Keywords: Building Renovation and Regeneration, Decarbonization of buildings, Near Zero Emission Buildings, Smart building technologies IoT Platform
Abstract: In Europe the building sector is responsible for nearly 40% of the total energy consumption, and more than 75% of the building stock is inefficient in light of current standards. The EU and the Member States have targeted existing and new buildings through various policy instruments, from normative through informational and to market-based policies, building codes and appliance standards have had profound market transformational effects across the EU. In this paper the state of the art of the EU building sector is presented and the main results of a 2 years R&D project implemented in Italy are illustrated.

Autores: G. FABBRI, A. DAPIT
Keywords: Public Private Partnerships, Building Renovation and Regeneration, Public cultural heritage Management, Conservation and Valorisation
Abstract: Municipalities typically face difficulties in conserving and managing their public cultural heritage, which often lingers in a condition of neglect, and there is a strong need to identify a set of additional and innovative tools capable of providing adequate financial resources as well as new skills. The use or reuse of public cultural heritage buildings can be managed through the adoption of Public–Private agreements and novel models. The paper illustrates the new 5P concept model of Public-Private-People-Policy-Partnerships that has emerged as a way to address the problems related to Public-Private Partnerships by bringing the citizens (People) into the Partnerships alongside with Public and Private actors and with the strategic local Policy makers (Policy). The paper illustrates a practical case of applying the model to a R&D green building project.

Keywords: Waste Water Treatment Plants, Chemical Portable Toilets, Use of sludges in agriculture.
Abstract: The EU wastewater management industry is continuously looking for innovative technological solutions that can enter the market with a reduced environmental impact. This paper focuses on the problems associated to the disposal of human waste and on the specific market of the so-called mobile toilets. These are independent portable units equipped with sanitary tools that use chemical agents to disinfect the vessel and not connected to the sewer network. With growing awareness towards effective sanitation, mobile toilets have gained immense popularity in recent years and are now widely used at construction sites, event venues, public places, and in several other application like temporary refugee housing, migrants’ camps, military missions, cases of natural disasters, airplanes, trains, campers, caravans and campsites. This paper illustrates a new process for the disposal of organic waste from mobile toilets.

Keywords: Home Automation, Emulation, KNX, Multimedia Web Components, IoT, COScore infrastructure
Abstract: The Internet of Things mechanisms enable the management of home environments since they can be developed as IoT based information systems. From standard smart homes to automated buildings, including other kind of domotics and inmotics solutions, every system must be tested and validated before its installation. The current tools offered by IoT and home automation vendors lack in emulation features close to the real behavior of the devices. In many cases, delaying the verification actions until the hardware is acquired and installed may cause some drawbacks, for example, from the economic point of view. This paper presents a solution for emulating home automation environments which are based on the KNX standard and can be represented by architectures of devices. The emulation consist of developing virtual implementations of real devices which operate and communicate through web technology. The technology implementing these virtual devices allows us to develop components which can provide different type of data related to the installation (audio, video, text, animations, images, etc.). The architectures can be managed using web services and their behavior can be tested through web user interfaces showing the mentioned data. Furthermore, virtual and physical devices are connected to validate the interoperability between the real installation and the emulation.

Autores: A.J. Fernández-García, L. Iribarne, A. Corral, J. Criado, J.Z. Wang.
Keywords: Machine learning, Recommender Systems, Feature engineering, Feature Selection, Component-based interfaces, interaction information acquisition.
Abstract: Software designers are striving to create software that adapts to their users’ requirements. To this end, the development of component-based interfaces that users can compound and customize according to their needs is increasing. However, the success of these applications is highly dependent on the users’ ability to locate the components useful for them, because there are often too many to choose from. We propose an approach to address the problem of suggesting the most suitable components for each user at each moment, by creating a recommender system using intelligent data analysis methods. Once we have gathered the interaction data and built a dataset, we address the problem of transforming an original dataset from a real component-based application to an optimized dataset to apply machine learning algorithms through the application of feature engineering techniques and feature selection methods. Moreover, many aspects, such as contextual information, the use of the application across several devices with many forms of interaction, or the passage of time (components are added or removed over time), are taken into consideration. Once the dataset is optimized, several machine learning algorithms are applied to create recommendation systems. A series of experiments that create recommendation models are conducted applying several machine learning algorithms to the optimized dataset (before and after applying feature selection methods) to determine which recommender model obtains a higher accuracy. Thus, through the deployment of the recommendation system that has better results, the likelihood of success of a component-based application is increased by allowing users to find the most suitable components for them, enhancing their user experience and the application engagement.

Autores: D. Alulema, J. Criado, L. Iribarne.
Keywords: Internet of Things, T-health, digital TV, model engineering, security
Abstract: The Internet of Things has presented a rapid development, due to the over-crowding of hardware and software platforms, greater deployment of communications networks, development of data analysis tools, among others. This development has led to a boom in applications focused on areas as varied as Smart Cities, Smart Agro, Smart Buildings, Smart Home, and Smart Health, in which people and things are interconnected. This is one of the reasons by which a review of the main technologies involved in the emergence of the Internet of Things must be carried out to determine those characteristics allowing that interconnection, but without neglecting security. This issue allows the user to feel con dent to use these new services. In this work, we propose a cross-device architecture that integrates technologies and implementations in homes, and uses basic authentication as a security scheme. To validate the cross-device proposal, a case study scenario has been designed, including and integrating digital-TV (DTV), Smart Phones and wearables devices for monitoring users physical activity.

Autores: M. Espínola, J.A. Piedra, R. Ayala, L. Iribarne, S. Leguizamon, J.Z. Wang.
Keywords: Cellular automata, Remote sensing, DEM satellite images, Water simulation
Abstract: Remote sensing has been used in numerous environmental simulations with the aim of solving and improving many different kinds of problems, e.g., meteorology applications, soil quality studies, water resource exploration, and environmental protection. Besides, cellular automata have been widely used in the field of remote sensing for simulating natural phenomena over two-dimensional satellite images. However, simulations on Digital Elevation Models (DEM), or three-dimensional (3D) satellite images, are scarce. This paper presents a study of modeling and simulation of the weather phenomena of rainfall, water evaporation and groundwater flow in 3D satellite images through a new algorithm, developed by the authors, named RACA (RAinfall with Cellular Automata). The purpose of RACA is to obtain, from the simulation, numerical and 3D results related to the total cumulative flow and maximum level of water that allow us to make decisions on important issues such as analyzing how climate change will affect the water level in a particular area, estimating the future water supply of a population, establishing future construction projects and urban planning away from locations with high probability of flooding, or preventing the destruction of property and human life from future natural disasters in urban areas with probability of flooding.
D2R-TED: Data—Domain ReductionModel for Threshold-Based Event Detection in Sensor Networks
Autores: Fernando Leon-Garcia, Jose Manuel Palomares and Joaquin Olivares
Keywords: WSN; event detection; data compression
Abstract: The reduction of sensor network traffic has become a scientific challenge. Different compression techniques are applied for this purpose, offering general solutions which try to minimize the loss of information. Here, a new proposal for traffic reduction by redefining the domains of the sensor data is presented. A configurable data reduction model is proposed focused on periodic duty–cycled sensor networks with events triggered by threshold. The loss of information produced by the model is analyzed in this paper in the context of event detection, an unusual approach leading to a set of specific metrics that enable the evaluation of the model in terms of traffic savings, precision, and recall. Different model configurations are tested with two experimental cases, whose input data are extracted from an extensive set of real data. In particular, two new versions of Send–on–Delta (SoD) and Predictive Sampling (PS) have been designed and implemented in the proposed data–domain reduction for threshold–based event detection (D2R-TED) model. The obtained results illustrate the potential usefulness of analyzing different model configurations to obtain a cost–benefit curve, in terms of traffic savings and quality of the response. Experiments show an average reduction of 76% of network packages with an error of less than 1%. In addition, experiments show that the methods designed under the proposed D2R–TED model outperform the original event–triggered SoD and PS methods by 10% and 16% of the traffic savings, respectively. This model is useful to avoid network bottlenecks by applying the optimal configuration in each situation

Keywords: Road safety, Road maintenance, Crack detection,
Pavement crack, Automatic detection, Heuristic classifier
Abstract: Each year, millions of dollars are invested on road maintenance and reparation all over the world. In order to minimize costs, one of the main aspects is the early detection of those flaws. Different types of cracks require different types of repairs; therefore, not only a crack detection is required but a crack type classification. Also, the earlier the crack is detected, the cheaper the reparation is. Once the images are captured, several processes are applied in order to extract the main characteristics for emphasizing the cracks (logarithmic transformation, bilateral filter, Canny algorithm, and a morphological filter). After image preprocessing, a decision tree heuristic algorithm is applied to finally classify the image. This work obtained an average of 88% of success detecting cracks and an 80% of success detecting the type of the crack. It could be implemented in a vehicle traveling as fast as 130 kmh or 81 mph.

Autores: E. Brunori, M.Maesano, F.V. Moresi, G. Scarascia Mugnozza, R. Biasi
Keywords: Precision Agriculture, Sustainable Viticulture, Remote Sensing Platforms
Abstract: Nowadays, agriculture faces new challenges and threats, some of the most important being related to environmental and climate issues. In the specific case of viticulture, according to the International Organization of Vine and Wine, EU is the world leading producer and exporter of wine and still encompasses the largest vineyard area in the world (38%) representing 20% of total agricultural employment in the EU (being mainly composed of small producers). The critical environmental impacts of grape production come from the intense use of pesticides, from the very high variability of the amount of fertilizers and from energy consumption related to the application of fertilizers and pesticides and for irrigation, pruning and tillage which are normally done with diesel tractors. The aim of the study is to present some results of the project ‘AgriDrone vision’. The main objectives of project were to assess the potential use of remote sensing platforms (aerial and/or terrestrial) to determine vines’ physiological status (e.g. water stress) during the growing season thereby proving temporal and spatial vine performances by proximal (field) no-destructive measurements.
