Energy efficiency and renewable energy are said to be the twin pillars of sustainable energy policy and are high priorities in the sustainable energy hierarchy. In order to ensure a future proof sustainability of the society we have developed two major segments of energy solutions: energy audits and smart grids.


— Energy audits – we set the base for energy and cost optimization of your facility. With a total area of more than 1 million m2 inspected and more than 500 energy audits issued, we are Croatian leader in the energy certification.

You can see the list of our Energy audit and Energy certification projects here.


— smart Grid‑Following global trends we participate in development of intelligent networks, based on advanced information and telecommunication technologies that allow the integration and connectivity of producers and consumers of all sizes as well as different technologies and energy sources.
