I am very grateful to John for his free Small Studio design and am beginning to plan a build based on this design.

I would like to know how HVAC would be best handled in this space. I wanted to use the Daikin Ururu Sarara split air con system but do I need two - one for each room - or can I get away with one in the live room with exhaust in the control room?

Is there a problem in placing the internal air con in the control room i.e. air flow affecting listening as well as the noise of the fan?

Regards
Jim

In general, it is not a good idea to have one room exhausting its stale air into another room, which is what you would have if you only used one unit. It would not save you much either, as you'd still need to build two duct systems with silencer boxes and fans: One system would be to feed the air from one room to the other, and the second system would be to bring the doubly-stale air back again.

I've always wondered about those Ururu units, and where the stale air goes. As far as I understand it, they include a small duct to bring fresh air into the room, but do they also include another duct to remove stale air FROM the room? If not, then where does the stale air go? A studio is, by definition, a hermetically sealed, with two absolutely air-tight seals all around, on all sides. So having a pipe to bring air into the room is pointless unless you also have another equal sized pipe to take air out of the room....

Any thoughts on increasing the size by adding percents?
You can scale up and down, but do be aware that even though the ratio will remain the same, you are still moving all the modes to a different set of frequencies, which might or might not be in a good musical relationship. Of course, if you scale everything by exactly 200%, then that's not a problem, as you just moved it all down by one entire octave... :) (But you do have 16 foot ceilings then!)

Thanks a lot Soundman!

I only have 11.5 feet :) ...but talking about height...I cant seem to find the height measurement in SketchUp. I might be a bad SketchUp practitioner, but I have looked everywhere to try and find out the height of this studio :oops:

Also, where would you put a/c ?

Use the tape measure tool... :)

John doesn't show how he did it in that case, but I would put a small mini-split on the rear wall in each room, then duct the fresh air and stale air out through suitable locations in the existing structure, using silencer boxes. That would have to be designed according to how much isolation you need.

In this design it seems that when the sliding doors are open it would effectively be a single leaf system. If I need most isolation to be to the outside of the studio would I be better off sealing across the two rooms either where the sliding doors end - or at the end where the outer leaf goes? I realize this would create a 3 leaf area when the sliding doors are closed but I don't think I will be able to afford really thick glass sliding doors.

With any room design, if you open one of the doors on a two-leaf wall, then you only have a one-leaf wall. sliding glass doors are no different than any other doors in that respect.

Isolation is a two-way street: it's really hard to isolate a room in only one direction, such that it blocks sound going out but not coming in! So your isolation is always pretty much the same in either direction.

Those things are pretty expensive, for sure! To save money, you can replace those with ordinary hinged swinging doors. You can put smaller panes of glass in those, at strategic locations so you still have some sight lines between rooms.

Thanks so much for all your input here Stuart.

For ventilation I noticed there is a product from Acoustica called Aeropac

see http://www.acoustica.com.au/aeropac.html

Do you think this is a viable option rather than building my own ventilation silencer boxes?

I just received info that the Aeropac ventilation system costs around $700 (Australian dollars)

Here is my picture thread for the Smallstudio.skp I have increased the size by 25% on one of the rooms. I have also amended a bit due to to door/ hall problems and speakerstand issues.

Quick question. Is it necessary to seal the back of the flush mount and side wall units? I have a lot of room behind these structures for fluffy insulation and was wondering if leaving them open would simply leave them broadband?
