HIT2GAP Report Summary

Project ID: 680708
Funded under: H2020-EU.

Periodic Reporting for period 1 - HIT2GAP (Highly Innovative building control Tools Tackling the energy performance GAP)

Reporting period: 2015-09-01 to 2017-02-28

Summary of the context and overall objectives of the project

The ‘energy performance gap’ between the design and operation of a building is well documented and common errors across the four phases of construction (design, construction, commissioning and operational phases) can lead to a performance gap that ranges between 150-250% of the original design specification. Systematically addressing these errors and thus reducing the gap between design and performance is the main objective of the HIT2GAP project focusing on the exploitation phase.
HIT2GAP aims at linking enabling technologies and approaches used in the commissioning and operation phases of construction to improve the comparative predictions of the models and simulations that drive design and the actual performance of new and retrofitted buildings.
The approach taken in HIT2GAP is to build an open, plug and play, application-based platform. This approach is seen as the effective strategy to cover user requirements in buildings that by their nature (typology, climate, usage) are widely diverse. Furthermore, it allows the platform to evolve and remain up-to-date with new emerging technologies in order to better assess energy use within a building. Thus, by design, the HIT2GAP platform is modular and interoperable and includes:
-a connectivity module allowing agile data collection from the field level;
-a management brick ensuring a coherent information platform by providing a semantic interoperability (Ontologies) to unify and normalize the data between all the components of the platform.
-several advanced data processing modules based on data mining techniques and energy management approach to interpret data and identify issues or non-optimised functioning, and to deliver recommendations and decision support.
-information display modules targeting different typologies of end-users and needs and presenting key results in a user-friendly manner, tailored for these various audiences.
To evaluate and maximize the impact of the new solution, HIT2GAP will be tested in four pilot sites and will also challenge several business models and target different customer segments such as direct customers (BMS manufacturers, middleware developers and energy related tools providers) and indirect customers (buildings owners, facility managers, ESCos…).

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

During the first 18 months of the project, the activities concerning the requirements and the methodology associated with a clear definition of the added value brought by each module selected in the HIT2GAP tool delivered a set of specifications associated with:
-the whole platform architecture, its main components and the data infrastructure description considering all the domains covered by HIT2GAP,
-new data sources and associated sensors that complement the current data collection from BMS and provide complementary information regarding occupant behaviour and preferences in order to feed the data mining techniques to provide more accurate analysis,
-a set of data processing modules aiming at converting relevant building data into consistent building energy models suitable for different energy management purposes,
-the energy modelling approach that is pursued within the project as well as the integration of these models in the HIT2GAP platform and the way it can benefit in the energy performance gap reduction,
-the user behaviour modelling and its semantic technology to link users’ activities/interactions with the state or response of the building,
-the systematic approach on energy management system that, applying the requirements of the ISO 50001 international standard, creates knowledge and good practices to generate actions for each significant energy use and improvement opportunity,
-the display modules targeting different end-users and displaying the output of the data processing modules.
The results obtained serve as a basis for a relevant positioning of the project regarding the energy performance optimisation during the buildings operational phase and associated needs in Europe.
Moreover the definition of the detailed architecture for HIT2GAP (figure 1) and specifications of the basic services has been provided. The connection mechanism to gather field data and connect to existing BMSs has been defined and existing sensors and systems have been adapted and tested to integrate within HIT2GAP platform through PLAT.One. The data treatment algorithms have been adapted and their performance has been assessed and tested with off-line datasets. The specification of the mechanisms to connect existing simulation and calibration tools to HIT2GAP platform has been defined. The semantic-driven user behaviour module based on an ontology and semantic reasoning has been implemented and tested to enabling energy gap reduction taking into account users behaviour. A prototype of a event-driven user behaviour module has been developed to reduce system inefficiencies produced by users behaviour. 4 visualisation modules have been implemented to address facility and energy managers and occupants needs.
Concerning the 4 demonstration sites of the project, the baseline related with the current energy performance of the buildings has been established in order to be used for the assessment of the HIT2GAP solution impact.
In addition to the technical developments, HIT2GAP has started to effectively implement its communication and dissemination plan through launching different communication channels, developing materials and implementing the first steps of the exploitation roadmap to ensure the market uptake of the solution. Within exploitation activities, 34 exploitable results have been identified and evaluated. Discussions have also started concerning the associated business models and commercial visions to be refined during the next periods.

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)

"The first technical results are gathered in several deliverables that include a large variety of information from different technological fields. Moreover, the end users requirements overview has been established on the basis of a large range of potential users and stakeholders leading to a good coverage of the different contexts associated with operational phase of buildings in Europe.
The project consortium thus established the link between the needs observed on the market and the requirements that will serve as a basis of the technical developments of the project. These requirements allowed the definition of the HIT2GAP tool architecture and components that allow progress beyond the state of the art in providing a new kind of tool answering to the stakeholders needs.
The market analysis conducted in the frame of exploitation activities also confirmed that the HIT2GAP solution, by providing a middleware between the field level and the management level and by aggregating a large range of applications related with energy management optimisation allows progress beyond the state of the art. On each of these technical fields, the developments conducted as part of the project are allowing progress beyond the state of the art.
The inclusion of ontologies use in the core platform is part of this progress and the open nature of the platform as well. This ""open"" nature of the platform constitutes an opportunity to have the HIT2GAP solution becoming a standard because competitive solutions apply this approach.
The inclusion of a specific ontology in the behaviour modelling module is also considered as a progress beyond the state of the art.
