I had awnings installed on the west side of my 1900 Shingle Victorian in 1999 or so. The frame is galvanized pipe with connectors made for this purpose. The fabric is Sunbrella, the state of the art in this application. They are wearing well, just a little wear where the attaching brackets, due to the movement in the wind we get in Michigan.
The temperature difference is amazing. I have central A/C now, but only use if for about 2 - 3 weeks in the summer (Detroit). Before the awnings, the house was a dutch oven, and once warm would not cool down even at nicht.
Lots of insulation helps too. I also planted a Liberty elm to help shade; it is doing a decent job on the first floor, but I need a few more years for it to help the second.
