Hello dear community,
Since I have encountered various figures during the planning and consideration of our single-family house, I would like to start a thread where everyone is welcome to share all kinds of information.
Please move the topic if I have posted it in the wrong section.
I’ll start with the house of a good friend:
Type – 1.5 stories, gable roof, basement, approximately 140m² (without basement)
Heating – gas condensing boiler with about 400L (105 gallons) buffer tank and solar panels for hot water (2 panels)
Fireplace – yes, but without water jacket
Ventilation – Systemair VC400
Wall construction
- Eder Thermopor 016 – thermal conductivity Lambda 0.16 W/mK
- Insulation mineral wool rigid boards 120mm (5 inches) WLG035 and lightweight exterior plaster 20mm (0.8 inches)
- Heat transfer coefficient U-value 0.18 W/m²K
Number of occupants – 2 adults and 1 child (2–3 years)
Consumption values (as of 2015):
Water/sewage – 50m³/year (1,765 cubic feet/year) → about €250
Electricity – 2,700 kWh → about €900
Gas – 700m³ (24,740 cubic feet) → about €525 (although the house is heated a bit “too comfortably” for our taste)
Waste disposal, broadcasting fees, property tax… are very region-dependent.
I am grateful for any improvements and tips and look forward to strong feedback.

20 € electricity per month, I would be happy with that, but how do you manage it? I've far exceeded that on my own.It's a complete mystery to me. We manage it in just under a week.......

nordanney14 Mar 2016 16:54Probably due to heating/hot water supplied by district heating, otherwise being away from the apartment and therefore having breakfast and lunch at the office/work, plus regularly eating out. Then coming home in the evening, briefly turning on the TV, rarely doing laundry, and that's about it. A dishwasher is hardly needed or not used at all. No waterbed. What else uses electricity? Oh yes, the medium-sized refrigerator with an annual consumption of 100 kWh.
When I think about everything that is running as standard in our household: a very large refrigerator, a chest freezer, almost daily use of the washing machine and dryer, cooking plus both ovens (necessary for five people), a waterbed, a server, garden lighting, night lights inside the house...
Even an A++++++++ rating doesn't really make much of a difference anymore 😉

Devices that consume a lot of electricity, as far as I remember, are: hair dryers, irons, vacuum cleaners, dryers... Nowadays, laptops, PCs, and TVs, especially plasma screens, probably also count.
Is standby still a relevant issue?
Regarding cooking: one person considers cooking to be heating up a small pan twice for 5–10 minutes, having a pot in constant use, occasionally using the electric kettle, blender, and food processor for 20 seconds, and then baking in the oven at 180°C (356°F) for 45 minutes.
Another person cooks rice and uses it in a salad.

toxicmolotof19 Mar 2016 01:39For a few days now, I’ve been operating my photovoltaic system, which has the nice side effect of allowing me to monitor my household electricity consumption.
The big surprise (although I had somewhat expected it) is the base load. Even when no one is home, there is a constant demand of about 250-300 W, which adds up to 6-7 kWh over 24 hours. That amounts to 2,500 kWh per year, without using cooking appliances, hairdryer, oven, heating, hot water, etc.
Basically, this “only” includes the refrigerator, devices on standby, router, NAS, inverter, heating controller, multiswitch, cable amplifier, modem, and similar equipment.
I was quite surprised by that. The consciously used electricity—such as lighting, washing machine, dryer, dishwasher, oven, cooktop, toaster, hairdryer, Thermomix, and so on—adds roughly another 5 kWh distributed throughout the day (although we mostly use highly efficient appliances).
In addition, hot water accounts for about 3 kWh per day, and depending on the outside temperature, heating adds anywhere from 0 to 8 kWh per day. These values are from before the photovoltaic system was installed.
