With a 40% reduction in energy consumption, Eurobank brings to the forefront a tangible resultfrom the interventions being implemented at the Nea Ionia Campus.
This development reflects the Bank’s shift to a more efficient energy model, where energy management is directly linked to the operation of critical infrastructure and overall operational performance.
In this environment, the Eurobank Campus in Nea Ionia, as noted, is one of the Group’s key operational hubs, bringing together critical IT, digital banking and central services activities. In this environment, energy management is not just an environmental practice, but part of the Bank’s broader business transformation, with measurable results in consumption, cost and operational efficiency.
The Campus and its infrastructure
According to the Bank’s data, in a functionally integrated complex that spans individual buildings with a total surface area of 34.000 square meters, employs approximately 2,500 employees, while it hosts, among other things, conference facilities, a training center, restaurants, a medical clinic and two ATMs for the convenience of employees, as well as supporting infrastructure with a high level of accessibility. The complex has organized parking spaces, while it also incorporates practices that enhance sustainable mobility, such as bicycle spaces, electric vehicle charging points and a special route that connects the Campus with the Nea Ionia electric train station, facilitating the use of public transport.
The core of the complex was built in 1927 to house the textile factory “Mutalasky”, which was founded by refugees from Asia Minor and later joined Piraeus-Patraiki. For decades it was a main pillar of industrial activity in the area, before being redeveloped in 2001 for the needs of the Organising Committee of the 2004 Olympic Games. Since 2006 it has been owned and used by Eurobank.
Energy upgrading of infrastructure
In recent years, the energy dimension of the Campus has been a key area of intervention. According to the bank’s most recent data, the complex has been certified to the international LEED standard, and according to the Energy Performance Certificates it has moved from category C in 2013 to the higher category A+ in 2024. More than 1,200 photovoltaic panels have been installed on the buildings’ roofs, with an annual production of about 1 GWh, covering about 13% of the Campus’ energy needs. At the same time, in storage infrastructure in Acharnes, similar installations cover 100% of their energy needs, enhancing the use of renewable energy sources.
Special emphasis has been placed on managing consumption in critical infrastructure, such as the Data Center, where an increased energy burden had been identified due to support operations. Through targeted interventions, the energy efficiency index (PUE) has been significantly improved and the Data Center’s annual energy consumption has been reduced by approximately 800 MWh, with a corresponding reduction in operating costs.
In an environment where critical infrastructure operates continuously, energy efficiency is directly linked to ensuring reliability and quality of service. In the case of the Eurobank Campus, the interventions are not only linked to environmental objectives, but also to ensuring the smooth operation of systems and optimising infrastructure performance.
Measurable results in consumption
The results of the interventions are also reflected quantitatively.In terms of total consumption, the annual energy consumption of the Campus has decreased from about 12.4 GWh in 2017 to 7.55 GWh in 2025, recording an overall reduction of 40%,which corresponds indicatively to the consumption of a small town with about 2,500 inhabitants, while in the last three years alone the reduction amounts to about 20%.
The interventions that led to these results were multi-layered and included upgrades to lighting with LED technology,
optimization of air conditioning systems and modernization of the Building Management System (BMS). Also, interventions in the building envelope, such as thermal insulation and glass replacement
These interventions have addressed long-standing challenges, contributing to both reduced energy consumption and improved thermal comfort, with significant benefits in individual building facilities, where energy savings can be as high as 50%. At the same time, the operation of the Campus is supported by real-time monitoring systems, which allow for the continuous recording of energy production and use and the continuous evaluation of infrastructure performance.
In this context, energy is treated as a strategic tool, integrated into the overall operational and development planning of the organisation.
The case of the Eurobank Campus highlights how energy management can be integrated into the overall operation of a large organisation, functioning not only as a tool
