Objective

Le‟Colaz solution is a groundbreaking response to the current challenges, reimagining construction and renovation as circular, modular, and intelligent processes. At its core, the Le'Colaz framework combines snap-fit modular components, manufactured by bio-based and recycled materials, and digital technologies to create adaptable living ecosystems that evolve with user needs, climate conditions, and regulatory landscapes. The modular components, designed for seamless assembly, disassembly, and reuse, facilitate circular construction practices that reduce waste and resource use.

Le'Colaz integrates two cutting-edge digital systems: the IoM² (Internet of Materials Module) and the IoB² (Internet of Building Brain). The IoM² utilizes sensors and digital product passports to track modular components performance in real time, enabling predictive maintenance and informed decisions on reuse or recycling. This dual function helps extend the useful life of the modular components, thereby prolonging the overall service life of the building. Additionally, it provides valuable information on durability, supporting decisions about whether the products can be reused or have reached their end of life. Complementing this is the Building Brain powered by advanced Large Language Models (LLMs), which combines IoM² data with regulatory and compliance frameworks to recommend renovations, optimize regional reuse of components, and support dynamic adaptations to changing conditions. By connecting multiple buildings into collaborative networks, IoB² fosters smarter, more energy- efficient and adaptable building ecosystems. Central to this framework is a secure database infrastructure designed to store, process, and protect sensitive IoM² and IoB² data.

Equipped with advanced cybersecurity measures, the database ensures data integrity, safeguards against breaches, and stimulates stakeholder confidence in adopting Le‟Colaz solution. This robust architecture also facilitates seamless integration of regulatory data, enabling IoB² to align recommendations with compliance requirements. To validate the framework, Le'Colaz incorporates simulation-based performance assessments during the pilot phase. Dynamic energy modelling tools are employed to simulate various renovation scenarios across building archetypes while real-world data from IoM² sensors is integrated into these simulations to ensure accuracy and relevance to diverse climatic and operational conditions. This simulation-driven approach quantifies the impact of renovations on energy consumption, emissions, and user comfort, ensuring the scalability and effectiveness of Le'Colaz solutions. Living Labs in Athens and Trondheim validate these benefits, demonstrating measurable improvements in energy efficiency, adaptability, and circularity. Le' Colaz creates a framework for modular construction that strengthens innovation while delivering measurable environmental and socio- economic impacts. These include reductions in carbon emissions and material waste, increased resource efficiency, and improved living standards across diverse regions.
