New policies are being promoted worldwide to reduce the energy consumption for space heating and
cooling in the building sector. As a new technology to achieve this objective, phase change material
(PCM) panels were installed in a new type of ventilated facade to reduce the consumption for space
heating and cooling. During winter, the PCM increases the heat storage capacity of the system exposed
to solar radiation, while during summer the system can be used as a cold storage unit or as a night free
cooling device. The potential of the system to provide energy benefits in the heating period has been
demonstrated experimentally under Mediterranean—continental climate conditions, on the other hand,
limited benefits were found during the cooling season. The aim of this study is to determine the potential
and suitability of this system to operate for cooling purposes, under different weather conditions around
the world. In order to accomplish this objective, an own developed numerical model, based on finite
control volume approach, was developed and validated against experimental data. The numerical tool
is also used to improve the design and to select the most appropriate schedule of the system under the
different analysed weather conditions.
