Passive cooling

PASCOOL looked for the scientific gaps in passive cooling techniques as well as ways to increase European knowledge about energy conserving systems to cool buildings. Techniques were developed along with tools to aid both designers and researchers in increasing the use of passive cooling in architecture. A key part of the project has been communicating the results extensively around Europe.

PASCOOL combined a set of related research areas. It did not treat passive cooling as an isolated phenomenon, instead it is included with other aspects of building design to provide an overall environmental design strategy. The Experimental Testing subgroup defined and carried out the experimental work on passive cooling in buildings and developed a database holding all the results obtained. The Model Development subgroup gave accurate and validated methods for the evaluation of the performance of several passive cooling techniques and components, for quantifying their impact in buildings. The Climate subgroup developed a method for calculating the air flow characteristics around buildings and compiled an atlas indicating the potential of natural cooling techniques, namely radiative, evaporative and ground cooling. A diagnostic pre-design assessment procedure to integrate the various research activities and a coherent set of design guidelines were created by the Design Guidelines subgroup.

The project implemented a unique European structure on passive cooling systems. The most important scientific topics were identified and through experimentation, those techniques most appropriate for use in buildings were determined. Seven software tools were developed and guidelines on passive cooling techniques were written. One set of these guidelines is appropriate for a scientific audience while another set has been designed for designers and architects. Final reports cover natural ventilation and thermal mass, solar control, thermal comfort, natural cooling techniques and climatic data.
