Within the canonical architecture, Vitruvius' treatises are the first treatises known. In addition to discussing the intellectual and cultural formation, interests, and sensitivity of the architect, or the "sacred" triad of architecture - venustas, firmitas, and utilitas (beauty, solidity, and functionality) - the treatise describes a design method, a kind of manual for Roman construction at the time. Complex and sophisticated, Roman architecture presented a variety of buildings with several functions. Among them were thermal baths, which did not escape Vitruvian prescriptions.

Climate issues have been the main topic of discussions about the future of cities, but they are certainly not new. The warning about human irreversibility on the planet has been part of scientific discourse since the 1980s. Faced with increasingly frequent environmental urgencies, Donna Haraway, in her book Staying with the Trouble: Making Kin in the Chthulucene, suggests a change in attitude on the part of humans to ensure not only partial environmental recovery but the species' survival.

Architecture involves mobilizing several aspects of the environment where the building is located: the socio-cultural, political and economic context, aesthetics, legislation, and functionality. Functionality includes use efficiency, occupancy, and comfort. Laurent Troost's work has shown the articulation between these various factors, with particular attention to comfort, especially thermal comfort. His projects prioritize natural ventilation over artificial air conditioning, which has become almost mandatory in current city models.

Environmental issues urgency and increasing temperatures on the planet are nothing new. There are many factors contributing to environmental degradation. However, two can be viewed as representative of critical points in the current world system: plastic and waste disposal, better known as garbage.

The environmental crisis cannot be attributed solely to these two examples. They are used here as examples to mobilize issues involving multiple agents, materials, and diverse methods. These issues lead to devastating consequences, increasingly irreversible.

In theory, architecture is separate from art. Some even argue that there is a hierarchy between the two. Fortunately, Vão is an example of how this separation doesn't need to exist and how having a hierarchy between them is unproductive for both sides. Founded in 2013 by Anna Juni, Enk te Winkel, and Gustavo Delonero in São Paulo, the office develops architectural projects fueled by artistic thought. It also develops artistic works on an architectural scale.

Housing is one of the primary aspects of the architecture profession. There are many ways to explore it, from a subordinate program such as a religious cloister to the splendor of a single-family home. Luis Fernández-Galiano is torn between the "waste" of a low-density area in this type of housing and its seductive formal charm. He reminds us that high-density collective housing, such as apartments, makes more sense in an urban context.

The construction of Brasília is a significant achievement in history and architecture. The Brazilian modernist movement definitively established Lucio Costa and Oscar Niemeyer as their representatives. It led the modernist city to be tested as the new urban order. Nevertheless, the city did not emerge alone, nor was it completely utopic, modern, or modernizing. Alongside the new capital, planned and organic neighboring cities were built.

Light is part of various disciplines, shaping the world as we know it. In physics, it serves as a measure of speed and makes vision, and the recording of images by the eye and camera lens possible. Throughout art history, the representation of light - or its absence - has guided secular movements in various manifestations with equally different techniques and supports. This means that light - and its derivative shadow - can create environments, atmospheres and sensations, which can be perceived in objects and spaces. Light is also a part of architecture.

Cemeteries are among the architectural programs with the greatest symbolic value. They suggest rituals, rigor and solemnity while offering some comfort or hospitality, if not for those who bid farewell to their loved ones, at least to "guarantee" a dignified afterlife for those who have passed away. The San Cataldo Cemetery, designed by Aldo Rossi and Gianni Braghieri, fulfills the first part of the previous statement. Partly because the project was not entirely built, austerity and empty spaces predominate. But when considering the proposed project, perhaps the aridity would remain, and the harshness would be felt more forcefully. Composed of buildings with almost abstract, pure shapes, without noble details or cladding, the cemetery project is a good example of Aldo Rossi's production at the time of its conception, around 1970.

Within various - if not all - architectural programs, there is a function that is an essential and common requirement: the bathroom. A residence, office, commercial space, theater, museum, religious space, park, or school can only be designed with it. In some countries, public toilets are part of urban infrastructure like public transport or waste collection. A fundamental human right, although denied to a considerable portion of the global population, the toilet follows a historical evolution. Modernity brought with it the separation between public and private, and the room became increasingly reserved in Western society.
