In collaborating with developers, architects and specialist engineers, KPPK Ziviltechniker GmbH have been helping shape the process of planning and construction since 2005, and in doing so have created visions and thus efficient solutions for active climate protection.

The goal of sustainability is to raise environmental awareness in the construction process and to find a balance between the use and regeneration of resources. This entails an interdisciplinary cooperation in each project between disciplines such as structural engineering, building physics, fire protection, and building services engineering.

With customised energy and climate concepts, we can respond individually to a wide range of usage requirements and local conditions.

In particular, the ecological and economic use of renewable energy such as solar energy and air or geothermal energy is a key issue.

Our customers are integrated in the building process from the very beginning as partners – because only then can good construcitons come to life.
