Social networks, social cohesion, and place attachment are positive social impacts that can stimulate people’s quality of life. High-rise apartment buildings are often criticized for their negative social impacts, such as social isolation and low levels of interaction and social cohesion. However, there is still insufficient empirical evidence on the relationships between neighborhood social networks, social cohesion, place attachment, and loneliness of high-rise apartment residents and how they are affected by the physical environment and neighborhood satisfaction. This study uses structural equation modeling (SEM) to investigate these relationships using data collected in four high-rise apartment complexes in Hanoi, Vietnam. While the number of neighbors in someone’s social network is found to stimulate social cohesion, which can foster neighborhood attachment and reduce feelings of loneliness, the possibility of improving these social impacts is affected by urban contexts, site properties, and the ability to provide communal spaces within and surrounding the buildings.

The ambition of a transition to a sustainable society brings forth the dual challenge to preserve historical buildings and simultaneously improve the energy performance of our built environment. While engineers claim that a dramatic reduction of energy use in the built environment is feasible, it has proven to be a difficult and twisting road.In this paper we focus on historical buildings, where difficulties of energy reduction are paramount, as such buildings provide local identity and a connection to our past. It is a EU policy objective to conserve and redesign heritage buildings like prisons, military barracks, factories, stations, and schools. Such redesign should also ensure reduction of energy use without compromising historical identity. In this paper we conceptually and empirically investigate how the two conflicting aspirations unfold. In particular we elaborate the obduracy and scripts of buildings, to clarify how they resist change and invite a specific use. We analyse the tensions between identity and energy conservation in a case study of a restoration project in Franeker. This buildinghas recently undergone a restoration, with energy efficiency as one of its goals.Scripts and networks are traced by a combination of methods, such as studyinglayout, materials and building history, and qualitative interviews with restoration architects and users. We identified three types of strategies to conserve identity and energy: design strategies; identity strategies and network strategies. Such strategies are also relevant for other efforts where conservation and innovation have to be reconciled.
Dealing with and maintaining high-quality standards in the design and construction phases is challenging, especially for on-site construction. Issues like improper implementation of building components and poor communication can widen the gap between design specifications and actual conditions. To prevent this, particularly for energy-efficient buildings, it is vital to develop resilient, sustainable strategies. These should optimize resource use, minimize environmental impact, and enhance livability, contributing to carbon neutrality by 2050 and climate change mitigation. Traditional post-occupancy evaluations, which identify defects after construction, are impractical for addressing energy performance gaps. A new, real-time inspection approach is necessary throughout the construction process. This paper suggests an innovative guideline for prefabricated buildings, emphasizing digital ‘self-instruction’ and ‘self-inspection’. These procedures ensure activities impacting quality adhere to specific instructions, drawings, and 3D models, incorporating the relevant acceptance criteria to verify completion. This methodology, promoting alignment with planned energy-efficient features, is supported by BIM-based software and Augmented Reality (AR) tools, embodying Industry 4.0 principles. BIM (Building Information Modeling) and AR bridge the gap between virtual design and actual construction, improving stakeholder communication and enabling real-time monitoring and adjustments. This integration fosters accuracy and efficiency, which are key for energy-efficient and nearly zero-energy buildings, marking a shift towards a more precise, collaborative, and environmentally sensible construction industry.
