Environmental certification of constructions and buildings is carried out by following one of the existing, internationally recognized, systems for assessing and evaluating sustainable development of infrastructure and construction. The benefits of such certification are numerous and are related, inter alia, to the building's own recognizable identity, to the property’s commercial value increase, to reducing its operating costs, to the improvement of indoor conditions and increasing the productivity of its employees and finally to the reduction  of its ecological and energy footprint.

OTEestate as a Gold Member of the USGBC (US Green Building Council) has certified its property at Kerameikos with LEED (Leadership in Energy and Environmental Design) at Gold level (Gold Certification). The building, with a total area of 10.850m2, is located in the historic centre of Athens and houses part of OTE Group Customer Service (Call Centre). The aim was to create a building modelled according to standards able to attain environmental sustainability, capable of providing an ideal environment for workers. Furthermore, OTEestate assets with LEED certification at gold level are: SOLONOS, COSMOTE TV_KIFISSIA.

New building projects have already been registered on the GBC (Green Business Certification Inc.) platform and their LEED certification process will soon be completed. 

Development and management services of various certification systems procedures are provided for OTE Group companies.

ISO 14001:2015

Environmental Management System  

A complete Environmental Management System has been developed and implemented according to the International Standard ISO 14001: 2004 at OTE and COSMOTE companies. Through the implementation of the Environmental Management System, OTE Group's top companies record, monitor, document, and ultimately limit the environmental impacts from the operation of their facilities and the use of materials, improving their environmental footprint.

ISO 14001: 2004 is an international standard, aimed at systematically managing the activities of a company with respect to the environment, in areas such as the use of natural resources, waste management and energy consumption.

ISO 50001:2018

Energy Management System  

The certification of OTE and COSMOTE companies with the Energy Management System according to ISO 50001: 2011 standard reflects their commitment to efficient energy management by continuously improving their energy performance through the adoption of best energy saving practices.

ISO 45001:2018

Occupational Health & Safety Management System

OTE and COSMOTE's consistent commitment that their Human Capital is their most valuable asset is also verified by their certification in OHSAS 18001: 2007 Occupational Health and Safety Management System. The acquisition of the OHSAS 18001: 2007 certificate is corresponding with the compliance of the above Companies with the laws, regulations and policies / procedures of the said System, which is implemented with a view to addressing the potential risks in order to protect Health and Safety of the employees and of the entire workforce thus reducing workplace hazards. 

Data Center sites’ certification services are provided on behalf of OTE Group with regard to the availability and functionality of their infrastructures.

Initially, facilities are designed to meet the highest and most stringent international operating and safety standards. The implementation study is then carried out with the construction details for all individual installations and then construction is implemented in a given timeframe, with emphasis on the operational tests of the installation, before the site is ready to meet the Group's IT needs.

OTE Group's Data Center design ensures certification Tier III Class by the Uptime Institute, which is one of the leading Data Center availability infrastructure certification bodies worldwide.

The Tier III (Concurrently Maintainable) certification of OTE Group's Data Centers confirms that the Data Center infrastructure is designed in such a way as to maximize the continuity of its operation against any damage to its core infrastructure (power supplies, air conditioning, etc.).

Given the prominence of the Uptime Institute in Data Center industry, obtaining this certification highlights the quality of OTE Group's infrastructure and exhibits  the philosophy that distinguishes it in terms  of its critical facilities security. 

Energy Management, conducive to its efficient use, nowadays constitutes a critical business activity in the pursuit of both sustainable development with respect to the environment and within corporate responsibility strategy.

For this purpose, OTE Group of companies have adopted, developed and implemented an Energy Management System (SDE), in accordance with the requirements of the international ISO 50001: 2011 standard.

OTEestate Energy Management section’s main objective is to tackle all relevant energy issues within OTE Group, some of which are the following :

• Energy Management System extension planning with regard to additional Group’s facilities based on its energy policy priorities.
