I don't think anyone objects to double glazed windows, merely cheap plastic ones. If people buy Victorian buildings, they should be prepared to make the effort to maintain them to a suitable standard surely?
If only that were the case Dave, I want to install
"Like for Like" sash style double glazed windows, which would cost me at least 3 times the price of the cheap ones (They look and operate just like the Victorian ones) and have been told under no circumstances will I be given permission. (Already installed in the Empire and the Merrion Hotels)
To help bring my heating bill down and make the place habitable during the Winter months the Conservation Department did come up with the recommendation that I install roof insulation in a Cavity Space that does not exist in my building and that I should install secondary double glazing but that was vetoed during my Fire Safety Inspection when the Inspecting Fire Officer said no, I was not to install it, as it would impede egress of the building in an emergency.
With 65% of Buildings in the Conservation Area benefitting from double glazed windows, of one style or another; with or without permission, all I want is a level playing field, lower Winter Fuel Bills and a Habitable home to enjoy instead of having to endure.
