One of the primary European Union’s “Europe 2020” energy strategies is the reduction of the total energy consumption by means of energy efficiency improvements. In the European Union (EU) the building sector is responsible of about the 40% of the total final energy consumption and of the 36% of the Europe global CO2 emissions. During the last decade the European Commission released the first legislative instrument aimed to improve the energy performance of buildings: the “Energy Performance of Building Directive (EPBD) was introduced in 2002 and updated in 2010. The first edition of the document focused the analysis on new buildings, in order to promote the diffusion of energy efficient buildings, characterized by very low energy demand, possibly almost zero energy buildings. The recast of the document introduces the important topic of the existing building stock. It presents and discusses the recommendations that the European Commission released so far and focused on the possibilit...
Renewable Energy Technologies for sustainable Development of Energy Effective Building
IRJET, 2022
The purpose of this study is to identify the most relevant renewable energy technologies for buildings and to assess the effectiveness of their implementation. Methods of analogies and comparisons were used to determine the features of energy efficiency based on the technologies under study. The study proposes the methodological approach to assessing the effectiveness of the introduction of renewable energy technologies. This paper presents a comprehensive literature review on the reactive power management in renewable rich power grids. Reactive power requirements stipulated in different grid codes for REGs are summarized to assess their adequacy for future network requirements. Reactive power coordination between support devices and their optimal capacity are vital for an efficient and stable management of the power grid. The proposed model for assessing the level of energy saving provides an opportunity for economic justification of introducing renewable energy technology in buildings.
Application of renewable energy resources in buildings
Proceedings of the 8th International Conference on Renewable Electrical Power Sources, 2020
The structure of the facilities under construction must be designed to be energy efficient. The contribution of each residential or business, production and storage facility must be viewed in the context of energy savings and transformation through a centralized system. Renewable energy sources (RES) make a significant contribution to energy efficiency in buildings, which can be combined with each other and through huge transformations from thermal to electricity, achieve huge savings. in addition to savings and efficiency, RES also affect the construction of facilities that fit into the living space and compensate for the modalities of heating-cooling-transformation-storage-sale of excess energy The paper analyzes the current state of licensing, design and construction of facilities, as well as the issuance of use permits with reference to the installation of "green" materials and the creation of an appropriate atmosphere that supports renew-able energy sources and energy...
Innovative Hybrid energy systems for heading towards NZEB qualification for existing buildings
This paper deals with the potential role of new hybrid energy systems application along with the heating share concept. It analyses the possibility to develop new plant refurbishment strategy so as to promote the deployment of small scale smart energy systems. Up to now, many new technologies have been implemented can be used for achieving the NZEB objectives. The paper clears up how is possible to share the heat for a small group of dwellings arranged in a single lot. Through the use of a new plant layout for high temperature heat production, it was possible to investigate and compare the results with the typical separated generation systems. Therefore, the new plant design allows the four dwellings to share a cold heat sink able to feed 4 trans-critical CO2 heat pumps. In this way, the four dwellings have been interconnected each other by that hydraulic loop while the electricity is generated by PV arrays and CHP. Outcomes of this comparative analysis has been reported and discussed.

Use of Renewable Energy in Buildings
Renewable Energy - Technologies and Applications
Owing to factors such as high living standards and digitalization, energy use is growing. However, the proportion of renewable energy sources is also rising in all energy consumption. Given this use of renewable energy, global warming and environmental issues are still rising. Fossil-based energy species are more polluting and resource-stricken than others. Studies on environmental pollution show that fossil-based energies are the most important pollutants. Fossil-based energy source is still the most consumed type of energy. Besides, the renewable energy sources’ consumption is very low. Therefore, it is important to increase the use of renewable energy, which creates cleaner and less emissions. Buildings should have the right clean energy use incentives. The needs such as heating, refrigeration, and lighting can be met by renewable energy. This research aims to explore and demonstrate how renewable energy can profit when fulfilling public building functions. Through using both con...
