Infrared thermography measurements are carried out simultaneously. - 1 pressurized test to make it possible to locate the air leakage pathways (with artificial smoke). It enables identifying locations where the thermal losses are potentially important.

The surface temperature values of the double-glazing cannot be interpreted as easily because of the specificity of its thermo-radiative properties. See <03_2012_Paris_01>. The observation of artificial smoke flows confirms the previous considerations by showing the air leakage pathways around areas that should be airtight (window joints). See <03_2012_Paris_02>.

Comfort : The indoor temperature and the hygrometric conditions are measured by a stand-alone sensor. A complete procedure is carried out for these measurements: observations planning (choice of the number of sensors, their type, their locations, the observation period, ), development and setting of the infrastructure (sensor, repeater, datalogger, computer, web application), calibration of the devices, data check system After applying this procedure the sensors are placed in such a way that they will be protected and will not bother the users (see picture 2). All the data collected will be subsequently analysed, for different time scales, in order to evaluate the consumption characteristics according to the indoor comfort conditions.

Observations and measurements on several topics linked to energy efficiency and comfort. Some of these measurements correspond to continuous data from wireless sensors (figure), that s the case for temperature and humidity for example. Electric consumption (continuous) Hygrometric comfort (continuous over limited periods) Acoustic insulation (diagnostic) Air tightness (diagnostic) Thermal losses through thermal bridges (diagnostic) A measurement strategy was defined in order to ensure the comparison of the situations before and after retrofitting. Hence 2 measurements periods were chosen : 1 reference period between January 2012 and autumn 2012, 1 observation period from march 2013 (start of the retrofitting works).

The colder parts of the pictures (see figure 2) indicate locations where the air tightness quality is lower (see figure 1). In figure 3 we observe air leaks from an entrance door from the common hallway, out of the depressurization period, hence the warmer temperature observed for the leaks here. It is important here to take into account the position of the camera (inside/outside) and the direction of the air flows (positive or negative pressures) in order to interpret correctly the measurements. The measurements are made from outside the building aiming at the facade. Warmer parts correspond to thermal bridges, mainly observable for intermediary floors, shear walls, and window frames (see figures 4 and 5). In order to interpret correctly the observations, it is important here to be careful about the diversity of materials included in the field of view, and more especially to the heterogeneity of radiative properties and radiative fluxes conditions.
