Good morning everyone,
I wanted to ask what your house’s electricity consumption is at night when everything is quiet and sleeping, so what is running continuously?
We have a newly built house, moved in summer 2019. Our building services include underfloor heating (air-to-water heat pump), controlled mechanical ventilation (runs at full power 3 times a day for 2 hours each, then reduced), a photovoltaic system, and otherwise the usual nighttime appliances (phone charger plugged into USB outlet, e-bikes charging occasionally, 2 TVs on standby, Alexas on standby, etc.).
At night, we have a continuous consumption of about 232W (with ventilation running at reduced power and when the heat pump is not producing). I can see this in the app for the photovoltaic system. From 0:00 to 6:30 a.m. we consume about 2.8 kWh.
How about you?
Best regards

or diffusion-open houses without controlled residential ventilation,Hmm... it seems someone has been completely misled by the seller. The term “diffusion-open houses” is typical baseless marketing jargon. Buildings are either airtight according to current standards or they are leaky—in which case they are considered defective constructions. But the myth of breathable walls has always been around and keeps reappearing everywhere with persistent regularity.

External thermal insulation composite systems (ETICS) in new constructions are questionable anyway, so we plastered clay bricks.Definitely. There are not many houses here with ETICS in this area, but one already shows dark spots on the exterior plaster after 13 months where the exhaust from the mechanical ventilation system is vented. It’s basically the same phenomenon seen in ETICS houses where windows are constantly tilted open. Above those windows, the plaster also turns black all around.

Controlled ventilation exhaust coming outThis issue isn’t caused by controlled ventilation alone; several factors contribute. These are so-called thermal bridges that encourage algae growth. This can happen to a house without external thermal insulation composite systems (ETICS) as well. I can show you plenty of examples. Just pay attention to the horizontal strips at floor junctions.Simply use high-quality plaster with an algicide additive.

Houses are either airtight according to the Clay bricks have a vapor diffusion value, which means vapor-permeable houses have existed for several centuries; this has nothing to do with airtightness.

Simply use high-quality render with algicide. Okay. So the neighbor basically has two problems: construction areas that create thermal bridges/air exhaust right on the exterior wall and low-quality render. Yeah, he’ll be happy when I tell him this.
However, the horizontal stripes only occur if the edge of the concrete slab between the floors isn’t insulated. If you don’t deal with this, you usually don’t know about it.
