Let it snow! (PHILADELPHIA)

I was wondering if anyone knew how a snow-melt system works on a skyscraper with glass roof panels, such as Liberty Place in Philadelphia. I do know a systems is used because of the 60 degree slopes. Are coils used? If so, would they be on the outside of the glass exposed to the elements or could they be placed under (inside the structure)? Would it be necessary to channel the melt water away? I have been curious since I see these buildings everyday going to/from work.

Thanks!

I would think that the building's interior heat would melt the snow as it landed, just as snow melts as it hits your car window when the interior is warm. If there is some fancy system, it probably just consists of heated wires like a car's rear window defrost.
