Three data centers in separate time zones give Green House Data reach across North America and even into Europe, offering clients colocation services and disaster recovery, along with hosting options in public, private and hybrid cloud. Throughout its recent expansion of facilities to Portland, Ore. in March 2012 and Newark, N.J. last December, the Cheyenne, Wyo.-based provider has maintained a focus on sustainability. The company is an Environmental Protection Agency Green Power Partner, running its facilities on locally sourced, renewable solar and wind energy, and purchasing renewable energy credits to offset additional wind energy requirements. Location was a key factor in achieving this efficiency: The Cheyenne center is positioned in a cool climate in the midst of a Class VII wind zone, the category with the strongest winds at the highest average speeds, making free cooling and wind power practical options. Taking advantage of Portland's rainfall and chill temperatures with an Indirect Evaporative Cooling system lets Green House skip the compressors for a low PUE. Using solar panels, harvesting rain and repurposing cooling tower blow-down water for irrigation distinguish the LEED Gold-certified Newark site from its local counterparts.
