Pathway to Sustainability in Buildings
Traditional energy sources, such as coal, oil, and natural gas, are finite and face depletion. With the global concern over climate change and the limited nature of traditional energy resources, there is a critical need to transition towards more sustainable and eco-friendly energy solutions, especially within the built environment.

Biopolymers Used in Cladding
Cladding is used as the outer layer in high-rise buildings to protect the building from weather conditions and enhance its visual appeal. Its primary function is to shield structures from environmental factors such as radiant sunlight and moisture, thereby preserving their structural integrity.

Effect of Aggregate on Geopolymer Concrete
The construction industry has become one of the major consumers of renewable and non-renewable natural resources and environment-polluting industries. The development of new green construction materials has become a global need and a driver for recent research trends. The use of geopolymer binders can reduce the consumption of ordinary cement and utilize several wastes that are usually dumped in landfills, causing several environmental issues.

Cementitious and Geopolymer Composites with Lithium Slag Incorporation
Lithium slag (LS)’s particle size distribution is comparable to fly ash (FA) and ground granulated blast furnace slag (GGBS), which suggests it can enhance densification and nucleation in concrete. The mechanical treatment of LS promotes early hydration by increasing the solubility of aluminum, lithium, and silicon. LS’s compositional similarity to FA endows it with low-calcium, high-reactivity properties that are suitable for cementitious and geopolymeric applications. Increasing the LS content reduces setting times and flowability while initially enhancing mechanical properties, albeit with diminishing returns beyond a 30% threshold. LS significantly improves chloride ion resistance and impacts drying shrinkage variably.

Digitalization of Construction Projects through Integration
The construction industry has fared poorly in the process of digital transformation, while the main challenge is the digitalization of construction projects. Changes in project management approaches are urgently required in construction organizations to better align digital technology and organizational conditions.

The Role of Moisture in Alkali–Silica Reaction
Moisture is an important factor for ASR and its availability in concrete has often been appraised with the aid of relative humidity (RH). Its sufficiency leads to improved kinetics and higher ultimate ASR-induced expansion. Numerous RH thresholds have been reported to be required to initiate and sustain the reaction. the tests from which the thresholds has been reported differ in terms of the temperature, sample size, reactivity level of aggregates and aggregate type (Fine versus Coarse). All of these factors can be hypothesized to influence the role of moisture in the reaction.

AI-Based Evaluation of Streets for People in Bangkok
Bangkok, the capital of Thailand, grapples with several urban challenges, including traffic accidents, congestion, and underdeveloped sidewalks. These issues stem from the escalating use of private cars and motorcycles driven by rapid urbanization, accompanying economic growth, and the unique street geometry of the city. Furthermore, despite the development of railroads, issues persist with the poor walking environment for pedestrian access to stations, posing a challenge to the promotion of safe and environmentally friendly public transportation. This study evaluated streets’ spatial performance, focusing on the performance of soi, the intricate network of narrow urban pathways in Bangkok. Leveraging an AI model capturing pedestrian value, this study subsequently assessed accessibility from typical residential areas to public transportation stations. The findings shed light on the challenges faced by sois in Bangkok. Based on the findings, practical implications were discussed and provided to inform urban designers, with the aim of promoting public transportation usage and encouraging a more sustainable urban form.
