The LUCIA building, developed by the University of Valladolid, is an applied research facility designed to operate with net‑zero carbon emissions. The project combines bioclimatic design, reduced energy demand, and the exclusive use of renewable energy sources.

Performance assessments show that the building achieves net‑zero operational carbon, supported by on‑site renewable production equivalent to its energy use. It has obtained several certifications, including Passivhaus Platinum, LEED Platinum, and the VERDE 5 Leaves rating.

The LUCIA building illustrates how bioclimatic design, renewable energy integration and local resource use can support low‑carbon research facilities. It provides a replicable model for reducing energy demand and advancing net‑zero objectives in the building sector.

Key figures:

• Building condition: Constructed or refurbished in 2014
