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 lessharm to the earth and us
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
E4Less – Who are we?
Engineering team with more than 30 years
combined industrial experience in:
Telecommunications and IT Solutions
Data Center Passive Infrastructure Design and
Implementations
RES and Geothermal installations
Smart Homes / Smart Buildings
Startup – Founded in 2010
E4Less – Mission and Vision
Our Mission: To promote the effective use of Renewable Energy Sources
in Green Data Centers, in order to Protect the Environment and minimize the Total Cost of Ownership
Our Vision: Truly Green Energy Data Centers that benefit the
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
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

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
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
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
