Item Energy demand prediction for the implementation of an energy tariff emulator to trigger demand response in buildings(2019-08-13) Noyé, Sarah; Saralegui, Unai; Rey, Raphael; Anton, Miguel Angel; Romero, Ander; Tecnalia Research & Innovation; DIGITALIZACIÓN Y AUTOMATIZACIÓN DE LA CONSTRUCCIÓN; EDIFICACIÓN DE ENERGÍA POSITIVABuildings are key actors of the electrical gird. As such they have an important role to play in grid stabilization, especially in a context where renewable energies are mandated to become an increasingly important part of the energy mix. Demand response provides a mechanism to reduce or displace electrical demand to better match electrical production. Buildings can be a pool of flexibility for the grid to operate more efficiently. One of the ways to obtain flexibility from building managers and building users is the introduction of variable energy prices which evolve depending on the expected load and energy generation. In the proposed scenario, the wholesale energy price of electricity, a load prediction, and the elasticity of consumers are used by an energy tariff emulator to predict prices to trigger end user flexibility. In this paper, a cluster analysis to classify users is performed and an aggregated energy prediction is realised using Random Forest machine learning algorithm.Item Energy efficiency compared studies at Master plan stage for a new urban development in Madrid(University College Dublin, 2008) Arellano, Jesús; Irastorza, Luis; Rodríguez, Francisco; Romero, Ander; LABORATORIO DE TRANSFORMACIÓN URBANA; EDIFICACIÓN DE ENERGÍA POSITIVAIn order to achieve optimum results, energy efficiency of buildings should be first addressed in the pre-design phase. This paper describes the studies carried out in order to improve the energy efficiency of the buildings planned to be built in a large residential-commercial urban development in the north of Madrid. The first analyses are addressed at Master plan design stage, confronting the issue of energy efficient building form. Following selection of four residential and office plots, several mass options, derived from the tight planning regulations for the area, are modelled and simulated in order to compare the results in terms of heating and cooling demand, taking into account each building's surroundings. Once the most efficient mass options are chosen, further studies, centred in envelope materials and building refrigeration and heating systems will be carried out, so the results obtained in all these areas can be used as criteria and specification guides from the early stages of individual building design projects.Item Integration of Real-Intelligence in Energy Management Systems to Enable Holistic Demand Response Optimization in Buildings and Districts(IEEE, 2018-10-18) Romero, Ander; de Agustin-Camacho, Pablo; Tsitsanis, Tasos; Tecnalia Research & Innovation; EDIFICACIÓN DE ENERGÍA POSITIVA; LABORATORIO DE TRANSFORMACIÓN URBANAAlthough multiple trials have been conducted demonstrating that demand side flexibility works and even though technology roll-out progresses significantly fast, the business application of residential and small tertiary demand response has been slow to develop. This paper introduces a holistic demand response optimization framework that enables significant energy costs reduction at the consumer side, while introducing buildings as a major contributor to energy networks' stability in response to network constraints and conditions. The backbone of the solution consists in a modular interoperability and data management framework that enables open standards-based communication along the demand response value chain. The solution is validated in four large-scale pilot sites, incorporating diverse building types, heterogeneous home, building and district energy systems and devices, a variety of energy carriers and spanning diverse climatic conditions, demographic and cultural characteristics.Item MOEEBIUS ENERGY PERFORMANCE OPTIMIZATION FRAMEWORK IN BUILDINGS FOR URBAN SUSTAINABILITY(2016-09) Romero, Ander; Tellado, Borja; Tsitsanis, Tasos; EDIFICACIÓN DE ENERGÍA POSITIVA; DIGITAL ENERGYWith the increasing demand for more energy efficient buildings, the construction and energy services industries are faced with the challenge to ensure that the energy performance and savings predicted during energy efficiency measures definition is actually achieved during operation. There is, however, significant evidence to suggest that buildings underperform illustrating a, so called, “performance gap” which is attributed to a variety of causal factors related to both predicted and in-use performance, implying that predictions tend to be unrealistically low whilst actual energy performance is usually unnecessarily high. In turn the successful penetration and effective application of ESCO business models relies on minimizing the gap between actual and predicted building energy performance. The aforementioned gap, though, prohibit the scaled deployment of energy efficiency projects constituting a significant barrier to the development of the ESCO market. The overall problem (performance gap) could be basically interpreted as an inability of current modelling techniques to represent the realistic use and operation of buildings. MOEEBIUS H2020 project introduces a Holistic Energy Performance Optimization Framework that enhances current (passive and active building elements) modelling approaches with advanced user behaviour modelling and machine learning technologies to create an innovative suite of end-user tools and applications enabling: (i) accurate Building Energy Performance prediction, (ii) precise allocation of detailed performance contributions between critical building components and operations, (iii) real-time building performance optimization, (iv) optimized retrofitting decision-making and, (v) real-time peak-load management optimization at the district level. Through the provision of a robust technological framework MOEEBIUS will enable the creation of attractive business opportunities for ESCOs, Aggregators, Maintenance and Facility Managers in evolving and highly competitive energy services markets.Item Multiscale building modelling and energy simulation support tools(CRC Press/Balkema, 2016-09) Romero, Ander; Izkara, Jose Luis; Mediavilla, Asier; Prieto, Iñaki; Pérez, Juan; Christodoulou, Symeon E.; Scherer, Raimar; EDIFICACIÓN DE ENERGÍA POSITIVA; LABORATORIO DE TRANSFORMACIÓN URBANA; DIGITALIZACIÓN Y AUTOMATIZACIÓN DE LA CONSTRUCCIÓN; Tecnalia Research & InnovationBuilding and district modelling (BIM, CityGML…) are key technologies for the deployment of energy efficiency strategies at building and district level, from the initial stages of planning and design to the operation and maintenance ones. These technologies allow satisfying the interoperability requirements that fa-cilitate the cooperation among the multiple stakeholders and provide the framework to develop more intelli-gent tools. This paper introduces five complementary European R&D projects in which TECNALIA is col-laborating, very good examples of innovative systems based on these concepts. MOEEBIUS enhances passive and active building elements modelling approaches enabling improved building energy performance simula-tions. HOLISTEEC focuses on building multi-physical simulations considering the neighborhood context. FASUDIR exploits the high potential of GIS tools for urban sustainability analysis and accurate building en-ergy performance evaluation. EFFESUS integrates district and building scales in historic districts. OPTEEMAL develops a platform at district level, based on an IPD approach.Item Passive solar collector module for building facades (DE)(2009-12-29) Amundarain, Aitor; Campos, José María; Chica, José Antonio;
