Trellis House achieved LEED Platinum certification by implementing the highest level of practical and measurable strategies and solutions aimed at achieving high performance in: sustainable site development, water savings, energy efficiency, materials selection and indoor environmental quality.

“Achieving LEED certification is more than implementing sustainable practices. It represents a commitment to making the world a better place and influencing others to do better,” said Mahesh Ramanujam, president and CEO, USGBC. "Given the extraordinary importance of climate protection and the central role of the building industry in that effort, RISE and Niles Bolton Associates demonstrate their leadership through their LEED Platinum certification of Trellis House.”
