Screen doors/windows disrupting air flow

[Pengwuino]

Where I live, temperatures fluctuate like crazy (I technically live in a desert climate) . We can have 80F degree days and have it drop to 40F degrees that night. My house, for whatever reason, will have the upstairs heat up to the 80 degrees, yet when it gets cooler, it will take a long long time for the temperature to drop to even 76 when outside it has already dropped to something ridiculous like 65.

So I figure hey, open some windows! However, it seems to take a while for the temperature to actually start fall. I mean it definitely falls faster than with them closed but its still oddly slow. Now, the windows have screens on them. So the thing I wonder about is how much the screens are affecting the air flow into my room and other rooms where the windows are open. Does anyone know how much screens can cut down the airflow into a room?

I know I know, I COULD just take the damn things off, but they're a pain in the you know what to put back on. I don't know what kinda moron designed these things.

GAH, What a nerd, I'm not going to read all that...

We have the same problem in our house. Have you considered installing an attic fan? The heat radiating from the ceiling may be overwhelming any cooling that you're getting from the windows.

It's not the screen - it's the size of the windows compared to the volume of the rooms.

Put a fan next to one of the windows and blow the heat out the window. It will increase the air flow into the house at the other windows.

Pengy,

As Borg and Bob stated you need to find a way to vent the trapped heat, blasting a hole in your roof would work, but the collateral damage would be high so, IMHO the next best thing are ceiliing fans or a powerful floor and or window fan. Once you suck the hot air down and push it out, the heavier colder air will eventually fill in. My Mom used to use a swamp cooler in Colorado before she passed away. Keeps the house, nice and dry and in the 70's, cheaper to run (but not to buy) than A/C too. Just an option. They normally mount on the roof.

Rhody...

If you can't or don't want to do a major home project, for windows, you can put in window fans. I actually just prop them in the window in front of the screen.

I use a dual fan like this one. You can have one fan blowing the air out and one pulling the cooler air in at the same time.

My last house had a whole home attic fan. It worked like a charm.

Out of all the ideas you've all have come up with, I like the idea of taking a sledgehammer to two of the walls in my computer room the most. Thanks!

Just make sure it's not two walls that hold up the roof or the second floor!

I think the problem is with the doors, I feel it is not installed in proper location and cross ventilation might be missing.It is very essential to install right kind of doors in right location.You can take the help of experts or search in the internet for experienced people's advise.
