Short Description

San Polino district is situated on the Est side few kilometers from the center of Brescia City. It is a sustainable district built up with the objective of environmental sustainability and high living comfort.

Consorzio ECO 15 is the operator who built up Comparto 15: it receive the Next Energy Award 2006, in the section “District /System of Building”.
Comparto 15 is crossed by the main road of the district named Corso Bazoli, which is crossed by another principal road –via Levi Sandri. Along via Levi Sandri, there are three buildings, which contains about 82 housings, a nursery school, a toy library and some business units (mainly shops).
Near them, there are 96 detached houses.
Then, along Corso Bazoli, there is the higher and bigger building (corpo E), which counts 191 housings. Here, at the ground floor, there is an auditorium/ theater and some business units.

The main part of the housings is characterized by opening located on the opposite sides of the building.
There is a mechanical ventilation plant which guarantee a good quality of the indoor air with an energy savings (efficiency at least 65%). In spring and summer, when external temperature is more than 17°C, the input fan is stopped and only the extraction one is working.
On the roofs, there are several PV plants-supplied by Brescia Municipality and A2A- for about 200 kWp (overall power).

Key Elements

Air Tightness

External insulation is composed by 8-10 cm of wooden wool, no thermal bridges, both along the vertical walls and on the roof.

Windows and Shading

- Windows are characterized by low tramittances, about 1,9 W/m2K.

- Shading appliance on the South facade to reduce solar insolation during summer but allowing free gains both in spring and summer.

- Openings on opposite sides of the housing to allow natural ventilation

Heating and Hot Water

- No methan gas combustion

- Connection to the distric heating system, with individual exchangers.

- PV plants (about 261 kWp)

- Mechanical ventilation with heat recovery

- Solar plants for warm water production (for detached houses)
