Sebrae MG in Brazil
Faced with a set of pre-existences originally not articulated, the proposal for the building is that of an integrating element in order to create a global restructuring of new accesses and new connections. The party considered the premise defined in the program, which defines the distinction building in two sectors: an administrative and an events sector. The composition of the building is defined by a single volume, an administrative block, on a basis, events.
The site insertion is looking for the reduction of occupation area at the ground floor level. In this story, a large main access plaza was located with the intention of creating a public space through the extension of the promenade, emphasizing the public character of the building. The creation of this was possible with the parking distribution in three levels of underground, which access is on the street with less traffic.
In technical-functional terms, it is structured in a regular multiple expanded metal mesh of 0.625m, sub-module of numerous constructive components. The structural system adopted, in a mesh of 10x10m, is made up of expanded metal beams and concrete columns with precast steel slabs and steel deck. The building is organized in large spans, which is possible due to the use of a three-story steel trussed frame, located in the longitudinal facades of the volume. The mooring and the stiffness are given through transverse metallic profiles.
The external closure of the northwest and southeast facades consists of two layers:expanded metal frames with safety glasses and stainless steel screen with controlled translucency according to the orientation of each façade. The layers, separated by a technical walkway, create a transition space in which there is upward ventilation, generating thermal comfort for the interior space.
The luminous comfort occurs through the light filter and consequent reduction of the incidence of radiation provided by the screen. Finally, the green cover slab guarantees thermal insulation and reduces the demand on public rainwater networks, retaining for some time the water collected volume.
