A prerequisite for the energy upgrade of a property is the performance of an energy inspection that ranks it in the corresponding energy class (A+ to H). By producing appropriate intervention scenarios, the most desirable economic solution is selected for each user's data.

In times of economic poverty due to the economic crisis of recent years, such inspections have significantly helped a large part of the population to maintain their economic balance by implementing appropriate interventions.

In addition to financial support and improving the quality of life, the energy upgrade acts as an investment in the property, as it also leads to its economic upgrade. Property values increase significantly after such interventions and the properties themselves become more attractive on the market.

Zacharias Kotsimpos, registered after a successful examination process in the class B register of Energy Inspectors, has to date prepared more than 750 energy inspections and has prepared on behalf of his clients a significant number of energy upgrade studies through subsidized programs.
