Hello everyone,
The calculated energy demand for one of the houses we are interested in is as follows:
The house is built with Thermoplan S9 bricks, 36.5cm (14 inches) thick, the roof is fully insulated with 30cm (12 inches) of stone wool, and the windows are triple-glazed. I am not aware of any additional insulation measures. Heating is provided by an air-to-water heat pump.
The final energy demand of 17.9 kWh/(m²*a) seems very low to me, given that no additional insulation was applied. Is this achievable with the materials mentioned?

Ultimately, we were convinced by the statement that, when done correctly, external insulation systems (ETICS) are absolutely fine, but there is also a lot that can go wrong. When we started paying more attention, we noticed quite a few houses showing noticeable spotting. At the points where the insulation boards were anchored with dowels, the exterior wall dries more quickly, and over time this leads to color differences due to weathering. This is a common issue. It looks like a failed attempt rather than intentional design. For this reason, it’s better to simply glue the boards on. That way, even after decades, the wall will still appear monolithic.

These 17,x hardly have any significance for your consumption. Also, this is the electricity specification. Why? Of course, consumption depends on the user. With a heating capacity twice as high, the consumption should also be twice as high for the same user. Since 17,x is a relatively low value, you would expect relatively low heating costs, wouldn’t you?
