MVHR calculator

[Mike]

A couple of years ago I build a spreadsheet for my last MVHR design. I've finally got round to making it more presentable, added some additional checks and - in preparation for a future project - have added a second section so that it calculates using PassivHaus guidelines & English Building Regs in parallel.

 

Since it may be useful there's a copy attached.

Fantastic, and good timing 😃

Nice spreadsheet

 

But it makes designing the MVHR overly complex.
