The experimental set up consisted in a test structure of 2m long, 1m high that holds 3 small scale test cells of 0.6m x 0.6m x 0.6m and three air conditioning apparatus to each cell are coupled. Each cell has 4 insulated surfaces (3 walls and the floor), the test window is placed in the frontal wall and on the top surface (ceiling) a test roof is placed. On the back wall there were two rounded holes of 0.1016 m of diameter to connect the air conditioning system. Figure 1 shows a schematic diagram of the experimental set up of the small scale test cells and the air conditioning apparatus.

Figure 2 shows a small scale test cell and its elements. The surface walls and floor were 0.6m x 0.6m built as pine wood-3cm polystyrene-pine wood with a traverse area of 10.8cm2 surrounded by stripes of pine wood of 0.635m of thickness. The interior of each surface wall was painted with opaque black paint and the exterior was insulated with wool glass fiber of 5.08 of thickness.

The glazings were 6mm thicknes and consisted of clear glass, filter glass and reflective glass. Each roof of the three modules has a concrete slab of 2.54 cm of thickness. Table 1 presents the thermal properties of each component of the small scale test cells and Table 2 presents the measured optical properties of the glazings.
