HIGH AMBIENT AIR-TEMPERATURE FREQUENCY-DISTRIBUTION AT HELLENIC ISLANDS

Energy consumption of buildings for cooling purposes partially depends on outdoor ambient air temperatures. Measured data from eight Helleni c islands in the Ionian and the Aegean sea is used to estimate the fre quency of high temperature exceedance in these islands, useful for est imates of building cooling demand and comfort conditions in the area. The analysis is based on the calculation of the daily T-E value, which is the sum of the daily minimum outdoor temperature and half of the d aily temperature amplitude. This parameter corresponds to a daily aver age value of 9-10 h, during the period of May through September, when the hourly ambient temperature exceeds 26 and/or 28 degrees C in the r egions of interest. The analysis carried out shows that a two-paramete r exponential law, is in excellent agreement with the large values dis tribution for the parameter T-E.
