Abstract

Until the 1970’s most office buildings in Czech Republic were not equipped with mechanical cooling (air-conditioning). Due to increasing requirements for thermal comfort and warmer summers, nowadays mechanical cooling is often applied to such buildings however without caring for energy consumption. This paper discusses options for incorporating low energy cooling technologies when retrofitting office buildings in central Europe. Climate analysis, design recommendations and role of computer simulation of building and system in the design process are presented. Applicability of night ventilation, evaporative cooling, and cooled ceiling panels, which can provide optimal thermal comfort in a conditioned space in relation to low energy consumption, will be analyzed. The slab cooling using existing slab heating system is stressed in the paper.
