POSIFIT's Deliverables

WP1 lays the foundations for the POSIFIT deployment by developing a common framework between the consortium partners with the aim of effectively devising the POSIFIT activities on the basis of the political, technical, social and environmental situation of the building sector in the POSIFIT pilot countries. This is a transversal WP aimed at ensuring proper alignment between the POSIFIT operational framework and the single pilot specifications.
● Identifying and systematising virtuous policies and practices, regulatory frameworks, incentive schemes and technological solutions related to the different national contexts in order to effectively contextualise the three key dimensions – regulatory, financial and technical – of energy positive buildings in each partner country (Turkey, Spain, Luxembourg, Hungary and Belgium) (T1.1)
● Building a common activation framework for positive energy buildings on the basis of a comprehensive analysis of the specific barriers and valuable drivers of the POSIFIT countries in order to support the development of an all-in- one design process for new residential constructions and renovations, thus effectively devising the POSIFIT activities
and improving the relevant replication potential (T1.2).
● Defining specific requirements and features for the development and implementation of the POSIFIT digital realm in the form of a technological platform based on a BIM environment that effectively supports the whole design process of positive energy buildings, thus ensuring alignment between the different activities and KPIs (T1.3-T1.4).
● Creating the POSIFIT human realm by establishing a community of key stakeholders of the construction value chain with whom to interact for the successful implementation, testing, validation and replication of the POSIFIT activities (T1.5).

WP2 develops the digital structure that supports the overall residential building design process from deep renovation and new constructions to energy positive houses. POSIFIT’s digital structure is based on a common BIM data environment that is coupled with the digital twins of the pilot sites, hosting the different services of WP3 (POESY, DDC platform, digital building logbook, etc.) and allowing their interoperability. Based on the technical, environmental and financial impacts of modelled technologies on residential buildings, WP2 will provide all the necessary support for the development of the decision-making algorithms for the best set of solutions regarding the different active and passive solutions to be installed in each different case. The WP objectives are the following:
● Collecting specific data from the pilot sites for building characterization, focusing on materials, occupants, energy demand, energy systems, financial data and available information on the sites’ environments (e.g. replication potential, presence of building materials companies, nature based solutions used in the neighbourhood, etc.) (T2.1)
● Developing BIM models of the pilot buildings towards a shared POSIFIT BIM repository (T.2.2)
● Developing digital twins of the pilot buildings and providing specifications for the implementation of BIM-related services (WP3) in the created POSIFIT BIM environment (T2.3)
● Identifying and modeling active/passive technologies and analysing their potential energy, occupant-related, environmental and financial performance, to be used during the decision-making process (T2.4 and T2.5)
● Developing two complimentary algorithmic approaches based on Analytical Hierarchy Process and Machine Learning to define, evaluate and select the best set of solutions to be applied in each pilot case (T2.6)
● Serve as the support base for the digital logbook (T2.1-T2.3, T2.6)

WP3 includes the different BIM-related services that form the overall POSIFIT platform, together with the decision-making algorithm and the digital twins. The POSIFIT platform and its features are integrated in an overarching BIM environment. This is the main pillar of the design process promoted by the project aiming to turn new and existing residential buildings into energy positive structures.. All the BIM-related open solutions for optimal workflow in new constructions and renovation are previous projects’ proof-of-concepts existing platforms and services to be adapted to the POSIFIT decision-making platform. The main objective is to further develop these stand-alone services and make them interoperable under the BIM environment, consistently facilitating their implementation during the entire building life-cycle.
● Evaluating satisfaction and comfort of occupants in the POSIFIT pilot sites, by using a non-intrusive monitoring of the occupants’ behaviour (T3.1)
● Developing a marketplace of solutions which can facilitate and reduce the implementation phase, by providing detailed information regarding the potential impacts of energy efficiency, emissions reduction and financial savings if implemented in the pilot residential buildings (T3.2).
● Creating a performance-based strategy for energy efficiency measures thanks to an existing crowdfunding tool (T3.3).
● Increasing circularity in the construction sector, ensuring end-of-life successful strategies for the materials and components used and applied during construction and renovation phases (T3.4).
● Fostering the scalability of the POSIFIT model thanks to the creation of an open innovation community which provides insight and feedback regarding the POSIFIT design to implementation process and can access the open data regarding the BIM environment and the built digital twins (T3.5).
● Provide suggestions for the modification of the DBL and the creation of a building circularity passport (T3.6)

WP4 focuses on the development of smart energy technologies for the management, control and optimization of the energy assets available in the pilot buildings. Based on the Building Management System (BMS) owned by IES and integrated in the pilot buildings, different optimization and control strategies (e.g. MPC) could be implemented to ensure high performance of the building envelope and technologies. The analysis of the building efficiency over time, together with the lessons learnt in the development of the digital twin during the entire life cycle of the building (WP2) and the related services (WP3) will serve as loop feedback to continuously improve POSIFIT decision making process for improved renovation activities. The WP objectives are the following:
● Developing dedicated BMS for the pilot sites, connected to the digital twins and linked with the BID data environment
● Developing optimization and control algorithms for improving the utilization of the already present and newly installed energy assets
● Improving the platform functions and integrated services over time for better building energy performance and better decision making for implementation of further future renovation actions.

WP5 follows the POSIFIT process from the beginning of the implementation in the pilot sites, the monitoring of the efficacy of the process and the validation of the energy, environmental and financial savings related to the use of the process, additionally considering the social acceptance of the occupants in being involved in the project. It also provides iterative inputs for the improvement of the overall process (T5.2) and for scalability of the POSIFIT concept. The output of WP5 is related to the use of the LEGOFIT process in the pilot sites, its platform and the evaluation of the benefits that the developed methodology will provide to the actors using it. WP5 tasks follow the generalised timeline of the process (use of the POSIFIT platform and list of interventions to be applied, cofinancing methods to finance the interventions, monitoring and evaluation of the results) but, depending on the different lifecycle phases of the pilots, the order can variate. Therefore, the tasks timeline will be defined in T5.1 at the beginning of the project and adapted to each pilot during the project duration.
● When the the platform prototype is available, the pilot sites owners will use it and will receive as an output the list of solutions to be implemented to reach energy positivity (T5.1)
● Data collection and monitoring plan is created and monitoring starts once the passive and active technologies are installed and the control and optimization strategies are set.
● To raise more funding, the co-financing approaches previously studied (T3.3) are implemented on the short term, depending on the required extra funding (T5.3)
● Solutions are evaluated against actual performance and feedback is given to the tool.
● Thanks to urban scale modelling, the potential impact of POSIFIT process at neighbouring scale is evaluated and a set of guidelines for replication and improved certification is created.

WP6 works on spreading the project results and ensuring their exploitation after the project end. Through the interactions with external stakeholders and the general public, POSIFIT will increase its scalability and replicability potential.
Specific attention to scalability, Positive Energy Districts impact and digital building logbook is envisioned. The connection with ongoing legislative proposal at the EU level will ensure the conformity of the project results with the EU long-term objectives for the building sector.
● Formulate an engaging project identity and a long-term C&D plan to ensure engagement of the public audience and the participation in the project activities of external stakeholders (T6.1-T6.5).
● Develop training modules for building operators and professionals to raise awareness regarding the potential of positive energy homes and the use of the POSIFIT platform (T6.4)
● Exploit the different results coming up from the project (e.g. POSIFIT stand-alone BIM-connected services), providing dedicated exploitation plans and intellectual property protection analysis (T6.2 – T6-3)

The project management and coordination encompasses the financial, administrative and contractual components including the risk monitoring and mitigation during POSIFIT. Clear management structures and techniques are in place to build the framework for effortless implementation of the project goals. WP7 is led and implemented by DEM. All partners are involved n the execution of the tasks. DEM will act as a direct contact with the EC. The rest of the partners are involved in the management through the WP and working groups.
