p> As deep learning AI becomes more and more common in business and even in our daily lives, it is important to understand what the carbon impact of this type of software is. Recent papers have shown that it can be quite great, i.e., the training of a single high-end model can result in emissions of more than 500t of CO2eq. In this article we descr...

A transition from fossil to renewable energy requires the development of sustainable electric energy storage systems capable to accommodate an increasing amount of energy, at larger power and for a longer time. Flow batteries are seen as one promising technology to face this challenge. As different innovations in this field of technology are still...
The Belt and Road Initiative (BRI) makes headway in constructing railway projects invested by China, yet related environmental impacts are rarely discussed. Here we quantify the carbon footprint of railway project construction (RPC) under the BRI and identify the drivers behind their variations to find possible carbon reduction pathways. Our result...
Renewable energy sources serve as an alternative to conventional energy sources, with the main advantages being their inexhaustible nature and the absence of or significant reduction in greenhouse gas emissions. On the other hand, the development of energy production utilising renewable sources remains controversial, primarily because of the high i...

... First and foremost, geographic information systems (GIS) have been exploited for architectural and structural analysis, decay identification and selection of intervention priorities, particularly in the fields of structural assessment and risk vulnerability analyses against natural risks, such as earthquakes and fire [12,13]. In these applications, GIS might be integrated with computer-based models, within historical building information modelling (HBIM) environments, in view of their remarkable suitability to act as storing and managing platforms at the building and district scale [14][15][16][17]. Conversely, the combination of GIS with reality-based models, from terrestrial laser scanning (TLS) and/or close range digital (CRP) photogrammetry is less investigated at the territorial scale, although numberless works can be found on the employment of these techniques for decay mapping and diagnosis [18,19], due to the capability of coloured point clouds, texturized polygonal meshes and orthoimages to support detailed observations on surface colours, textures and geometries, even by supervised and automatic routines [20,21]. ...
Within the energy assessment and retrofitting of historical buildings, a key role is played by understanding and counteracting moisture-related problems, which might result from a variety of sources, including vapour condensation, soil water content, rain infiltration and/or hygroscopic materials. As a matter of fact, these problems seriously affect both the occupants’ well-being and the structures’ performance and durability, and thus call for effective and efficient management. In the case of historical city centres, the recurring similarities of construction techniques, environmental surroundings, maintenance conditions and protective regulations require coordinated methods and tools of analysis and treatment that might optimize data collection, investigation procedures and action planning. In this regard, an outstanding paradigm shift is enabled by digital technologies for survey, elaboration and decision-making. Within this framework, the paper discusses a workflow for decay assessment and treatment of moisture-related problems, based on geographic information systems (GIS) and close-range photogrammetry (CRP) techniques, with application to the facades of the historical area of Sassi di Matera, South Italy, in order to support the identification of anomalies and causes. The results are meant to validate an affordable and reliable pathway for city administrators and professionals in managing energy efficiency and sustainability of historical urban centres.
... For evaluating the relevance of the proposed PCM panel at the neighbourhood level combined with passive air flow in buildings and the implementation of NBSs, a digital model of a neighbourhood must be obtained. The proposed methodology is presented on Figure 6 according with the procedure developed by Orozco et al. [23,24]. The research was implemented in a peripheral neighbourhood of Valencia, Spain, called Benicalap, which has a hot semi-arid climate according to Köppen Climate Classification [25]. ...
... When a building is refurbished, PureTemp23 PCM panels will be installed and internal air flow ducts installed from the warm to the cold face, reducing the comfort temperature requirements by 2 °C. Figure 6. Procedure followed for developing the neighbourhood digital model [24]. ...

Climate change is driving urban development policies for nearly all cities, which are responsible for over 40% carbon emissions in the world. UN SDG 11 (“Make cities and human settlements inclusive, safe, resilient and sustainable”) defines critical indicators focused on carbon footprint reduction through green policies and city heritage preservation. Urban regeneration should ensure climate comfort for citizens while enhancing legacy urban resilience. New solutions for urban regeneration such as Phase Change Materials (PCMs) provide inexpensive energy adaption solutions by reducing peak thermal loads, and their market share is growing yearly by 16% (OECD market trends). However, these materials must be integrated into recyclable flexible building elements to ensure tailored responses to different seasons and climates. Modular PCM elements working together with Passive Haus techniques have demonstrated their flexibility. This paper presents a new, efficient, and sustainable modular solution for PCM-based building envelope regeneration projects implemented jointly with Passive Haus strategies and Nature-Based Solutions (NBS) at street level. The efficiency of the proposed strategy is demonstrated though a simplified Digital Twin of the Benicalap neighbourhood in Valencia, Spain. The model simulates the climate evolution at the neighbourhood level, and can be used in any urban background to obtain a new carbon footprint which is then used as the main criterion for joint impact assessment of the proposed modular PCM-based building envelopes.
... The model, or digital twin, of the physical neighbourhood starts with the cadastral digital information which is developed into a digital entity using the ArcGIS Pro 2.9 software from ESRI (Redlands, CA, USA) and following the process developed by the authors of [18]. This model has been adapted to include all building-related parameters (according to their heritage status) for a simplified LCA analysis [19,20], which is required for predicting building energy performance from environmental conditions. ...
... CEA is selected due to its excellent acceptance and accuracy for the energy exchange evaluations, including finally the related CO 2 footprint for building construction and use [20]. The Benicalap digital twin described here obtains the overall energy performance balance and associated carbon footprint for all the buildings in the neighbourhood under normal occupancy conditions and using the average climate adaption measures evaluated in [38]. ...
Starting from historical environmental records of the Benicalap neighbourhood in Valencia, this paper presents an energy model contributing to the assessment of carbon-neutral city policies for several nature-based solution (NBS) pilots extended to the neighbourhood level and combined with building façade renovation proposals. Accurate monitoring of several NBS pilot strategies was studied to validate a computational-fluid-dynamic (CFD) microclimate flux (both storage heat flux and latent heat flux) model, allowing a joint understanding of humidity and heat dynamics for the pilots under study. When expanded at a neighbourhood level, the combined effect of NBSs and energy dynamics (from buildings and vegetation) on neighbourhood microclimates is used to assess the optimal combination of urban renovation policies for energy efficiency and consequently carbon footprint reduction.
