Green IT

The Green Information Technology (Green IT) is a way to save energy and make better use of all information technology services, such as data centers, software services, communications, and their power supply.

Data Center:

Each year, organizations spend a lot of money on purchasing a server for their organizations, while can be reduced by up to 75% using virtualization technology.

The basis of this technology is based on the use of a server device and the installation of several operating systems that work in parallel. In this way, there are many software solutions that Microsoft and VMware companies are among the pioneers of this technology and offer a variety of software in this regard. One of these solutions is the reduction in the power of the servers based on their needs. On each server, you need to be careful about how much server performance, equipment is projected and designed to fit the power supply. When the server is not used, such as nights and holidays, we minimize the amount of power it consumes. By doing this, the power consumption will decrease up to 50% per year. The cooling systems in data centers are also one of the most energy-consuming appliances. Proper design of the cooling system can, in addition to being more effective, reduce the energy consumption up to 25%.

Personal Computers:

Personal computers in offices are one of the most used equipment, which consumes about 40% of electricity in organizations and offices. By implementing some software changes in their use, they can significantly reduce power consumption. For example, in many cases when users are not behind their computers, the computer is active and useless, which uses Hibernate software to detect system idleness and restarts if needed. The use of low-power components for systems is one of the other ways in which the service terminal solutions can be mentioned. The use of low-power components for systems is one of the other ways in which the service terminal solutions can be mentioned. This service is powered by equipment called Thin Client and MiniPC, which reduces at least 70 percent of the power consumption by this method.

Active network equipment:

These equipment are used more in the network infrastructure; it has been observed that in many organizations there is a surplus of equipment purchased on the basis of the service’s demand, which also results in higher costs due to the fact that more energy-consuming equipment consumes more energy.

And as a result, more funding has been paid for equipment. In the same vein, manufacturers of the company, active equipment of the network have also produced low-power models of this device, which can be used at a lower cost, to provide these devices and to reduce the cost of energy consumed.

Inactive equipment of the network:

The implementation of inactive network infrastructure in any organization is one of the most costly IT-related executive initiatives that normally require reconstruction and renovation every few years.

There are a number of ways to reduce costs and reduce the cost of maintaining this platform:

  • Use of modular equipment
  • Use of Trunking and Continuous Systems
  • Use of blind replaceable optical fiber substrates

Paper and Printers:

Printers are one of the most important and most used devices in organizations, which spend a lot of money on their toner every year. Unfortunately, due to the incorrect thinking of some experts that using a charged toner causes a printer to fail, all toners are bought as new. While according to a report by major manufacturers of printers and consumables such as HP, Canon, Using a factory-recharged toner can reduce up to 60 percent of the cost of toner purchases. Given the expansion and growth of information technology, the need for software automation systems in organizations is felt more and more. The approach of these automation is to incorporate the volume of internal and external communications into e-mail systems and reduce paper consumption up to 80%.


Electronic components, batteries, toners, and hardware equipment used in the IT field are known to be one of the most hazardous waste after nuclear waste after their life has ended, and if they are released in the environment, they will be irreparable damage. It is expected that the green information technology will be provided to the environment where after the end of the life of the IT equipment, the manufacturer of the equipment will return it to the cycle and safe disposal method.

Green information technology is a four-dimensional approach:

  • Green approach in the green technology service provider can be found in the green office guide.
  • The green approach in energy efficiency and energy saving and the optimal use of all services Information technology (such as data centers-and …)
  • The extent of software impact in the green approach
  • Waste management in information technology

First dimension: IT service provider

The green approach in information technology is tracked by focusing on processes and delivery methods in the “IT service provider”. In this section, the areas of water, energy, paper, transportation, waste, air and noise, purchasing and procurement of the provider through the Green Office Guide are evaluated. The weight of this amount is estimated at 33% of the total score.

Second dimension: IT equipment and technology

The productivity of the equipment used in the process of providing services is focused. The amount of energy consumed, the lifetime of the equipment, the environmental conditions, and the mechanism for caring and controlling of the equipment, the knowledge and skills of human resources and its management systems are audited. The weight of this amount is estimated at 23% of the total score.

Third dimension: Software used

The impact of the software used to optimize the resources is focused. The fields of paper, time, energy, fuel, and the volume of environmental pollution reduction are being audited. The weight of this amount is estimated at 25% of the total score.

Fourth dimension: The Waste of Information Services

Environmental implications the equipment used to provide IT information services in their life cycle is identified and reduced. In the life cycle of equipment, their end-of-life period is the key question. What is the strategic, operational, and executive action plan for the waste left over by the organization? The weight of this amount is estimated at 25% of the total score.

The green IT model has 310 indicators in the domains mentioned above. These indicators can be used in the form of user-defined checklists and allows the user to audit and rate the IT company in terms of the conditions of a green IT.

The method of scoring in this model determines the distance to the ideal level and the user can define the improvement projects accordingly.

In this model, prioritizing improvement projects is one of the important issues that are determined by a scientific method through scoring cards.

Auditing and Certification:

This model, after implementation of improvement projects and internal audits by users, based on company requests, External audits are conducted by the experts of Sustain Ever and ultimately lead to a formal certification by The Energy Globe Foundation.

Certificate of the Energy Globe Foundation is one of the most known in the world. The Energy Global Foundation has 182 member countries.

Note: An external audit of IT company can be made in an unobstructed and self-explanatory manner by the applicant.
