Heating and Ventilation in the Basilica of Arantzazu

Resumen:
The Basilica of Arantzazu is a recognized project, designed by the architects Luis Laorga and Francisco Javier Sáenz de Oíza, one of the most emblematic works of the church architecture of the twentieth-century in Spain. Although widely studied by architectural criticism, nothing is known about its interesting HVAC services, so this article analyzes and puts forward a technical aspect, heating and ventilation, providing critical examination of the abundant and unprecedented existing information about the original design of the main building services in this project. Results include unpublished information, redrawing from original plans and theoretical consideration about the role of the architects in the design and construction of these building services.
