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).
