The experimental data were collected by means of a meteorological station consisting of a data
logger (CR10X, Campbell, Logan, USA) and several sensors for measuring different climatic parameters. The data were measured with a frequency of 60 s, averaged every 15 min and stored in
the data logger. The solar radiation falling on the wall was measured using a pyranometer (model 8-48, Eppley Laboratory, Newport, RI, USA) in the wavelength range 0.3-3 mm. The external
air temperature was measured by an Hygroclip-S3 sensor (Rotronic, Zurich, Switzerland); it was
adequately shielded from solar radiation. The air temperature inside the sealed volume, the temperature of the inner surface of the walls and the temperature of the external plaster exposed to
the solar radiation were measured using thermistors (Tecno.el s.r.l. Formello, Rome, Italy) placed
as in Figure 2.

behind each wall (A), sensor for the surface temperature of the wall on the inner side (B), sensor for
the surface temperature of the external plaster exposed to the solar radiation (C).
