In most architectural projects, vertical circulation is expressed as a purely functional element, tucked away behind fire-rated doors or an elevator core. However, sometimes architects also use spirals when trying to resolve site elevation changes. Given the right scale, these elements allow for a more artistic formal expression that serves both utilitarian and aesthetic purposes without relying on mechanical lifts or stairwells. Structural systems like cantilevered steel trusses and reinforced concrete decks allow these spiral elements to extend outward as sheltered entry canopies or wind around open central atriums. Functionally, these circulation paths may be expressed in several ways: as stairs like the Itamaraty Palace in Brasilia, or as ramps, which can offer the possibility to reduce mobility barriers for visitors. In both cases, the spiral can provide smooth transitions across varied floor levels while maintaining an unobstructed line-of-sight throughout the program.

On the International Day of Democracy, this year the United Nations revisits a traditional idea within the concept: broad citizen participation in government decision-making. On this occasion, the international body invites reflection on how participation and the inclusion of diverse voices in government decision-making can help build a more equitable society. From a spatial perspective, reflection on democracy can move beyond this vertical framing and instead understand it through encounter. What does it mean for a space to be democratic? How can architecture contribute to achieving the principles historically associated with democracy? In the current context of crisis in political organization systems worldwide, this day serves as a platform to question individualization and authoritarianism through the socio-spatial tools available to us.

If the two outermost transverse beams of the roof slab descended to form the end walls of the main floor, they would align perfectly with the perimeter of the floor slab. Had the longitudinal beams not cantilevered twenty centimeters to support and offset the concrete end walls, there would be no room for the upper gutter, nor would a gap be created in the main floor to indirectly illuminate the interior. If low concrete-block walls had not been raised along the sides of this floor, the facades would lack their two overlapping planes and the constant shadow between them—and, at times, a third, intermediate plane.

Have you ever wondered how an exhibition design is conceived? Or how it coordinates the staging of the displayed content?

Historically, what we know today as a museum began as a place to gather pieces and objects organized by typology. This is evident when looking at images of the so-called cabinets of curiosities or wonder rooms, which organized a vast array of rare objects and species (animal, plant, and mineral) brought back from the great explorations of the 16th and 17th centuries.

Centuries later, these collections began to gain traction, and former palaces transformed their hallways into long, continuous galleries, to which only their guests and residents had access. Later, in the 19th century, the emergence of pavilions dedicated primarily to the display of artifacts brought us closer to the modern concept of museums. We regularly publish various museum projects. But beyond their architecture, have you ever noticed the crucial role that exhibition design plays? Below, we outline some of the key concepts of exhibition design.

Today, August 17, is National Historical Heritage Day, a date that honors the efforts to preserve assets of cultural, historical, and artistic significance across Brazil. This date coincides with the birth of historian and journalist Rodrigo Mello Franco de Andrade, who played a crucial role in founding the National Institute of Historic and Artistic Heritage (IPHAN). Established in 1937, IPHAN is the agency responsible for promoting and organizing the preservation of Brazil's National Cultural Heritage, aiming to “protect and promote the country's cultural assets, ensuring their endurance and enjoyment for present and future generations.” [1]

Physical distance is no longer an obstacle for the world's major museums. Once limited by their geographic locations and accessible only to those who could visit them in person, many museums have now digitized their collections, while others are in the process of doing so—a strategy that broadens reach and, to some extent, democratizes access to culture.

Heritage-listed at both the state and federal levels, Teatro Oficina, designed by Lina Bo Bardi and Edson Elito, is at risk of having its surroundings profoundly altered by the construction of two 100-meter-tall residential towers. The project, led by the Silvio Santos Group, was approved by the National Historical and Artistic Heritage Institute (Iphan) during a meeting on May 29.

The São Paulo City Government has resumed discussions regarding property tax (IPTU) exemptions and discounts for landmarked buildings. Previously debated during the administrations of Gilberto Kassab and Fernando Haddad, the issue is currently the focus of a newly drafted bill. 

The proposal limits the IPTU exemption to landmarked properties located in downtown São Paulo, within a perimeter that is still being defined. It will not apply to properties subject to general zoning restrictions, such as those in historically preserved neighborhoods like Jardins and Pacaembu. 

On this occasion, architect Rodrigo Rieiro Díaz, from the ARKRIT Collective, presents an article that explores how certain contemporary architects have refused to hide building scars resulting from material processes in rehabilitation projects, in a bid to emphasize the pre-existing structure as an aesthetic asset.

While it is true that not painting—or covering with joint covers—the marks of material processes during building adaptive reuse projects represents a financial saving, there seems to be a desire among certain contemporary architects that goes far beyond simply cutting a line item from the budget.

Indeed, there is a contemporary tradition—the reuse of industrial buildings as art spaces—where this practice is common. This model of an exhibition space, halfway between a gallery and an artist's studio and geared toward a young, urban audience, already has a history of at least forty years. Yet there is a certain consecration of the method in its adoption by the city councils of major European cities for their cultural institutions, and in the highly favorable reception of these interventions in academic and professional circles.

Today, it is estimated that in Brazil alone, 30 million tons of waste are deposited annually in landfills, with São Paulo alone sending 14,000 tons of solid waste to these sites every day. [1] Unsurprisingly, landfills occupy vast tracts of land that continue to expand, posing a critical challenge for nearly every city. But what can be done once landfills reach capacity and close? Is it possible to breathe new life into these mountains of waste? What are the possibilities and necessary precautions?

Today, we launch a series of publications showcasing open-access theses and dissertations that address issues relevant to Architecture and Urbanism. We recognized the need to share the remarkable academic output of our universities—which often goes unrecognized—with the widest possible audience.

In this first edition, we present the work of architect Jorge Isaac Perén Montero and his master's thesis entitled "Natural Ventilation and Lighting in the Work of João Filgueiras Lima, Lelé: Studies of the Sarah Kubitschek Network Hospitals in Fortaleza and Rio de Janeiro," advised by Professor Rosana Maria Caram at the São Carlos School of Engineering - EESC/USP.
