ᐅ Energy Saving Regulation Data (Building Volume, etc.) Are Very High – Why?

Hello,

I have received my calculations for my house, and they seem quite high?!

Building volume Ve = 875
Envelope area = 610
Usable floor area An = 280

My living area is about 230 m² (including balcony, terrace, etc.) (balcony + terrace are about 20 m² (215 sq ft))

The problem is that all the calculators I have used come up with a heating load of around 7. That sounds very high to me for a KfW40+ standard. What do you think?

The actual heated living area is only about 170 m² (1,830 sq ft). Everything else consists of utility rooms in the basement, balcony, etc.

Hello,

No one can assess that accurately from a distance.

It depends on what values you enter into the calculators. For KfW40+, that actually sounds like a lot, but energy saving regulations and KfW standards are rather unusual metrics.

You can try searching on a major search engine for the keywords Crink, Tool, Heating Load. You will find another forum. With a few details (HT value, NAT, building volume, ventilation, average room temperature), you can get a very good estimate there.

You will probably have a warm roof, right? This is included in the heated area.

Yes, I have a hipped roof. Would it make sense to plan for a ceiling on the upper floor?

First, check your data before taking any structural measures!

What is your HT value?
