The project is based on Passivhaus Institute standards such as air tightness, high thermal insulation, solar gains and CMV with heat recovery, in order to minimize energy consumptions. The annual heat demand for heating is less than 14 kWh/m2y and is satisfied by an heat pump and solar panels. The electric power is supplied by a photovoltaic panels system.
Consumptions and the gains are under constant monitoring by a Home Automation System in order to study the energy efficiency of the building.
The Indoor Climate is kept comfortable by an automatic regulating of heating/cooling and ventilation systems. The house has undergone Blower Door Test according to Passivhaus standards (n50 < 0.6/h).
4) Passivhaus Marlegno is a house ALWAYS CONNECTED: the internal network allows a constant monitoring of consuption and a better management of facilities, avoiding waste and saving money.
The careful design of details, the brightness of spaces and the high aesthetic quality make Passivhaus Marlegno a healthy and comfortable home to live in.
We also realized a short free publication, named ZERO impact house, based on this case study:
