SteamyTea Posted October 30 Share Posted October 30 Worth reading though Part F. https://assets.publishing.service.gov.uk/media/61deba42d3bf7f054fcc243d/ADF1.pdf It is not hard, just tedious, like most regulations. 1 Link to comment Share on other sites More sharing options...
Canski Posted October 30 Share Posted October 30 We had our vents measured for LABC at the same time and by the same people that did our air tests. 1 Link to comment Share on other sites More sharing options...

Apparently it’s needed for the building regs ? any ideas Mine were just a simple spreadsheet with individual inlet and outlets based on building regs. If your paying for MVHR design this should be part of the design delivery from contractor. If DIY look at building regs for the gross numbers, plenty of give away spreadsheets on here. Basics are, use Passivhaus as your starter for bedrooms. When you build it near completion, you have the system commissioning done and a certificate is issued, the numbers should match. 1 Link to comment Share on other sites More sharing options...
