ᐅ Why is shading especially important in newly constructed houses?

It is often argued that shading is especially important in new builds to prevent overheating in summer. But why is that exactly?
The insulation in a new building works both ways. Whether it’s cold or heat, the house takes much longer to adopt the outside temperature compared to an older house with poorer insulation.
Now, regarding the windows themselves. Shouldn’t solar energy pass through a less effective double-glazed window faster than through a modern triple-glazed window?
Why do many say that shading is PARTICULARLY important in new builds during summer? I would rather think the opposite: a new build is better insulated against heat from outside. Triple-glazed windows with a low U-value keep heat out better than old double-glazed windows.

There is a general subsidy available. At Helios, the individual approval didn’t cost a single cent – it was just unclear at first and a bit annoying due to the waiting time. The service at Helios is excellent and especially fast!
Pressure differential switch = pressure monitor = Why the connection? You can do it that way, but any ordinary pressure monitor simply cuts off the power supply, and that’s enough. I wouldn’t pay much attention to it...
Why your installer doesn’t know about it, I don’t know either – really, the subsidy isn’t exactly advertised.

I assume that the Vallox has the DiBT certification and the Brötje (not yet) does. That might be why he concluded: there is a €1000 subsidy for Vallox but not for Brötje. If I understand you correctly, though, that is incorrect. I should ask him exactly what he meant or had in mind.
However, the contract with the installer was signed a long time ago, and the pipes are already embedded in the basement and ground floor ceilings. From what I can quickly gather, all the subsidy paperwork must have been completed beforehand, so this whole issue is no longer relevant for us.

Night cooling is the activated bypass where heat recovery is turned off. Activating the heat exchanger during the day is sometimes called "passive cooling" or "heat protection." Inside, the air is cooler than outside. When both airflows pass through the heat exchanger, the outside air transfers its energy to the exhaust air. Correct. The heat exchanger does not initially matter which side is warm or cold. Heat always flows from warm to cold.Uwe82 schrieb:
In some cases, warmer air was even expelled outside than was already outside. That happens through the bypass.Bieber0815 schrieb:
Then through the bypass. No, through the heat exchanger. But you’re right, it doesn’t make sense; it was a lapse in reasoning. In this case, it’s more likely a measurement inaccuracy of the sensors.Similar topics
