Housing and its indoor environment influence its inhabitants’ comfort, productivity, and health. For this reason, it is becoming increasingly important to investigate the factors that affect indoor environmental quality. Thus, numerous sustainability assessment systems have been developed to evaluate building performance. This paper presents a model for evaluating the indoor environment of housing located in the Biobio region of Chile, integrating aspects that influence its overall quality. The research methodology proposes a strategy to identify appropriate evaluation criteria and contextualized standards. The application of the model made it possible to identify the level of performance of studio dwellings for each category, namely air quality, thermal comfort, acoustics, and lighting, as well as the overall evaluation of the IEQ. The results reflect that the lowest levels of performance in the three houses were with respect to the acoustic evaluation criteria, while the highest levels of performance were for the air quality evaluation criteria.

This study presents the first systematic regional assessment of how the Historic Urban Landscape (HUL) approach has been understood and applied in Latin American and Caribbean (LAC) cities between 2011 and 2022. The HUL approach is framed as a socio-spatial perspective shaped by historical layering, cultural practices, ecological structures, and contemporary development pressures. A systematic review of academic publications and institutional gray literature (Scopus, Google Scholar, and municipal repositories) was conducted to evaluate both conceptual understanding and methodological implementation aligned with the six steps of the 2011 HUL Recommendation. Findings reveal a clear implementation gap: although awareness of the HUL approach has increased across the region, its practical application remains partial. Steps 1 and 2 focused on value identification and participatory engagement show the highest adoption, while steps 4 and 6 which require interinstitutional coordination and integration into statutory planning instruments exhibit limited progress. Academic and research institutions play a more prominent role than local governments in leading or supporting HUL-related actions, indicating persistent institutional and governance constraints. Results highlight the need to strengthen municipal capacities, integrate HUL-based diagnostics into urban planning systems, and consolidate participatory, interdisciplinary, and multilevel governance mechanisms to close the gap between conceptual uptake and operational implementation.

Cities play a vital role in creating wealth and ensuring the well-being of all their inhabitants. However, major international efforts aimed at fostering fairer, healthier, and a more sustainable world have been compromised by the widespread effects of the COVID-19 pandemic. The objective of this research is to determine key priorities for addressing the pandemic’s impact in both the present and in a future urban context. Therefore, this study applies the Delphi method to a panel of 24 experts in order to identify the most and least important targets from Sustainable Development Goal 11 for post-COVID-19 sustainable urban planning in Cuenca, Ecuador. Out of the twelve targets, only five were prioritized, including “Target 11.1 Affordable housing”, Target 11.3 Sustainable Urbanization”, “Target 11.9 Implement policies for inclusion and property rights”, and “Target 6.3 Improve water quality”. These findings can serve as a foundation for future public policies and strategies for sustainable urban planning of the city.

The cities have developed over time responding to various urban dynamics, in this process have been configured representative images, product of the synergy created between the natural elements of the environment and those built by the communities. The analysis of visuals, materializes a landscape value, not evidenced at the time of planning and design projects for cities with value surroundings; you can take as an example those good practices that other countries have implemented to assess, preserve and protect views such as English Heritage (2011), London View Management Framework (2012) or View Protection Guidelines of the city of Vancouver (2011). The methodological analyzes the view in two stages: the first one strategic points of observation and view basins are identified and described as element integrators – what is seen, and through citizen participation accepts or does not accept the evaluation criteria; in the second, the view is evaluated through the relationship between quality and incidence, giving it an assessment of how fragile it is. The application of the methodology in the area known as El Ejido in the city of Cuenca – Ecuador, has resulted in a total of twentyeight visuals considered relevant. Nine of them, have been analyzed completely, evidencing that there is a view quality very High / High; nevertheless, they are affected by urban actions that generate that the incidence is High and therefore the fragility and vulnerability is greater.
