I've been around NYC offices for half a lifetime and saw Aralia only once :). they are super slow and hence VERY expensive to get. it's mostly Drac's and sansi - just sitting there with barely any growth. They don't really aim to grow them, just a décor - the least it changes (grows) the better: no need to do anything.
you can't compare office conditions with home: offices are usually at a very steady 68F with fluorescent lighting. don't know for sure about humidity, but some people have 10%, especially up north in z5 and they often lower the night temps to like 55F. that's why I mentioned the chill. and my windows are super duper modern and still when it's 10F outside I get a lot of heat loss off them, but I do have 25' of glass top to bottom :).
the temp is at least 5F lower next to glass vs middle of the room. and that's a now mild z7 for NYC. he has 5hours of light in winter? that's WAY up north and MUCH colder!
lot's of people save on heating bills. Keeping Aralia moist below 65F would lead to root rot in no time. and even if it's kept dryer it won't like it in any case, will drop leaves for sure.
