Am I the bird whisperer?

It's really not easy to build an ideal sanctuary for swiftlets in the farmland and I pondered over for weeks just how I can build a better sanctuary if not the best as it can be before the construction job ever started. I've come out the prototype of my swiftlets sanctuary and put it to work just recently. It's basically, a 4-storey building , 20' wide, 65.5' long, 40' high and top off with Ardex roof. Walls wise, they are double layered red bricks with air gaps in between from the second floor up to keep the house temperature under control in normal weather conditions. For this, I will open 4" PVC ventilation holes with 4' apart on all external walls below beams to let the hot air out from the air gap with heat derived from the sun. And 4" PVC ventilations holes with 4' apart on all internal walls at 1' up from the floors to let cooler air flow into the air gap from the house within. On top of that, I will make 4" PVC ventilations hole through the double walls with 4' apart on all walls at half wall height to let the air flow naturally inside out and vice versa and if there is still not enough air circulation in the entire building, I will consider making ventilation holes through the floor slabs to let the hot air out from the lowest floor to the top most floor in a more natural way. The control room with sound systems would be 20'x7' on the ground floor leaving other areas for future expansion but I really wish to have a control room next to the birds' entry hole on the top most floor because up close, I will see continued increase in the population of birds diving for hole utterly unyielding in attitude at night fall. Not only a pleasure to watch, I will also go home with a sense of satisfaction by providing good sanctuary for this great species.
