Hello everyone,
I found a commercial building in our area (built in 1993) that I want to buy and convert into a residential house.
The building includes:
- two rooms of 11 sq meters (120 sq ft)
- one bathroom of 11 sq meters (120 sq ft)
- and one large room of 65 sq meters (700 sq ft)
The ceiling in this large room is about 6 meters (20 ft) high. A second floor is planned to be added here. The room itself will be divided into a kitchen and living room.
However, the building currently has an energy rating of 403 kWh!!! The real estate agent stated that this high value is due to the large room with high ceilings, where heat basically escapes. According to him, if walls were added, it would be easy to reduce the value to below 100.
Now the question: How or who can determine whether the building is properly insulated and whether this high energy rating really only results from the extremely high ceilings and large room?
Is there a way for me to check this myself? Can I hire someone to inspect this?
Thank you in advance.

403 kWh per year? That’s great! 😉
Seriously, I assume this is per square meter? If you double the square meters, the consumption (per square meter) is halved—unless you renovate the building envelope.
Important: Is it 403 kWh/m² demand or consumption? What was the usage? Maybe you want it warmer in the apartment than in a storage room or similar.

I’m not sure if that is the demand or the consumption 🙄 The building was originally a bank branch.

As far as I know, you won’t be able to reduce the energy consumption by adding more walls... maybe slightly, as the surface area and volume change marginally. I would recommend consulting an energy consultant and reviewing the wall/roof construction.Ok, thanks for the assessment. I will then look for an energy consultant.
