Bahá’í Temple of South America by Hariri Pontarini Architects




Born out of an international competition with over 180 entries from 80 countries, the Bahá’í Temple of South America was chosen by World Architecture’s jury of 97 architects and critics as the Best Building of 2010.

A very extraordinary structure whose construction should be complete at the end of 2014 is currently being built: It is the “temple of light” which is one of eight Bahá’í temples worldwide.

It took many years to plan the temple. First, the building was modeled using the design software Rhinoceros. Then, the complete 3D model was transferred to RSTAB and RFEM and optimized in close cooperation with the architect.

Its form and materiality break new ground, drawing on the power of light as inspiration. Nine gracefully torqued wings of cast glass and translucent stone billow like sails, projecting a sublime, ethereal luminescence.

The building has a diameter of about 34 m and a height of 30 m. The building is structurally strong. Situated in a seismic zone, the structure’s innovative engineering accommodates ground movement while flexing under lateral loads.

Comprised of a steel superstructure, the Temple’s wings rest on concrete rings which sit on seismic isolation pads that separate them from the foundation.

This solution responds very effectively to the seismic, wind, and dead load effects and is compatible with the architectural requirements for translucency of the façade system with minimal shadow lines from the structural members.
