Requirements: Key performance Indicators, system components and performance targets – Deliverable released

HYBUILD Deliverable 1.3 – Key performance indicators, system components and performance targets – is now available to download.

The report defines a number of significant performance indicators (namely the Key Performance Indicators, KPIs) to be used at different stages of the project to provide means for the measurement and management of the progress towards project goals and evaluate the impact of the HYBUILD solutions, as a function of different cases of application.

Seven KPIs have been agreed within the consortium and they will be quantified throughout the project and compared with the initial objectives :

  • Thermal Energy Storage Density
  • Seasonal Energy Performance
  • Share of renewable and self-consumption
  • Energy savings and CO2 emission savings
  • Compactness
  • Flexibility
  • Return on Investment

Technical and market review codes studies, national and European certification frameworks – Deliverable released

HYBUILD Deliverable 1.2 – Technical and market review codes studies, national and European certification frameworks – is now available to download.

This report provides an analysis of the technical and economic framework in which the HYBUILD technologies will be implemented, in order to pave the way for the business development and the definition of realistic and achievable market applications.

The methodology followed consisted in analysing first the global HYBUILD solutions, and then the single components constituting them. The same approach was adopted also for what concern the analysis of regulations and directives: the European context was first analysed, and then the analysis was further developed for each target country and for each core HYBUILD components. The market analysis was performed mainly at European level and considering heating and cooling demand given the early stage of the project.

Requirements: context of application, building classification, and dynamic uses consideration – Deliverable released

HYBUILD Deliverable 1.1  – Requirements – is now available to download.

The aim of this report is first to characterize a limited number of climates to be taken as reference in the analysis of the HYBUILD solutions, considering the different climatic conditions as well as the different habits and constraints in energy consumptions. The second purpose is to classify and characterize the most representative residential building typologies in Europe, identifying potential candidates for the HYBUILD technologies application.

The building typologies characterization is carried out starting from the analysis of two of the several tools developed in the context of European projects (FP7) related to the building characterization: TABULA/EPISCOPE (EPISCOPE FP7 EU funded Project, 2012-2016) and INSPIRE (INSPIRE FP7 EU funded Project, 2016).

A methodology to assess the technology applicability, define the sizing of the HYBUILD solutions and to assess their performance in given conditions (climates, building typology, user scenarios) is proposed. It allows for evaluating if the HYBUILD technologies can be applied in the different building typologies and climates and under which conditions.

Another objective is to define user scenarios and boundary conditions consistent with the building typologies, serving as input in the energy simulations used to define loads profiles for heating, cooling and DHW. In this way it is possible, given a set of boundary conditions and uses scenarios, to assess the performance in the different climates. Load profile and peak loads for each building and climate are defined to be used in further energy simulations that will be carried out in the upcoming activities of the project to evaluate the HYBUILD system performance.

Boundary conditions refer to the standard internal gains, the infiltration and ventilation of the buildings, the shading elements and the temperature set points to be considered in the simulations, as well as the scheduling for heating and cooling systems. The user scenarios comprehend additional cases of heating and cooling temperature set points, in order to have a wider evaluation of the performance.

Introducing AIT, the Austrian Institute of Technology

HYBUILD is a group of 21 partners from 9 countries. Every month, a new HYBUILD partner is introduced in our Blog section. Today, AIT.

AIT – In a nutshell

The AIT Austrian Institute of Technology, Austria’s largest Research and Technology Organisation with more than 1000 employees, is taking a leading position in the Austrian innovation system.  With its eight Centers, AIT regards itself as a highly specialized research and development partner for industry and concerns itself with the key infrastructure topics of the future.

At the AIT Center for Energy, around 200 employees are developing solutions towards a sustainable energy system of tomorrow. Many years of experience and scientific excellence of the AIT staff, as well as a high-quality laboratory infrastructure and a worldwide innovation network offer companies innovative and applied research services and thus a clear competitive advantage in this future market. The Center for Energy’s thematic portfolio is based on three central systems: Sustainable energy infrastructure, decarbonisation of industrial processes and plants, as well as innovative technologies and solutions for enabling sustainable urban transformation (buildings, cities). The Center for Energy has gained more than 20 years of experience in managing and participating in large-scale national and international R&D projects.


AIT is responsible for the design of the Continental hybrid sub-system. The Continental hybrid sub-system uses a latent storage which is directly integrated into the heat pump cycle to utilize the sensible heat of the hot refrigerant after the compressor for Domestic Hot Water (DHW). AIT will perform system simulations of the hybrid sub-system which will help to design and control the lab-test prototype and the demo prototype. Furthermore, experimental tests of the Continental hybrid sub-system will be carried out in AIT’s laboratories under controlled environmental conditions. Additionally, AIT leads the “Hybrid storage sub-systems” work package of the project.

HYBUILD Internal and external communication strategy – Deliverable released

HYBUILD Deliverable 8.1 – Internal and external communication strategy – is now available to download.

HYBUILD communication activities aim at demonstrating that hybrid energy storage solutions are a key component in providing flexibility and supporting renewable energy integration in the energy system and can efficiently contribute to the decarbonisation of buildings.

The HYBUILD communication strategy identifies, organises and defines the promotion of project objectives and results and as such it is integral to meeting the overall aim of the project.

The main concept which underpins the HYBUILD communication strategy is to exploit the full potential of the large HYBUILD consortium of 21 partners. Most partners already have well- established online and physical communication presence and through that, they can produce a wide communication impact in Europe and / or in their own country, and they can contribute to quickly raise awareness about the HYBUILD project, its objectives, and its outcomes.

HYBUILD Data Management Plan (DMP) – Deliverable released

HYBUILD Deliverable D8.2 – Data Management Plan – is now available to download.

This report is an initial Data Management Plan (DMP) which outlines how data are collected or generated by the HYBUILD project, in terms of how it will be organized, stored, and shared. It specifies which data will be open access and which will be confidential within the consortium, as far as it is possible to do so at this stage.

Open access (OA) is understood as the free, online provision of re-useable scientific information to other users. There are many good reasons to make the data and findings from publically funded research openly available to the research community, the commercial sector and civil society. Much of the data gathered by the project is for the purpose of project management and delivery rather than new knowledge creation; it is therefore likely that much of the data is categorised as confidential (Consortium). However, the project will seek to openly disseminate its research findings, except in cases where there are defined exploitable outcomes, privacy concerns or there will be a high administrative burden for a dataset of limited worth to other users.

The initial HYBUILD DMP highlights that the most significant datasets identified are the Life Cycle Assessment results of the HYBUILD system (Task 5.1) and the energy performance results of the overall system (Task 6.4). It is these data that will validate the impact of the project and the conclusions drawn in scientific publications that arise. It is intended that where possible these data will be made available through open access repositories.
