The environmental concern, ensuring comfort for occupants, pushed us to search for the impact
of glazed loggia on thermal comfort of adjacent space in Cons tantine climate, having s trong climatic cons traints. An experimental s tudy is undertaken and described in this paper. Analysis of the in situ results is also discussed. This work shows that in winter glazed loggia benefit largely from solar gains. In summer, it is a thermal regulating space, delaying diurnal peak of temperature towards the end of the day. Overheating can be avoided with natural ventilation and a good use of the relation glazed loggia-adjacent space. This result leads to the possibility of retrofitting glazed
loggias in hard climates, such as in Constantine (Algeria). To define criteria being able to return this addition, favourable and adapted to the winter and the aestival thermal comfort of adjacent space, a simulation is carried. But the only inves tigation is discussed in this paper.

A few of them know that a balcony behaves like a complementary heat insulation, decreases the losses of heat in the winter and protects the interior of the solar radiation in summer, and that glazed spaces harm the comfort of the occupants and involve a waste of energy, in particular the phenomenon of frequent overheating in summer (Acfas, 2000; Saleh, 2015).

Average air temperature (18,14°C) recorded in the not heated glazed loggia, compared with external average temperature, which was about 10,28°C, does not have any physical significance in the absence of internal gains (Connection between the two spaces is closed), other than thermal inertia.
Comparison of the two livings Indicates that air temperature of the living adjacent to glazed loggia (cell 2) is higher than that recorded in the pilot living with a percentage of time of 89% of the total investigation duration.
The adjacent living space, maintaining the connection with glazed loggia through the open window all the period of investigation, is consequently 8 Table1: Results of the experimental measures relating to the cold season.
