CONTEXTThe reduction of de CO2 emissions and the use of renewable energy resources are today the main challenges for authorities in the developed countries. The lack of serious awareness and the limited knowledge about it in our society makes that the users of our buildings (who consume approximately 90% of the energy) do not participate actively in achieving this goal, essential to avoid serious problems on the planet.Until a few years ago, the saving of energy and resources during the life cycle of the products were barely studied and most of the initiatives on estimation of the carbon footprint were focused on the energy efficiency factor during the useful life, but not in other important factors, such as the emissions of CO2, the consumption of resources or the facility to dismantle, recycle and reuse of the construction materials, all very important aspects when faced with a broad and comprehensive perspective the problem of pollution and its impact on the planet. It is not enough just to train our architects in this aspect, but also that people who face the construction of a new building, or simply the reform or rehabilitation of an old one, are aware of the impact that each detail of that work will have on their own quality of life, on the consuming of energy and on the planet, through the carbon footprint that construction itself and its use and possible future pull down will entail.In addition, to what was indicated in the previous section, the goals of Europe 2020 establish the importance of motivating students to study science and prepare them to face the challenges that an ecological Europe implies, where new jobs will be created in the Green Economy sector (as identified in Skills for Green Jobs - CEDEFOP 2010). In this way, society needs future scientists with the necessary skills and knowledge to create healthy and sustainable cities.MAIN OBJECTIVEThe EcoBuild Project focuses on young students between 12 and 16 years old and provides them with the necessary awareness and knowledge about these new concepts, such as the carbon footprint, the recyclability of construction materials and all materials in general, the consumption of water or the acidification of the land. This goal will be achieved through the development and implementation of an EDUCATIONAL SERIOUS GAME and an ONLINE RESOURCE CENTRE (ORC) in the secondary schools, as well as through the development of a series of awareness and learning activities that are intended to be carried out throughout the project, in which students will play to be ecological builders and at the same time researchers in matters of ecology and environment.Through the EcoBuild Game, students can make their own virtual constructions, which using real parameters will give the estimated impact in terms of carbon footprint based on the use of the different materials and construction techniques for building. The most common materials and techniques being used currently in European countries will be included in the game, incorporating the most important parameters in terms of environmental impact, not only relating to the energy consumption of the resulting building, but also due to the extraction of the materials, their future recycling, its duration, capacity for reuse, etc. It does not pretend to be a tool to train them to becomearchitects, but to make them be aware of the importance of reducing the impact on the environment by selecting the right construction materials and techniques.RESULTSThe main results expected during the project on its completion will be the following:- An Online Resource Centre will be designed and produced to support the implementation of all the training materials produced about educational ecology in construction.- The Serious Games EcoBuild. The interface aspect will model oneself on the famous videogame SIMS (where young are familiar with this type of videogame), but with an very important difference at educational level in the construction aspect and tools of this videogame, where a student, as he/she builds a building and chooses the different materials, is aware of the pollution and the environmental impact they generate through easily understood visual comparisons that generate impact on the student.IMPACTRegarding the impact of the project, although initially the project aims to achieve a direct impact on students who are in secondary education, through them, this impact will be also transferred to society in general. They will work as transmitters to society of this knowledge and awareness raising. In addition, many of the actions to be developed will also involve, and then impact, authorities at different levels, NGOs, neighbourhood associations and others.
