X&Aid

pattern
The unit conducts in-situ experimental research, including in collaboration with other universities and research institutions, as well as technical and scientific consultancy. Its activities integrate the assessment of environmental conditions in indoor spaces (air quality and thermal comfort), the diagnosis of the causes of inadequate conditions, and the design of corrective solutions involving the building envelope, HVAC terminal units and systems, including the implementation of mechanical ventilation with heat recovery (MVHR) systems. The unit is equipped with instruments for both instantaneous measurements and long-term monitoring of indoor and outdoor environmental parameters, as well as the performance of building envelopes and ventilation systems. The research team has an interdisciplinary profile, combining expertise in Building and Environmental Physics, Building Technology, and General and Applied Hygiene.
