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

It is unclear whether it is related to the house itself. In addition to operating the heating system, there are also behavior-induced factors: Sleeping with the window open cools the room. Leaving windows open during the day on days like today is like switching on a "storage heater." Some of this settles down with handling and new routines.
