How is it possible for four people to use only 1800 kWh in the entire house?
I keep wondering how wasteful we must be, as two of us use about twice as much despite having only A+ or better energy-rated appliances and LED lighting, etc.

I keep wondering how wasteful we must be, since with just two of us, we use about twice as much, even though everything is A+ or better and LED lighting, etc...

As I said, I can’t explain it myself either. In the apartment, I still suspected that something might have been wired incorrectly...

In the utility room, there is even a GU10 spotlight with four 50-watt bulbs... I plan to replace those gradually when they burn out. Otherwise, only the two bathrooms and outdoor lighting have LED lamps. The kids’ rooms, bedroom, living area, and hallway use regular halogen bulbs (40 watts with light output comparable to 60 watts). The kitchen has a fixture with four G9 bulbs (one is 30 watts)... but I have already started buying deals and intend to switch those to LED gradually as well. The fridge should only be A+ or AA+ because of the frost-free function. The washing machine is AAA+, but it is used almost daily because we have two kids who get dirty constantly...

I think it comes down to our ONE TV (40 inches, energy efficiency class B), which is typically used only in the evening for about 1.5 hours. Then the heating system also runs for 1.5 hours because of the temperature setting. The PC is connected to this TV, so only one can be used at a time… either computer or TV...

When switching gas providers, I was surprised to see that we consumed over 8,000 kWh of gas from October 14, 2016, to January 14, 2017. The screed drying took place in August and has since been completed, and the consumption from mid-August until October 14 was 3,600 kWh.

About our house:
- Semi-detached house with 180 sqm (1,937 sq ft) of living space, no basement, 3 floors, pitched roof
- Underfloor heating throughout
- Controlled ventilation system with heat recovery
- Gas boiler without solar thermal system
- KfW 70 energy standard, built in 2016
- Household of 3 people
- "Normal" shower and bathing habits, meaning no full baths or bathing multiple times a day
- Rare and short ventilation since the controlled ventilation with heat recovery is running continuously

I find the 8,000 kWh for this period quite high. What do you think?

We have now also received our bill... I think it was about 12,000 kWh for the entire year... the rate was reduced from 100 to 72 euros...

Gas consumption between +5 and +10 degrees Celsius (41 and 50°F) is 3 to 3.5 m³, and at -5 to -10 degrees Celsius (23 to 14°F) about 5 to 5.5 m³ per day... I reported the first meter readings last week:

1635 m³ gas (of which 740 m³ are from screed drying)
2240 kWh electricity (of which 460 kWh construction power)

Moved in on 01/09/2016
140 m² (1507 sq ft) living area
no specific KfW standard
gas heating only

There are more gas heating systems in use than I expected. At the moment, we use 30 m³ (1,059 cubic feet) = 330 kWh per day because the gas heating is running in the drying program.

Heated area is about 185 m² (1,991 sq ft), no KfW, and a roof window is still missing.

Our heating system (district heating) consumed an average of 9.5 kW during the heating-up program over two weeks, which corresponds to 228 kWh per day. What is the efficiency of modern gas boilers? With district heating, it is 100%, meaning the calculated energy is fully delivered as heat inside the house.
