Please help.
My standalone BH just completed Plank installation for about 2 weeks but fungus started to grow. The temperature and humidity of each floor of my BH are as follow : at 3:00PM 29/03/11
1st floor 27.3DegC and 99%rh
2nd floor 27.5DegC and 98%rh
3rd floor near roving area 28.2DegC and 88%rh
Data logger data as follow :
1st floor Period from 28/3 20:00 to 29/3 17:00
Temperature 27.5 ~ 28.0DegC
Humidity 93.5%rh ~ 95.0%rh
3rd floor near roving area in the nesting room
Period from 28/3 08:00 to 29/3 17:00
Temperatue 28.5 ~ 29.5DegC
Humidity 81.5%rh ~ 91.0%rh
Obviously the fungus is cause by High humidity.
How can the humidity builded up so high?
I did not use any humidifier in my BH.
My BH is a 22X80X3 storey building.
Each floor I am having total 32 pcs of 3" ventilation holes.
could it be the number of VH not enough?
Please enlighten me.
The fungus problem is obviously caused by high humidity. You will have to determine the source for the water vapour.
