I've recently seen an aquatic centre specification with separate targets for wet and dry zones. These would need to be tested separately.
This Passive House aquatic centre (St Sidwells Point) in the UK got a fantastic exterior airtightness result.
But it's only exterior airtightness. One thing we see, particularly for Passive House projects, is that project teams care quite a lot about that external envelope number, but with aquatic centres there are many additional concerns. The corrosive environment of the wet areas will affect the integrity of the structure and systems within them. If all they focus on is the exterior, they could get a lot of problems. Did they have a well-detailed separation between wet and dry zones?
@Paul Carling do you know the tester? Could you put me in touch with him?
- Wet bar target 3.0 m3/hr.m2 @ 50 Pa
- Dry bar target 4.0 m3/hr.m2 @ 50 Pa
