I think you are mixing up your units. kW or kilowatts is a figure of power, like my refrigerator, for example, uses 150 watts while its running. If it runs for 11.62 hours out of a 24 hour day like it did last summer when my air conditioner was out of service and my kitchen was over 80 degrees during the day, then it used 1743 watthours or 1.743 kwh per day.

21,359 kWh is likely what you are trying to represent, I see that number as 72,879,898 BTU which is a form of numbers that I'm used to. Oddly enough I've added less heat to my house over the course of the past two years in my house. To qualify in German passivhaus standards, I think you need less than 4,750 BTU per square foot every year. Is this house 15,343 square feet or 1425 square meters. Passive mansion? I'd like to tour one of those.
