(This article belongs to the Special Issue Energy Efficiency in Smart Homes and Grids)
Here, we overview the Energies journal special issue that is dedicated to the topic of “Energy Efficiency in Smart Homes and Smart Grids” (https://www.mdpi.com/journal/energies/special_issues/Smart_Home_Grid (accessed on 5 April 2021)) and the papers published in it. The call for papers looking for new directions in the topic of “Energy Efficiency in Smart Homes and Smart Grids” was open in 2020, and the text announcing the special issue was as follows: “This Special Issue focuses on advancements in the energy efficiency of smart homes and smart grids. This encompasses smart homes, smart grids, smart cities and villages, ICT solutions for efficient energy consumption, as well as energy production and distribution. This Special Issue is especially interested in receiving high-quality, unpublished submissions that focus on advancing the technologies for sensor infrastructures, knowledge management, and engineering, as well as user engagement: in particular, energy savings should take place without a decrease in residents’ quality of life. We are interested in back-end technologies, such as for the predictive maintenance and optimization of energy distribution and consumption, as well as in front-end technologies, such as end-user interfaces, gamification, and techniques facilitating behavior change. Further, data are playing an increasingly important role in energy efficiency, and are gaining a leading role in various domains, such as future building certification, smart grid and meter management, and predictive maintenance. Specifically, we are looking into the combination of machine learning and semantic techniques, for example, combining them in order to create high-quality knowledge graphs in the energy efficiency domain for smart homes and smart grids”.
The applied keywords were as follows:

The special issue resulted in five published papers as follows. Managing and operating on data with AI techniques such as with machine learning and knowledge graphs remained the focus of the attention of the special issue. The papers have been focusing on looking into the specific details and techniques in smart grids [1], systems connecting smart grids and smart homes [2], as well as smart homes [3]. Furthermore, the physical characteristics of the systems and accounting of their features continue to play an important role in the addressed topic. In this issue, the impact of various characteristics of windows in buildings has been comprehensively overviewed by Cannavale et al. [4]. On the other hand, addressing the matters of energy-efficient buildings have been also shown from a very different, economic perspective [5].
