Make-up Air unit diversity: High rise apartment

Make-up Air unit diversity: High rise apartment

Make-up Air unit diversity: High rise apartment

(OP)
I am trying to size a Make-up air unit for a high rise  residential apartment. What diversity would you recommend for the usage?

I have:

166 Bathrooms @100cfm
82  Kitchens @450cfm max, 300cfm med., 150cfm min.

Thanks in advance.

RE: Make-up Air unit diversity: High rise apartment

Typically 85 to 90% of the extract should be supply.

In practice, even if you didn't supply air, the average leaky building would allow the make up air into the building.

The airflow rates you quote are quite high for the UK. We would only require typically 32cfm for WC's or bathrooms and about 130cfm for kitchens without hoods.(we must have small kitchens over here)
