Using common technical and average economic resources the environmental results achieved by this single family home are significant:
– Energy certification score A (maximum level), heating demand of 10kWh/sqm·a (30% lower than PassivHaus standard), total energy consumption (including kitchen, outlets, etc.) 60 kWh/m²·a (final) and 150 kWh/m²·a (primary), total water consumption of 50 l/person·day (including garden and vegetable garden).
– The house’s interior temperature, without any active heating system, hasn’t dropped below 19ºC.
– Reduction of grey energy (embodied energy) and CO2 emissions in materials.
– Reduction of construction waste generated for use of prefabricated buildings.
