Passive and low energy cooling techniques in buildings

The paper deals with applicability of passive and low energy cooling technologies in the Czech Republic.There are presented climate, buildings and systems analysis, to find out passive and low energy cooling technologies potential. Some case studies including building simulations and monitoring are introduced (the office building with night ventilation, direct evaporative cooling, slab cooling, role of thermal mass in an historical building, thermal lops). The role of computer simulation in the low energy building design and optimalization is discussed
