During the last few decades, electric vehicles (EVs) have emerged as a promising sustainable alternative to traditional fuel cars. The work presented here is carried out in the context of the Horizon 2020 project MERLON and targets the impact of EVs on electrical grid load profiles, while considering both grid-to-vehicle (G2V) and vehicle-to-grid (V2G) operation modes. Three different charging policies are considered: the uncontrolled charging, which acts as a reference scenario, and two strategies that fall under the umbrella of individual charging policies based on price incentive strategies. Electricity prices along with the EV user preferences are taken into account for both charging (G2V) and discharging (V2G) operations, allowing for more realistic scenarios to be considered.

The study monitored 10 real European buildings to identify comfort enhancement potential and energy saving potential based on changing the behavior of building users. The results show that the office building could have saved up to EUR 2500 in energy during the study period while the healthcare centers could have saved more than EUR 1000. The highest energy saving potential is related to the use of the Heating, Ventilation and Air-Conditioning (HVAC) system. It has also been found out that there is a potential to improve comfort conditions in all the pilot buildings. The highest potential on comfort is identified in the improvement of the luminance conditions. Full article

In this paper, the application of demand-side flexibility to residential users and energy communities is discussed. From the H2020 project HOLISDER, it appears that selected Key Exploitable Results are not commercially interesting on their own as flexibility services but certainly are an add-on by cross-value stacking to regular energy services. For groups of prosumers, such as energy communities, cross-stacking can enlarge the awareness and commitment within the communities and, therefore, play an important role in the uptake of citizen communities as promoted by the EU Green Energy Package.

District heating networks deliver around 13% of the heating energy in the EU, being considered as a key element of the progressive decarbonization of Europe. The H2020 REnewable Low TEmperature District project (RELaTED) seeks to contribute to the energy decarbonization of these infrastructures through the development and demonstration of the following concepts: reduction in network temperature down to 50 °C, integration of renewable energies and waste heat sources with a novel substation concept, and improvement on building-integrated solar thermal systems. The coupling of renewable thermal sources with ultra-low temperature district heating (DH) allows for a bidirectional energy flow, using the DH as both thermal storage in periods of production surplus and a back-up heating source during consumption peaks. The ultra-low temperature enables the integration of a wide range of energy sources such as waste heat from industry. Furthermore, RELaTED also develops concepts concerning district heating-connected reversible heat pump systems that allow to reach adequate thermal levels for domestic hot water as well as the use of the network for district cooling with high performance. These developments will be demonstrated in four locations: Estonia, Serbia, Denmark, and Spain. Full article

On October 29th the workshop corresponding to the mid-term conference of BIM4EEB (Acronym of BIM Based Toolkit for Efficient rEnovation in Buildings, Horizon Project under grant agreement N. 820660 ) project was held during the Sustainable Places 2020 event. The main focus of the workshop was a general introduction of the project combined with vertical insights on the single tools that have been developed or are still in development. BIM4EEB grows from simple consideration: according to a BPIE analysis on EPC data, about 97% of building stock, currently not in A level, must be upgraded to achieve 2030 decarbonization objectives. As the biggest energy consumers, buildings consume about 40% of energy and they are responsible for 36% of CO2—they are strategic in order to reach the set of environmental goals and subjected to renovation and refurbishment during their lifecycle according to a specific schedule. Refurbishment becomes the crucial point of sustainability not only in construction but also in the environment in general for the coming years. The BIM4EEB project focuses on implementing a complete BIM (Building Information Modelling)-based toolkit to be adopted in the renovation of existing residential buildings to make the flow of information efficient, to enhance communication and data transfer decreasing intervention working time while improving building performances, quality, and comfort for inhabitants. The platform that controls all the tools developed for the best performance of renovation is BIMMS (Acronym of Building Information Modelling Management System platform), namely a management system linked to an operational and multifunctional toolkit for different AEC stakeholders, offering tools for increasing the adoption of BIM in renovation businesses based on an interoperable flow of information. During the workshop, six development tools have been explored in addition to the BIM Management System: BIM4EEB Fast Mapping of Buildings Toolkit, BIM4EEB BIMeaser tool, BIM4EEB BIM4Occupants tool, BIM4EEB Auteras tool, BIM4EEB BIMcpd tool, and BIM4EEB BIMPlanner tool Full article

Few small and medium-sized enterprises (SMEs) have undertaken an energy audit to date and even fewer have taken action to implement energy-saving measures. Lack of time, knowledge, and finance, coupled with the low priority that SMEs give to energy management, are the most commonly cited barriers to effective energy management in SMEs. Four projects funded by Horizon 2020 (SPEEDIER, SMEmPower Efficiency, E2DRIVER, and Innoveas) have developed innovative capacity-building programmes designed to eliminate these barriers and encourage SMEs to undertake energy audits and implement the recommended energy efficiency measures. This paper presents an overview of the innovations being tested and suggests a series of policy recommendations that could help to drive uptake of energy audits in SMEs. Full article

The new Circular Economy System requires an innovative approach to the management of information. The FiberEUse IT platform is a solution that enables the exchange of information among stakeholders that works into and across the glass and carbon fibers value chains, from the design to the end of the circle of life. The IT solution supports companies in scouting new potential market applications and search information about companies, manufacturing processes, and objects. Those objects had been defined “circular entities” and can be products, materials, semi-manufactured objects, wastes, among others. The information available for each circular entity is the one which the company itself wants to share and can propose: description, informative details, technical details, processes adopted to create it, consultancy services used, etc. To obtain this necessary variety, the data model had been structured in a polymorphic way; being able to serve different product histories without the ambition to create a common and classic entity relationship schema but thinking by high level object-oriented design.

RESPOND proposes an Artificial Intelligent (AI) system to assist residential consumers that would like to make use of Demand Response (DR) and incorporate it into their energy management systems. The proposed system considers the forecast energy consumption based on the data acquired. This work compares the results obtained by different forecasting methods using the Root Mean Square Error (RMSE) as a measure of the forecast performance. The ARIMA, Linear Regression (LR), Support Vector Regression (SVR) and k-Nearest Neighbors (KNN) models are tested, and it is concluded that the results achieved with the KNN obtain a better fit. In addition to obtaining the lowest RMSE, KNN is the algorithm that spends less time in obtaining the forecasts. Full article

This paper assesses storage applications from an environmental, economic and technical dimension. Three different demonstration set-ups are considered, as well as one large-scale simulation. The results emphasize that storage needs to be tailored to a specific purpose and tradeoffs between the three perspectives have to be considered to benefit the entire energy system. Currently, system integration and the possibility to use the grid as storage are hampering the potential of storage. It is however shown that storage can provide valuable technical and environmental benefits to the grid and possibly defer grid investment. Full article

Given the important role entrepreneurship can play in the energy transition, in this paper we set out to better understand how more radical business models and entrepreneurial journeys are shaped by the institutional context and other system factors within which they aim to scale up. The aim was to explore research questions related to how more radical business models and services, and the entrepreneurs developing them, deal with the system around them, and what the system conditions are that either limit or facilitate the flourishing of those energy services that are potentially strong contributors to the energy transition because they challenge the existing system.

It is important to assess the effectiveness of different energy refurbishment scenarios in the early design stages of apartment buildings. This paper demonstrates the main features of a new tool BIMeaser (BIM Early Stage Energy Scenario - a product of the European Union Horizon 2020 project BIM4EEB), which supports the decision-making process in the early stage of design. The tool uses the BIM and linked data from the BIM Management System (BIMMS) for faster initialisation of the actual state, resulting in more accurate building models. The tool finds solutions in accordance with the client’s requirements while also aiming to minimize energy use and maximize the occupant’s indoor climate comfort. Full article

The nearly Zero Energy building (nZEB) renovation market is currently the key feature in the construction sector. RenoZEB aims to develop a systematic approach for retrofitting by assembling different technologies in a plug and play building envelope. This paper presents the methodology used to transform the RenoZEB concept in the design system. A multi-criteria decision matrix is used for the selection of the best façade technologies within the market while the analysis of the existing building conditions allows to develop a replicable approach for designing deep retrofitting intervention through a plug&play façade. The methodology appears to be a valuable support for the selection of technologies and allows to define a design guideline for the envelope. Full article

Although it has been demonstrated that demand-side flexibility is possible, business application of residential and small tertiary demand response programs has been slow to develop. This paper presents a holistic demand response optimization framework that enables significant energy costs reduction for consumers. Moreover, buildings are introduced as main contributors to balance energy networks. The solution basis consists of a modular interoperability and data management framework that enables open standards-based communication along the demand response value chain. The solution is being validated in four large-scale pilot sites, which have diverse building types, energy systems and energy carriers. Furthermore, they offer diverse climatic conditions, and demographic and cultural characteristics to establish representative results. Full article

Effective and efficient building renovations require significant data management and analysis. The ability to store, analyse, and display this data in a user-friendly way can play an important role in easing the process. The tools developed by authors of this paper during their work in the BIM4EEB research project are contained in three distinct intuitive applications that will allow users to (a) find recommended positions for HVAC, lighting, and other devices; (b) analyse data from sensors, energy bills, and other sources (weather for example); and (c) manage the data that they have on the above and create new data sets that they can share with other tools.
