Figure 6: Plans of the “La Masa” school (after 1947): first and second floor.
In the 1990, the school was refurbished and was checked the structural integrity of
building (see Fig.7).
Figure 7: Photography of the school façade in 1990.
The elements that currently make up the envelope of the school building are:
•
foundations: stonework;
•
vertical load-bearing structures: ashlar stone of the Aspra site (near Palermo);
•
horizontal structures: reinforced concrete;
•
roof: a usable flat part and a pitched part (wood trusses and Marseilles tiles);
•
staircase: reinforced concrete;
•
external frames: wood and double-glazed with two kind of opening (shutter or
transom);
•
interior finishing materials: linoleum on the floor surfaces and marble grit
staircase.
Energy performance analysis
In order to assess the energy performance of school building (only heating season), we
use the method described in UNI TS 11300 Italian standard (parts 1 and 2) (UNI TS
11300-1, 2008; UNI TS 11300-2, 2008). The method proposed by this Italian standard is
