2. E=mc2 (A. Einstein, 1905)
 1 g of mass is equivalent to 25GWh
 Energy is available for free
 Penalty (money) for improper use (conversion)
of energy
 E4Less (E = Energy / E = Efficiency)
 Efficient use of free Energy from Sun, Earth, Wind
 Energy Harvesting
 Energy for less money, with less carbons and less
harm to the earth and us

3. Introduction
 Data Center Energy Consumption is an important
part of Total Cost of Ownership (TCO)
 Most Green DC initiatives deal with servers’
power consumption and IT equipment efficiency
 E4Less challenges the operating expenditure by
applying existing and reliable RES technologies,
resulting in remarkable DC TCO reduction, PUE
improvement and significantly less CO2 emissions

Environment, the Society and our Customers
 Our Strategy:
 Use of Geothermal Energy and Free-cooling
technologies, locally available
 Efficient Passive Infrastructure, Data Center tailored
Design, minimizing Energy losses and allowing Energy
Harvesting

6. Data Centers – The Problem
 Data Centers spreading
 Increased need for additional processing power,
storage and networking
 High Density – Blade Servers
 Increased power requirements per rack
 Huge amounts of heat generation resulting in
huge amounts being paid for cooling

8. DC Cooling economics
 Each KW of power for Computing creates
1 KW (3412 BTU/h) of heat power
 1 KW of heat needs approx. 800W of
electrical power in order to be cooled (with
traditional cooling technologies)
 Hence, the yearly cooling cost for each KW
of servers is:
 0.8 KW × 1000 € / KW ≈ 800 € / KW yearly

9. Free Cooling – Geothermal
 Use FREE Energy from the environment
 Geothermal drills (steady earth temperature is
between 10 and 16 ˚C @3 meters below surface)
 Nearby Cool Water (river, pond, sea, etc)
 Atmosphere Cool Air (during winter or night)
 Exploit energy exchange from office
heating/cooling
 Solar & Wind Power options

10. DC Cooling with RES
 E4Less Solution benefits
 Cooling Costs reduction at least 50%
 Efficient use of RES can offer additional reduction (up to 80-
90% or more depending on location and climate conditions)
 Additional Savings from automatic real-time adjustment of
cooling power, depending on servers’ requirements
 Some Economics
 With a 50% reduction: 400 € / KW yearly
 Add savings from
○ Smaller UPS requirements
○ Less cooling energy consumption when IT equipment does not
operate at maximum capacity
○ Less CO2 emissions
