The Maestría en Bioclimática at Universidad de San Buenaventura Medellín.

The MIHOUSE team also recognizes the enormous support from its sponsoring companies and hopes that the established relations can continue being fruitful over the next years and in future projects:

It is also important to thank USB and UAO for their valuable efforts that made possible the disassembly of the MIHOUSE prototype constructed at the Solar Villa and its reassembly at USB campus, where it is being turn into a Sustainable Housing Laboratory. In the next years, the MIHOUSE Laboratory will serve as a place for research and experimentation with solar panels, furniture and other innovative technologies related to energy efficiency, indoor air quality, humidity, water management and sustainability. Undoubtedly, this laboratory will be a milestone that will allow the training of architecture and engineering students in future Solar Decathlons.

Last but not least, the MIHOUSE team wants to thank the Solar Decathlon organizers for making possible this event, and the people of Cali that kindly selected our housing prototype as the second favorite house in the Solar Villa.
