Resilient Scheduling and Construction Projects
Resilient schedules are defined by their multidimensionality: they tend to be robust, flexible, and adaptable. Previous studies in construction scheduling have predominantly focused on the robustness aspect, which is already a complex concept. On the one hand, robustness depicts the insensitivity of objective function in the optimization model, may it be project minimization or NPV maximization, for example; on the other hand, it tends to minimize the deviations between baseline schedule and realized state.

Thermal Comfort Indices Through Room Occupancy Prediction
Room occupancy prediction based on indoor environmental quality may be the breakthrough to ensure energy efficiency and establish an interior ambience tailored to each user. Identifying whether temperature, humidity, lighting, and CO2 levels may be used as efficient predictors of room occupancy accuracy is needed to help designers better utilize the readings and data collected in order to improve interior design, in an effort to better suit users. It also aims to help in energy efficiency and saving in an ever-increasing energy crisis and dangerous levels of climate change.

Optimization of Dynamic Shading Structures
This work implements parametric tools to optimize the environmental design of urban adaptive shadings through multiobjective evolutionary algorithms that look for solutions of dynamic (time-changing) structures used in open public spaces. The proposal is located in Malecon Cancun Tajamar in the southeast part of Mexico, and the main objective is to enhance the thermal comfort of users as well as to become part of the social dynamics of the place reinforcing identity through appropriation. The proposed workflow includes four steps: (1) geometric modelling by parametric modelling tools; (2) simulation of environmental parameters by using BPS tools; (3) shape optimization by using an evolutionary algorithm; and (4) environmental verification of the results. The Universal Thermal Climate Index (UTCI) was used to assess the outdoor thermal comfort derived from the dynamic shadings. The results showed a significant improvement in the thermal comfort with absolute UTCI differences of 3.9, 7.4, and 3.1 °C at 8, 12, and 16 h, respectively, during the summer; and absolute differences of 1.4, 3.5, and 2 °C at 8, 12, and 16 h, respectively, during the winter. The proposed workflow can help to guide the early design process of dynamic shadings by finding optimal solutions that enhance outdoor thermal comfort.

Deep Learning Algorithms for Structural Health Monitoring
Environmental effects may lead to cracking, stiffness loss, brace damage, and other damages in bridges, frame structures, buildings, etc. Structural Health Monitoring (SHM) technology could prevent catastrophic events by detecting damage early. In recent years, Deep Learning (DL) has developed rapidly and has been applied to SHM to detect, localize, and evaluate diverse damages through efficient feature extraction.

Defensible Spaces
Defensible space is the concept of creating spaces that include a series of architectural guidelines that are used when designing a new urban residential area to promote both the territorial claim of the residential groups to their surroundings and their ability to conduct natural surveillance of their spaces. Constructing safe environments with safe vocabularies for enhancing well-being is crucial for achieving quality of life in both peace and wartime. Warzone countries that suffer from many changes due to the effect of war (or fourth-generation wars) should be prepared to face those changes with safe spaces as well.

Temporary Housing Design of Post-Disaster Scenarios
Disasters, whether natural or man-made, pose inevitable global challenges. Events such as COVID-19, earthquakes, extreme climatic conditions, and conflicts underscore the urgent demand for effective temporary housing solutions. These temporary housing units (THUs) serve as an aid in assisting displaced people to rebuild their lives as the recovery process unfolds. However, numerous temporary housing units present environmental, economic, and social issues that hinder their sustainability.

Critical Success Factors for Building Information Modeling Implementation
The building sector is widely acknowledged as a driving force behind national prosperity. However, there are considerable challenges to the construction industry’s transition to sustainable practices, including regarding building information modeling (BIM) technologies. The United Arab Emirates has made significant progress in the Middle East in adopting building information modelling (BIM) technologies. Green building approaches have been advanced through their incorporation into environmentally conscious building practices, with a large body of literature responding to this issue. Several projects in the United Arab Emirates have, however, made use of the complementary nature of BIM and UAE sustainable policies. However, not everybody has employed the full potential of BIM implementation in sustainable construction.

Construction Waste Recycling
Construction waste is an issue that has attracted increasing worldwide attention recently. With the rapid development of socioeconomic and urbanization in China, the building industry has emerged as a pillar of the national economy. In particular, a large number of raw materials are used and massive construction waste is generated along a gradient of increasing urbanization, resulting in environmental pollution and scarcity of nature resource. At present, construction waste recycling has been proven to be the most effective method of managing construction trash.

Building Integrated Photovoltaic
BIPVs offers tremendous potential to building designers or Architects, provided that their introduction is well considered and catered for from the very beginning of the design stages and not left afterwards. They can influence building orientation footprints, layout and form; this is apart from changing the building as well as being an important element of the environmental setting and building systems. It is important here to stress their recognition as an essential part of the energy strategy of the building and it’s functioning, since careful and proper integration of PVs with other building elements is a key factor to their success. Moreover, their high aesthetical values in terms of neat, coloured and high-tech prestigious appearance can be a corner stone for more innovative architectural designs. To ensure proper integration of PVs into the building fabric we need to point certain factors that influences Pv performance as they are integrated in a building design. As well as assessing the nature and type of loads involved. Influence of PVs on building factor is also important, since PVs are considered expensive nowadays it is fairly important to use them as optimal as possible; this remind us with the use of glazing in the middle ages, which was expensive and rare, nowadays we see them almost every where.

The Causal Factors of Elevator Maintenance
Maintenance is crucial for healthcare facilities in terms of both the continuity of operations and annual costs. Many maintenance issues are associated with design decisions that pave the way for added costs in later lifecycle stages. Some systems, e.g., elevators, are sources of maintenance costs; additionally, elevator outages are significant issues for multi-floor healthcare facilities. Considering the maintainability of elevators from the early design stages helps to highlight potential maintenance issues in later stages. This also assists in mitigating costs by avoiding design decisions that result in future maintenance costs.

Multi-Class Defect Detection
Defects in residential building façades affect the structural integrity of buildings and degrade external appearances. Defects in a building façade are typically managed using manpower during maintenance. This approach is time-consuming, yields subjective results, and can lead to accidents or casualties. To address this, we propose a building façade monitoring system that utilizes an object detection method based on deep learning to efficiently manage defects by minimizing the involvement of manpower. The dataset used for training a deep-learning-based network contains actual residential building façade images. Various building designs in these raw images make it difficult to detect defects because of their various types and complex backgrounds.
