Climate change is globally one of the most relevant problems of the 21st century and despite strategies that seek to minimize its consequences, it is an irreversible reality. Therefore, it is pertinent to analyze its impact on Colombian architecture, specifically on Social Housing (SH), the type of building most frequently built in the country. The purpose of this research was to get to know the thermal performance of current SH, in relation to climate change, based on a standard model for the most populated cities in Colombia, namely Bogotá, Medellín, and Cali. This model was made using computer simulations in three future scenarios (2030/2050/2080), which allowed diagnosing how climate change will affect the thermal comfort of the occupants. The results show that, of the total number of scenarios evaluated (576), only 18.9% are in an acceptable range of time in thermal comfort (>70%). This indicates that most of the SH currently built in Colombia do not provide thermal comfort conditions either under a climate change scenario or in the current scenario, since in both situations the favorable cases represent a low percentage with respect to the total number of cases evaluated.

Education has changed thanks to technology. Therefore, more than sharing knowledge, the aim is to promote creativity through tools and methods. This paper aims at analyzing the suitability of the inverted classroom in the teaching-learning process of bioclimatic architecture in the context of a pandemic or traditional classroom teaching. The methodology has a qualitative approach, a non-experimental design, and an exploratory study. The results confirm that the students deduced the theoretical knowledge and competencies they would have received in a linear way in the traditional classroom. In conclusion, it is suggested that the difference between this teaching practice and a traditional one was in making the theoretical derive from the practical, activating a didactic transposition process that not only simplified knowledge but was based on generating transversalities from the variables involved in the learning process.

Faced with the qualitative and quantitative deficit of educational infrastructure in Peru’s rural high Andean areas, in recent years the Peruvian State has been investing in and supporting modular solutions, seeking efficiency in the construction processes. The specific proposal, with special emphasis on bioclimatic design, is the "Prefabricated Frost-type Modular Classroom". However, users have been expressing discomfort with these new facilities. This study shows the measurement process carried out on a built module, which allowed calibrating and validating the model using simulation software, to propose improvements in the design that may contribute to future constructions. Taking the adaptive thermal comfort model as a reference, it was confirmed that indoor temperatures were below thermal comfort limits in the early hours of the morning and well above them close to noon, by around 6 ºC and 7 ºC respectively. With the application of complementary bioclimatic strategies, it was possible to considerably improve indoor thermal conditions, although not enough to reach comfort early in the morning. This is because the night-time outdoor temperatures are very low, the building is uninhabited all night long, there is no thermal mass in the envelope, and there are no active solar systems or mechanical air conditioning.

Timber housing is a sustainable bioresource-based alternative to traditional construction with masonry and steel, and recent studies have shown that this sector in Brazil has hundreds of timber housing SMEs. This exploratory study, while analyzing this population, evaluated the profiles available on Instagram®, observing their business strategies and what they have disclosed to clients on sustainability benefits and issues. All the available corporate profiles were surveyed, and a significant sample of about 80% of a sector was compiled, from a market currently formed by over 400 companies. However, about 70% of these Brazilian companies still do not adequately explore sustainability issues in their timber housing products and service, evidencing an incipient scenario. Moreover, there is a clear opportunity to leverage the arguments posted on their Instagram® profiles as an affirmative awareness strategy. Although some justifications were suggested to convince domestic customers to consider timber housing, this virtual market has a lot of room for improvement.

Access to housing in low-income sectors brings up the need for a relevant reflection on Latin America. In this context, a wood-based Modular Housing Solution (MHS) has been developed in a neighborhood on the outskirts of CABA called La Plata, oriented to a housing improvement for working-class sectors, and managed by a labor cooperative, the university, and the scientific-technical sector. The objective is to evaluate the thermal and light behavior and the airtightness conditions of the building envelope of a wooden MHS in the La Plata district in a warm-temperate climate. For this purpose, first, indoor and outdoor monitoring (temperature, relative humidity, and natural lighting) was carried out, then the solar air heaters were evaluated, and finally, digital thermography was performed at night. The results show favorable daytime lighting performance and good daytime thermal response in cold weather. However, there was also room for improvement, such as the need for thermal conditioning at night, improvement of the airtightness of the envelope, night ventilation in warm seasons, reinforcement of shading, and thermal insulation.

The conventional approach to achieve thermal comfort generally focuses on modifying the setpoint temperature in fully air-conditioned buildings. However, the adaptive thermal comfort approach is an alternative that considers the interaction between buildings, the local climate, and the users to allow significant improvements in energy savings. This paper analyzes the feasibility of implementing adaptive thermal comfort strategies, comparing adaptive models based on the ASHRAE 55-2020 Standard and a regional model for the tropical climate typology of Mexico, and contrasting the results with the static approach. Thirteen locations in the State of Campeche were thermally analyzed, seeing that the ventilation strategies are applicable throughout the State and that both models ensure improvements in energy consumption. In addition, the results suggest that it is necessary to develop more local adaptive models to propose strategies with better potential impact in the region.

Today, the climatic consequences caused by greenhouse gas (GHG) emissions are evident and are on track to see global warming of 2.7 °C by the end of the century. The energy dependence of buildings is one of the main causes, since they required 50% of global energy consumption in 2021 just for heating, making it necessary to implement passive bioclimatic air conditioning systems. This work documents the use in vernacular dwellings in Queretaro, Mexico, of an efficient attic-type passive system, called "tapanco", consisting of an inert air chamber that functions as a thermal buffer. A case was evaluated by applying measurement methodologies with thermo-hygrometers, complemented with thermography and thermo-wind simulation. The findings of adequate hygrometric indices, fostered by the system, make it a relevant alternative for a passive solution in future bioclimatic architectural design, to reduce adverse energy and climatic indices.

Faced with the constant natural disasters in the Andean regions of Ecuador, several housing solutions have been proposed. However, these do not consider the user’s thermal comfort or the environmental impact they generate. This research addresses this issue from a bioclimatic perspective through an emerging housing model in an Andean climate, oriented to ensuring thermal comfort and reducing the environmental impact of the construction. The analysis focuses on indoor temperature and the Total Embodied Energy (EET) of the housing model. The methodology is divided into the definition of the model and strategies, on one hand, and, on the other, the analysis of these parameters through simulations and calculations. In addition, a comparative analysis with other studies is carried out. The strategies defined were solar gain, thermal mass, compactness, local-recycled materials, and modulation. The results show that the proposed model passively reaches comfort temperatures, and that the EET (2135.38 MJ/m2) is lower than that of other social housing.

The aim of this work is to determine the thermal conductivity of different earthen constructive elements produced with materials typical of the central-eastern part of the Province of Santa Fe (Argentina), and to evaluate their suitability to be used in the construction of envelopes that comply with the thermal insulation requirements of the corresponding National Regulations. For this purpose, test specimens were made following the different earth construction techniques used in the region (compressed earth block, adobe, rammed earth (tapia), wattle and daub (quincha), and plaster), and their thermal conductivity coefficient was measured, with which the thermal transmittance of different earth construction packages was calculated. The results obtained indicate that the earth construction techniques evaluated show, in all cases, a better thermal performance than traditional solid ceramic brick or concrete block walls, with wattle and daub being the technique with the highest thermal insulation capacity.

Passive architectural design strategies have been an effective response to the energy crisis of the 20th century. In temperate climates, their integration results in thermal behaviors that combine indoor comfort and energy efficiency. However, projected future climate change scenarios will not offer the same performances, resulting in such strategies being less effective. The objective of this work is to quantify the relative change in the effectiveness of passive design strategies in dwellings for arid temperate-cold climates (Bwk), taking the city of Mendoza (Argentina) as an example. Regarding future climate projections for warm arid climates (Bwh), using the CMIP5’s RCP8.5 scenario, equivalent to the IPCC’s CMIP6 SSP85 scenario, the results show a 20% decrease in the number of hours in annual comfort, with a 24% increase in the need for passive summer strategies.
