This presentation, titled „Modelling of the hospital indoor environment,” was authored by Kim Hagström. It focuses on healthcare-specific standards and tools for air distribution design. The content highlights that hospital ventilation guidelines often differ from generic standards because they must account for healthcare-specific insights and current practices. A major portion of the presentation compares general room ventilation, which aims for uniform airflow, with „target-specific ventilation” designed to optimize conditions in high-priority zones. It details specific use cases, such as patient rooms and isolation units, where airflow must address varying occupancy and increased infection risks. The presentation also explores target-specific ventilation in operating rooms, emphasizing the need to identify „critical zones” based on different surgical procedures. Technical design tools from Halton, such as eHIT and HIT Design, are showcased as methods for dimensioning diffusers and simulating room air distribution.
