In the current energy transition, Renewable Energy Sources are identified as key enablers for the achievement of the ambitious European target of climate neutrality by 2050; among them, solar and wind energy play a crucial role. The evolution of production, storage and end users’ technologies goes hand in hand with the rapid development of the information sector, where High Performance Computing (HPC) infrastructures allow the exploitation of Internet of Things devices and Artificial Intelligence techniques. The use of HPCs in the energy field enables the use, processing and sharing of large volumes of energy data. The funded by the CEF TELECOM 2018 DYDAS (Dynamic Data Analytics Services) Project is carried out in the above-mentioned framework, aiming to create a collaborative platform, called DYDAS, that, using high-performing computers, will offer data, algorithms and data analysis services to a wide range of final users, both private and public. More specifically the paper will focus on the Use Case Energy, whose objective is to test and validate the DYDAS platform, by exploiting meteorological forecast techniques and using satellite information to facilitate and boost up the assessment of both energy demand and power production. Considering the strong dependency on resource availability, the localization of the resources and the related infrastructure is essential for an efficient and strategic energy planning. Therefore, the mix of traditional algorithms, climatic variables and remote sensing techniques represents an added value for supporting decision-makers in the energy planning processes at local and national scales, taking advantage of the geomatics instruments to visualize and monitor decision strategies. Given the role of electricity in the energy transition, the current paper deepens the Use Case Energy focusing on power generation from photovoltaic plants and on-shore and off-shore wind farms located in Italy. The aim of the use case is to estimate the potential local power production, by collecting information about technical features and geo-localization of real plants, and integrating them with georeferenced climatic variables, which can influence the electricity production (e.g., air temperature, solar irradiance, etc.)., CLIMA 2022 conference, 2022: CLIMA 2022 The 14th REHVA HVAC World Congress

The improvement of buildings energy efficiency represents one of the key objectives of current European policy actions, in order to guide the transition towards a low-carbon society. Indeed, nowadays, it is known that the building sector is responsible for 40% of total energy consumption and that heating is recognised as the main cause of this impact. In this context, heat pumps are recognized as promising solutions both for new constructions and for the renovation of existing buildings. For supporting the transition of the building sector, in Italy, within the “Recovery Decree” (D.L. 34/2020), which has introduced diverse social policies and financial support schemes to face the economic crisis following the COVID-19 pandemic, it is worth mentioning the current Superbonus incentive mechanism, accessible also for the installation of heat pumps. In this context, the paper aims to investigate the effectiveness of the use of air-to-water heat pumps as an alternative to traditional condensing gas boilers in residential buildings, either new or existing. Focusing on single-family houses, different models, differing in building size, envelope characteristics and heating systems were simulated, considering three different climatic zones of Italy. In detail, the energy simulations concerned two main application fields, the former considering the installation of heat pumps in new constructions, characterized by envelopes with high performances, while the latter analysing the use of heat pumps in existing buildings, without intervening on their envelopes with poor performances. The work aims to demonstrate the potential energy and environmental benefits associated with the use of heat pump solutions for space heating and domestic hot water production in both cases. The results allow stressing on the goodness of heat pump technologies in terms of energy savings (expressed in total non-renewable primary energy index) and CO2 emissions reduction, as well as their capability in improving the energy efficiency classes of the analysed buildings, only with system upgrading intervention., CLIMA 2022 conference, 2022: CLIMA 2022 The 14th REHVA HVAC World Congress
