Data centers are specialized computer systems management environments . They cover reliably all the functional needs of such systems as electrical infrastructure, cooling systems, network infrastructure , continuous interface (uplink), physical security, fire security etc.

Previously, data centers were created to fill the needs of a particular companies or public services. The spread of computers and the Internet creates a constant need of unhindered access to computing power and storage space. This need reverses the relation of ownership - use existing and new data centers are usually generic computing infrastructures providing services via the Internet (cloud services).

It is estimated that in 2007 the sector of information technology and communications (Information and Communication Technologies ICT) was responsible for 2% of global carbon emissions, with the data centers to account for the 14% of the footprint of ICT.

Energy consumption is a key size for the data center. Decisions in the process of designing a data center such as size, position, shape of the building, equipment, etc., are taken in account primarily on the energy impact.

Aim of this thesis is to design a building to house a data center of large scale while covering a series of secondary support functions. The data center will house grid computing systems to create an integrated management system of virtual servers to sublease online. The design takes into account the needs of scalability, reliability and security of a data center tier 3 according to standard TIA-942. Particular attention is given to optimize its energy efficiency through the use of the special features of the site chosen.
