factor
. It is quite inevitable considering that a large part of the country is situated in
the hotter climatic areas (Fig. 5).
The aim of the law is plain: you must take under consideration this problem in the early
steps of the architectonical design and it is not enough to limit your attention to the
control of the heating systems. But the indications of the law are only qualitative and not
binding.
To the European and national framework you must add the regional laws. In particular,
regarding this aim, you have to consider the local building regulation, this entente was
agreed upon by the national & regional Governments and local authorities to stimulate
the renovation of the houses. It was adopted in Sicily by the Regional Parliament: LR
23/3/2010 n. 6. With it you can obtain a prize, a bonus to increase the volume of a
house, considering various items of sustainability in the refurbishment of it. These, called
bio-architectonic items, are grouped in five thematic areas: energy, water, materials,
waste and health … The Filicudian house respects numerous points in the list: regarding
the summer cooling (art. 2, area 1°, point 7), the rain-water recover (art. 2, area 2°, point
1), the usage of local material (art. 2, area 3°, point 2), high acoustic insulation of the
opaque building envelope (art. 2, area 5°, point 3).
So you can also consider the Filicudian house as an
ante-litteram
example of
environmentally friendly building.

Thermotechnical parameters
The indoor living quality of the Filicudian house is so plain to see that any quantitative
measurement should be not necessary. During the hot summer season, you can stay

There you have a list of advice for the designers, to limit the energy consumption of AC usage in the
summer and to minimize the indoor temperature of the rooms. They have to respect the following
criteria, for all categories of buildings: A) they have to evaluate and to document the efficiencies of the
internal or external shading system’s glass surfaces, fitted to reduce the sunlight insulation; B) they
have to verify the average weight of the opaque surface (vertical, horizontal or sloping), which have to
be up to 230 kg/m
2
; C) they have to set the internal conditions and the disposition of the rooms to
promote the natural ventilations of the building (see D. Lgs. 192/2005, annex I, point 9).
