Harmonizing the urban fabric
这座办公楼位于布宜诺斯艾利斯飞速变化的巴勒莫区 (Palermo) 中心，使得我们想象在南美热带地区的特殊温润气候中工作的新方式。这座城市继承了西班牙殖民时期的城市结构，这是一种宏大的正交结构，从布宜诺斯艾利斯市中心一直延伸到郊区。该网格由常规街区组成，每个街区由8.66 m宽的地块组成。巴勒莫区是博尔赫斯作品中描述的郊区。 在布宜诺斯艾利斯城市扩张并腾飞时，这个长期被忽视的街区成为了过去十年来城市更新的主要地带。
异质性发展是经济繁荣时期与严重的经济危机之间相互作用的最终结果，同时也伴随着城市法规的变化。建筑环境的三维结构结合了1960年代的casa chorizo（“香肠房”）、车间、老旧工业建筑和高层公寓的建筑。Summers项目的业主在与Soler街区相隔的一个此类地块的中间，向Architecturestudio提供了一个空地。 该场地由两个相邻的地块组成，总宽度为16.32 m，不同高度的建筑物并排排列，其中一个建筑物超过了法规允许的最大限制。
This office building, situated in Buenos Aires in the heart of the rapidly-changing Palermo district, allowed us to imagine new ways of working in the special climate in this temperate region of South America. The city’s urban structure, inherited from the era of Spanish colonization, represents an immense orthogonal fabric that has run riot from the center of Buenos Aires to the outskirts. This grid is made up of regular blocks, each consisting of 8.66 m-wide plots. The district of Palermo was a suburb described magnificently in the work of Borges. The neighborhood, which was long overlooked while Buenos Aires expanded and took off, has become the theatre of a major urban renewal over the last ten or so years.
The heterogeneous development is the end result of an interplay between good times and profound economic crises, all accompanied by changes in urban regulations. The three-dimensional fabric of the built environment is results from blocks that combine chorizo houses, workshops, old industrial buildings and high-rise apartments from the 1960s. The owners of the Summers project handed Architecturestudio a vacant site in the middle of a block of this type alongside Rue Soler. The site consisted of two adjoining plots with a total width of 16.32 m, with buildings of different heights running alongside, one of which exceeded the maximum limit allowed by the regulations.
A volume sculpted by the constraints of the site
The project evolved out of a contextual study reconciling the morphology of the block, urban regulations, and the building mass’s exposure to solar gain. A new urban regulation gave us the opportunity to start a dialogue with the city authorities. The aim of the discussion process was to remove the blind gables and replace them with new façades. As a result, the dimensions of the building in one of the two plots was authorized to exceed the maximum regulatory height so that it matched the height of the tallest adjoining building. This alignment and the continuity of the façades ensured that there was a harmonious urban integration. The desire for there to be continuity between the different planes of the façades prompted us to link the different volumes, adjoining buildings, balconies and terraces with an envelope defined by a precise set of straight lines and tangentially-connected curves.

A tertiary building with the best comfort conditions for everyone
Following an exhaustive sunlight analysis, the envelope became a double skin consisting of pivoting, screen-printed glass panels 30 cm wide. These regulate the heat input from solar radiation and extend the tertiary floor to the outside while generating a bioclimatic space.

In the temperate climate of Buenos Aires, and in the age of the digital revolution, we imagined a place where every occupant can find the best comfort conditions for working, with a range of possibilities: Work in your office in the traditional manner, isolated from the outside; Open the bay windows fully and – protected by the glass panels – feel as though you are outside while enjoying the comfort of the interior; Arrange a more informal work space on the balcony between the two skins, which is naturally ventilated and protected from disturbance.

A periscope acting as an attractive spinal column
To showcase the link between the different levels of the building, and to create a synergy between the work teams, the nucleus of the vertical circulations – positioned at the epicenter of the building – was designed in the form of a periscope. Thanks to a skylight in the roof and a large urban window, this periscope benefits from zenithal lighting. In addition, it transforms into an architectural promenade. Since it is entirely wrapped in glass blocks, it is lit by natural light, is pleasant to walk through, and is conducive to interactions, exchanges and encounters. Glass tiles also provide natural light in the areas of the office spaces furthest from the openings.

Form follows energy
In our parametric reflection laboratory, we were careful to cross-reference environmental data with the parameters of the project in order to design and optimize our work. The curved façades are derived from a mapping of the solar gain received by each glass panel. Five screen prints designed using force fields reproduce reflections and transparencies. A generative process with a regular pattern introduced a random sequence that subtly enlivens the façade.
At street level, on Rue Soler, the periscope outlines the main entrance of the underground car park. On one side extends the lobby, and on the other is a free space to be fitted out in line with the wishes of the future lessee, serving as (for example) a showroom with twin access points onto Rue Soler and from inside the building.The footprint of the double plot can be seen in the drawing of the building plan. The articulation between two volumes (one of which is six stories high, the other nine) of different depths, together with the balconies extending over the city and the large windows over the middle of the block, helps to maximize the façades of this space that is otherwise narrow.
Architecturestudio’s parametric reflection laboratory was able to express the environmental variables with formal aspects. In a regular pattern, the slats alternate in random order, which subtly enlivens the urban façade. Opening the glass panels – which are organized in groups of four – controls the solar gain both for the interior of the building and for the semi-exterior space in-between. The movement of the panels, the varying degrees of transparency, and the rays of the sun create a living façade. It constantly changes with the seasons and the day. This double skin filters 74% of the solar gain, greatly reducing the building’s energy consumption.
