The Effect of External Wall Insulation on Mold and Moisture on the Buildings

In this study, mold and moisture risk of external walls were investigated based on the six different wall types (block bims 1-2-3-4, hollow brick, aerated concrete) three insulation materials (hemp wool, aerogel blanket, extruded polystyrene). During examinations, uninsulated insulated taken into account according to growth depending dew point temperatures. While calculating optimum thickness for wall, degree-day life cycle total cost methods used. The natural gas, coal, electricity accepted as an energy source heating was used cooling. Izmir, Balikesir, Ankara, Kayseri, Erzurum cities selected represent five climate zones Turkish standard (TS 825). As a result calculations, highest values found in hemp wool brick sources. It determined 0.118 m Izmir 0.202 Erzurum. For lowest indoor humidity value, where formation occur, 78% 69%
