings are possible and smart buildings are generated. This study aims to examine the current circumstances of energy management in the building industry, and through this understanding a search for existing barriers connected to gathering and analyzing energy data and its associated digital solutions. This will consequently lead to a comprehension of what future potential there is of building energy management. In order to get an understanding of this a literature review on the subject was done, as well as two interviews with relevant actors. The result of the interviews was integrated with the associated analysis. This was discussed together with the result from the literature review which showed that more implementations of submeters in buildings are demanded to be able to do required analysis. The monitoring of buildings is improved if the system connected to BEMS is intelligent, by applying IoT sensors. Interoperability is relevant to keeping track of considering old and new technology are inevitably going to be combined. There is a knowledge gap in relation to smart implementations in buildings, which should be prioritized to reduce in order to optimize the outcome of smart buildings.
