The cooling from evaporation of water just like the natural perspiration process in our bodies, is transferred to the air stream that enters our building, cooling our data center, servers and office. Hot, moist air is rejected to our solar panels for cooling and the moisture in the air is dried and renewed through rain for use again and again.

Just like getting out of a pool in the summer time, a small wind will be enough across your wet skin to create cooling, this process is known as evaporative cooling. Our air conditioning systems use mother nature for cooling in a similar fashion, water is evaporated into air in one chamber and this cools the air flowing in an adjacent chamber. The cold air is used for cooling while the water vapor holding the heat is exhausted outside to be renewed by the atmosphere.

Our air conditioning system:

• eliminates the need for refrigerants by using rainwater collected off our buildings, which is then used to cool outside air. This cold outside air is then pushed into our data center and office. These methods use 90% less electricity (600 watts max), create an EER of 40+, use water instead of electricity for cooling, and have zero water impact.

Saves emissions in 1 year*:

• over 72,504 pounds of CO2 (Greenhouse)
• over 106.2 pounds of Nitrogen oxide (Smog)
• over 78.8 pounds of Sulfate (Acid rain)

Our air conditioning systems and green roof need water, we looked to mother nature to provide what it already gives us for free, rainwater. Using our rainwater collection system on our roof, the rainwater collected is used for our air conditioning systems for cooling and to water our green roof during dry periods.

The long history of rainwater collection, can be traced as far back as ancient times some 3,000 years ago (850 BC) if not even farther. Using our rainwater collection system, the rainwater collected is used for our air conditioning systems for cooling and to water our green roof. The excess water from watering our green roof is recouped by our rainwater collection system.

Our rainwater collection system:

• eliminates the need for city water by using rainwater collected off our building. This allows 100% of our water usage to come from mother nature.

Water collection specs:

• first flush system to remove water contaminants during first rain
• storage for over 10,000 gallons of water
• air conditioning system drain water is reclaimed for reuse
   

Green roof history stems from ancient times such as the Hanging Gardens of Babylon, built by King Nebuchadnezzar II in about 600 B.C., were mountain-like series of planted terraces. More recent engineering of green roofs are the early European settlers in the Great Plains of North America built "soddies," or sod-covered homes, during the period of westward expansion. Taking these ideas we are in the process of building a green roof to cool our data center and office to reduce temperatures by 20 degrees or more.
