Castellana 81 is the first WELL office building in Spain and the fifth building in Europe to obtain the Gold WELL Building Standard in the Core & Shell category.
WELL is the first global certification for buildings focusing solely on human health and well-being and is based on seven years of scientific, medical and architectural research.
WELL certification is an innovative system founded by Delos and managed by the International WELL Building Institute™ (IWBI), set up in 2015. It certifies that the design, construction and operation model of the building addresses health and well-being of persons. It evaluates on site the building’s impacts regarding seven concepts: air, water, light, nourishment, fitness, comfort and mind.
