Special Issue Information

Dear Colleagues,

Digital technology and smart buildings are key elements for achieving a carbon-neutral and sustainable green society by 2050. In particular, due to the development of digital technologies such as the Internet of Things, big data, and artificial intelligence, buildings are rapidly changing into smart spaces. In addition, cloud-based platform technology has made buildings into a single digital product and provides a better life through the connection between buildings and cities. Furthermore, digital twin and energy data analysis technology have made it possible to use buildings as an object in establishing national strategies for carbon neutrality. In other words, various digital technologies are suggesting directions for the scalability and development potential of future smart buildings for carbon neutrality.

At this point, the direction of future building is clear. However, although various intelligent technologies are being applied to buildings, the practical verification of advanced technologies and smart services is still required in the fields of building management, lighting, energy, facilities, fire safety and security. Therefore, the purpose of this Special Issue is to exchange various ideas related to digital innovation technology applicable to buildings from an environmental, social and technological viewpoint. We invite you to submit interdisciplinary experiments and theoretical research on digital technologies and smart buildings. Research may include, but is not limited to, theoretical and empirical research on the following subjects:

  • Digital transformation for smart buildings;
  • Sustainable service in buildings;
  • The role of buildings for carbon neutrality;
  • Digital technology for smart buildings;
  • Cloud-based smart building platforms;
  • Digital-twin applications for smart building service;
  • Advanced building energy management systems;
  • AI-based automation control systems and algorithms for buildings;
  • Data analysis and prediction for smart buildings.

This study aims to enable cost-effective Internet of Things (IoT) system design by removing redundant IoT sensors through the correlation analysis of sensing data collected in a smart home environment. This study also presents a data analysis and prediction technology that enables meaningful inference through correlation analysis of data from different heterogeneous IoT sensors installed inside a smart home for energy efficiency. An intelligent service model that can be implemented based on a machine learning algorithm in a smart home environment is proposed. Herein, seven types of sensor data are collected and classified into sets of input data (six environmental data) and target data (power data of HVAC). By using the six new input data, the power data can be predicted by the artificial intelligence model. The model performance was measured using RMSE, and the gradient-boosting regressor (gb) model performed the best, with an RMSE of 22.29. Also, the importance of sensor data is extracted through correlation analysis, and sensors with low importance are removed according to the importance of sensor values. This process can reduce costs by 13%, thereby providing a design guide for a cost-effective IoT system. Full article

To realize carbon neutrality, understanding the energy consumed in the building sector, which is more than that in other sectors, such as industry, agriculture, and commerce, is pivotal. Approximately 37% of energy consumption belongs to the building sector, and management of building energy is a critical factor. In this paper, we present an energy sharing scenario for energy stabilization, assuming that electric vehicles and their charging stations are widely distributed in the future. Consequently, fewer fuel cars will exist, and electric cars will become the major mode of transportation. Therefore, it is essential to install charging stations for electric vehicles in the parking lots of future buildings, and business models are expected to expand. In this paper, we introduce a future energy stabilization mechanism for peak power management in buildings and present a platform that entails connection-based energy trading technology based on a scenario. We also propose an energy supply strategy to prevent excess prices incurred due to peak consumption. Then, we analyzed the electricity bill for one month through scenario-based simulations of an existing building and the proposed system. When applying the proposed system, we derived a result that can reduce electricity rates by 38.3% (best case) to 78.5% (worst case) compared with the existing rates. Full article

Digital Twin Technology (DTT) has gained significant attention as a vital technology for the efficient management of smart cities. However, its successful implementation in developing countries is often hindered by several barriers. Despite limited research available on smart city development in Malaysia, there is a need to investigate the possible challenges that could affect the effective implementation of DTT in the country. This study employs a mixed methodology research design, comprising an interview, a pilot survey, and the main survey. Firstly, we identified barriers reported in the literature and excluded insignificant factors through interviews. Next, we conducted an Exploratory Factor Analysis (EFA) on the pilot survey results to further refine the factors. Finally, we performed a Structural Equation Modeling (SEM) analysis on the main survey data to develop a model that identifies barriers to DTT implementation in smart city development in Malaysia. Our findings suggest the presence of 13 highly significant barriers, which are divided into four formative constructs. We found that personalization barriers are highly crucial, while operational barriers were less important for DTT implementation in smart city development in Malaysia. Full article
