The proposed project will develop and demonstrate energy efficient new and innovative technologies and solutions for retrofitting and performance monitoring of a number of typical residential buildings in EU countries. Technologies envisaged for envelope retrofitting include various types of insulation materials. Energy efficient solutions will also be deployed including energy efficient lighting and HVAC, and renewable energy systems. The technologies and solutions will be affordable, durable, easy for installation and compatible with existing building functions and aesthetics as well as energy efficient. The types of building for retrofitting will include detached, semidetached and terrace houses, and flats of different ages. Methods for measurement of building performance before and after retrofitting will include leakage test and thermal imaging to determine the major areas of building envelope for improvement, in addition to smart energy metering for individual technologies and building as a whole. The buildings will be retrofitted to at least the latest national building standards for new buildings. The type and number of technology deployed will be optimised using life cycle energy analysis for each type of building. The work programme will involve development of computer models for optimising technologies and solutions, analysing dynamic energy demand of buildings and predicting microclimate indoors, development and testing of technologies and solutions under laboratory conditions, retrofitting and monitoring residential buildings in different climatic conditions, and a socio-economic analysis. The above outcomes will be delivered through innovative solutions developed by a Consortium comprising leading companies, universities and public institutions from 10 European countries.

The growing share of variable renewable energy necessitates flexibility in the electricity system, which flexible energy generation, demand side participation and energy storage systems can provide. SIMBLOCK will develop innovative demand response (DR) services for smaller residential and commercial customers, implement and test these services in three pilot sites and transfer successful DR models to customers of Project partners in further European countries. The pilot sites are blocks of highly energy efficient buildings with a diverse range of renewable and cogeneration supply systems and requisite ICT infrastructure that allows direct testing of DR strategies. SIMBLOCKs main objectives are to specify the technical characteristics of the demand flexibility that will enable dynamic DR; to study the optimal use of the DR capability in the context of market tariffs and RES supply fluctuations; and to develop and implement market access and business models for DR models offered by blocks of buildings with a focus on shifting power to heat applications and optimization of the available energy vectors in buildings. Actions toward achieving these objectives include: quantifying the reliability of bundled flexibility of smaller buildings via pilot site monitoring schemes; combining innovative automated modelling and optimization services with big data analytics to deliver the best real time DR actions, including motivational user interfaces and activation programs; and developing new DR services that take into account the role of pricing, cost effectiveness, data policies, regulations, and market barriers to attain the critical mass needed to effectively access electricity markets. SIMBLOCKs approach supports the Work Program by maximizing the contribution of buildings and occupants and combining decentralized energy management technology at the blocks of building scale to enable DR, thereby illustrating the benefits achievable (e.g. efficiency, user engagement, cost).

Most of the energy consumption in Europe is due to heating and cooling used for domestic, tertiary and industrial purposes; This energy is largely produced by directly burning fossil fuels with a negative environmental impact. RES directive and the SET Plan focuses its attention on the use of RES to drive systems for heating and cooling in order to reduce greenhouse gas emissions and the dependence on energy import, and to reach the 20/20/20 target. For this reason the European Unions energy policy gives high priority to energy savings and use of renewable energy sources. The project iNSPiRe aims at conceiving, developing and demonstrating Systemic Renovation Packages, through the innovative integration of envelope technologies, energy generation (including RES integration), energy distribution, lighting and comfort management systems into deep energy renovation of buildings, both in the residential and tertiary sectors. During the project Multifunctional Industrialized Renovation Kits will be developed, manufactured and installed at three Demo Case Studies. The optimal integration of such systems will lead to major cumulative energy savings with respect to consumption prior to renovation (therefore to extreme reductions of the CO2 emissions), assuring at the same time enhanced users comfort conditions. The final target of the systemic renovation packages will be to reach an overall Primary Energy consumption of the building lower than 50 kWh/m/year. The project iNSPiRe triggers a scenario of fast decarbonization, by promoting the transition of the construction sector to a fully industrial phase, hence optimizing the materials utilization and manufacturing/installation/maintenance/ dismantling processes. The exploitation of the project results will make available on the market reliable and cost-effective products, suitable for the deep energy renovation of existing buildings, fostering the connection between construction and industry sectors, and creating new jobs.

Since several processes working with solar energy are available, a study to know which technology is more suitable considering the primary energy consumption and economy is necessary. This paper has as objectives the primary energy analysis and economic evaluation of solar thermal and photovoltaic cooling systems used for the air conditioning in office buildings applying simulation systems. Due to the climatic conditions influence on the performance of these two systems, the comparison is made for three different climates corresponding to Palermo, Madrid and Stuttgart. For each climate the same geometry and dimensions of a building are considered but with different user profiles and construction, consequently different heating and cooling loads, in total 12 cases are taken into consideration. The consumption of electricity is favored with the electricity produced by the photovoltaic modules, which covers in some of the studied cases almost the half of the total energy demand, therefore the relative primary energy savings reaches 50%, while in the case of the solar thermal system, the relative primary energy savings reaches 37% in Palermo, 36% in Madrid, and 29% in Stuttgart. Hence, simulations to determine the best work parameters in each place are suggested for the reduction of energy demands and a sensitivity analysis is presented. © 2013 Elsevier B.V.

The main idea of InSun is to demonstrate the reliability and quality of large scale solar thermal systems for different types of industrial process heat applications on medium and high temperature levels. Three different types of collector systems are demonstrated and compared: improved flat plate collectors for an Austrian meat factory for steam pre-heating up to 95C, tracked concentrating Fresnel collectors for an Italian brick drying factory at 200C, and parabolic trough collectors for milk powder production at 185C in Spain. Each of these applications offers a high replication potential. Missing standards especially for concentrating collectors and the large uncertainty of system integration costs are the main bottlenecks for a fast system deployment in the industrial sector. Therefore, the project aims to give a significant input to the standardization process in terms of construction, integration and dimensioning of this young and innovative technology which will be supported by the foundation of a special interest group for lobbying work including key members of the relevant collector producers and research organizations. The industrial driven management board of InSun ensures a strong and continuous participation of the industrial partners involved. This management board will be responsible for the observation of the progress and quality of the demonstration projects, for the quality assurance of dissemination activities and of support actions pushing the standardization process and to lead the market deployment strategy development tasks. Three periodically organized international expert workshops with strong support from ESTIF (see attached letter of support) will include selected external experts from other ongoing research or commercial projects. Furthermore, InSun aims to contribute to the IEA Task 49 and Task 45.

The CI-NERGY Marie Curie Initial Training Network (ITN) aims to train young scientists to develop urban decision making and operational optimisation software tools to minimise non-renewable energy use in cities. The training will be carried out by a close collaboration of six of the best academic research centres and four leading industrial companies from the energy and software technology sector (Siemens, WienEnergie, EDF/EIFER, and IES). The research fellows will apply their results in two case study cities (Geneva and Vienna), which were chosen for their very ambitious sustainability goals. The CI-NERGY network will be a highly multi-disciplinary coordinated PhD programme on urban energy sustainability, covering the key challenges in cities related to a low carbon future. There is a gap in high level integrated training in the urban energy research field, which is due to the wide range of fragmented disciplines from building physics and energy supply technologies with electrical and thermal engineering up to software engineering and information technology. The CI-NERGY network wide training provided by excellent academic and industry partners from all areas of smart cities will close this gap. The impact of the network training activities will be highly noticeable for energy supply utilities, IT companies, policy makers, urban planners, researchers on sustainable urban energy systems and finally the inhabitants of cities themselves. All sectors mentioned will provide excellent career opportunities for the research fellows, who will gain excellent knowledge of the sectorial requirements by a structured secondment plan.

District Heating and Cooling networks distribute energy from a centralized generation plant to a number of remote customers. As such, actual DHC systems suffer from significant heat losses highly unexplored integration potential of different available energy sources (e.g. renewables and waste heat) into the network high installation costs. FLEXYNETS will develop, demonstrate and deploy a new generation of intelligent district heating and cooling networks that reduce energy transportation losses by working at neutral temperature levels. Reversible heat pumps and chillers will be used to exchange heat with the DHC network on the demand side. In this way, the same network can provide contemporary heating and cooling. FLEXYNETS solutions will integrate effectively multiple generation sources (including high- and low-temperature solar thermal, biomass, PV, cogeneration and waste heat) where they are available along the DHC network, by managing energy at different temperature levels and assuring optimized exergy exploitation. Together with storages, control strategies that optimize the harvest of renewable energy sources are key from the technical and economic points of view. On the one hand, strategies will be assessed that assure a thermal balance among diffused heat generation, storage and utilization. On the other, policies will be elaborated to decide when energy is to be gathered locally or exchanged (both purchased and sold) with the electricity and gas networks. The optimal management of such new generation networks will lead to a synergic effect on primary energy savings (hence on the reduction of the CO2 emissions), assuring at the same time investment and operation profitability. As such, FLEXYNETS will contribute to a higher penetration of smart DHC networks on the heating and cooling market, and will contribute to the European recovery plan.

The advancement of project management (PM) knowledge and the development of PM capability of people is crucial to the successful delivery of projects. As the overall project-related spending in the EU is assumed to be about 3.27 trillion there are huge societal and economic challenges of reducing the massive financial and psychological costs of poor project delivery. Especially as about 6% of all projects are believed to be wholly unsuccessful, many of them tax-payer funded. Our programme is designed to put building blocks in place to enable PM to respond to the challenges it faces in delivering projects successfully in the 21st century. It does this by taking a multi-disciplinary perspective encompassing PM, lean management, psycho-social aspects, innovation and change management. The building blocks will have three broad pillars: one focused on PM efficiency (being Lean), one on PM systems that meet the psycho-social needs of project staff (being Seen) and one on making PM responsive to the need of organisations to be innovative and manage change (being Lean and Seen). The programme will cater for different contexts of project delivery in developed and developing countries, to reflect the global and interconnectedness nature of projects. A network of five academic partners, including one from a developing country and five non-academic, will deliver the holistic PM framework to guide project delivery in the future. They will investigate the role of different management practices in PM contexts and the distinctions in PM system design and delivery in different contexts. Data will be collected through a multiple method approach including in-depth reviews of the literatures, secondary data sources, cross-sectional surveys, case studies, focus groups, Delphi and interviews. Innovation will take place by bringing together the knowledge of theoretical perspectives from different disciplines, which largely reside in the academic partners, with the practical knowledge

Modern enterprise systems have to comply to regulations such as Basel III resulting in complex security requirements. These requirements need to be modeled at design-time and enforced at runtime. Moreover, modern enterprise systems are often business-process driven, i.e., the system behavior is described as high-level business processes that are executed by a business process execution engine. Consequently, there is a need for an integrated and tool-supported methodology that allows for specifying and enforcing compliance and security requirements for business process-driven enterprise systems. In this paper, we present a tool chain supporting both the design-time modeling as well as the run-time enforcement of security requirements for business process-driven systems. Copyright 2012 ACM.
