PHA Consult were the sustainability consultants and MEP Engineer’s for the competition-winning scheme to design a new corporate headquarters for the Banco Ciudad de Buenos Aires, Argentina.
The project was designed by Foster + Partners, working with construction firm, CRIBA S.A. and local architect, BBRCH-Minond. Plans for the energy-efficient building, which will occupy an entire city block in the neighbourhood of Parque Patricios, echo its park-side setting with landscaped courtyards and shaded walkways and will provide a distinctive new presence for the bank in the city.
The scheme occupies the whole site to create an internal campus of ‘villages’, which are connected by circulation routes and external landscaped patios and are unified by a flowing roof canopy. The entrance plaza is sheltered by the deep overhang of the roof, which is supported by slender pillars. A full-height atrium directs circulation into four tiers of terraced office spaces, all of which have direct views of the park. Based on an eight-metre-square planning grid, the generous light-filled floor plates allow the work spaces to be flexibly planned.
The plans form part of a wider regeneration initiative in the barrio of Parque Patricios, a formerly light industrial area to the south of the city centre, which has been identified by the city’s government as a centre of technology. The design incorporates a number of sustainable features and targets LEED Silver accreditation. These include utilising the exposed thermal mass of concrete soffits with chilled beams for cooling; and reducing energy demands through shaded facades, which are oriented according to the path of the sun, and by encouraging natural ventilation.
PHA Consult are now working with local MEP engineering and LEED consultants GF/estudioGrinberg to develop the competition concept, providing advanced energy and systems modelling to ASHRAE 90.1, natural ventilation simulation, and daylight and glare analysis.
