Item Analysis of building energy upgrade technologies for implementing the dual energy efficiency and demand response scheme for non-residential buildings(2019-09) Macías, Olga; Noyé, Sarah; Tellado, Nagore; Torrens, Ignacio; de Agustin-Camacho, Pablo; Tsagkrasoulis, Dimosthenis; Bucur, Mircea; Southernwood, Jo; Tecnalia Research & InnovationThe continuous growth of renewable energy and the transition to a more de-centralised electricity generation adds significant complexity to balance power supply and demand in the grid. These imbalances are partially compensated by demand response programs, which represent a new business opportunity in the building sector, especially for ESCOs. Including demand response to their traditional energy efficiency-based business model adds an additional revenue stream that could potentially shorten payback periods of energy renovation projects. This paper introduces this new dual-services business model, and evaluates the potential suitability of HVAC, generation and storage technologies to ensure proposed energy efficiency and flexibility goals.Item Design of knowledge-based systems for automated deployment of building management services(2020-11) Schneider, Georg F.; Kontes, Georgios D.; Qiu, Haonan; Silva, Filipe J.; Bucur, Mircea; Malanik, Jakub; Schindler, Zdenek; Andriopolous, Panos; de Agustin-Camacho, Pablo; Romero-Amorrortu, Ander; Grün, Gunnar; Tecnalia Research & Innovation; LABORATORIO DE TRANSFORMACIÓN URBANA; EDIFICACIÓN DE ENERGÍA POSITIVADespite its high potential, the building's sector lags behind in reducing its energy demand. Tremendous savings can be achieved by deploying building management services during operation, however, the manual deployment of these services needs to be undertaken by experts and it is a tedious, time and cost consuming task. It requires detailed expert knowledge to match the diverse requirements of services with the present constellation of envelope, equipment and automation system in a target building. To enable the widespread deployment of these services, this knowledge-intensive task needs to be automated. Knowledge-based methods solve this task, however, their widespread adoption is hampered and solutions proposed in the past do not stick to basic principles of state of the art knowledge engineering methods. To fill this gap we present a novel methodological approach for the design of knowledge-based systems for the automated deployment of building management services. The approach covers the essential steps and best practices: (1) representation of terminological knowledge of a building and its systems based on well-established knowledge engineering methods; (2) representation and capturing of assertional knowledge on a real building portfolio based on open standards; and (3) use of the acquired knowledge for the automated deployment of building management services to increase the energy efficiency of buildings during operation. We validate the methodological approach by deploying it in a real-world large-scale European pilot on a diverse portfolio of buildings and a novel set of building management services. In addition, a novel ontology, which reuses and extends existing ontologies is presented.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 A new era in the energy performance of buildings(2017-11-01) de Agustin-Camacho, Pablo; Romero-Amorrortu, Ander; Krysinski, Dawid; Tecnalia Research & InnovationImproving energy efficiency in buildings is a major priority for the European Union, yet current modelling processes do not accurately reflect consumption. The MOEEBIUS framework will provide the basis for more accurate energy performance assessment, underpinning efforts to improve efficiency and opening up new commercial opportunities, as Dawid Krysiński explainsItem Plotting a path to reduce the energy performance gap(2019-04-08) de Agustin-Camacho, Pablo; Romero-Amorrortu, Ander; Kowalska, Agnieszka; Tecnalia Research & InnovationImproving energy efficiency performance in buildings is a major priority for the European Commission, with a target of achieving 20 percent energy savings by 2020. The EU promotes solutions which reduce energy consumption in the building sector to achieve this, an area which forms the primary research focus for the MOEEBIUS projectItem Simulation-Based Evaluation and Optimization of Control Strategies in Buildings(2018-12-01) Kontes, Georgios; Giannakis, Georgios; Sánchez, Víctor; de Agustin-Camacho, Pablo; Romero-Amorrortu, Ander; Panagiotidou, Natalia; Rovas, Dimitrios; Steiger, Simone; Mutschler, Christopher; Gruen, Gunnar; Tecnalia Research & Innovation; EDIFICACIÓN DE ENERGÍA POSITIVA; LABORATORIO DE TRANSFORMACIÓN URBANAOver the last several years, a great amount of research work has been focused on the development of model predictive control techniques for the indoor climate control of buildings, but, despite the promising results, this technology is still not adopted by the industry. One of the main reasons for this is the increased cost associated with the development and calibration (or identification) of mathematical models of special structure used for predicting future states of the building. We propose a methodology to overcome this obstacle by replacing these hand-engineered mathematical models with a thermal simulation model of the building developed using detailed thermal simulation engines such as EnergyPlus. As designing better controllers requires interacting with the simulation model, a central part of our methodology is the control improvement (or optimisation) module, facilitating two simulation-based control improvement methodologies: one based in multi-criteria decision analysis methods and the other based on state-space identification of dynamical systems using Gaussian process models and reinforcement learning. We evaluate the proposed methodology in a set of simulation-based experiments using the thermal simulation model of a real building located in Portugal. Our results indicate that the proposed methodology could be a viable alternative to model predictive control-based supervisory control in buildings.Item Transición energética hacia distritos sostenibles mediante nodos energéticos renovables(2019) Eguiarte-Fernández, Olaia; de Agustin-Camacho, Pablo; Uriarte, Amaia; Usobiaga, Elena; Tecnalia Research & InnovationActualmente, los edificios son los causantes del 36% de las emisiones de CO2 en Europa, lo que los convierte en uno de los objetivos principales de actuacion local para el cumplimiento de los objetivos energeticos y medioambientales de la Union Europea (UE). Para alcanzar la transicion hacia barrios sostenibles y neutros en carbono es necesaria una regeneracion urbana hacia los edificios de consumo casi nulo (nZEB) o incluso, siendo mas ambiciosos, edificios energeticamente positivos. Para conseguirlo, no solo se deben construir nuevos edificios para que cumplan estas exigencias, sino que el parque edificado actual debe ser rehabilitado con el fin de reducir su demanda energetica, la cual deberá ser cubierta en gran medida por energias renovables. Sin embargo, la integracion y gestion de algunas tecnologias, como la solar termica y fotovoltaica, en los edificios presentan un reto debido a la intermitencia de las mismas, el desajuste entre las horas de generacion y las de consumo en sectores como el residencial, o la disponibilidad de espacio para desplegarlas.
