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.

Goldi0911111 Mar 2016 23:28Well, I do have some thoughts on this. For example, if I have to invest an extra €10,000 today but can save around €500 per year on heating costs, I would consider it to become a bit more independent in the long run (after 20 years), although no one really knows how electricity or gas prices will develop.
What do you think about solar thermal houses (e.g., FASA AG)? I find the concept very interesting, but it all sounds and reads to me as if it would never pay off.

Now I'll share about the "hardworking and therefore frugal" household. Two people, both employed. All appliances LED and A+(++).
Electricity consumption was 650 kWh in 2015 and 600 kWh in 2014 :-) Do you cook yourselves? Please don't take this as a judgment, just genuine interest to better understand the low consumption.
We, or rather my wife, sometimes use 3–6 kW just for cooking on certain days.

In our forecast (which matches actual consumption almost 100% as far as measurable) we also included 2-3 kWh/day for cooking.
Best regards,
