Increasingly, European building designers have used
natural ventilation to control air quality and cool
commercial buildings to conserve energy compared to
mechanical cooling and fan operation. These advanced
natural and hybrid ventilation systems may be adapted to
the North American context, but work is needed including
consideration of the broader diversity of climates. An
approach to the analysis of climate suitability is
presented and applied to a number of North American
climates. The climate suitability method presented
offers an approach to predesign analysis for ventilative
cooling that is climate specific and accounts for the
expected level of internal and solar gains for a
building. The climate suitability analysis also yields
estimates of ventilation rates that are likely to be
needed to achieve either a direct ventilative or night
cooling design strategy.
