JRC Implementation Review 2017: In the context of the interim evaluation of the Horizon 2020 Programme

This report presents an external assessment of the follow-up that the JRC has given to the ex-post evaluation of its direct actions under the Seventh Framework Programme (FP7) conducted in 2015. The report addresses the new JRC 2030 strategy and the adaptation of the organisational structure in July 2016. The evaluation panel compliments the organisation and its leadership on the work in the design of the strategy, in gathering the support and adapting the organisational structure for the implementation of the strategy. In relatively short time the JRC went through the biggest change since the introduction of its policy-support mission in the Fifth Framework Programme in 1998. The panel notes the enthusiasm and the impressive speed with which the JRC has implemented a large number of improvements (Chapter 2). Having seen so many parts of the renewed organisation, the panel also had a critical look at the change (Chapter 3), and gives three general recommendations for further development of the JRC (Chapter 4). - Keep focus on excellence in science - Connect the whole organisation to the transformation - A modern JRC merits modern governanceJRC.DDG2-Deputy Director-General in charge of Directorates B,C,D,E,F,

An Epistemic-Deontic-Axiologic (EDA) agent-based Energy Management System in office buildings

In the UK, buildings contribute about one third of the energy-related greenhouse gas emissions. Space heating and cooling systems are among the biggest energy consumers in buildings. This research aims to develop a novel Building Energy Management System (BEMS) to reduce the energy consumption of the heating, ventilation and air-conditioning (HVAC) system while fulfilling each occupant’ thermal comfort requirement. This paper presents a newly developed novel method, Epistemic-Deontic-Axiologic (EDA) Agent-based solution to support the Energy Management System meeting the dual targets of occupant thermal comfort and energy efficiency. The multi-agent solutions are applied to the BEMS. The problem decomposition method is used to define the architecture of the system. The Epistemic-Deontic-Axiologic (EDA) agent model is applied to develop the rational local and personal agents inside the system. These EDA-based agents select their optimal action plan by considering the occupants’ thermal sensations, their behavioural adaptations and the energy consumption of the HVAC system. The Newly-developed personal thermal sensation models and group-of-people-based thermal sensation models generated by support vector machine (SVM) based algorithms are applied to evaluate the occupants’ thermal sensations. These models are developed from the data collected in a real built environment. Simulation results prove that the newly-developed BEMS can help the HVAC system reduce the energy consumption by up to 10% while fulfilling the occupants’ thermal comfort requirements

An experimental and theoretical investigation of the extent of bypass air within data centres employing aisle containment, and its impact on power consumption

A combination of laboratory experiments and a system model are used to carry out the first investigation into the potential for cold air to bypass IT equipment within data centres (DCs) employing aisle containment, and the effect of this bypass on DC electricity consumption. The laboratory experiments involved applying a differential pressure across commercially available server racks and aisle containment systems and measuring the resulting air flow. The potential to minimise bypass by sealing leakage paths and redesigning racks was investigated and quantified experimentally. A new system model is developed using a combination of manufacturer data, empirical relationships and experimental results to predict the impact of bypass on the power consumption of the various components of a DC's cooling infrastructure. The results show that, at typical cold aisle pressures, as much as 20% of the supplied air may bypass servers by finding alternate paths through the server rack itself. This increases the required flow rate from air conditioning units (ACUs). The system model predicts that: (i) practical measures undertaken to reduce this bypass could reduce total power consumption by up to 8.8% and (ii) excessive pressure differentials across the containment system could also increase power consumption, by up to 16%

Energy-saving potential of large housing stocks of listed buildings, case study: l'Eixample of Valencia

[EN] A significant part of the European residential building stock is architectural heritage and is protected by law in different grades. Although these dwellings seldom fulfil the current eco-efficiency requirements, listed buildings are exempt from energy regulations requirements. This paper reviews the constructional characteristics common to 588 multi-storey listed buildings (circa 6000 dwellings) located in l'Eixample district in Valencia (Spain). The poor thermal performance of these buildings proven by this study reveal a significant potential for saving energy and reducing CO2 emissions, particularly when considering the current requirements fixed by the current Spanish building code. Retrofitting measures intended to improve the thermal behaviour of these buildings, while being respectful to their listed nature, are proposed and assessed in terms of energy demand, air pollution and economy.Perez-Garcia, A.; Guardiola, AP.; Gómez-Martínez, F.; Guardiola Villora, AP.
