Dear List,
Q. Can an active vehicle exhaust venting system provide adequate ground-gas protection (CS2) for an under-croft car park? BS8485 allows '4 points' for such a system (Building Regs 2000 compliant), but does not provide and design specs!
Does it matter what sensors are used? (particulates or CH4/CO2) or where they are placed? (in rafters or on floor) I assume particulate/heat sensors have different trigger conditions from those used to monitor ground-gases?
Cheers David E Jackson.
