The emblematic "ElCano" office building, located on Severo Ochoa street in Las Rozas (Madrid), has been the headquarters of ING bank in Spain for years. With an area of about 22,000 m2, it was designed by the architect Julio Cano Lasso in 1992. After its acquisition by Barings, its current owner decided to implement the BREEAM ES En Uso sustainability standard in the building. Likewise, and taking into account that a conditioning project for the building was to be undertaken, it was also decided to implement and certify the building with the WELL Core standard of health and wellbeing. Ineria Management is carrying out comprehensive consulting for both certifications, including preassessment, consultancy in the project and execution phase, WELL pretests, certification management with IWBI (International Well Building Institute), support in the implementation of improvements, audit and BREEAM certification report.
