systems update
or
these walls come fully loaded
for the past couple of months we have been focusing on finishing up all the systems so that we can (finally) close the walls. basically that work is now finished though finding the right person to do the heating took a while: we are not only replacing the 50 year old boiler, we are changing from a forced air system to hot water heat, this work is about to start so i'll leave that discussion to a later post.
A/C
we did take advantage of the walls being opened to install central a/c.

the units for the top 2 floors sit on the roof (back & low)

the maze of ducts: amazingly, not visible through the top floor skylights

our a/c contractor has done an incredible job of hiding the duct work.
left: the vent cut into the parlor ceiling (which is in the process of being restored)
(also visible are low voltage cans that we added at the 11th hour feeling that they were necessary to light the walls properly for paintings).
right: the duct that feeds that vent set into the closet floor; there are only two places (here in the closet and at the top of the 3rd floor stairs) where we have to build something to hide the trunks; we were able to do the whole house without dropping any ceilings.

some flexible duct work on the top floor and the unit in the basement for my studio which will have one long round exposed duct down the middle.
ELECTRIC
the electric was a huge job; with only 60 amps coming into the house we definitely need to bring in new service

this requires digging up a portion of the new cement since it is necessary to replace the wooden trough that the electric currently sits in with a metal pipe (seems reasonable). the silver lining here is that we can rethink putting some plantings along the edge of the yard where the cement has been removed.

(left: new meters, right: old)
con ed also wanted to install our new meters on the outside of the building which did not seem reasonable. i would much prefer to let them in to do readings once a month (until the digital read outs become available) than to have 2 meters hanging out in the front.

the electric in the extension wall: my studio will have a combination of lights; florescent fixtures for day to day activity and incandescent fixtures for showing work.
the jury is still out on whether or not to go low voltage here.

some of the massive mess of conduit running through the house
but what a joy to be able to flick a switch and have lights come on!!!
we went with low voltage 3" cans throughout much of the house and find the light to be very pretty.
& a big shout out to joe at lendy electric (137 bowery) for all his help and patience; great service, great prices.

some of the wiring on the parlor floor;

right: preparing for the wall o' appliances in the kitchen
SIDEBAR
in the snap above is a picture hanging on the (soon to be) wall,
it is a rendering of the kitchen;
a little reminder that things won't always be this way

briefly all our appliances will sit on that west wall with the exception of the oven which will be under the island.
on that same wall will be a combination of wood cabinets with horizontal hoppers in glass & metal.
we are foregoing a dining room table and building a large concrete ovoid counter to serve for both prep and dining.
(we are really excited about this so play nice, remember you don't have to live here)
LOW VOLTAGE
or "the information highway starts here"

you might ask, why all this cat 6 in the age of wireless???
i promise you, for some of the work that i do, wireless just doesn't cut it
and again; the walls are open
we still haven't finalized the headache of alarms, intercoms, etc. though i must admit, the prospect of keypads, thermostatic controls, detectors of all sorts, etc. distributed liberally throughout the house in their lovely shades of decorator plastic is beginning to wear rather thin.

What great progress. We're in a similar state and having light switches that actually turn the lights on is a pretty amazing luxury.
Who did you use for your central air?

Great stuff!!
On the A/C: did you consider split-systems like Mr Slim or ArtCool? Mini-ducts? Any insight as to why you went with ducts?
On the Eletric: did you upgrade to 100amps? More? How much did this cost?
Thank you!!

Our house is in the newly created historic district. Do you think we can get away with AC units on the roof?

still sticking with that surfboard island, eh?

watch out where you're drilling through those floor joists. it looks like you are compromising the strength from your photo.

@ all my guests
honestly, the hvac decision was the most difficult one of the whole renovation and we looked at everything.
i personally don't like the split system units, they make me feel like i am in a hotel and we couldn't figure out a way to hide them where we wouldn't "see" them. after much research mini ducts seemed like a good solution if you didn't have the walls open, but since we did (and could duct without disturbing our overall plan) why go that route? from what i understand it's more expensive and you need someone very familiar with the installation procedure or they can be very noisy. on top of that, since the air is pushed through them at a higher velocity they create more of a "blowing air" feeling in a room, which i can't stand (hence the decision to remove the forced air system, but more on that later).
i am not sure what the break out cost of the increased ampage was from the entire electric package (& see faq #8: http://www.brownstoner.com/crownheights_reno/2006/10/post.html#7 )
as far as A/C on the roof in a historic district, my understanding is it's fine if it can't be seen from the street, but you might want to check that.
@ guest 6:27: you are right, those holes should have been in the center and probably spaced a further apart, grrrrrrrrr!
aloha guest 6:17: guess who isn't coming to dinner, ;p

But you apparently do not care about how it looks to anyone who can actually see your roof (but then, who does?) Those massive external ducts make it look like a commercial installation. Eye candy they are not.
My understanding of ductwork is that it should be in conditioned space as far as possible (ie inside, and preferably not even in an attic space); I wonder if your a/c person sold you a bill of goods; there must be a high efficiency hit having the ducts exposed, even if well insulated. Were you concerned about energy efficiency?

honestly i don't think it looks that awful.
For me, the proliferation of satellite dishes (in use and abandoned) and the assortment of dangling wires down fronts of buildings is far more of an eyesore, but to each his own.
you do raise an interesting point re: the ducts being exposed like that and i will bring it up with our a/c contracor, thank you.

Things look worse just after one hits Send.
debated whether to send you this but it's just more information, not sure I agree with all this but who knows. good luck.

1. The roof is a system. The work around the ductwork would only be roof cement which will open in time.
2. They don’t make outdoor ductwork so the A/C guy will cover all the ductwork with roofing cement. If it was that simple to keep water out then you would just do your whole roof with roofing cement.
3. WHEN there is a leak the A/C guy will say it’s a roofing problem and the roofer will say it’s an A/C problem with you stuck with a leak that no one wants to take responsibility for.
4. The A/C unit can feed water from the unit into the house through the ductwork – again who do you call, the roofer or A/C guy.
5. You obviously lose any guarantee on the roof once you do all this.
6. A/C ducts can sweat on humid days. Do you have a roof leak, a duct leak or sweating? Who will take care of it?

honestly, i am out of my league here...
as much as we have tried to educate ourselves, at some point you have to just rely on the people you have hired...
so i'll keep my fingers crossed
and hope this information is good for the next guy.
which, after all,
is what this reno blogging is all about.

Any updates?
I'm waiting w/ baited breath to see how the conversion from forced air (which I also HATE) to hot water heat went and how much it cost etc etc etc....
We are hemming and hawing about starting a similar reno,....I check in w/you to get a reality check and learn...
Keep it coming!
