The energy certificate is issued by a special body of energy inspectors, it is valid for 10 years and the cost is charged to the owner. In the case of blocks of flats and generally properties with a shared central heating system, the law allows the issuance of a common energy efficiency certificate to be issued for the entire building, the cost of which should be paid by all co-owners according to their ownership of the entire building. The energy inspection for the construction of heating and air conditioning at regular intervals is mandatory by law.
Class B energy inspectors of «Kotsakostoudis Group» company, who are certified by the Ministry of Energy, undertake the energy inspection and certification of buildings, boilers & heating and air-conditioning installations. The company also undertakes the preparation of energy efficiency studies KENAK (Regulation of energy performance of buildings) for new buildings, which now replaces the old thermal insulation study. All calculations are carried out with the help of a special certified software.
Our company, having knowledge and experience in the field of energy, undertakes:
- Studies of buildings on how to save energy in lighting, air conditioning and heating
- Bioclimatic Design Studies
- Active solar systems & Geothermal studies

The consumption of natural gas in domestic, professional and industrial use, offers countless benefits to the user, while contributing to a cleaner environment and upgrading the life quality of citizens.
In order to connect any facility to the public gas network, a special natural gas engineering study must be prepared and submitted to be approved by the competent company that manages the natural gas network.
The «Kotsakostoudis Group» company in the field of natural gas has been active since 2007 with the aim of correct studies for fuel gas and thermohydraulics installers with the ultimate goal of safe installations for the company’s customers with continuous supervision and maintenance of these installations.
Renewable energy sources (wind energy, solar energy, hydropower, ocean energy, geothermal energy, biomass and biofuels) are alternatives to fossil fuels and contribute to reducing greenhouse gas emissions, diversifying the energy supply and reducing dependence on buying unreliable and volatile fossil fuel markets; EU legislation, for the promotion of renewable energy sources, has evolved significantly in recent years, and for this reason large and small-scale constructions, which contribute to the ever-increasing percentage of consumption of energy coming from renewable sources, are financed from time to time.
Photovoltaics
The user’s energy independence is the biggest advantage of Photovoltaic Systems. The cost of electricity produced by Photovoltaic Systems is currently comparable to the cost of peak power, which the electricity company charges its customers. The categories of Photovoltaic Systems are:
- Large Grid-Interconnected Systems (50 kW – 5 MW) (e.g., parks)
- Interconnected Systems – Residential Sector (1.5 kWp – 20kW) (e.g., on roofs or facades of houses)
- Autonomous or isolated systems (100 W –200 kW) (e.g., off-grid homes and small settlements, rural applications)
- Consumer products (1 mW–100 W) (e.g., caravans, pleasure boats, outdoor garden lighting, refrigeration)
The Kotsakostoudis K. Vassilios & partners ADVISOR ENGINEERS company completely undertakes the installation study for the Photovoltaic Systems (parks or roofs) as well as the support in all phases of a project, from the selection of the field, where the park will be built, the feasibility study and licencing to the correct location of the installation.
Geothermal energy
The installation of a geothermal system for heating in both new and existing buildings is a top choice, which ensures the lowest running costs compared to all other heating systems using conventional fuels (petroleum, natural gas, liquid gas, air-cooled heat pump, etc.).
For the application of geothermal systems in heating systems, in order to be reliable and energy efficient, it is necessary to prepare a Heating Study in combination with a special engineering Geothermal Study which requires specialised knowledge and experience as well, since Geothermal Systems are extremely complex engineering applications.
The Kotsakostoudis K. Vassilios & partners ADVISOR ENGINEERS company completely undertakes the Geothermal heating and cooling study as well as the Geothermal Installation Study which is required to be submitted to the competent Directorate of Development of the Region for the issuance of an installation permit for all types and sizes of buildings, having a fully organised and excellent qualified Department of Consulting Engineers in energy matters.
Biogas Units
Biogas Production Units, which base their operation on recycling nutrients and organic substances, in an environmentally friendly way, are an alternative method to the issue of sustainable management of the ever-increasing livestock and organic waste. Waste from slaughterhouses, manure, herb and cheese food processing factories can be used as an energy source in biogas production units.
The Kotsakostoudis K. Vassilios & partners ADVISOR ENGINEERS company completely undertakes the design and study for the installation of a small or large-scale biogas utilising the organic waste of your facility and turning it into sustainable green energy.
