Researchers credit the Hanging Gardens of Babylon as the first examples of green roofs. Although there is no proof of its exact location and very little literature on the structure, the most accepted theory is that King Nebuchadnezzar II built a series of elevated, ascending terraces with varied species as a gift to his wife, who missed the forests and mountains of Persia, their local land. According to Wolf Schneider [1] the gardens were supported by brick vaults, and under them, there were shaded halls cooled by artificial irrigation of the gardens, with a much milder temperature than the outside, in the plains of Mesopotamia (present-day Iraq). Since then, examples of green roofs have appeared all over the world, from Rome to Scandinavia, in the most diverse climates and types.

Nevertheless, inserting plants on roofs is still viewed with suspicion by many, as they are thought to be costly and difficult to maintain. Others, however, argue that the high implementation costs are quickly offset with savings in air conditioning and especially that occupying the building's fifth façade with vegetation is, above all, a rational solution. In any case, the question remains as to how green roofs can really help with climate change.

One of the biggest names in Brazilian and worldwide architecture, Paulo Mendes da Rocha, passed away at the age of 92. As his son Pedro Mendes da Rocha reported to ArchDaily, the architect was hospitalized in São Paulo due to lung cancer and passed away at dawn on Sunday, May 23, 2021.

Paulo Mendes da Rocha will be remembered for the great formative role he had. His architectural creation debated life above all, raising questions and challenging ready ideas and conformity. He consolidated an influence short of language or aesthetics, formed mainly by the way of acting and thinking, in which each project was an opportunity for transformation. His ideas and designs overflowed the limits of the program, place and materiality, always bringing a new point of view to achieve revolutionary simplicity.

Ventilation serves two main purposes in a room: first, to remove pollutants and provide clean air; second, to meet the metabolic needs of the occupants, providing pleasant temperatures (weather permitting). It is well known that environments with inadequate ventilation can bring serious harm to the health of the occupants and, especially in hot climates, thermal discomfort. A Harvard University study demonstrated that in buildings with good ventilation and better air quality (with lower rates of carbon dioxide), occupants showed better performance of cognitive functions, faster responses to extreme situations, and better reasoning in strategic activities.

It is not difficult to see that ventilation plays a vital role in ensuring adequate air quality and thermal comfort in buildings. We have all felt it. But when we talk about ventilation, a light breeze from the window might come to mind, shifting through our hair and bringing a pleasant aroma and cooling temperature that brings fresh air and comfort. In mild climates, this experience can even be a reality on many days of the year. In harsh climates or polluted spaces, it could be quite different.

Lina Bo Bardi, one of the most important architects of Brazilian architecture, was selected as the recipient of the Special Golden Lion for Lifetime Achievement in memoriam of the Venice Biennale 2021 (also known as the Biennale Architettura 2021), which will open to the public on Saturday, May 22nd, 2021.

Little has been said about the contribution of scaffolding to the history of construction. These structures are generally treated as mere equipment and, as a result, their records are very scarce. Without scaffolding, however, it would be almost impossible to construct most of the buildings we know. Scaffolding allows workers to reach and move materials at difficult points in a construction, providing safety and comfort. But in addition to its role as a support structure for buildings, we have also seen that scaffolding can be used for mobile, temporary, and even permanent structures. Below, we explain its history and possibilities for use.

The pillar has adorned many of the greatest monumental examples of Western architecture since antiquity, from the Doric columns of the Parthenon to the Corinthian capitals of the Pantheon portico. In the West, the legacies of these classical forms have permutated over the centuries and into modern times: the Doric columns of the Lincoln Memorial, the Ionic columns of the British museum portico, and the Villa Savoye’s pilotis are just a few examples of the classical column’s continued transformation and use over the last few centuries. Today, the round pillar continues to be used in modern design, both functionally and aesthetically. Below, we look into these elements in more detail, including their materials, construction, structural qualities, and several contemporary examples of their use.

Hydraulic tiles are tiles produced entirely by hand with cement-based raw materials. Created in the mid-1800s in Spain, and widely used in Europe and America, it is a versatile option that can not only be applied in public areas, such as squares and sidewalks, but also interiors, including floors, walls, and furniture. Their versatility stems from the fact that they are highly customizable, from their colors and patterns to their geometry and dimensions. Read below a mostly technical explanation of these tiles, their manufacture, and their installation.
