solar - no solar belt area
A permanent installation in and around a rooftop guesthouse. The installation is built along the basic principles of passive solar energy. It changes and moves at unpredictable moments in temperature, depending on the solar radiation in the solar collectors on the walls. The guests can decide whether they want to use the coolness or the warmth from the collectors by opening and closing valves in the installation.
