En cuanto al medio ambiente, se centra en el conocimiento de los aspectos normativos y de legislación estatal y europea, sin entrar a analizar en detalle los aspectos relacionados con la preservación, la contaminación en sus diversos aspectos y la eliminación de fuentes de riesgos. En cuanto a la tecnología energética, pretende dar a conocer las diferentes fuentes de energía, los combustibles, la combustión como fuente de obtención de energía térmica y su utilización para la obtención de energía mecánica y eléctrica mediante las máquinas térmicas directas (motores de combustión interna, turbinas de gas y turbinas de vapor), las máquinas inversas o de refrigeración, así como la obtención conjunta de calor y electricidad mediante la utilización de la cogeneración.

The later phase always depend of this first stages. Into this initial studies, one of the most important preocupation is to improve the energy response of the buildings. This paper introduces a program developed in order to do this primary energy studies. Another aims of this development are increase the productivity of the designer tasks and achieve better quality levels in buildings.

One third of a network’s energy is required for operating the subsystems of metro stations and surroundings, such as ventilation, vertical transportation and lightning. Although a relatively small percentage of energy can be saved with an optimal management of these subsystems, a large energy saving in absolute terms can be obtained. The objective of SEAM4US project is to develop advanced technologies for optimal and scalable control of metro stations that will generate at least 5% saving in non-traction electricity consumption in one year. The SEAM4US system, and the demonstrating pilot running on the Passeig de Gracia Metro station in Barcelona, represent a significant contribution and drive to the opening of new markets by developing and prototyping new ICT-intensive approaches to energy saving for underground spaces, generally, and, more specifical...

Those equations do not enable to introduce to the system uncertainties such as the sensor measurement error. In this paper, the use of the stochastic differential equations based on the CO2 tracer-gas mass balance are presented to obtain the air ventilation flows in a room introducing uncertainty elements. This kind of modeling, also known as grey-box modeling, combines physical knowledge of the system and information embedded in the monitored data to identify a suitable parametrization of the differential equation used. Finally, a set of statistical tests are used to assess the model's accuracy. Models that fulfill the tests are considered correct, and as a consequence, its parametrization too. Having the parametrization a physical meaning, it is possible to obtain the air ventilation flow of the room. Results show the viability of this kind of approach.Postprint (published version

Most educational buildings rely only on natural ventilation, making indoor air quality highly dependent on weather conditions. Therefore, to ensure the safety and well-being of students and teachers, it is necessary to determine the factors influencing CO2 concentration in naturally ventilated spaces. The aim of this paper is to estimate the students' CO2 emission rates in naturally ventilated classrooms using grey box models.

Although difficult to quantify, individuals' attitudes to energy use significantly impact the energy consumed in households. In this context, serious games provide an opportunity to enhance buildings' energy efficiency through changes in users' behaviour. This chapter presents the results obtained in the EnerGAware-Energy Game for Awareness of energy efficiency in social housing communities project (2015–2018), funded by EU H2020. The project developed a serious game for household energy efficiency called “Energy Cat: The House of Tomorrow.” The game was deployed and tested in a UK social housing pilot for one year. Cost-benefit analysis in the energy, environmental, and economic domains prove that serious gaming is among the most cost-effective energy efficiency strategies for households on the market.

It will integrate vast amounts of content from diverse repositories created in several large projects in the past, and build a frame- work for providing community-based services such as finding, acquiring, using and discussing about e-learning contents that were previously not reachable. Furthermore, MACE aims at providing innovative tools to search, create content and enrich it with new metadata, which can be used to support different learning scenarios. Several kinds of metadata are used in these tools to provide different perspectives on the learning content, and find new ways to combine them
