Bernal, Sandra Engineer, Altaf Chalfoun, Nader From all the alternatives to provide a better in- door environmental quality in the residential  sector in Northwest Mexico and Southwest U.S.; mechanical ventilation systems are the most commonly used source of air exchange and temperature control. Innovation in the technology of ventilation systems often leads to declining use of natural ventilation, although, during selected days of the year, the free movement of airflow can contribute to human health and energy conservation. This study applies a hazard assessment process to a case study, and compares the three most common systems of temperature control and air supply: natural ventilation, evaporative cooling, and air conditioning; to observe and measure accumulations of dust and temperature variation in a single-family household in Midtown Tucson, Arizona. Firstly, this study aims to understand whether the amount and location of dust accumulations throughout a house is correlated to the type of natural ventilation and mechanical systems in operation at that time. Secondly, this study tests how human exposure to dust is diferent depending on the location of the accumulation within the house. Finally, temperature measurements are discussed to reflect upon the effectiveness of diferent types of ventilation systems in operation, to mitigate dust accumulation. De entre las alternativas para proporcionar una adecuada calidad ambiental interior en las viviendas del noroeste de México y suroeste de los Estados Unidos, los sistemas de ventilación mecánica son la fuente más utilizada para proveer aire fresco y control de temperatura. La innovación tecnológica en los sistemas de ventilación a menudo nos conduce a la disminución en el uso de la ventilación natural, aunque, durante selectos días del año, la libre circulación del flujo de aire puede contribuir a la salud humana y la conservación de la energía. Para este estudio se realizó una evaluación de riesgos sanitarios a un estudio de caso donde se comparan los tres sistemas regulación de temperatura por su función como suministro de aire: ventilación natural, refrigeración evaporativa y aire acondicionado, para con ello observar y medir acumulaciones de polvo y variación de temperatura en una vivienda unifamiliar ubicada en Tucson, Arizona. Este estudio tiene como objetivo entender si la cantidad y la ubicación de las acumulaciones de polvo en una casa están correlacionadas con el tipo de ventilación. En segundo término, este estudio prueba cómo la exposición al polvo es diferente en dependencia de la ubicación de la acumulación dentro de la casa. Por último, se re-flexiona acerca de las lecturas de temperatura y su relación con la eficacia de los tipos de sistemas de ventilación para mitigar la acumulación de polvo.
