**5. Conclusions**

The main contribution of this work is to present the overall framework of Distrito Tec's Campus City project that includes an open innovation ecosystem and the Challenge Living Lab as a platform for the identification of high-socially meaningful projects that could be used as a pedagogic opportunity for the development of competencies needed to solve different community-industrial-governmental Pain Points.

It is concluded that Distrito Tec's Campus City is an ambitious initiative that aims to provide the industry, government, academia and especially the community with innovative and smart solutions to the current high impact and complex Water, Energy and Mobility problems. The Campus City open innovation ecosystem allows the identification of these highly relevant challenges that could be solved through the use or design of disruptive technology. By solving these challenges, the wellness of the community and the efficient use of resources could be achieved.

Consequently, the Challenge Living Lab is highly relevant as the selected challenge provides the ideal pedagogic framework for the students to develop different competencies and skills that they will require throughout their professional life while fostering the identification and solution of highly relevant problems for the community, industry, governmen<sup>t</sup> and academia.

Moreover, Challenge Living Lab platform opens the possibility for international and multidisciplinary projects and collaboration with different research institutions and governments. For instance, different challenges from the Challenge Living Lab, Smart Mobility vertical were tested in a pilot program as a "4.0 Energy Harvest Challenge" with the Indian Institute of Technology, Kharagpur. Students engage in a design challenge for different interconnected technologies for energy harvesting. More research is needed to scale-up this program to other institutions and include different common problems for the institutions/communities involved, which could generate logistical problems among faculty and students.

The scope of this work is defined within the Distrito Tec transformation initiative, in which the Tecnologico de Monterrey university, the surrounding Community, the Municipal Authorities and Private Companies are committed to generate an urban transformation that inspires other districts and cities to undertake continuous transformation to improve their Quality of Life. However, the Distrito Tec projects and their implementation depend on the willingness, commitments and agreements between the community and the municipal authorities. This represents a challenge, because the Distrito Tec project has a horizon of 15 years during which the renewal of municipal authorities will take place several times, disrupting the continuity of the project. Therefore, the active involvement of the academia through Campus City projects could play an important role as a catalyst that constantly provides solutions, technology, and human resources to keep track of those agreements and aid in the continuity of the Distrito Tec project despite governmen<sup>t</sup> transitions.

Future work should address: (1) the scaling up of the proposed framework into a model that could integrate different sectors, stakeholders, and communities, (2) followup and implementation, on a city-level or industrial scale, of the proposed challenges' solutions based on interconnected technology and (3) the evolution of the socio-cultural impact and Quality of Life by the implementation of the Campus City project (triple bottom line, people-planet-profit).
