“Research has demonstrated that a number of passive cooling techniques offer considerable potential in reducing demand for fossil fuel energy in the cooling of buildings. The combination of passively driven air movement and evaporative cooling has precedents in the Middle Eastern wind towers and the more recent “Cool Towers” of the Seville Worlds Fair. However, to date, little attention has been placed on the practical application of passive evaporative downdraught cooling (PDEC) to non-domestic buildings. This paper presents a brief ‘state of the art’, and outlines the content of a new three year EC Joule research programme.”
