Being a mechanical geek, I would love a glimpse at the mechanical room and any details you could provide. Sounds like a great project. I think I have designed many commercial buildings smaller than this house.

Thanks for educating me on the LEED residential program. Obviously it doesn't make a lot of sense to spend $100k to get certified when those dollars could be much better spent elsewhere (like in the HT???)...
I took a few pictures of the main mechanical room. The electrical is handled by a group of separate dedicated rooms dealing with just that.
The house is equipped with a full blown DDC (Direct Digital Control) made by Alerton:
http://www.alerton.com/Products/BACtalk/default.asp
A good overview of a DDC, especially of the energy efficiency possibilities can be obtained here:
http://www.ddc-online.org/intro/index.aspx
This is what can throttle the A/C down to less than 2 1/2 tons. Every air handler motor is equipped with a 3-phase variable speed drive to precisely match the heating/cooling requirements.
I included a text-only screen shot of a typical air handler that supplies a room or two depending on size. When the programming is complete, they will supply a graphic of each page that looks like this:

The tricky part of the programming will be to have the system look to the basement air first for cooling or heating before triggering a chiller stage or boiler, etc.

Wow! Thanks for the pictures! I am very aroused by those. 
It is simply amazing to see all of this in a residence. This appears to be on par with some of the light to medium duty commercial projects I have seen. Good for you. I would love some systems like that in my house.
Funny you linked DDC Online. The company I work for is the coordinator of most of that information in conjunction with the Iowa Energy Center at Iowa State University. It is a great resource for comparing controls systems, although it is improving everyday.
What sort of delivery process did you use to build this house? Did you follow the old tried and true design-bid-build process? Or was it all negotiated work under a CM?

Thanks for the photos Arnold !
I think a lot of us have never seen the mechanical installation required for such a large project ...

Oh lookie lookie, three Riello R series oil burners. I assume those are all connected to a TecMar controller or something like it? Folks, just so ya know, If it's cold enough for all three to kick in, the minimum GPH oil consumption for all three is 7.8 gallons per hour. If I'm not mistaken the rating for that model burner is 2.6-16 GPH.
This freaking house must be huge. We just did a 3 boiler installation in a Church. All controlled with a TekMar and fired at 7.5 gallons each. The TekMar is a neat device with boiler, inside and outside temperature sensors. When one boiler can't keep up, it fires the second one and so on. It also has the ability to rotate which boiler is the first to fire so that they all get equal running time in a 30 day period.
I don't know if your oil co. is the installer. If not, please make sure the service department fully understands the controls as you're likely to be working out the bugs for a while.

The audio system has now been finalized and ordered.
http://www.hps4000.com/pages/6chxl_.html
The speakers are:
(3) - 545-4 4-WAY SCREEN SPEAKERS
(4) - 545-W.5 1/2 WOOFER MODULES
(6) - SR-70 SURROUND SPEAKERS
(4) - SR70/WM WALL MOUNT SURROUNDS
The amps are:
(4) VX-440-HPS BGW AMPLIFIERS, SPECIAL
The processor John wants to use is a 'real theater' CP-650-DC Dolby Processor (Digital Version). He is working with Dolby to come up with an HDMI interface since it can only accommodate AES digital audio inputs at this time.

What a project!
You said: "The tricky part of the programming will be to have the system look to the basement air first for cooling or heating before triggering a chiller stage or boiler, etc. "
Couldn't the programming be set to run the fans only, drawing from the basement zone, when there is call and if the temperature doesn't move after 10 or 15 minutes then call for cooling or heat?

Basically yes. There are parallel air systems. The normal one recirculates and conditions the local air, and the auxiliary unit draws the air from deep underground and brings it to above ground. Sometimes one is locked out while the other is running, sometimes they are needed in parallel. The tricky part is setting the parameters, i.e. the clearing set points, the clearing offset set points, looking at the basement temperature in relation to the desired upstairs temperature, etc. It's really 'fuzzy logic' that's needed, and it can all be done, it just has to be custom written as this is not a usual DDC application.
What's gives me the greatest kick is the fact that the waste heat from the 7 KW projector arc lamp is directly fed into the HVAC supply system and put to good use! The projector dissipates 40,978 btus/hr (12,000
kW/h)!!!

You probably already have the product to control your heating and A/C system picked out but if you don't take a look at the Andover Controls Continuum product. I am in the commercial security and BMS business and this is our main product line. It has a "plain english" feature that is really the basic programming language that allows you to write your own code to control any device based on whatever parameter you want. It also has the ability to incorporate your security, CCTV, lighting, sprinkler, etc systems into the same front end for a completely integrated system. We do almost all commercial but have done a few very high end homes such as yours. An example of what we have programmed is the owner uses a uniquely coded wireless transmitter to open his entry gate. This then triggers the driveway lights and after a time delay opens the garage door. If it is night time a pathway of low voltage lights are activated in the house to lead from the garage to the main area the owner normally goes to when arriving home. The heating or AC for specific areas is also activated based on this sequence. I have been is the business for 26 years and would be happy to provide any info or suggestions that you may need. No, not trying to sell you anything, a little to far away to do an install in the North East out of Dallas.

I did not see the Thigpen rotary sub on your list. Did you not want to install one or did you not know what it is? In case you don't know, it is a sub that goes from DC to 20 hz. It has been talked about over at AVS in the Ultra forum. Cineramax put one in, but I have not had a demo yet. I have seen his D-box install which was pretty impressive though.

Wow, what a great project! I built a house in Georgetown, Washington D.C. that was somewhere around 20,000 square feet. We installed twenty-four 450' deep geothermal wells to feed twenty-three air-handlers. Six boilers were installed in the underground mechanical room. From my understanding, the boilers would seldom, if ever, be used. I would love to get back into that type of residential work, it was fun with a lot of new and interesting technology.

Just wondering Arnold about the 103 seats. Will that be the actual number and if so what type of seats are you considering ?
Also why did you settle on that number in the first place ?

Just another thought or should I say question about your vintage arcade. Are many of these something that we might remember playing when we were kids ?
Also it might be fun to see a few photos of your favorites...

The actual number is 105 seats (seven rows of 15 seats). The exact seats have not been selected yet, but they will be wide, deep cushion, traditional type theater seats. The number was arrived at by simply filling the space between the side aisles with seats.
Because the theater will host several charitable and/or political fund-raisers each year, I wanted to allow enough seats to accommodate the expected crowd. The plan is to show a short video of the charity or candidate, and then follow up with a live speech from a podium on a platform area just below the screen. This format should work out much better than the typical "stand up while the speech is given" routine that is typically used.
Of course between events the theater will be used for movies, PPV boxing match parties, etc. Having the large number of seats should also be a tremendous help to eliminating echo which can be a problem in such a large envelope.
As I was designing the theater, one of the main considerations was my belief that in not too many years, new Hollywood releases will have a simultaneous PPV day and date release as well. As such, I wanted to replicate the traditional commercial theater visual and sound experience, minus the sticky floors, ringing cell phones, audience commentary, etc.

Did you have no interest in the Thigpen rotary for sub duty?

There are a couple of reasons why such a thing would not be right for this location. First, given the cubic foot volume of the theater, massive amounts of air must be moved. While the "Thigpen is seemingly great for ultra-low frequencies, how much volume can it put out ABOVE 20 HZ? Secondly, and most importantly, such a device might be great for gaming, etc., but my interest is in reproducing the sound track as accurately to the original as possible. Having a sub system that goes to DC is wonderful, but is there any program content that is on the soundtracks that goes down that low? The bass needs to be precisely matched, not only level wise, but also in correct phase and (direction) with the other speakers. Using this would be like putting a propeller on one of a 747's engines.
My take on this thing is that it is a great gimmick (like moving seats), but it is totally inappropriate for this venue.
Write John Allen and ask him what he thinks...
