Until now investigations of solar climatisation have mainly focussed on office buildings, regarding to the high sensible and especially latent climatisation load during summer time. Nevertheless the market for residential climatisation is also increasing, not only in the USA and southern countries, but also in the European countries, due to higher comfort demands. Thus this study concentrates on the potential of solar climatisation in Single-Family-Houses in different climates.

Passive downdraught evaporative cooling (PDEC)involves spraying controlled volumes of microscopic water droplets into hot, dry ambient air, thereby causing it to cool and descend into a capture zone within a building. From here the cool air enters the adjacent occupied spaces through carefully sized and controlled openings. Close collaboration is needed between architects and engineers for PDEC to work well.

PolySMART is a project partly funded by the European Union where 32 partners have decided to collaborate in order to develop a set of technical solutions for a new market segment for polygeneration, in particular the market for small tri -generation systems. Tri-generation denotes in the present case the combined production of power, heat and cooling in a single system (CHCP). The key components of a CHCP system are the co-generation unit, also called combined heat and power system (CHP), used to produce heat and electricity and the thermally driven chiller used to
convert the CHP heat into useful cooling.
