The GAR Natvent for infection control

Using natural ventilation and other affordable and sustainable means to maximise availability of safe infectious diseases wards and isolation facilities, particularly in low-income settings; bolster health systems; minimise costs and environmental emissions.

    This short film outlines the activities undertaken by the GAR Natvent Design Project which combines building design and infection control for sustainable, low-cost, energy-efficient health-care facilities using natural ventilation.

Natural Ventilation for Infection Control in Health Care Settings

Recognising the role of natural ventilation for infection control, the new WHO guideline provides a design and operation guide for hospital planners, engineers, architects and infection-control personnel.
