A low-cost Passivhaus in southern Italy was chosen as a sample project to test a compact solution for heating, cooling, DHW and mechanical ventilation. An integrated design approach made possible a cost-effective building. High performances in thermal insulation, airtightness and thermal bridge reduction allowed us to adopt such a simple, efficient and cost-effective solution.
Costs and Finance:
This solution has been compared to a complete traditional solution for MEP in the same region (each apartment has heat pump and radiant floor as heating system, ducted air conditioning as cooling system and also MVHR for each apartment. Our MEP solution is 16,3% cheaper.It made possible to achieve a Passivhaus standard but also an affordable selling price. The apartments are on sale at 1.850,00 euro per sqm, that is exactly the price of all the other apartment in the city for a new construction (even if they are really different for energetic performance and internal comfort).
The compact system consists of a heat pump capable of recovering the extraction airflow heat to transfer it to the renewal airflow and to a DHW tank. In winter conditions, the heat pump is designed in order to partially condensate the refrigerant on the thermal storage tank, so as to dispose the overheating of the refrigerant fluid, and then to complete the condensation on the fresh air flow heat exchanger. The extraction and renewal flows, pass through a recovery heat exchanger with high efficiency, in order to maximize the energy performance of the whole unit.According to the conditioning of the indoor environment, the Compact unit has four modes of operation, automatically managed by the control system, depending on the internal and external conditions of the building: passive heat recovery, active heat recovery, bypass and active cooling.
