Construction of a 144 sqm bungalow in Fichtenwalde (near Potsdam)

With 6 construction dryers, it was a bit exaggerated from my point of view.

Using 6 construction dryers was, in my opinion, a bit over the top.

Yeah. There is also such a thing as drying too quickly. Keyword shrinkage cracks. Ask the site manager… We didn't have any construction dryers running…

Here are the data for the dryers. If I have read correctly, that would be about 100 KW, so 35 € per day.

You have started a defined heating protocol with the heating program. At some point, the moisture will come out of the screed more slowly and the plaster will also be dry. Then in the mornings 2 and in the evenings 2 construction dryers will still be more than sufficient. At some point, just ventilating twice a day will also be enough. Letting everything continue to run would really be wasted money. Construction dryers also work most effectively at 80% humidity. But discuss this with the general contractor. He will probably insist on this for warranty reasons.

You have started a defined heating protocol with the heating program. At some point, the moisture will come out of the screed more slowly and the plaster will already be dry. Then 2 dehumidifiers in the morning and 2 in the evening will be more than sufficient. Eventually, 2 short ventilations per day will also be enough. Letting everything run continuously would really be wasted money. Dehumidifiers also operate most effectively at 80% humidity. Discuss this with the general contractor.

The screed is supposed to be sanded next week at the latest. This is supposed to ensure even faster drying. I will bring it up. Unfortunately, the drying will take a bit longer because Kneif forgot to add two additives and the construction supervisor unfortunately did not check it. 2,100 kWh have already been used since the beginning.

The screed is supposed to be ground next week at the latest. This is meant to ensure even faster drying. However, I will address it. Unfortunately, the drying will take a bit longer because Kneif forgot to add two additives, and the BU unfortunately did not check it. On the meter, 2,100 kW have already been consumed since the beginning.

You can calculate with 5 kW per liter of water that evaporates (heat of vaporization) and is removed with the construction dryer.
+Heating up the masonry
+Immense heat losses due to the uninsulated roof
