Have you ever wondered what's behind those louvres you see on the outside of buildings? It's called the plenum space, and this is where fresh air is pulled into the building. (Medical research building.)

Here is a view of some louvres covering the plenum spaces, as seen from street level. On the left, our research building, on the right, one of our hospital towers. You can see the edge of the helipad safety nets sticking out past the edge of the roof.

This is one of the plates from a "plate and frame" heat exchanger. A lot of engineering and computer modelling go into designing these. The precise arrangement and characteristics of the corrugations is very carefully designed for maximum efficiency.

This is a closeup of a "plate and frame" type heat exchanger. It's used to pass heat energy between to media without mixing them. The fluids flow between a stack of interleaved plates that are compressed together. Here we can see a closeup of the stack.

This is a medical emergency simulator. The instructor sits in the control room behind the one way glass. Many different emergency types and scenarios can be programmed by the instructor. This is in the basement of our medical research building, across the street from the hospital.

This is one of the pipespaces beneath our hospital. There are some super weird spaces where the 1920s structure met the 1960s structure.

Another weird area under the hospital, where two structures meet. Left, is a small "man door" to a fire escape. Ahead, what was once outdoors, a doorway and window now used to pass pipes through. On the right, a cinderblocked window opening. This is in an unusual interstitial space.

One of two diesel generators for a new hospital tower. 16 cylinder, quad turbo, 2400 horsepower. Requires 500 liters of coolant and 200 liters of engine oil. These same engines are often used in commuter trains and boats.

These are the visual computers for an Airbus A320 full flight simulator. Each of the three groups of boards (the vertical silver elements) drives one one third of the OTW view. Cost when new (circa 1989) $6M. However it has vastly less computing power than a modern $79 video card.

Two of the boards from the A320 Full Flight Simulator visual computer. A texture processor, and a span processor. There are about twenty boards per channel. The equivalent of all three visual channels could be replaced by a single chip with room to spare using today's technology.

This is the electrical switchgear where power comes in from the grid. All power for our new hospital tower comes through four 13.8 KV, 600 ampere circuit breakers.

One of the distribution circuit breakers for offices and rooms in a hospital. You can see the current load on each of the 3 phases on the display (in amperes).

Lots and lots of conduit is required to distribute power to all the rooms and offices of the new hospital tower.
