In the PASCOOL research program, which is part of the European research project Joule II, one task was dedicated to the development of an interactive software that would summarize the result of the Pascool research program and show the applicability of passive cooling in Mediterranean countries. The aim was to encourage designers to make use of passive cooling strategies in existing and new buildings. Therefore, a software called PEM, Pascool Electroninc Metahandbook was created. A selection of buildings from the southern European countries are presented in this software. The buildings had been previously monitored and simulated as a separate task within the Pascool program. In addition, the software contains a climate database and simple predesign tools for dimensioning insulation and solar protection. Version 1.2 of this software was completed in October 1995 and is available on CD-ROM.
