Surface space constraints and the associated massive carbon emissions present significant challenges to the sustainable development of megacities. Urban underground space (UUS) construction is expected to provide a practical approach for alleviating the space constraints of surface construction. However, in-depth examinations of the overall UUS sys...

The great challenge of global climate change urges world economies to reduce greenhouse gas emissions and promote sustainable development, where the building sector plays a vital role. Carbon tracking technology is one of the keys to capturing carbon emissions for sustainable construction such as net-zero buildings. This paper reviews five key carb...

High-rise high-density cities around the world suffer from severe urban heat island effects. Greenery has the potential to heal urban microclimates, such as shading, lowered air temperatures, and increased humidity, apart from other benefits to urban health. Existing numerical simulation studies employing simplified, proxy greenery models have vali...

The existing Environmental, Social, and Governance (ESG) frameworks lack transparency and consistency in reporting and can introduce extra costs to the industry. This study proposes a blockchain-based token economic model to incentive construction companies for their ESG performance and addresses the issues of transparency. The model is expected to...

The AEC industry is undergoing a digital transformation, which is leading to partially blended learning modes in collaborative and interactive learning environments. However, online meeting software has been found to have limited capacity when it comes to teaching and learning complex geometries and systems in AEC courses. To address this issue, th...

Building sector plays a significant role in China's ambitous climate targets to peak carbon emissions (CEs) by 2030 and to realize carbon neutral by 2060. However, studies in characterizing the CEs of urban residential buildings from life-cycle perspective at regional level are still limited, especially for the Guangdong-Hong Kong-Macao Greater Bay...

The emergence of fifth-generation (5G) telecommunication would change modern lives, however, 5G network requires a large number of base stations, which may lead to greater carbon emissions. Since 2020, over 700,000 5G base stations are in operation in China. This study aims to understand the carbon emissions of 5G network by using LCA method to div...

China has been striving to urbanize in recent years. Accordingly, decoration waste is triggering an enormous challenge to green development if effective management hardly adopted. Authentic statistics or accurate estimation of decoration waste generation can play crucial roles in handle this problem. This study takes Guangzhou city as an example, i...

China is committed to peaking its carbon emissions by 2030 and become a carbon-neutral society by 2060. The building sector that accounts for over one-third of the total carbon emissions is expected to face a great challenge in helping China achieve this goal. Shenzhen, as a low-carbon pilot city, whether its low-carbon work of urban buildings reac...

Continuing urbanization and significant improvement of lifestyle have ushered in high demand for building floor area, inevitably leading to a rapid increase of interior decoration and renovation activities, which in turn produce a massive quantity of decoration and renovation waste (DRW). However, like many other countries with unremitting demand f...
