But if you haven't been present for it, then i can't really speak to that. Systems are made exactlly for this purpose. As i've said, they are more expensive becase of what's involved in getting them where they need to go given the extra constraints....but they do exist. I've said all along that it won't be easy. Let's go through some of these, and remember we're starting from scratch rather than even touching the old steam based system. But here's what it was.....
Were they central systems or not? Yes, it was a large central system.
Splits? No.
Water or refrigerant? Water. The main unit had not been converted in 2000. That's when my cousing actually worked for the company...in the building...that leased space out there. So i've got first hand knowledge of the place. Being interested, i of course asked a milion questions, and saw some things most wouldn't be able to.
District? Yes it was.
Sizes of spaces? Of course that varies.
Load requirements? Varies if you're using any space as a data center, but since the floor plates in the tower section are so similar, you get a basic same load. What varies are the other portions of the district.
Reconfigurable? Not easily. It would be very difficult compared to what you see today. Remember heating includes radiators as well.
Lift requirements?
How was the ventillation handled to meet code - separate system or integrated? The guts of the thing is from the 20's. Remember code is only applied when major renovations are done. Most floors dont even have smoke detectors either. So code requirements aren't something they had to worry about in the past.
Was the same system used in the commercial spaces?
Was the building occupied 24 hours? No
How was the humidity and changing load handled? You can tell that it wasn't handled all that well. The place can become VERY humid inside in the summer and because VERY dry in the winter.
Was the objective installation costs, operating costs, life costs, comfort control? The goal when it was built, is not what the goal today would be. Individualized comfort control wasn't a question. Much like any large system, the basics of the thing was...it's on or it's off. You get AC or you get Heat. Anyone remember their old dorm days?
------
Now if you want to look at these same questions, but from the new re-hab side, you alter some things. No one would want to see window units on the thing. But what you are going to find, especially if it converts to residential, would be the comfort control ability. No one wants to live in a building with the large central contols like it has today. That question starts the whole discussion of what the new system would look like. It DRASTICALLY changes, as i'm sure you know, what you would do. Knowing that you'll have smaller units like that also means that the amount of infrastructure becomes smaller, but more frequent. Remember, you don't have a dropped ceiling to shove a blower in either...ceilings are too low. So they're going in a close like they would for a home unit. The difference, is going to be on the other end.
Whatever....
