Executive design and construction supervision of the dialysis department

Studio Calia Srl carried out the executive design and construction supervision for the complete renovation of the mechanical and air treatment systems of the Dialysis Department at the San Filippo e Nicola Hospital in Avezzano (AQ), a key healthcare facility serving the entire Marsica area. The intervention aimed to improve indoor environmental quality and the energy efficiency of the building systems, while ensuring high hygienic and safety standards, essential in a department dedicated to vulnerable patients undergoing continuous therapies. The new HVAC and air treatment system was designed according to the latest sustainability and energy-saving criteria, using high-efficiency units and automatic control systems capable of maintaining constant thermo-hygrometric parameters and air purity levels. Airflow rates were defined based on the activities performed, occupancy levels, and room volumes, ensuring adequate air exchange and precise control of cross-contamination between spaces. The department is served by two dedicated air handling units (AHUs): one for the dialysis ward, maintained under slight positive pressure to guarantee maximum hygiene and patient protection, and one for the negative-pressure room, intended for the management of potentially infectious cases, preventing the spread of contaminants to adjacent areas. Particular attention was paid to integrating the new systems with the existing structures, minimizing the impact of the works and ensuring continuity of healthcare activities during the construction phases. Energy recovery systems were also implemented on the exhaust air, contributing to reduced consumption and overall system performance optimization. This intervention represents a significant step in the modernization of hospital infrastructure in the Abruzzo region, improving quality of care and environmental conditions for both staff and patients, in line with the most advanced standards in hospital engineering and energy sustainability.
