The new BH in BM currently is in full operation.
The sound was activated on January 29 th, 2009 and it will be off limit to the owner and myself for three weeks.
The BH was painted with temperature shield paint and we did opened a new hole at the side to allow those birds to use their preferred entrance direction.
The external sound wiring, earlier on, was detected to be wrongly connected. More tweeters were placed on the roof top.
Internal temperature and humidity is within range.
Most of the time when the thermohygrometers were checked the ground floor gives an outstanding temperature range of 29.5*C max and minimum of 26.4*C. The higher floor is slightly higher about 30.2*C max and 27.2*C. I am very comfortable with the range recorded.
As for the humidity, the range is very small. Max 99% while the min was around 97%.
There were no water pots or trays or cans in the BH but the RH seem to be consistent.
Why was it so?
If you have a good look at those pictures taken during the lowest floor construction, my contractor prepared the base with an enclosed bricks structures. When done they poured a sizable amount of river sand. The sand were wet with water initially.
Once the sand were properly laid , leveled and harden , we construct the steel form above it.
The cement were poured to cover the wet sand below. Once level and dried the walls were build around it for the second floor.
The water from this sand reservoir is causing a high room humidity. They seem to be able to seep through the cement floor and filled the BH.
If that continue, it will help to create the high humidity for at least a year or two.
In the meantime I have installed a set of hygrostat attached to a humidifier just in case.
The humidity range was set at 80% min (activate) and 92% max (stop the humidifier).
