Clean Tech Testbed

"Under the Håll Ut set up, a first testbed platform for conducting rigorous, transparent, and replicable testing computational products and new technologies was developed. By the Håll Ut testbed, new experimental concepts on certain environments are tested. From a pool of potential environmental friendly solutions there is a selection of a dropdown list where each solution is scanned and tested. Based on the solution selected, a specific sustainability (e.g environmental or energy goal) in a municipal level is selected accordingly. In order to have measurable results to each tested solution, specific case data are provided as input.

We at HållUt strive to have a honest and open interaction with all our partners, members and costumers building the foundation of prosperous and fruitful relationships.

Specialized knowledge, experience and cooperative partnerships deliver great value. Reliability, objectivity, and good good knowledge are our most valued assets.


We dare to take different viewpoints in order to find new solutions for our partners. This is the defining component of our innovative thinking. Moreover due to our very close connection to Uppsala University and the Center of Sustainable Development (CEMUS) we can enhance new ideas from scratch to breakthrough projects. Open discussions with direct feedback can create an environment that allows new ideas to thrive. High ambitions and empathy stimulate this innovativeness and creativity.
