PROSOCO helps world’s busiest land port achieve extreme energy efficiency
Each day, the equivalent population of a good-sized U.S. city (an estimated 102,000 people) travels through the San Ysidro Land Port of Entry, the busiest land port in the world that processes pedestrians and vehicles passing the border between San Diego and Tijuana, Mexico.
Besides handling that immense volume of traffic, the facility also houses offices and operational space for employees who work at the port of entry.
In a joint project between the U.S. and Mexican governments, the entire facility is in the midst of a $625 million overhaul involving the expansion of vehicle lanes and inspection booths, the demolition of the old administrative building and new construction of a multi-story replacement, and more.
The new administrative building is about 200,000 square feet with three above-grade levels and one below-grade level.
The owner of the project, General Services Administration, called for a lofty ambition for this structure – net-zero energy, meaning the structure will supply as much power as it uses. Once completed, the port will be the first facility open 24 hours a day, seven days a week and 365 days a year to achieve this goal in the U.S.
The waterproofing portion of this massive project called for a high-performance air barrier, said Peter Spruance, AIA, architect at the Miller Hull Partnership, which designed the port-of-entry renovation.
That bid went to PROSOCO’s R-GUARD air and water-resistive barrier products, which are lab-tested to meet some of the industry’s most stringent environmental standards and metrics for energy performance. These products were used on another recent net-zero-energy, high-performance project – the Bullitt Center in Seattle. Continue Reading »
