Abstract
This is a study on energy savings by applying and controlling thermal window shutters in a Mediterranean climate. The study starts with a historical flashback on windows in architecture. After examining the factors that affect their thermal performance, technologies and applications aiming to its improvement will be presented. The dissertation then proceeds to the experimental part of the study. This has a simulation part and a real case experiment. On the first part two basic structures of south facing thermal shutters are assessed for the Mediterranean climate: the planar thermal shutter and the louvered thermal shutter. Several materials and control strategies are tested. On the second part, that is actually supportive of the first part, different shutters' control strategies are tested in a real case residential building on the south of Greece. The best construction was proved to be the aluminium insulating louvered shutters that gave a final total energy load reduction of 23.5%. The results were impressive for the cooling load reduction that was 45%. The max profitable investment for these shutters would be 81.0 /m2 (£ 55.0). However the simple wooden shutters also gave a satisfactory load reduction of 14% where 33.5 % was due to cooling load. The max profitable investment for these shutters would now be 38.5 /m2 (£ 26.12). Parameters are then examined that influence loads and profits as window-to-floor ratio, orientation and glazing type. East and west windows shutters were proved a much more profitable investment whereas only single glazing gave a satisfying payback period. The real case experiment showed that when shutters were used during the day the interior temperature was reduced roughly by 2'C when temperatures picked in the mid-day. When applying aluminium foil on the same shutters the results showed that the temperature was further reduced.
