The R2UTechnologies project marked its presence at the prestigious Healthy Buildings 2025 Conference, held in Reykjavík, Iceland, by showcasing its research on indoor environmental quality in modular construction.

Presented by Professor Marta Almeida, the poster titled “Indoor Air Quality and Ventilation in Modular Housing Units: Field Measurements in the R2UTechnologies Project” highlighted key findings from field campaigns carried out in modular housing prototypes.

The study focused on real-time monitoring of indoor air quality parameters, including CO₂ levels, relative humidity, temperature, and ventilation rates, across different seasons. It aimed to assess the effectiveness of the integrated mechanical ventilation systems and identify opportunities for enhancing indoor comfort and occupant well-being in prefabricated modular environments.

The results demonstrated that, while modular construction enables efficient assembly and standardization, ensuring consistent and adequate ventilation remains essential to meet indoor air quality standards. The research supports the development of design strategies and technical recommendations that improve environmental performance, contributing to healthier living spaces.

This participation reflects the ongoing commitment of the R2UTechnologies initiative to integrate sustainability, comfort, and performance in next-generation prefabricated concrete modular buildings.
