What is
greenventory?

greenventory is a high-tech startup from Freiburg, which has made it its mission to bring the energy transition in the cities.

For this purpose, we offer our customers the necessary decision-making and data basis to enable forward-looking planning of energy systems.

17-layers

Software for Energy Transition

greenventory offers a software based solution for mapping and analysis of custom energy systems. For this purpose, a large number of data sources are brought together, evaluated and used to build a building-ready data base for the energy system. Based on this, options for action can be evaluated transparently and future development paths can be explored.

19-layers

Scientists and Engineers

Based on this, options for action can be evaluated transparently and future development paths can be explored. We are a dedicated team of scientists and engineers with fun with data and the simulation and optimization of energy systems.

14-layers

Forward Looking

Our understanding of both humans and the environment creates the foundation for future-oriented and customer-oriented results.

We empower people of action with the data and tools they need to design the transition towards sustainable energy.

Freiburg from the sky

With the software solution developed by Greenventory, utilities, network operators and cities can individually map, analyze and improve their energy system.
