Air Pressure Testing of Commercial Buildings
"build tight - ventilate right"
If your buildings test result is higher than 5 m3/(m2.hr) @ 50 Pa then you are getting penalised and making Part L compliance much more difficult. The minimum standard for air-permeability is 10 m3/(m2.hr) @ 50 Pa HOWEVER in the real world, you will require significantly lower air-permeability targets to achieve a pass when this figure is entered into SBEM. The air-permeability rate used in the 'notional building' is now 5m3/(m2.hr) @ 50 Pa. i.e. if your buildings test result is higher than 5m3/(m2.hr) @ 50 Pa then you are getting penalised.
All buildings over 500m2 internal ground floor area must be air tested. We carry out testing in accordance with ATTMA guidance and in conjunction with Building Control for Part L approval.
Gladwood’s services can include pre test inspections and reports to help the Contractor achieve the pass he requires. This can include:
- Drawing reviews
- Site inspections
- Sample air testing
- Inspection reports to help convey the issues to the ‘trades’ on site
Avoid air testing failures at the end of the job when carpets are down, ceiling grids complete and access is restricted, our pre-testing and inspection service could save you money!
