Primary energy consumption in Algeria continues to grow, and this is associated with the growth in sale on conventional air conditioning systems. This was a major impact on electricity demand specially for summer cooling purpose for north and south regions of Algeria. This investigation demonstrates that the combination of passively driven air movement and evaporative cooling through wind tower system can be used with success and fulfil comfort requirements of hotel accommodation under constantine climate.
This paper presents results from the first year of monitoring the performance of a laboratory building in the new 14.000m2 Torrent Research Centre in Ahmedabad, India. The capital and running costs of air conditioning of non-domestic buildings in northern India are very substantial. while building costs (compared with northern Europe) are low. A cooling technique which maximises reliance on the building fabric and minimises reliance on mechanical equipment is therefore likely to be cost effective. Passive Downdraught Evaporative Cooling (PDEC) represents such a technique.
Home energy ratings seem reliable, but are they? We look at the results from one experiment that tries to answer this question for the existing homes market.
