Purpose: This research aims to study the relationship between trust and knowledge sharing intention. Furthermore, the overarching objective of this study also determines the moderating effect of Perceived Behavioral Control on this relationship.Design/methodology/approach: Structural Equation Modelling (SEM) was applied using Smart PLS 3.3 to analyze the data.Findings: The results of this study reveal that Perceived Trustworthiness and Propensity to Trust positively affect Explicit and Tacit knowledge sharing intention. Perceived behavioral control was also found to positively moderate the relationship between perceived trustworthiness and tacit knowledge sharing intention.Originality/value: This study has provided evidence that trust among the construction project team members leads to an increase in the knowledge sharing intention among project team members.

The high energy consumption in the building sector and the increasing impacts of climate change have necessitated the transition to net-zero-energy buildings (NZEBs), in which energy retrofit strategies play a key role. However, neglecting moisture transport and climatic design while improving energy efficiency often leads to reduced building performance, material deterioration, worse occupant health, and indoor environmental problems. This review examines in detail the basic mechanisms of moisture transport, including diffusion, capillary action, and airborne moisture transport, and illustrates how poor moisture control affects thermal performance and resident health. Additionally, a comparative analysis of the impact of retrofit strategies implemented in different climatic regions on energy efficiency, carbon emission reduction, moisture-related failures and net-zero goals is conducted. At the same time, the need exists to incorporate awareness regarding the adverse effects on the health of occupants. This systematic review analyzed 120 peer-reviewed studies published from 1994 to 2026, covering different climatic regions (e.g., cold, temperate, warm–humid, etc.). The analysis found that the energy savings rates were reported to range from 18% to 45%, while the moisture-related failures in inappropriately retrofitted buildings were observed to increase by up to 32% in some cold regions. This research review provides a comprehensive advisory framework for domestic residents to take remedial steps until retrofit experts gain access in order to prevent health risks from mold and moisture ingress, which can contribute to a healthy lifestyle and a net-zero-energy building.

The urban housing sector plays a significant role in global energy consumption and carbon emissions, making the sustainable transformation of domestic buildings essential to achieving climate goals. Urban housing is also linked to the energy transition, social equity, public health, and environmental resilience. The UK’s Warm Homes Plan (WHP) is seen as a key policy initiative that aims to improve energy efficiency and living conditions, and to promote the transition to a low-carbon future. This study provides an integrated review of retrofit assessment, policy mechanisms, and socio-environmental factors in the context of urban housing decarbonization. This study adopts a structured critical review approach to analyze retrofit strategies, low-carbon heating systems, renewable energy integration, and smart control technologies. The study highlights that retrofit assessment is not limited to technical performance but also includes social acceptability, affordability, and urban infrastructure compatibility. Furthermore, case study comparisons show that decarbonization outcomes are improved when technical measures are integrated with effective governance, stakeholder engagement, and local policy support. This study presents an integrated conceptual framework that links technical retrofit measures, policy coordination, and socio-environmental indicators. The results show that isolated technical solutions are insufficient for decarbonizing urban housing. Rather, a multi-dimensional planning approach is necessary to enable a sustainable, resilient, and socially inclusive housing transition.

This study aims to examine the role of Relational Stakeholder Management (RSM) on the success of sustainable construction projects in urban areas of Pakistan. The study also examines the mediating role of trust (competence trust, integrity trust, and intuitive trust) and the moderating role of project managers’ leadership skills. Data were collected from 303 professionals working on sustainable construction projects in Pakistan and analyzed using Structural Equation Modeling (SEM). The results show that RSM has a positive and significant direct impact on the success of sustainable construction projects, while competence trust and integrity trust mediate this relationship. However, Intuitive Trust did not mediate the relationship between RSM and project success. Furthermore, the project manager’s leadership competencies strengthen relationships with relational stakeholders and foster trust, thereby improving overall project success. This research highlights that, in addition to technical factors, human and relational aspects are crucial to the success of energy-efficient and low-carbon construction projects in urban areas of Pakistan. The study provides integrated empirical evidence on the interplay between stakeholder relationships, trust, and leadership, specifically in the context of sustainable construction projects in urban areas of Pakistan. The findings of the study provide practical insights to improve RSM, develop trust, and strengthen leadership competencies to enhance success in sustainable construction projects.
