Because presumably in this case you would want to open a window for fresh air, and simultaneously run your heating system to heat up that fresh air?
I was responding to a comment that presupposes the need for fresh air. If you don't need that, feel free to close the windows then.
- TheSpiceIsLife 4y agoAirborne allergens can be an issue, and dust more generally.
- throwawaylinux 4y agoSeems like it would be more efficient to wear a climate controlled bubble suit than heating up entire rooms. And you could even go outside when it is cold or hot or dusty.
- catiopatio 4y agoYou do realize that “open the window and hear that air” is massively energy inefficient, right?
- kccqzy 4y agoI don't know; is it more energy inefficient than having a fresh air intake via a duct? Maybe they are comparable in the absence of a heat recovery ventilation system (mentioned by a sibling comment upthread)?
- mvnuweucxqokii 4y agoYou don't necessarily need to take in fresh air to freshen air in certain ways. It might suffice to pass it though a good filter.
- Zanfa 4y agoHEPA and carbon filters do wonders for cooking smells, particulates etc, but unfortunately do nothing for the main reason you want air exchange with outside, which is CO2 buildup.
- BenjiWiebe 4y agoOur house has a heat exchanger that exchanges air. So the outgoing air changes the temperature of the incoming air.
- Thlom 4y agoYou want to open windows in opposite sides of the house to quickly circulate air from outside to inside. 5 minutes should be enough. It will get colder, but most of the heat is in walls and furnitures and as long as you only open the windows for a few minutes it should be quick to heat up the air again.
