A Digital Twin for Energy Consumption Prediction and Thermal Comfort Monitoring in Residential Buildings

The residential buildings are responsible for approximately one-quarter of the world’s energy consumption and they play an important role in mitigating global climate change [1]. To improve energy efficiency and reduce carbon emissions in the residential building sector, it is necessary to predict the energy consumption and thermal comfort under urban climate change. Nowadays, a large number of IoT sensors, smart devices, and controllers are employed in residential buildings to collect data in a real time and seamless way [2]. Emerging digital technologies such as digital twins and artificial intelligence (AI) have proven to be a powerful tool to provide dynamic, reliable, robust, and agile models for predicting and monitoring the energy consumption and air pollutant emission levels in industrial sectors. However, digital twins have received very little attention in the residential building sector [3]. The main aim of this study is to design and prototype a digital twin system for thermal comfort monitoring, visualization, tracking, energy management, prediction, and optimization in residential buildings under different indoor and outdoor conditions. Our digital twin model is built on the basis of a thermodynamic model incorporating building attributes such as heating methods, wall materials, etc. with real-time sensor and IoT information updates to deliver precise predictive foresight and also determine the different indoor and outdoor factors contributing the most to residential heating energy consumption and thermal comfort. The digital twin model will be tested on a dataset containing sensor data, building attribute features, and weather records during five heating seasons of residential buildings in a city in Russia that was published for the first time in 2020 by IEEE DataPort [4].
