The Interventions

The elements that highlight the innovation of the project are:

  • The thermal insulation achieves significant energy savings resulting in a reduction in the consumption of available energy resources. At the same time, thermal insulation contributes to the protection of the environment by reducing emissions as a result of reducing of the use of fuels for heating buildings. It is estimated that the CO2 emissions for heating an insulated building are up to 45% lower than those of an uninsulated building.
  • LED technology is a relatively new technology in lighting with many advantages over traditional lighting technologies. The main advantage is that it offers very high Energy Efficiency. This means that about 80% of the electricity is converted into light, while about 20% is lost and converted into other forms of energy such as heat. The second main advantage is that they are 100% ecological and safe, unlike conventional fluorescent luminaires which contain a lot of materials, such as mercury, which are hazardous to the environment. In addition, LED luminaires are 100% recyclable, and all their materials can be easily reused. The energy savings combined with the wide range of options of LED luminaires makes them the first choice for lighting in offices and commercial spaces.
  • Heat pump technology is installed in any type of building, even in cases of buildings with radiator heating systems. With the heat pump we have a reduction in heating costs of up to 60% with at the same time a reduction in CO2 emissions by 50% compared to conventional oil heating. However, the same equipment can also produce cooling in summer provided that fan coils are installed. In this case we have heating in winter, cooling in summer and domestic hot water with a single system. The relatively high initial capital required for the installation can be recovered quite quickly due to the high efficiency of the unit, while the effort to use renewable energy sources and reduce emissions is enhanced.
  • Building photovoltaic technology is a system for generating renewable electricity to cover all of the building’s energy needs. The electricity produced can either be stored in batteries and used in the building in order to make it autonomous, or offered to the grid and used for net-metering. There is even the option of a hybrid system whereby the photovoltaic system supplies electricity to the building for self-consumption and, if there is a surplus, delivers it to the grid for a fixed amount. Building photovoltaic technology is one of the most reliable and efficient systems for generating electricity in countries with intense sunshine, providing the building with autonomy and great economy. Advantages include quiet operation, zero pollution, minimal maintenance, capacity to expand to the specific needs and independence from fuel supply for remote areas.
  • Building Energy Management System (BEMS) technology is a valuable tool for achieving optimum comfort conditions for users and operation for devices as well as for optimizing the energy consumption of the building. The use of sensors and automation results in real-time energy savings, and there is also the possibility of recording data. BEMS can also trigger alarms, in some cases predicting problems and informing maintenance schedules. It has the ability to keep records of historical performance, which allow benchmarking of performance and can help optimize building performance.


With the completion of the physical scope of the project, the five municipal buildings (1st Care Center for the Elderly, the buildings "MARIA-ELENA" and "SPYROS APOSTOLOU" and the school buildings 1st -3rd Vocational High School and 8th Primary School of Ag.Anargyroi) will have been upgraded to energy category B+ and above, with an overall primary energy saving of 86% and a reduction in CO2 emissions of 83%.
