As one of many design firms that have worked at this historic site over the years, we are thrilled to share that the Navy Yard Philadelphia has just been certified by the U.S. Green Building Council as the largest LEED Gold neighborhood in the nation. Congratulations to Ensemble / Mosaic on this incredible achievement!
This Earth Day, we’re excited to announce a monumental achievement. Ensemble Investments, LLC and Mosaic Development Partners JV are proud to share that the Navy Yard Philadelphia has officially become the LARGEST LEED Neighborhood Development in the United States, earning the prestigious LEED-ND Gold Certification. The certification effort, led by Ensemble and Mosaic (Ensemble / Mosaic), encompasses more than two decades of vision and collaboration to transform the Navy Yard into a model for sustainable urban development—bringing together community, green infrastructure, and innovation across 295 acres and 77 buildings. So why does this matter? LEED-ND certification isn’t just about buildings—it’s about creating a healthier, smarter, more connected way to live. The Navy Yard’s scale allows for real environmental impact—reducing energy use, improving air and water quality, and cutting carbon emissions. But it also makes life better: walkable streets, abundant green space, thoughtfully designed infrastructure, and a dynamic mix of places to live, work, and play. It’s a neighborhood built not just for today—but for decades to come. This milestone is just the beginning of the Navy Yard’s transformation into a vibrant, sustainable community. Ensemble and Mosaic are poised to continue this momentum with an ambitious 20-year plan to bring 8 million square feet of LEED-certified residential, R&D, office, retail, and hospitality space to life.
