New Sustainability

We work with the principle that sustainable building is not only a reasonable way to conserve energy, but the only way to shape our environment. For both the individual and the society, there are simply no alternatives to living with the benefits of and profiting from the earth’s natural resources intelligently - not only for the sake of our present, but also for the sake of our future. This is acknowledged by all civil organizations to one extent or another: communities and its denizens, industrial and economic sectors as well as businesses down to the individual energy consumer.

The sustainable approach is playing an increasingly greater role in design and execution, especially when taking into account the economic viability of individual properties or of entire city quarters. In the process, the urban space and its effect on the quality of urban life are of increasingly greater significance for the users.

In light of the impact that the association of effects such as the urban climate, transport infrastructure and the residential environment has on the society as a whole, sustainable design is invaluable in the successful marketing of real estate. Consequently, it is of great relevance for investors as well as the communities and their city quarters.

The DNGB certification system for sustainable building takes this issue into account under the user profile Neubau Stadtquartiere (German for new city quarters).

As a DGNB Auditor and DGBN Consultant, GTL Landscape Architects help guide private investors and public clients towards a DGNB Certificate. We are also involved in DGNB groups, for example for the Neubau Gewerbe- und Industriequartiere (German for new retail and industrial sectors).
