Energy-use reduction was a primary driver of the design. Simulations predict energy savings of 45% over a baseline code building. These savings are due to a combination of passive approaches such as daylighting, natural ventilation, and night-flush of thermal mass, and very efficient active systems. A large solar thermal array for domestic hot water and building-integrated wind turbines further add to the efficiency.

A 47% reduction in potable water use is predicted through use of efficient fixtures, low-water roof plantings, and rainwater reuse.
