Casa sul Parco is a new multifamily building constructed near the City Center Park of Fidenza (Italy). Planned as a high-quality house with Passive House Certification, the builder wanted to offer a complete quality remark and choose the Active House concept to optimize and improve comfort and sustainability.
COMFORT
Natural illumination was particularly important for the project, due to the location in the natural park of Fidenza and as one of the main commercial topics of the object. The different flats were checked by Daylight calculations and improved with the size of the windows. The negative overheating risk is controlled by mobile and fixed shadings and by a cooling unit (geothermal heat pump). Also, the trees around the project were included in the shading concept.
Air quality is handled by the mechanical ventilation system and monitored by CO2 data logging and remote alarm to the constructor.
Thermal comfort is optimized by a certified passive house envelope, which gave the maximum guarantee for winter and summer comfort.
ENERGY
The project started as a certified Passive House construction. The reached goal asked to stay under 15 kWh/m²a for heating and cooling demand. To reach it, the constructor improved air tightness (n50 = 0.58), transmittances (< 0.15 W/m³K), windows (glazing at 0.6 W/m²K), thermal bridges (calculated and reduced), and mechanical ventilation with high heat recovery (84%).
A geothermal heat pump was adopted to raise the use of renewable energy. The heating COP is 4.8, and the cooling COP is 3.8. There are two heat pumps to improve performance for mixed-mode (cooling/hot water production).
Further, the constructor adopted to build a dedicated PV-Plant (prohibited onsite for place protection law), which for validation and certification issues was NOT included in the calculations.
