L shaped area is 45 foot long, 20ft to 40ft wide and 20 ft high ceilings. Very well insulated and sealed since it gets cold in winter in southern new jersey. I had a similar problem I am now finished working through. I'd welcome people's experience / thoughts on this. I would need to sort out some means for a permanent drain though - there are no drains in (or near) the garage. Would I be better off accepting I need to run a dehumidifier? We've got a 4kW solar installation on the house, so assuming some sunshine we'd be using our own electricity during the day which should go some way to offsetting the running costs.
However, I'm now having doubts how much effect this is going to have since I saw a weather forecast the other day showing relative humidity over 80% - simply moving the air is never going to drop the humidity below the ambient outside. I've also got a humidistat I was going to use to control the fan. The fan is rated at 1500 cubic metres per hour, so would 'change' the air in the garage about 6 times an hour. I've bought an extractor fan which I was going to instal in the back wall - there's currently a gap either side of the rsj over the door to allow air in, but otherwise the garage is pretty well sealed (and there's insulation in the ceiling). The garage is 9m long by 7m wide and 4m high, fitted with a roller shutter double door. In spite of this, it's damp! I've been measuring the relative humidity over the last few weeks, and it's regularly between 80 and 90% - which isn't going to do my Caterham or tools any good. It was built on a newly laid concrete floor which had a damp proof membrane fitted. I had a large garage built out of concrete block, built inside a steel Dutch barn.
