• 20 cm wall insulation (walls 70% decrease heat loss)
• quadruple glazing (windows 60% decrease heat loss)
• window shade (located at the outer glass inside, isolated heat)
• New air heat recovery (reducing ventilation heat loss 80%)
• CCHP (equal to the cooling and heating without energy)
• HVAC annual energy 90kWh/m2 (9 liters of oil equivalent)
