Green Building

Green Building

Sustainable building with vision

A responsible attitude towards nature, climate-friendly energy technology, economical use of resources and access to clean drinking water are criteria that will decide our future. This applies in particular to buildings, especially with regard to their profitability. Given that they have an operating life of 40 to 80 years, property owners and principals are faced with key questions.

What is still marketable today?

The general public, policymakers and industry face great challenges in view of climate change and the continually increasing global demand for natural resources. The combination of ecological and economic sustainability is the order of the day for the real estate industry. Nonetheless, there are many questions on the path to sustainable buildings.


What is the best way to coordinate the complex interactions between individual trades, such as between the building envelope and building services equipment?
How do you plan and implement economically feasible reconstruction and regeneration measures against the background of international certification standards for Green Buildings?
How can one ensure that the building delivers on what the planning promises, thus guaranteeing sustainability in operation?
What tools can be used to ensure that the finished Green Building was built in such a way that the targeted eco rating is achieved?
