Building service sketches

Below are some sketches that try to illustrate my intended building services.. I think that the heating and daylighting are pretty self explanatory... The natural ventilation piece is a little more complicated though... I have a concept sketch for that below...

My thought is that I can bring natural ventilation in between where my container modules meet.. Perhaps some type of an adjustable louver can serve to allow ventilation in when desired and keep it out the rest of the time... My thought is that air can come in under the container and be forced to the back of the core building with the use of some type of baffle located within the ceiling plenum space... it can then work its way over the baffle and into the chimney stack to make it out thru the roof..... I think this could make for some great passive cooling of each of the floor slabs and container floors..
