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.

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.

High-Performance Tall Buildings: An Overview of Recent Developments
The evolution of tall buildings has been shaped by distinct architectural styles, beginning around 1875 and progressing through various stylistic architectural movements. These changes were driven by advancements in structural engineering and digital design technologies, leading to greater experimentation with form and function. Energy and resource conservation of the late 20th century instigated a noteworthy focus on sustainability. Beyond that, the early 21st century saw a significant shift toward a new breed of tall buildings, a suitable architectural vocabulary for “high-performance” tall buildings, in which sustainability with a focus on energy efficiency is joined with the performance of other active and passive functional systems. This paper presents an overview of high-performance tall buildings by exploring key technologies, materials, innovations, safety, durability, and indoor environmental quality. Strategies that have emerged to address skyscrapers’ environmental and economic challenges are also crucial in such a building. It highlights the importance of optimizing and integrating building systems, improving energy efficiency, minimizing resource consumption, and ensuring long-term occupant health and productivity. Furthermore, this study identifies five key dimensions—structural materials and systems, energy-efficient design, high-performance façades, performance monitoring, and integrating building services systems—demonstrating how these factors contribute to environment-conscious urban development and resilient architectural and engineering design. It is concluded that these buildings are poised to redefine urban environments by leveraging advanced technologies, AI-driven management, IoT interconnectivity, health-focused elements, and climate resilience. Also, tall, high-performance buildings will be increasingly automated to an unknown limit, and AI will play a prominent role in the future.
