The design and control of buildings with passive downdraught evaporative cooling.

This paper describes part of an EC funded Joule project in which computer simulation has been used to investigate the viability of applying passive downdraught evaporative cooling (PDEC) to non-domestic buildings in hot dry climates. Using analytical techniques, CFO and thermal simulation, the performance-driven anatomy of PDEC buildings has been elucidated and engineering sizing methods have been developed. It is concluded that PDEC should formulate part of an holistic and carefully integrated solution.

Torre Guil environmental educational centre, Murcia, Spain. Proposal for energy saving and demonstration.

The buildings of this Environment Educational Center, designed with innovative energy saving features, minimize the impact on the preexisting environment. Renewable energy concepts have been applied to the building design, and intelligent control of lighting and air-conditioning has been included. Most of the buildings are green roof underground buildings, where domes that allow spans up to 42 m have been designed. Average energy saving is over 70% on heating and cooling demands and 60% in lighting.

Roof design for natural cooling.

A recent European project explored combinations of radiative and evaporative cooling processes involving the roof for application in the Mediterranean region. The paper introduces the experimental applications which were built and tested as part of the project and the design considerations and applicability data derived from simulation models validated with the experimental results
