As of 2024, significant progress has been made, including the completion of the foundational work for the integrated design platform. The LEGOFIT platform is designed to simplify the process of implementing EPH and PED by providing a comprehensive, user-friendly tool for both professionals and end-users. It enables the exchange of technical and non-technical solutions, supports smart decision-making, and ensures interoperability across various systems. The successful establishment of the LEGOFIT Stakeholders' Community has fostered collaboration among public authorities, technology providers, and other key actors. BIM and Virtual Energy (VE) models for several pilots are nearing completion, while others are still under development. Moving forward, LEGOFIT focuses on ensuring the scalability and replicability of its solutions, training a new generation of multidisciplinary experts, and achieving climate-neutral, energy-efficient buildings across diverse European contexts, with a target completion in 2027.
The LEGOFIT project's greatest technological innovation in achieving a positive energy balance is the LEGOFIT platform, an integrated design platform that blends passive and active technologies utilizing Building Information Modelling (BIM). Thanks to the LEGOFIT platform, the modelling of high performance and cost effective active and passive technologies, the LEGOFIT marketplace offers to the users an extensive range of commercially available solutions, specifically chosen by the LEGOFIT technical experts. This platform provides smooth information sharing and system compatibility, giving users simple access to technical and non-technical solutions for improving building energy efficiency. By providing decision-support tools, the platform reduces the pre-construction process and ensures a smoother transition through each project phase. Furthermore, the platform's agile development methodology enables constant contact with stakeholders, allowing for incremental solution enhancements. Additionally, the use of Urban-Scale Model Integrated Digital Twins (USEM-DTs) ensures scalability and the ability to simulate potential energy outcomes at a district level, supporting the development of Positive Energy Districts (PEDs). This combination of advanced tools and smart management solutions has been critical in optimizing energy performance and driving the transition to energy-positive buildings and districts.
