The exposure of the site to the sun is perfect, because there are not high buildings all around that could have projected their shadow on it, but the old building was not able to benefit from this due to the design chosen. The “new” building uses in a smart way all the sun energy that reaches the surfaces of the houses.
The building has been increased to have a higher internal space and a new redistribution of the spaces: this intervention allows to have nine apartments and not only three, reducing the ground consumes.
Rome is placed in the middle of Italy, where we have high temperatures in summer and mild winter. Before the walls were made of not structural concrete because it was a cheap material with a good thermal capacity. Now the walls have being replaced with a compound system of 40cm of thickness, with mineral wool in between two layers of plasterboard, in this way the internal space is protected from the outer environment, so that in winter the heat flows from inside to outside are reduced and vice versa in summer.
