Energy efficiency, advanced controls and renewable energy systems for operating industrial, residentialand tertiary sector buildings designed to be Near-Zero Energy are investigated to explore the perfor-mance gap. The analysis involves a comparison of energy dynamic and quasi-dynamic models with datafrom smart monitoring systems, indoor and outdoor environment measurements, power consumptionand production data. Specific issues and conclusions have been drawn as the basis for addressing the per-formance gap between energy efficiency prediction in the design phase and measurements’ evaluationin operational phase

The emerging paradigm of sustainability represents a challenging field in terms of new technologies, market regulations, and business models. Limits of both linear industrial development and consumerist way of living have been clearly identified since the late 1960s by the first systemic studies on the effect of human activities on Earth. Many contributions from different disciplines have paved the way for an open, participated, and responsible innovation approach, which is presently triggering the transition toward a nonexploitative human development. An anticipation of this conceptual framework can be found in Joseph Beuys’ art, which can still represent a source of inspiration for innovators, entrepreneurs, economists, and community leaders. In his artistic legacy—from the six blackboards of Perugia to the 7000 Oaks of Kassel—Beuys is still asking us to transform our everyday actions, joining the collective effort toward a new evolutionary stage of humanity, founded upon a holistic vision of society and nature.

Smart grids are one of the major challenges of the energy sector for both the energy demand and energy supply in smart communities and cities. Grid connected energy storage systems are regarded as promising solutions for providing ancillary services to electricity networks and to play an important role in the development of smart grids. The aim of the present article is to analyze the role of storage systems in the development of smart grids. The article includes an analysis and a list of energy storage systems that are applied in smart grids. Various energy storage systems are examined raging from electrical, electrochemical, thermal, and mechanical systems. Two case studies are presented that show the role of energy storage in effective management of energy demand and supply.

The modernization, efficiency, and decarbonization of the energy supply systems are among the new challenges to be faced in the coming decades to achieve the targets and objectives dictated by European strategic policies. Despite the countless benefits related to renewable energy sources (RES) integration, this brings key challenges to the power system, such as the risk of imbalance between energy generation and demand, sudden changes in flows in transmission lines with a need for expensive and time-consuming upgrades, and the withdrawal of conventional generation systems with consequent demands for new solutions and innovation to support grid services. A potential solution to limit the huge intermittence and fluctuation in power generation from RES is Concentrated Solar Power (CSP) technology integrated with thermal energy storage. The aim of this paper is to discuss the potential benefits related to the use of CSP technology by presenting innovative industrial solutions developed in the Italian SOLARGRID Project, namely the hybridization of CSP–PV systems and the solar thermo-electric system developed by MAGALDI, the parabolic trough collector of Eni, and the new linear Fresnel reflector configuration of IDEA S.r.l. These plant and component solutions are developed for improving the technical performance of CSP technology and reducing the levelized cost of electricity, thereby fostering an effective and massive deployment and encouraging the creation of new business models.

Solar concentration systems are usually deployed in large open spaces for electricity generation; they are rarely used to address the pressing energy needs of the built environment sector. Fresnel technology offers interesting and challenging CSP energy pathways suitable for the built environment, due to its relatively light weight (<30 kg.m⁻²) and low windage. The Cyprus Institute (CyI) and Consorzio ARCA are cooperating in such a research program; we report here the construction and integration of a 71kW Fresnel CSP system into the HVAC (Heating, Ventilation, and Air Conditioning) system of a recently constructed office & laboratory building, the Novel Technologies Laboratory (NTL). The multi-generative system will support cooling, heating and hot water production feeding the system of the NTL building, as a demonstration project, part of the STS-MED program (Small Scale Thermal Solar District Units for Mediterranean Communities) financed by the European Commission under the European Neighbourhood and Partnership Instrument (ENPI), CBCMED program.
