Assessment of Ventilation Conditions in Primary Healthcare Centres

Abstract

Adequate ventilation is an essential component of healthy and functional healthcare environments because it contributes to indoor air quality, thermal comfort, infection control, and the overall wellbeing of patients and healthcare workers. Primary healthcare centres accommodate patients, staff, visitors, and caregivers within spaces that may have different ventilation requirements. Inadequate ventilation can result in excessive heat, unpleasant odours, accumulation of pollutants, and increased risks associated with airborne infections. This study assesses ventilation conditions in primary healthcare centres, with emphasis on the adequacy and effectiveness of existing ventilation strategies. The study examines the major factors influencing ventilation performance within primary healthcare facilities. These include window provision, window size and placement, cross-ventilation, room configuration, ceiling height, door arrangement, mechanical ventilation systems, and the relationship between internal spaces and outdoor air movement. Different functional areas, including consultation rooms, waiting areas, treatment rooms, wards, pharmacies, and administrative spaces, are considered based on their varying occupancy levels and ventilation requirements. Particular attention is given to the role of natural ventilation in improving indoor environmental conditions. The availability and positioning of openings can influence the movement and distribution of fresh air within healthcare spaces. Cross-ventilation, appropriate orientation, operable windows, and effective openings can enhance air exchange while reducing dependence on mechanical systems. The study therefore considers how architectural planning and building configuration contribute to maintaining acceptable ventilation conditions within primary healthcare environments. The assessment also considers indoor environmental factors associated with ventilation quality, including temperature, humidity, air movement, perceived freshness, odour, and occupant comfort. High occupancy levels and inadequate air exchange may negatively affect conditions in waiting and treatment spaces, particularly where natural airflow is restricted. The study examines how spatial density, furniture arrangement, building orientation, shading, and surrounding environmental conditions may influence the effectiveness of ventilation strategies. Challenges affecting ventilation performance are also considered, including poorly positioned openings, blocked windows, inadequate maintenance, overcrowding, limited mechanical systems, and modifications to existing healthcare buildings. In addition, climatic conditions and operational practices may influence the effectiveness of ventilation strategies. Understanding these factors is important for identifying practical improvements that can enhance indoor air quality and thermal conditions without compromising privacy, security, infection-control requirements, or the functional operation of healthcare facilities. The study aims to assess ventilation conditions in primary healthcare centres and identify architectural and operational factors influencing ventilation performance. The findings are expected to provide useful information for architects, healthcare planners, facility managers, and public health professionals in improving ventilation conditions within primary healthcare facilities. The study also seeks to support the development of healthier, more comfortable, and environmentally responsive healthcare environments through appropriate ventilation planning and building design.
