Digital Twin Approach in Buildings

In 2011, the term Digital Twin was originally introduced by Michael Grieves to define the synchronization between two realities: physical objects placed in a real space and virtual objects within in virtual space, linked through the mutual exchange of data throughout the entire lifecycle, both in real-time and asynchronously. Digital Twin is among the principal and emerging technological innovations of both Industry 4.0 and the emerging Industry 5.0, enabling an interaction between physical and virtual objects, Big Data, Internet of Things, and Artificial Intelligence. The construction sector, too, is now exploring the potentialities offered by the Digital Twin approach in enhancing innovative, responsible, and sustainable governance of buildings’ lifecycles.

Time-Domain Numerical Simulations for Horizontal-Axis Offshore Wind Turbines

In addition to a carbon-neutral vision being recognized worldwide, the utilization of wind energies via horizontal-axis wind turbines, especially in offshore areas, has been intensively investigated from an academic perspective. Numerical simulations play a significant role in the design and optimization of offshore wind turbines.

Edge Computing for Traffic Characterization

Traffic flow analysis is essential to develop smart urban mobility solutions. Although numerous tools have been proposed, they employ only a small number of parameters. To overcome this limitation, an edge computing solution is proposed based on nine traffic parameters, namely, vehicle count, direction, speed, and type, flow, peak hour factor, density, time headway, and distance headway.

Biochar and Bacillus subtilis Enhance Concrete Performance

This study evaluated the influence of adding biochar and the bacterium Bacillus subtilis on the physical and mechanical properties of concrete designed for a compressive strength of f’c = 280 kg/cm² in Chiclayo, aiming to improve its performance and promote sustainable construction practices in line with SDG 9. Concrete mixes were prepared with four combinations of biochar and Bacillus subtilis (C1, C2, C3, C4). The evaluated properties included physical characteristics as well as compressive, flexural, and tensile strength. Results showed that the mix containing 2% biochar and 4.50% Bacillus subtilis exhibited the best performance, with increases of 4.54% in compressive strength, 6.72% in tensile strength, and 51.70% in flexural strength, attributed to the combined effect of biochar as a microfiller and the bacterium as a biocementing agent. Furthermore, in the modeling of an eight-story building, the experimental concrete demonstrated better structural performance compared to the control, meeting the drift limits established in E.030. These findings indicate that the combined addition of both materials improves density, strength, and linear seismic performance of concrete, positioning it as an innovative and sustainable alternative for the development of more resilient infrastructure.

Enhancing Cost Prediction and Estimation Techniques for Sustainable Building Maintenance and Future Development

Building maintenance is crucial, yet predicting financial resources for it remains challenging, particularly during the design and construction phases. This research aims to analyze and synthesize existing studies on maintenance cost estimation, with a focus on identifying key trends, methodologies, and sustainability considerations. The review finds that most studies emphasize educational and office buildings, while limited attention has been given to infrastructure such as bridges and roads. Moreover, growing attention is being directed toward early-stage maintenance cost estimation and integrating sustainability principles into cost prediction models. The findings underscore that incorporating sustainability factors in maintenance planning enhances long-term performance, reduces lifecycle costs, and supports future-ready building management. The study concludes by highlighting the need for more comprehensive, sustainability-oriented frameworks to improve the accuracy and applicability of maintenance cost estimation in the built environment.
