SIPs and flat roof community center, is MVHR helpful?

[xboxhaxorz]

I am a volunteer with a non profit, we are building a hostel/ community center, rooms will have about 6 guests, we plan to build capsule style bunk beds to reduce the noise, each bunk room will have a window, ceiling fan and ductless mini split, we will have 2 bathrooms with 2 of each, sink, shower, toilet and they will have windows, we plan to have a max of 15 cats living in the common area, obv that means litter boxes around, but we will prob used the enclosed versions so guests arent looking at poop

 

Common/ social areas will have ceiling fans as well, perhaps ductless mini splits as well

 

It will be located in Rosarito, MX so San Diego climate essentially except its pretty dusty where we are, cars constantly have dust on them if parked on street, and the roof will be flat, plan to build a 3rd floor later which would be for roof fundraising events, yoga, etc;

 

This is how the plan will look https://imgur.com/a/fOyHjfS, we are still making room size adjustments though, we reduced them to around 9 x 9 ft as the bed shape will be this https://imgur.com/PYzr3kR, most hostel guest dont care too much about room size, common areas are more important

The building on the far right is going to be a cage free animal rescue for about 15 dogs

 

We are looking at panel w with concrete on both sides, roof will be panel as well, trying to make it as passive as possible

I have been googling MVHR and pretty much all pics show it with the traditional US style house with triangle roof

There is absolutely no problem with MVHR in a flat-roofed building, just as it can be installed within an apartment with no roof at all. The entire installation is ideally installed within the heated (or cooled) building envelope, so you just need enough height (or other space) to run the ducts.

 

Maybe Google is showing pitched-roof houses as those are the buildings into which it's mostly installed / the owners who would most often choose to install it.

 

In view of the dust, I'd make sure that you have some good-sized pre-filters ahead of the actual MVHR unit, so that it's not necessary to change them too frequently.
