Shade via curtains on the outside...

So,would hanging  white curtains on the southern wall of my house be effective shade?
The first story of my house has solid brick walls and no insulation.
I have planted trees, have an opaque fence and I'm considering awnings and growing vines,but I though curtains might be quick, easy and effective.
I would weight them at the bottom,or maybe affix them to a rod on their bottom as well as the tops.
I was  leaning toward using white outdoor curtains for esthetics, but the wife has indicated reflective bubble wrap insulation might be ok!
So, do you think  is this worth  while or  waste of time and resources?

i made a cheap nice awning with tent parts and EMT Conduit really easy to work with and you can make any kind of design with

use shade cloth in the form of a veranda.
It will provide shade, give you space to work in and allow breezes to pass through.
I have used reflective air cell products as well if its very hot, very successfully.

If you are not interested in opening the widows or seeing out, the best things to use is the foam sheets that you get at building supply places.

If you want to open the windows or see out the most effective  is shade cloth added to the screens.

I don't want to cover the windows, ventalatio is too important, and my wife would object,strenuously.
Looking onto the insulation got me looking at coil faced 4x8 boards.
They come with their own "frame"  if you will.
I think I might start with one of these,simply layed against the wall.
I can then check the temperature differences between the shades and unshaded portions of wall.
This might work as part of  an awning as well.

We have used the reflective bubble wrap insulation in the summer with great results. I just safety pin in to our curtains w/ the reflective side facing outward. It keeps the living room w/ large windows cool while getting full sun for the hottest parts of the day. I was able to source it used from work, don't know what the retail price is.

Maybe I'm having one of those moments,  but you wrote that you already planted trees and such... does this mean you are not getting sun on the wall? If you are, at what angle? Is it in the windows? If the sun isn't shining on the house, using shade stuff wouldn't help.  If it is,  then sometimes you need less construction than you may think by just putting a small trellis at the right location/angle.  The benefits of a living cover is the additional evapotranspiration, but if your issue is humidity, then that doesn't matter so much. In that case, a solar fan might be golden.

The trees are growing, slowly.
The sun hits the south and west walls heavily.
I just hacked my grape vines back and redirected them down a cord along the west wall,and a trellis across part of the south.
That trellis has a hardy kiwi as well, but it's still creeping along.
I don't want the grape vines to get up to the second floor where it could damage the cedar shake siding,so I'm keeping it under  8' on the west wall.

So lots of foliage,  but slow going.
Someone in another thread suggested beans will grow quickly to cover a trellis, so that's what my current plan is.
Can't get much cheaper than beans and string...

Ok. Problem solved. I think hops are supposed to grow fast too.  Here's something on passive solar,  in case you have interest. Depending on where you are in the world, a little ledge can go a long way.
