Thornton Tomasetti analyzed and developed several sustainable strategies which were incorporated into the design of the building. Greywater reuse and rainwater harvesting systems were combined with detailed daylighting studies to reduce solar gains in the summer. The team used Honeybee software to evaluate the effects of automated interior blinds and calculate the efficiency of exterior shading devices. Other sustainable features include multiple green roofs, accommodation for low-emitting vehicles and native landscaping.
