I am thinking Marvin Ultimate clad (wood with aluminum cladding on the outside) but they cost an arm and a leg, even more so with triple glazing to reach R5. Alternatives?

Well, I know a bunch of people (on the oldhouseweb forum, so they do have a point of view!) who would tell you the greenest thing you can do is restore your old window, install good weatherstripping on them, and add really good-quality storms. I believe your house was 1920s? So the wood is old-growth and with care will last for another century or two, and the weatherstripping and storm additions will make it (I've read) nearly as tight as a modern window unit - with the advantage of continuing to be repairable.
I know others here prefer modern technology, but the sight of a bunch of windows (and old doors, and plaster and lath) in a dumpster, and new material coming in, really bothers me. For me it's the history as well as the waste - I'm more traditional Yankee than modern green.
Disappearing back to lurkdom now . . .
