The 31 Tannery Project is a sustainable office building in Branchburg, New Jersey, designed to generate all its own power through solar technology integrated into the roof and structure. The building operates with advanced heating and cooling systems that distribute energy efficiently across multiple zones throughout the workspace.
The building opened in 2006 and became the first commercial structure in the United States to operate completely independently from the electrical grid. This achievement established a new model for how businesses could manage their own energy production and consumption.
This building functions as an educational center where professionals study advanced energy monitoring systems and sustainable construction methods in commercial architecture.
Visitors can tour the building to see the energy systems in action, but access is typically limited to scheduled visits arranged in advance. It is best to contact the facility beforehand to arrange a visit at a convenient time.
