Are you sure about that? A river delta could be completely lush without any precipitation, but I don’t think that’d be a desert.

From the link someone else already provided: Most polar deserts are covered in ice sheets, ice fields, or ice caps. (I'm getting a chuckle out of the multiple layers of pedantry here.)

No reason a ventilation fan can't be installed - that's standard on modern air-conditioned and insulated houses (a "whole-house fan") precisely in order to rotate the air.

Yes, but ventilating the house itself plus the surrounding greenhouse is much more expensive than just ventilating the house itself. Reason being that the volume of air is much larger.

I'm not an expert, but all greenhouses I've personally seen have natural ventilation with vents high up (such as at the peak of the roof) and near the ground.

The greenhouse effect makes the air inside a lot warmer than outside. This reduces its density, and it becomes buoyant and spills out the roof vent.

There may also be fans, but you can get some ventilation for free (energy-wise).

They have little precipitation. There's plenty of ice in the Antarctic.

Nile delta is in a desert (4-8" rain/yr), so yes.

How does a house get fresh air?

In the Nordics, houses (that aren't very old) don't get new air through windows; the air exchange is through a central ventilation system in and out, and modern houses have a heat exchanger to collect the heat from outgoing air and transfer it to incoming air. (The need to cool down residential houses is extremely rare). At least in Finland, newish office houses typically don't even have windows that can be opened; t…

This house was the subject of a Kirsten Dirksen video in 2015: https://youtube.com/watch?v=30ghnDOFbNQ

I can't recommend Kirsten Dirksen's channel enough to people interested in architecture, energy efficiency, tiny homes, 'green' construction, etc. Literally hundreds of hours of high-quality content - I'm really curious how she is able to find all of these interesting people who are doing such cool things. Channel: https://www.youtube.com/channel/UCDsElQQt_gCZ9LgnW-7v-cQ Some other favorites: Baubotanik shapes living…

I want to take two tesla motors, which according to the tesla tear-down, cost $750 each, then take (2) battery packs - place these into the base as a powertrain to a 20’ unit(s) stacked two tall, such that you have a two-story “tiny-home” which can be moved with ease...

Make it draped with solars which can be pushed out as A-frame or other configs.

And all of this can be done for This is my goal.

> At least in Finland, newish office houses typically don't even have windows that can be opened.

That's because the costs for heating of the building during winter are way cheaper than a better thermal isolation of windows and a good ventilation system combined.
