The work package Impact simulation for climate scenarios, energy performance, and comfort focuses on assessing how climate change affects buildings today and in the future across the project’s living labs. Its main goal is to evaluate energy demand, comfort, and performance under present and projected climate conditions, supporting the transition to Positive Energy Districts (PEDs). Energy efficiency is a key prerequisite for maximising renewable energy production and effective energy sharing a district level. Within this context, this work package tests and quantifies the impact of energy-efficiency and climate-adaptation measures proposed by WP4, helping to identify how energy demand can be reduced and how climate change impacts can be mitigated.
Current activities have focused on producing high-quality weather files that reflect both current and future climate conditions, including extreme events such as heat waves. These files are based on long-term historical data and corrected for urban conditions where needed, and they now serve as the foundation for building simulations across all living labs. Simulation guidelines are being finalised to ensure a consistent approach as each site carries out its own analyses. The expected outcome is a clear, quantified understanding of how different measures perform, enabling informed prioritisation of the most effective solutions for each building. Despite challenges related to data availability and bias correction for the living lab in Terrassa, local expertise has played a significant role in overcoming these issues and ensuring robust results.
