Passive solar cooling for hot humid areas represents an important field for innovation, if we want to solve comfort needs in spaces (especially housing) designed to reduce economic, technical and health requirements. In urban areas or deep valleys and rain forests, which are common in most of the tropical equatorial countries, external breeze is not frequent and air speeds are too low to produce cooling, using a simple cross ventilation system. Since 1982 the author has developed new designs and constructions using passive solar techniques. After many field tests, comparative analyses and computer modelling, new combined cross/stack systems , based on overpressured flows and increased thermal flows were improved in order to ensure Internal air speeds, according to the theoretical predictions
Improvements on passive ventilation: a world wide design tool and architectural mechanisms to ensure comfort in equatorial tropical humid areas.
