Editor: Domingos, Leonor Marques Mano; Sousa, Maria José Resumo: Building information modelling (BIM) optimises life cycle assessment (LCA) processes by automating the detailed extraction of quantities from BIM models and reducing labour-intensive processes. However, it is difficult to identify the most effective and accurate BIM-based LCA approach, which depends on the design phase, the maturity of the BIM information, modelling techniques and the overall goal of the LCA. Additionally, there is a shortage of systematic knowledge regarding the present obstacles and potential directions for BIM-based LCA. This article conducts a systematic literature review analysing 65 publications between 2013 and 2024, using scientometry techniques and detailed content analysis. The results show that current methods still require many manual processes that can be automated, namely the BoQ edition and mapping of LCA data; do not allow for continuous monitoring of environmental impacts throughout the design stages; and are not adapted to renovation or refurbishment BIM models. Furthermore, although LCA and the circular economy are directly related concepts, there is a lack of research into how circular economy strategies quantitatively influence LCA results and methods.

J. Editor: Kornyshova, Elena; Deneckère, Rébecca; Brinkkemper, Sjaak Resumo: Smart tourism (ST) stems from the concepts of e-tourism - focused on the digitalization of processes within the tourism industry, and digital tourism – also considering the digitalization within the tourist experience. The earlier ST references found regard ST Destinations and emerge from the development of Smart Cities. Our initial literature review on the ST concept and Smart Tourism Tools (STT) revealed significant research uncertainties: ST is poorly defined and frequently linked to the concept of Smart Cities; different authors have different, sometimes contradictory, views on the goals of ST; STT claims are often only based on technological aspects, and their “smartness” is difficult to evaluate; often the term “Smart” describes developments fueled by cutting-edge technologies, which lose that status after a few years. This chapter is scoped in the ongoing initiative of building an online observatory to provide a broad view of STTs' offerings in Europe. Such an observatory requires methodologies and tools to evaluate “smartness” based on a sound definition of ST and STT and being able to cope with technological evolution. We describe herein the results of a participatory approach where we invited ST experts worldwide in our effort to reach that soundness.

N.; Brito e Abreu, F. Editor: Kornyshova, Elena; Deneckère, Rébecca; Brinkkemper, Sjaak Resumo: Overtourism occurs when the number of tourists exceeds the carrying capacity of a destination, leading to negative impacts on the environment, culture, and quality of life for residents. By monitoring overtourism, destination managers can identify areas of concern and implement measures to mitigate the negative impacts of tourism while promoting smarter tourism practices. This can help ensure that tourism benefits both visitors and residents while preserving the natural and cultural resources that make these destinations so appealing. This chapter describes a low-cost approach to monitoring overtourism based on mobile devices’ wireless activity. A flexible architecture was designed for a smart tourism toolkit to be used by small and medium-sized enterprises (SMEs) in crowding management solutions, to build better tourism services, improve efficiency and sustainability, and reduce the overwhelming feeling of pressure in critical hotspots. The crowding sensors count the number of surrounding mobile devices, by detecting trace elements of wireless technologies, overcoming MAC address randomization. They run detection programs for several technologies, and fingerprinting analysis results are only stored locally in an anonymized database, without infringing privacy rights. After that edge computing, sensors communicate the crowding information to a cloud server, by using a variety of uplink techniques to mitigate local connectivity limitations, something that has been often disregarded in alternative approaches. Field validation of sensors has been performed on Iscte’s campus before their planned use in other locations, such as the Pena Palace in Sintra. Preliminary results show that these sensors can be deployed in multiple scenarios and provide a diversity of spatiotemporal crowding data and analysis in order to promote smart engineering techniques to be used for tourism overcrowding management.

S.; Trocado, P.; Prata, A.; Brito e Abreu, F. Editor: Kornyshova, Elena; Deneckère, Rébecca; Brinkkemper, Sjaak Resumo: Immersive technologies, such as augmented reality (AR) and virtual reality (VR), are effective technologies being implemented across diverse fields. We propose an AR/VR-based web app to be applied in the cultural tourism field with the objective of enhancing the visitors’ experience of the Monserrate Palace, part of a UNESCO cultural landscape located in Sintra, Portugal, managed by Parques de Sintra ś Monte da Lua SA. This chapter overviews the state of the art on immersive technologies in cultural heritage sites and the visitor experience at these sites. Then, it exposes the palace’s historical and cultural significance and some of the challenges it faces in engaging its visitors. The potential applications of immersive technologies in the palace are explored, including interactive storytelling and immersive experiences that allow for a higher level of visitor engagement. Next, it addresses potential challenges and limitations of deploying the proposed solution in the palace, such as technical constraints and preservation concerns. It then concludes with a reŕection on the significant potential of AR and VR in enriching the immersive experience of Monserrate Palace, offering new possibilities for engaging with cultural heritages and creating a memorable and enjoyable visit for modern audiences.
