As construction projects become more complex, traditional planning methods struggle to prevent delays and cost overruns. New research comparing manual and automated 4D BIM scheduling shows how automation dramatically improves speed, accuracy, and consistency by turning static 3D models into reliable time-based plans. The findings present a strong case for automated 4D BIM as a vital tool for efficiency and risk reduction in modern construction.

Europe’s path to rapid decarbonisation depends on transforming its aging, energy-inefficient buildings. New findings from the RINNO Replicability Analysis reveal how advanced, bio-based renovation technologies can be scaled across thousands of similar buildings in France, Denmark, Greece, and Poland. Using a GIS-enabled tool to identify 9,620 suitable buildings, the study shows that deep renovation can deliver exceptional primary energy and emissions savings surpassing EU targets under the Optimistic Scenario, while under the Conservative Scenario, only Greece and Poland exceed these targets. These insights give policymakers and local authorities a practical, data-driven roadmap for accelerating large-scale renovation with real impact.

The RINNO project’s optimised renovation roadmap has now been demonstrated across four large-scale pilot sites (3,386 m² each) in diverse European climatic zones. The solutions show that the majority of RINNO technologies function as intended in real buildings, that several IT tools exhibit clear usability and potential benefits, and that the combined renovation framework delivers tangible improvements in energy performance, indoor environmental quality, and user satisfaction. Although full end-to-end deployment of the RINNO Suite was limited by tool development timelines and individual pilot progress, the work completed provides a robust, evidence-based foundation for future deployment and scaling.

Europe’s construction sector generates over a third of the continent’s total waste and remains a major source of energy consumption and emissions. Yet its renovation rate sits at just 1% - far below what is required to meet EU climate goals. A recent review of circular economy strategies shows that meaningful progress depends on systemic change, beginning with design choices that “design out” waste and enable material recovery at a building’s end of life. Approaches such as off-site construction and prefabrication could cut construction and demolition waste by up to 80%, but financial barriers continue to stall adoption. The findings outline a clear policy agenda: simplify regulatory frameworks, introduce stronger financial incentives, and shift focus from new construction to upgrading existing stock. With the right mechanisms in place, Europe can scale deep renovation, reduce its largest waste stream, and build a genuinely circular, climate-aligned construction sector.

A new rule-based approach to 4D BIM scheduling shows that construction planning can be completed up to 90% faster by embedding predefined logic directly into 3D model elements, eliminating the need for thousands of manual links. Tested on the large-scale Nanterre 2 CESI project in France, the semi-automated method cut the traditional two- to three-day linking process down to just a few hours while producing far more consistent, error-resistant schedules. By shifting repetitive tasks to intelligent model rules, project teams can now focus on strategic decision-making, resulting in more reliable bids, reduced on-site risks, and smoother project delivery. These findings provide a strong foundation for industry-wide digital transformation, demonstrating how smarter BIM workflows can accelerate planning, improve resource coordination, and support more sustainable construction practices.
