The transformation of cities into smarter and more sustainable environments is essential towards achieving the objectives of the decarbonization of the economy. In this sense, holistic strategies are required to design and implement urban regeneration strategies. The EU-funded REMOURBAN project has developed an Urban Regeneration Model which provides the mechanisms to implement more efficiently these processes, integrating technologies, business models, management procedures and evaluation mechanisms, where the evaluation is sought as the main supporting mechanism throughout the various phases of the city transformation process. The framework developed considers two levels of evaluation: city level, to assess both sustainability and smartness of the city as a whole from a comprehensive and integrated perspective, and project level, to provide a clear identification of the impact of implementation of technologies and solutions on three key priority areas (sustainable districts and built environment, sustainable urban mobility and integrated infrastructures and processes) aimed at achieving the city high-level goals. This paper introduces the Urban Regeneration Model and describes the evaluation framework and its implementation in the city of Valladolid (Spain).

This paper presents a novel evaluation framework to assess the effectiveness of city transformation projects related to energy efficiency and sustainable mobility actions. The evaluation framework is part of an Urban Regeneration Model designed to accelerate the urban transformation toward the smart city concept, taking into account all aspects of sustainability. This model has been developed and validated in the three EU cities (Valladolid, Spain; Nottingham, United Kingdom; and Tepebaşı, Turkey) where interventions in the energy, mobility, and ICT fields have been deployed. This model relies on an Evaluation Framework to support its main phases considering two levels of evaluation: city level, to assess globally the smartness and sustainability of the city, and project level, to support the decision-making and assess the impacts of specific implementations. This paper is focused on the second level and its application through the evaluation-supporting tool STILE in the assessment of the energy efficiency and sustainable urban mobility actions implemented in the city of Valladolid. The assessment analysis has allowed assessing how the energy efficiency interventions carried out in the Valladolid district have reduced the energy consumption, increased the use of renewable energies, and reduced the CO2 emissions. In addition, it has allowed evaluating other aspects such as the air quality, thermal comfort, and energy bill, which have been also improved for the residents. Considering the analysis of the sustainable mobility interventions, the evaluation framework supports the assessment of the reduction of emissions and air pollutants and how the actions have converted electro-mobility into a real option for citizens. The evaluation of results after the implementation of this kind of actions is key to ensuring that successful actions can be replicated in other places achieving smarter and more sustainable cities.

We performed an innovative STEM outreach project. High school students from the Colombian robotics’ designed a prototype of a Lunar Loo named Tech Lunar Toilet (TLT) that was part of the international HeroX-NASA Challenge. These experiences were possible thanks to a wonderful network of collaboration. As a result of this program, the students that participated were able to cultivate their curiosity, strengthen their scientific skills and increase their interest in pursuing careers in STEM fields. Simultaneously, they were able to contrast visual and instrumental data obtained from the robotics and new technologies that can be performed in the microgravity environments for future space explorations. The efficient TLT suction system will guarantee proper operation in both microgravity and lunar gravity. Most of the structure can be built in a 3D printer using PLA as a raw material. This polymer made from renewable resources with mechanical properties comparable to the petroleum-based ones will allow reducing the weight of the structure. We recognized that our project-based education is a powerful engine for development. We share our methodology for the construction of our TLT that can be used in microgravity. We also show the progression and impact of this innovative project of scientific dissemination.
