To bring glare-free and uniform levels of daylight into the airport, the terminal is topped by a lightweight and modular roof design made from twin-wall polycarbonate with nanogel infill sandwiched between two PTFE layers. In addition to minimizing dependence on artificial light by 90%, the roof structure also provides superior levels of thermal transmittance, solar control performance, and acoustic separation. If constructed, the inner PTFE membrane would have also been treated with a low-E coating to minimize ultraviolet rays and further reduce heat transfer.

The terminal design is outfitted with a passive, renewable energy system comprising earth tube pre-conditioning to halve heating and cooling burdens as well as a radiant floor system to decouple the heating and cooling from the fresh air systems. A natural wetland design feature collects and filters rainwater to ensure that none of the onsite rainwater enters the municipal sewer system. The architects calculate that the addition of a 700,000-square-foot PV system would be sufficient to push the design to net carbon zero levels.
