In the context of Algerian energy and environmental concerns and its aspirations for energy transition, this article examines the pre- and post-state of a multi-family residential building in the city of Skikda, in northern Algeria, utilizing the UBEM reduced-order approach, alongside QGIS, CEA and METEONORM tools. Primarily focusing on the building's solar exposure, energy aspects, and environmental considerations. Six hybrid renovation scenarios were considered then, and assessed for their contribution for energy savings and ecological improvement. The main results revealed that 87% of annual energy requirements were related to heating and hot water, which are supplied by a natural gas system, a source of various types of greenhouse gases, which suggested the use of triple glazing, with or without two selective low-emissivity coatings only, or be combined by changing hot-water supply system to an electric one, alongside the installation of the hybrid PVT panels on the south façade. This triple glazing was joint in another scenario by integrating the same type of panels on the roof alongside a seasonal thermal energy storage system. This latter scenario being the best in terms of energy and ecology, and making the building highly performant in both aspects.

The presence of children in public spaces has become a trigging reality to consider, because children use these spaces to play without taking into account their suitability for such activity. This article tackles children's use of the public square as a play space in Batna Province, Algeria. We adopted a mixed methodology that combines qualitative and quantitative elements to study the use and quality of a space used by children. The qualitative component allows us to explore human interactions and the environment, while the spatial analysis gives us an understanding of the physical layout of the context. The quantitative component aims to evaluate the opinions and preferences of children’s carers. To carry out this study, we conducted a field investigation, including direct observation on the site and interviews with children's carers in the square to find out their assessment and opinions on the quality of the space and its use. Moreover, an analytical study of the square plan was also implemented at the spatial and functional level, in order to reveal all the changes in space before and after use by children. The results of the study confirmed the lack of ease and flexibility of this space for use by children, and the results of the interview emphases the achieved findings, because the public space did not take the child as a user of it at all, neither in terms of space, nor planning and equipment, which led to falling into excessive use of it that resulted in lots of problems.

The trend of housing quality has become more intricate and has expanded to encompass all aspects of habitat. There are several significant challenges related to improving housing, both socially and in terms of economic and environmental considerations. Discussing the quality of new production methods requires an analysis based on various traditional criteria, using convenient indicators such as cleanliness, stability, safety, comfort, durability, flexibility, and aesthetic appeal. The principal aim of this study is to provide an objective assessment of the quality of Participative Subsidized Housing (LPA) in the municipality of EL-Khroube in Algeria. The methodology employed integrates a field survey and a resident questionnaire to appraise the comfort level offered by this housing type as well as the level of resident satisfaction. The results of the on-site observation indicated that the living environment does not offer an adequate level of comfort. This finding was corroborated by the questionnaire results, which revealed a prevailing sentiment of dissatisfaction among residents. This dissatisfaction can be attributed to issues pertaining to interior comfort and a dearth of local infrastructure and facilities. The results of this study will assist housing stakeholders in enhancing this mode of production through a collaborative and participatory approach.

As urbanization continues to shape the world's landscape, concerns have intensified over environmental degradation and depletion of natural resources. Accordingly, international agendas emphasize managing urban sprawl for inclusive, resilient, and sustainable cities. On this basis, this study consists of exploring the nexus of urbanization and advanced technologies following a methodological approach based on a bibliometric analysis using the Dimensions Database to analyse research related to urban sprawl and LULC Changes from 1994 to the recent years; and a systematic review to synthesize existing literature on different methodologies integrating GeoAI technologies and LULC Analytics in the process of monitoring landscape, which optimizes Urban Planning and empowers predictive modelling to monitor environmental changes, therefore, promoting intelligent decision-making and inclusive growth via enabling the creation of targeted policies that address socio-economic disparities, environmental sustainability and infrastructure enhancement. By improving comprehension of scientific concepts, this article aims to fill the knowledge gap between urban studies and remote sensing using machine learning.

Current patterns of urban expansion are mostly considered as impulsive, leading to numerous negative consequences for our biosphere. This disturbing fact has not gone unnoticed in the sprawling oasis cities of the Algerian Sahara, where palm groves are the primary victim. Furthermore, any approach taken to preserve oasis ecosystems requires considering ecological variables. In this perspective, the present study seeks to highlight the spatial growth process of the Laghouat oasis in southern Algeria, during the period 1986 - 2019. The methodology employed is based on the supervised classification of four Landsat satellite images to initiate a cartographic analysis and a landscape quantification of the land use evolution. The analysis is focused on two LUC classes: built-up areas and palm groves. The results of the cartographic analysis highlighted two completely opposite spatiotemporal trends: a significant growth of built-up areas, against a considerable decline in palm groves. The monitoring of the landscape metrics also revealed two different behaviours: growth by densification and elongation of the urban fabric, versus progressive morcellation and fragmentation of the palm groves. These findings pointed to the negative impact of uncontrolled extensions on both the palm groves and the overall oasis ecosystem. This research highlighted the importance of landscape metrics in assessing various forms of spatial urban growth and may support urban planners in choosing the optimal solutions for oasis sustainability.

This study is dedicated to exploring the Ksurian heritage of the Algerian Sahara, aiming to reveal the abundance and variety embedded within each ksar. Employing a comprehensive analytical approach, we meticulously examine four fundamental aspects: the urban layout, the dwellings, the materials utilized, and the construction techniques employed. To accomplish this research, extensive field visits were conducted, encompassing photography, on-site surveys, and engaging discussions with experts to gain profound insights into the distinctive characteristics of each region. Our findings unveil a remarkable and diverse heritage, exhibiting variations from one region to another, ultimately reflecting the unique traditions and capabilities of the Saharan population.
