Credits and Acknowledgments

The MIHOUSE team wants to thank the Faculties of Engineering, Economic Sciences and Social Communication at the Universidad Autónoma de Occidente (UAO) and Architecture at the Universidad de San Buenaventura (USB) that supported the development of the project:

 The Energetic and Mechanics Department at UAO, which provided the electrical, environmental, and waste and water management solutions.

 The Architecture Program at USB, which leaded the project, developed the design strategy and managed MIHOUSES´s research and building processes.

 The Faculty of Engineering at USB, which helped with industrial and agro industrial solutions and in the preparation of most of the multimedia content used in social networks, website, and public releases.

 The Communications Departments, which contributed to the team’s communications project.

 The Research & Technological Development Departments.

 The deans of the Faculties of Engineering and Architecture, Arts & Design for their constant support and encouragement.

 The heads of each of the study programs involved in the project who facilitated the participation of an interdisciplinary group of students and professors.

 The Language Center and Language Institute for their constant support with translations used in every delivery during the SDLAC2015 contest.

 The FabLab at UAO, which facilitated the construction of urban and architectural models.

 The Broadcasting Coordination at USB that helped with the preparation of all audiovisuals.

 Costume Design students who designed the uniforms of MIHOUSE decathletes.

 Arch. Liliana Carvajal for helping with the financial aspects of the project and for her unconditional support.

 Professors José Salazar and Jerfenzon Vidarte for their advice on the project´s economic feasibility.

 Professor Luis Alberto Buitrago for his advice on urban orchards and home gardens.

 Arch. Lucas Arango and his team; Eng. Carlos Castang and his group of students; and Arch. Carlos Giraldo for their contributions with the bioclimatic aspects and calculations.

 Teacher Carlos Ortega for his support with translations.

 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.

Introduction

Globally, the concern for climate change has led governments and the community in general to consider the affectations that we as humans have been doing to the planet. The production of electricity is a relevant factor due to the pollution produced by fossil fuels used for this purpose. The excessive industrial production to cover the growing demands of products and services, combined with the disproportionate use of transport systems that use internal combustion engines responsible for the thousands of tons of CO
