Hello,
we have just built a KFW 55 house. Now that the weather is getting colder outside, we notice that the house is cooling down significantly. The temperature in the bedroom in the attic has dropped to 16°C (61°F) (we have not ventilated because we have a ventilation system). The living room on the ground floor is down to just under 19°C (66°F).
I understand that we cannot expect miracles regarding room temperatures. However, these temperatures seem extremely low to me. It was never this cold in our apartment (built in the 1960s).
Is this temperature drop normal?
Thank you very much in advance for your answers.
Best regards

That depends. At night, the temperature has been below 10°C (50°F) for quite some time. If you don’t let the warmth in during the day, the KfW55 house will cool down as well. We have 24.5°C (76°F) in the dining room because the sun warms it up nicely. However, the hallway is noticeably cooler. It’s simply heating season again.
After three days, you can notice indoors that the temperature outside drops below 10 degrees Celsius (50°F) at night.
Don’t hesitate to turn on the heating; KfW 55 doesn’t mean it’s passive house level.
However, I have to say that although our heating system is generally running, it doesn’t kick in during the summer temperatures, and during this transitional period it also doesn’t turn on automatically, even though you already need some warmth. I compensate by turning the thermostat dial up by 2-3 notches, and then the heating activates the next day. Otherwise, our fireplace is very helpful.
