Short Description
Since 2009, Coop Casa has moved into the new head office wich is situated in Corso Bazoli, 41, in the middle of the new urban sustainable district named Sanpolino.
Coop Casa’s new head office is placed in a multi plan building (named edificio E) and it occupies a 470 m2 surface distributed in three levels: at level 1, there is the reception and the activities related with the dwellers, at level 2 there are both the administrative and the techical offices, at leve 3 there is the meeting room.
Key Elements
Air Tightness
The envelope is composed by wooden light walls and external insulation.
Medium density wood wool (160 kg/m3) is the insulation material: it confers high thermal resistance and good thermal inertia.
Windows and Shading
The windows are characterized by low trasmittance (Uw=1,4 W/m2 K).
The objective is to reduce thermal loads during summer season.
Heating and Hot Water
Heating and cooling are provided by radiant panels disposed in the walls, in the ceiling and in the floor.
Energy for heating is provided by a water-water high efficiency (Coefficient Of Performance-COP more than 4) heat pump which draws heat from ground water. During summer, energy for cooling ids provided by ground water which exchange heat with an exchanger plates (EER more than 9).
Air exchange is guarantee by a mechanical ventilation system with heat recovery (efficiency about 90%): this allows high quality of the indoor air reducing thermal loss due to opening windows for ventilation.
There is a solar thermal plant for the warm water production (about 2,5 m2).
There is also a PV plant (12,47 kWp) which enslaves the head office electric appliance.
Funding
The PV plant enslaves the head office eletric appliance. There is a net metering contract.
Furthermore, it takes the national contribution named Conto Energia, about 0,412 €/kWh for twenty years.
Main Results
Lessons learned
Importance of correct information about plant (expecially mechanical ventilation) use.
