New Timber Building of Health Sciences Faculty at UPNA, Spain

The building of the new Faculty of Health Sciences at the Public University of Navarra (UPNA) consists of four floors, each measuring 2,800 m² (30,139 ft²), constructed using cross-laminated timber (CLT) slabs made of spruce (Picea Abies) with a thickness of 180 mm (7 in) and the C24 strength class, supported by a truss structure of glued-laminated timber beams and columns, also made of spruce, with the GL24h and GL28c strength classes. The entire timber structure rests on a reinforced concrete structure that forms the ground floor and basement of the building.

The Faculty combines teaching, research, and healthcare, which brings significant benefits for students, teachers, healthcare staff, and patients. It is located on the grounds of the University Hospital of Navarra, next to the Faculty of Health Sciences building, where degrees in Medicine and Nursing and several postgraduate courses in the field of healthcare are taught.

The use of structural timber has been a key element in this positive-energy building, which will generate at least the same amount of energy on site as it consumes for heating, cooling, ventilation, and lighting.

Initially, a box system was proposed for the timber floor elements, but in the end, a solid CLT (cross-laminated timber) slab solution was chosen.

Design and Structural Analysis

The entire timber structure was calculated using RFEM 6 and the Timber Design and Multilayer Surfaces add-ons for the standard-compliant design. In addition to the required design checks, a local and global stability analysis was performed to ensure structural stability against buckling.

This project has been included as one of the 10 top mass timber projects in 2025 by the supplier of renewable products, Stora Enso.
