There are a total of six AURAs dedicated to passively maintaining the building at a comfortable temperature range by using chimney effect along with earth tube system. Out of these six AURAs, the three lower ones intake cool air. Then the fresh air gets channeled through a series of earth tubes. The earth tubes act as a heat exchanger underground, which can capture heat from and/or dissipate heat to the ground before distributing fresh air back into the building at a more desirable temperature. The other three AURAs are located at the highest points of the building. The height difference between these and the intake AURAs creates a negative pressure which forces air to circulate through the building.

A set of three AURAs are wind energy generators which are constantly capturing the intense northwest wind all year long. The underground turbines which connect to the three energy generating AURAs are located towards the back of the lot to minimize vibration and sound pollution during the energy conversion process.

The topography of the "living roof" is optimized to funnel the wind toward the three energy generating AURAs. On the other hand, at the two lowest areas of the roof topography, two AURAs are built to collect and remediate rainwater and to recycle used grey water.

The remaining four hybrid AURAs have the built-in geothermal utilities working along side with the earth tube system. These AURAs connect to the radiant heating network that is embedded in the floor plates to warm the building at a minimized cost.

In the spirit of community and volunteer services that is very pertinent in the Presidio, people are welcome to take home charged batteries. Rather than requiring a paid membership, members can acquire them by donating their time to the various volunteer groups in the Presidio.
