BLE modules for building applications

I am working in a project to create a mesh wireless sensor network(WSN). I am very interested in doing so using mesh BLE devices. However, this topic is completely new for me and I have faced some challenges to fully determine the performance of BLE in a similar application to mine. Thus, I would like to ask some technical questions hoping to get better understanding for my project.

1. The sensors will be operating inside buildings, very close to aluminium windows frames and other metals. Thus, I would like to know what Is an estimated range in meters of BLE modules inside building applications?
2. Following the previous questions, what would be the size of the antenna to reach that range and power consumption? Can it be a PCB antenna? What kind of support you can provide on this?
3. Is there any limitation related to the number of nodes I can implement in the mesh wireless sensor network? 
4. Finally, what is a good estimation of the Throughput of the BLE module for this kind of application?

PS: I do understand that giving exact numbers without knowing all details of the application is difficult but ballparks numbers based on your experience would be very insightful.

Thank you for your help, and looking forward to your answers.
