Well, as you see ... you see not so much about "Technical - Buliding - Equipment" (TBE) Exept the Pyramids of Giza (2620 BC) were already equipped with TBE. As there was ventilation, transportation routes, water collectors, lifts and so on. The Romans, as shown here, had have quite perfect TBE in this Roman Villa in Odenwald. They had ideas from spa to the heater. O.K. ... admitted ... HACON will be quite better :-)) in TBE working.
How smart we will go up to the issue of TBE, you will see here in a few days. So I have to take some interviews with our engineers and have to sort some pictures. See you later ...
Feel free to "click" here again, to see the maximum of TBE à la HACON.
