Whether it’s an energy certificate, heating load calculation, or funding — as energy consultants we’re here to help you competently!
Together with our clients, we define goals whose implementation isn’t always possible “by the book,” and we develop strategies to achieve them.
We generally rely on preventive preservation of building structure and fabric, using modern and innovative drone technology for diagnostic purposes.
