Big houses like skyscarpers ought to be very airtight and warm in winter...are they ? How are they insulated ?

They are supposed to be tight and they are substantially tighter than buildings in the past, in most cases. A lot of the all glass highrise buildings popular in Scandinavia, Canada and the Pacific Northwest wouldn't comply with many US building codes due to the high solar heat gain during the summer. Infiltration is a big factor in heating and cooling. It's pretty common for existing buildings and homes to have tests to identify problem areas. There are a lot of advancements being made w/ respect to control systems, building materials, and equipment that will help buildings be more efficient, but for existing buildings, you have to find out where the problems areas are and then figure out what needs to be done, whether it's insulation, windows, sealing, etc.
