CNCandy,
Thanks for the interest! The wretched window has always had a sun blind on the outside (except when it blew off, which has happened twice, LOL), and the current one works quite well - having been brought up in a weatherboard house, we always knew that keeping the sun off in the first place was a far better solution than trying to get the heat out after it had got in, LOL.
However the problems with the window also involves radiant heat, glare on winter days, serious haemorrhaging of heat on winter nights, and the standard inefficiencies of aluminium sliders!!
Because the window needs to open (cross ventilation), needs to be either a slider or awning, (because of the short-arm blind, and awning windows don't let much air in), can't have heavy curtains etc on it (it is immediately above the sink and food prep area, and almost above the stove - grease, and fire hazard), and is positioned so far above the ground on the outside, and there is only about 15 cm between the top of the window and the underside of the eaves on the outside, coming up with some do-able solution to both the summer AND winter problems has been difficult.
When I posted before, although I mentioned the winter heat escape problem as well as the summer heat ingress problem, most people seemed to fix upon the heat coming in, not the heat going out!!!
Anyway, I have a green loan approved (sign the paperwork etc next week sometime), and I have now had a builder with impeccable green credentials come and actually LOOK at the whole shebang, as well as some other less difficult but still needy windows, and an insulation issue inside the roof.
The Eligible Items Cert says that one should 'obtain appropriate professional advice before ... undertaking any actions as a result of the information in this report', and we have come up with a solution involving getting the west window double-glazed in a particular manner, and putting a close-fitting roman blind on the inside as well, and we have solutions for the other windows and the insulation stuff too. So when it all happens, it will be All Good, as the kids say.
The Green Loan will pay for all the window stuff, including assorted tinting, stick-on stuff, curtaining and pelmets in various combinations for various other windows. I might be able to justify the insulation stuff too (it was started 2 or 3 years ago, WAY before the current insulation stuff-up), and also the builder's 'professional consultation' costs. Seeing as my mad EIC tells me to do 2 different things with my hot water service, neither of which are appropriate anyway, and says much non-specific stuff about heating and cooling, (eg 'reduce costs' ... 'reduce requirements') I reckon I could easily argue a case for all this stuff, should I be required to at any stage.
Glad your sun blinds are working - back in the olden days when I used to rent, many of us used to get those el-cheapo bamboo blinds (the wider the slat the better), and hang them outside any sun catcher windows - you could hang them with absolutely minimal 'damage' so the landlord didn't get too upset, and they would last a couple of years at least, so if you moved elsewhere, you could take them with you if they would fit, but it wasn't the end of the world if they didn't, and you left them behind. In fact I still have one on a bungalow at the back of my house. Amazing how much difference keeping the sun off/out in the first place makes, eh!!
Once one owns a house, it is still often necessary to have sunblinds all over the place, but if it's your own house and garden, you can also take a longer view and look to planting shady trees or bushes etc. But where that's not possible or for a quick fix, and for renters, some form of sunblind is essential!
