How to develop your existing buildings future-oriented


Ecological footprint, CO2 balance, climate targets … – the pressure on the real estate sector is increasing. However, true sustainability is not characterized by being awarded a certificate for a single lighthouse project. Rather, the building stock in its entirety must become more sustainable.



Holistic: the economical component of sustainability

As one of the 16 initiators of the DGNB, CalCon dealt early with the question how this can be implemented in an economically sensible way. Not only is it necessary to know the energetic state of each building. It is also important to qualify the portfolio according to ESG criteria. On this basis, the different measures for energetic refurbishment and modernization are then purposefully prioritized.

In this way you make your entire building stock fit for the future – without losing sight of the economy.
