IKOSIA: energy efficient, sustainable & simple Underline

At IKOSIA we believe in the transformative power of sustainable and individual solutions for real estate and residential buildings - and in the fact that environmental protection and energy saving measures should not fail because of bureaucratic hurdles.

IKOSIA: energy efficient, sustainable & simple

Our history

For us, climate-friendly living and living begins before the renovation: By carefully preparing your renovation project - from individual energy saving measures to holistic renovation concepts - you can secure maximum government funding. This not only reduces the burden on the environment, but also on your wallet. 

To do this, we combine cutting-edge technology with environmentally friendly practices. Using your building data, we determine your realistic savings potential and identify suitable renovation measures.


What sets us apart & how you benefit from it

At the heart of our green renovation initiatives is our dedicated and passionate team, a diverse mix of people driven by a shared mission: to make real estate more sustainable to contribute to climate protection.

Each member of our family brings their own perspectives, skills and enthusiasm for our mission and your renovation project. The result: Every project becomes a masterpiece of sustainability. Maybe soon yours too?
