Puerto de Somport 21-23 is a 20,000m² building designed to deliver on Tishman Speyer’s ambitious sustainability goals. To incorporate sustainability holistically, Tishman Speyer set objectives based on LEED and WELL standards and conducted a life cycle assessment (LCA) as part of the building design process.
As a result, a 2,700 tons CO2 reduction has been achieved, and the building is on track to achieve LEED BD+D v4 Platinum and WELL v2 Gold and Global Safe Site certifications.
Puerto de Somport 21-23 focuses on the efficient use of natural resources. The building is projected to reduce indoor water use by more than 50%, and energy by 26% versus comparable baseline buildings. Additionally, the aluminum façade and structural steel have a 78% and 88% recycled content percentage, respectively.
