“…Similar tools have been developed in the Basque country [15] and in the metropolitan area of Barcelona [16]. The search for methodologies that can better inform decision making in residential rehabilitation constitutes an expanding field of research [17,18]. Most scientific studies that have successfully provided tools for the selection of priority areas have a top-down approach, based on the analysis of very complex secondary data sources and the detection of areas of high vulnerability.…”

The promotion of rehabilitation is an urgent necessity in today’s consolidated cities, both due to the need to update their buildings to achieve habitability and safety standards that are required nowadays, as well as to stop the deterioration of buildings in vulnerable environments, where paradoxically the obtainment of economic resources to invest in building maintenance and upgrade is scarcer. Decision making on the delimitation of areas in which the need to invest is higher is extremely complex and often relies on large secondary data studies that are contrasted with local stakeholders’ intuition and knowledge on the ground. Usually, rehabilitation aids are directed to relatively large areas, where a certain need may be found. However, these areas are often excessively wide and specific needs that would require special focus can be diluted in the whole. The current trend of area-based and site-specific rehabilitation programs calls for precise and focused data studies and methodologies. The research presented here provides a methodology for the selection of priority areas to promote rehabilitation in the context of Barcelona’s vulnerable neighborhoods. The selection methodology combines primary and secondary data with a very high level of disaggregation that identifies where the needs are greatest, and it also provides a tool that is still based on primary disaggregated data for the delimitation of areas. The results obtained highlight specific priority areas such as parts of the Raval, Carmel and Besòs-Maresme neighborhoods within larger zones that had been previously defined as vulnerable. The proposed methodology seeks to provide tools to foster evidence-based decision making, thus improving both the understanding of reality and its spatial distribution through data mining techniques and data visualization.

“…Further data analysis was performed by the statistical tool of cluster analysis based on the recognition of homogeneous groups and defining building types that had similar characteristics and performance. This method was explained in detail in previous publications [17]. The main characteristics analyzed were the age of the building and the volumetry and the materialization of the facade.…”

Energy refurbishment of school buildings is a priority regarding both energy consumption in buildings and improving comfort conditions for sensitive young occupants. During 2016–18, a group of teachers and associates from the Faculty of Architecture, Mechanical Engineering, and Electrical Engineering from the University in Belgrade participated in the project “Energy efficiency in public buildings” in cooperation with GIZ (Deutsche Gesellschaft für Internationale Zusammenarbeit), University of Belgrade, Faculty of Architecture and Ministry of Mining and Energy of the Republic of Serbia. During 2016 and 2017, a comprehensive survey and database of public buildings were conducted by the local community. The focus of the research was the facilities of children’s institutions, and detailed data were collected to determine the current building stock conditions, energy consumption, and possible improvements. This paper presents the methodology of the project based on defining the typology of buildings, determining the representatives of the characteristic periods of construction, and analyzing their energy performance. Five possible scenarios were considered: designed condition, existing state, and three levels of a building improvement. The main goal of this project was to ascertain the entire fund for school buildings, indicate the potential for energy savings of this type of public building at the national level, and use this as a starting point for developing strategic decisions and further energy efficiency policies. This paper presents the complete results of the research on school buildings in Serbia, their energy performance, and possible energy savings. Key findings show that a great majority of schools are in a poor state in terms of their energy efficiency, but at the same time, there is a large potential for improvement of building envelope, HVAC, and lighting systems, which can cut the current energy need for heating to up to 80%.

“…Such methods, when unsupervised, often allow buildings with different key features to be included in the same typology simply because of the proximity among the (selected) dependent variable (usually the energy use intensity). Taking into account that in common planning practices the same renovation interventions are assumed for buildings of the same typology since they are fairly represented by one archetype or ambassador building [8,[22][23][24][25], an additional limitation for any (supervised) classification algorithm would be to ensure that buildings of the same cluster have similar key features, which are related to the energy interventions to be tested in a further step. For instance, if the replacement of an oil burner is included in the set of interventions tested for a typology, then all buildings of the same typology should have an oil burner for heating purposes in their existing situation.…”

According to the latest energy efficiency European directive (EED 2023/1791/EU), the expected energy renovation rate of at least 3% of the buildings’ floor area each year towards nearly zero-energy buildings (nZEBs) is extended to include public buildings not only of the central government (as per the first EED 2012/27/EU) but also of regional and local authorities. This poses a great challenge, especially for Municipalities that often manage large building stocks with high energy demands. In response to this challenge, this paper presents the application of the so-called “typology approach” for conducting public buildings’ energy renovation plans at the local level. A computational survey is initially introduced to decide the optimal set of building-stock clustering criteria among all possible combinations, involving the minimization of the RMSE index regarding the primary energy consumption of each building. For a representative building from each identified typology, the key performance indicators (KPIs) are computed for alternative energy-upgrading scenarios. Exploiting the IMPULSE Interreg-MED project tools, the KPIs from each representative building are at first extrapolated to all buildings of the examined stock and, finally, a gradual energy renovation plan is automatically produced based on user-defined decision parameters including the required annual renovation rate. The methodology is applied for the case of the Municipality of Hersonissos in Greece. For the specific 44-buildings’ stock it was found that the optimal clustering set included four criteria, building use, construction year, heating, and a cooling system, leading to 15 building typologies. Finally, assuming a 7% renovation rate per year, a 12-year gradual renovation (nZEB transformation) plan is obtained foreseeing an 85% CO2 emissions’ reduction.
