Moving towards sustainable urban development leads to applying new forms of drainage, which provide multiple technical and social benefits to the community. However, in countries like Chile, there is still a large gap regarding methodologies to assess the social sustainability of projects in this area. Using a qualitative content analysis applied to experts’ interviews (n = 11), this study aims at (1) identifying metrics to assess the social sustainability of urban drainage systems; (2) identifying challenges for the implementation of such metrics, and (3) proposing changes to the current system, to assess urban drainage systems that enhance the integration of social sustainability within these systems. The results show that experts proposed metrics that may assess social sustainability, but in practice, these metrics are difficult to quantify. In terms of challenges, the fragmentation of responsibilities from organizations that are involved in managing urban drainage systems may complicate the use of new social sustainability metrics. Ultimately, it is suggested that an institution is created that can manage urban drainage systems using an integrative approach, to account for the benefits of social sustainability of urban drainage systems. These results can be used by authorities and decision-makers who work with urban drainage systems, to move towards methodologies that consider the benefits of social sustainability.

At a time when the planet is showing clear signs of the overload of our ecological footprint, when the demand and services of nature far exceeds its biocapacity, it is urgent to generate a turning point, as there is sufficient scientific evidence to affirm that we are approaching the dangerous limit of the point of no return.

Alternative materials, such as cement-stabilized earth blocks (CSEB), provide new opportunities to make environmentally friendly envelopes. Earth-based construction materials are easy to obtain, abundant in nature, and their use minimizes environmental impacts and improves the thermal performance of bricks. In this work, the thermal properties of CSEB are analyzed, to evaluate their efficiency for building envelopes. It is experimentally determined that cement percentages are between 3% and 9% for the manufacturing of CSEB for non-bearing masonry. The moisture content should be less than 20%, to avoid significant increases in thermal conductivity. Wall thermal resistivity and inner and outer thermal resistance are also determined by means of passive building thermography measurements. The different CSEB wall compositions of experimental dwellings under real use conditions were monitored during the winter, and from this, thermal transmittances were established for the walls of 1,219 W/m2K to 1.599 W/m2K The results obtained allow determining the relative efficiency of each building envelope type in avoiding heat losses.

Using the physical construction of a prototype as an educational tool is not new, although it can be innovative in the current context of conceptual renewal linked to sustainable development. At the School of Architecture of Seville, there is a great research tradition on sustainability, but little is extrapolated into teaching. There is also a need for a significant improvement in education from the methodological point of view. In this sense, competitions provide an opportunity that defines a potentially rewarding situation for educational innovation. From this starting point, this research aims at verifying how the construction of a full-scale prototype, as an active educational methodological strategy and following a bioclimatic design methodology consolidated in said School of Architecture, allows achieving great results both in educational and bioclimatic terms. The educational methodology brings together the following guidelines: the workshop as an integrating environment for architectural learning; the construction of a prototype as an educational situation that transcends the architectural; the conceptualization of new challenges marked by sustainability and their practical and effective application to the architectural project, design, and architectural construction. All the tools are valuable and effectively respond to shortcomings detected and internalized in teaching-learning, and, consequently, architectural activities.

The wood-based housing market in Chile requires a complementary review that considers the competitive advantages of this material regarding its technical features and structural properties, to strengthen compliance with the Chilean General Urban Planning and Construction Ordinance (OGUC, in Spanish) and the Sustainable Building Codes. The purpose of this research was to develop an Integrated Sustainability and Safety Indicator (IISS, in Spanish), which integrates regulatory, social, territorial, and environmental aspects, considering (1) presentation, (2) sustainability, and (3) safety variables for wooden houses. For this, information was collected from 230 wood construction companies located between the regions of Valparaíso and Los Ríos, in Central Chile, where product presentation and safety were highlighted as inputs to calculate the IISS. This integration resulted in a classification of useful technical indicators to promote wood use as a construction option that prevails over or complements other building options.

Throughout the 20th century, the construction industry has been using large quantities of concrete. Consequently, the demand for natural aggregates has increased, making it necessary to counteract their use. In this context, this work aims at presenting a literature review of the use of lightweight materials to produce low-density concrete, whose thermal insulation is mainly made using lightweight aggregates. In this framework, 52 articles indexed between 2017 and 2021 in the Scopus database were reviewed. The results revealed that, by employing ceramsite sludge as an aggregate, a density of 1,251 kg/m3 can be obtained and, with expanded clay aggregates, compressive strengths from 17.7 to 66.1 MPa can be obtained. In conclusion, it was determined that the use of lightweight materials in concrete production can reduce its density, in addition to contributing to the reduction of environmental damage.

Buildings represent 40% of the world's energy demand and CO2 emissions. In Argentina, buildings are responsible for 40% of the total annual energy consumption. The problem lies in an imbalance between the need to provide a high quality of life and comfort in office spaces, and the high energy cost required to meet that goal. Both a high comfort level and energy savings represent two objectives to be achieved. In this sense, this paper proposes a new methodology that combines onsite measurement with mathematical simulation tools. Innovative techniques and models are incorporated to make the tool, applying thermal-energy multi-objective optimization, which operates dynamically during working hours. The results show significant savings in energy consumption regarding cooling office spaces in the summer, from 57.5% to 83.3%, together with an increase in the thermal comfort quality, with improvements between 4.7% and 29.4%.

The interest in making research more dynamic within universities has evidenced the need for the creation of research groups. In this sense, the purpose of this article is to establish a relationship between the data obtained from bibliometrics and the profile and interest of Architecture Faculty researchers, to identify research niches that guide their work. This research was carried out through a systematic review and use of scientific production bibliometric tools in the last five years within the architecture domain in the SCOPUS database. The research made used five steps that guided the process: search; evaluation; synthesis; analysis; and monitoring. Through the search process, 1,465 scientific documents were obtained, analyzed with the Bibliometrix web application using indicators that allowed obtaining the results, to connect them to both teaching interests and profiles. The analysis identified that sustainability, design, and energy efficiency are topics of interest and constitute trending topics to promote the work and the constitution of research groups.

Few studies focus on researching the potential of sustainable buildings to promote the sustainability of their occupants. Therefore, this study aims at analyzing the use of LEED credits, with the intention of promoting pro-environmental behaviors. The methodology is exploratory in nature, with a descriptive logic, and comparatively analyzes LEED-certified office buildings [Argentina (n = 351); Chile (n = 494); Colombia (n = 432); and Peru (n = 282)], between 2012 and 2020. The results revealed that the most used credits were: "Access to Public Transportation", (99.34%); “Surrounding Density”; (98.34%); and, “Tenant construction and design guidelines”, (96.53%); and the least used ones were: “Enhanced commissioning”, (44.30%); "Daylight" (31.31%); and, "Controllability of systems", (7.53%). It is concluded that those who choose to include the occupant in the design, choose to intervene in the culture, while those who choose not to include them, choose technology.

In recent years, energy consumption from electrical devices to foster air movement in regions with warm climates has risen, with the resulting negative impact on the environment. The purpose of this paper is to evaluate the performance of a solar chimney used to induce natural ventilation in a closed space, under the weather conditions of the hot humid Mexican climate. For this purpose, CFD simulations were run using the RNG k- ɛ turbulence model and the DO radiation model, considering only natural convection phenomena. The solar chimney performance was evaluated, comparing the results of the simulations with experimental measurements, analysis which showed a good match. Temperatures of up to 46.5%°C in the air within the chimney, and of 77.1°C on the absorption plate, were obtained, results that allow verifying the influence of the heat discharge phenomenon by the natural flotation of air in the chimney.
