What it's like to work in an office building that was designed based on the Passive Building principles and why this German company chose to build it that way.

I talked to Volker Brock, CEO of Hanno and Philipp Staude, R&D of Hanno to understand on what encouraged the company to go the extra mile to provide a healthy, comfortable and energy efficient office building for their employees and I received first hand experience feedback on what it's like to work in such a building.
