Abstract

The Q-VENT is a free, online and digital calculator of ventilation rates for residential, commercial and hospital environments. Provides an estimate of the adequacy of these spaces for the recommended air change per hour for the mitigation of SARS-COV-2 virus contagion. An algorithm was developed that provides the professional involved in the design or renovation of the building with a brief assessment of adequation of the spaces for health and mitigation of the contagion by the SARS-COV-2 virus, through: the survey of benchmarks – released by official health agencies and relevant academic works; identification of climatic data related to natural ventilation for 155 Brazilian cities and the identification and adjustments of calculation formulas. The Q-VENT is in the stage of user testing and can be accessed by the public through the World Wide Web on mobile phones or personal computers.
