Having already discussed about the improvements to apply in order to reduce the heating energy need, in the case of Jerusalem we concentrate on the summer season, which characterises the most critical situation.
The constant temperature of the ground can, in this tropical band, help keep the temperature low during summer period (fig.1 vs fig.2). However a more effective way is represented by the thermal inertia of some materials, which store heat during the day avoiding overheating and, with an effective ventilation of the indoor ambient, release it during night (fig.9).
