SIMULATED AND MEASURED PERFORMANCE INVESTIGATION OF A BIOCLIMATIC SUMMER RESIDENCE IN GREECE

by PSP. The aim of this study is the analysis of a summer residence in Chalkidiki, Greece, designed and constructed according to bioclimatic principles. For example the effective sun protection in the summer, the natural vertical ventilation, the adequate external thermal insulation ensuring a breathing shell, as well as the usage of high-thermal-mass materials indoors. The result is a natural cool environment in the hot months. State-of-the-art tools (RadTherm) and measurements were used to this end. The main data account for the properties and features of building materials and the local micro-climate. Temperature and wind velocity sensors were placed both inside and outside the building for ten consecutive summer days, in order to verify the simulation results. The results show a satisfactory prediction of the indoor conditions. Subsequently, a scenario, in which ecological building materials, openings, and sun shades were replaced with conventional ones, was simulated. The comparison of the two structures suggested that the bioclimatic design leads to a significant reduction of the indoor temperature up to 6C.
