Using math tools to improve energy efficiency of courtyards

Using math tools to improve energy efficiency of courtyards | Sustainable Energy | Scoop.it
While some may wonder how our ancestors managed to realize similar solutions in architecture throughout the different cultures around the world, researchers from the University of Seville (Spain) propose that climate played a major role in that process. They also used mathematical tools to reveal the phenomenon that the temperature inside the typical Mediterranean courtyard is cooler than that of the street.

The proposition of architect Juan Manuel Rojas, who developed a mathematical tool able to assess the complex thermodynamic behavior of the courtyard along with two lecturers at the University of Seville, is to use this cooler air inside the courtyard instead using air conditioning extractor units on rooftops or outer walls.

Interesting perspective. But considering 1500 hours of sunshine per year (on a full-load equivalent basis), and assuming no losses in heat storage, one can run such plant at 17% of nameplate capacity during 24 hours (1500/8760 = 17%).
