Abstract:
The satisfaction of the household energy demand requires a good knowledge of the consumption from the quantitative and qualitative point of view. Thus, a study of the structure of the demand both in urban and rural environment is necessary,while taking into account the socio-professional category of the subscribers. In urban environment, one distinguishes at first residential housing that the average power does not exceed 1 kVA, afterwards there are residences and villas that the average power is about 3 kVA, and finally luxurious villas with an average Power of 5 kVA. In rural environment, the average power do not exceed 500 W. Thus, the study of the consumption segmentation allows satisfying the energy demand while respecting the constraint of energy saving in the solar field.

Abstract:
A thermal comfort study has been conducted in two towns from two climatic zones in Libya. Some persons were concerned by this survey. They have been asked once each month during one year and the buildings were without air conditioning systems. The study results have been processed and correlations between sensations and globe temperatures have been found. The comfort temperatures calculated PMV/PPD (Predicted Mean Vote / Predicted Percentage of Dissatisfied) for each location. The description of this survey and the methodology of data analysis are described in details in this paper. The main results are discussed and compared with those of similar surveys conducted in different geographic locations and very close to the correlation between comfort temperature and mean outdoor temperature
