    Roof cooling techniques can help exploit ambient heat sinks selectively so as to contribute further, or more directly, to the cooling of buildings. Two recent European projects have investigated a series of possible applications suited to Mediterranean climates and building typologies, and the results form the basis of a handbook on Roof Cooling Techniques. Following experimental measurements on test cells in Spain, Greece and Israel a dynamic model was developed and applied to parametric studies investigating a range of roof cooling techniques combining radiative and evaporative cooling processes: variants of roof ponds, water-based and air-based radiators. The parametric studies were extended to produce comparative applicability maps and guidelines. These give a measure of likely cooling energy savings compared to air conditioning and likely thermal comfort improvements for free-running residential buildings. The paper will present the main findings and design guidelines produced by the parametric studies.
