So it's better to have electrically powered fans that only run when you need
them then ?
I can't understand the logic here - it's certainly cheaper to use vents
that don't need to use power!
As far as "better", that depends on too many variables, like prevailing
winds, average temperature - what I have in mind is, you'll probably need
more ventilation when the winds are calm and the heat is stifling -
convective venting might not be enough, so could use a power assist, but
other than that, I'd invest in one of the passive ones first.
Cheers!
