This Partial Sections reveals the tiered affect of the green roof on the south side , the variable sun control devices which give occupants some control over their space and a modest amount of views.
The structural system is suggested here as a topped prestressed concrete plank system on steel beams and encased concrete column. Planks will be fabricated for the second and third floor off site while the structure of the first floor will be poured concrete using the gravel from the sloped north face as part of the on site batching for the concrete. steel cleats will be used to hold the planks to the beams during erection and before the topping is in place. Key ways will be poured in place once they have been set
Inverted steel trusses supported on the top cord will be used in the Educational area. This is done to provide an acoustical setting for events -perhaps musical and even outdoor music for special events at the location which will be used by others in the community. Like many buildings, this is a hybrid of different structural material.
The seismic control of this building is enhanced by the stepped back edifice which will be more stable in a seismic event.

Tom, you almost tricked me, the section looked quite good without zooming in. I have major concerns with your section. Please try to address them (see posting to details on my blog):
- Material, gravity: you throw many materials into the section; how do they transition from one to the next? How are they held up? Establish a load path from finish material to substructure I, substructure II to frame to foundation! Show your understanding of how it might be put together. How is the earth for the green roofs retained? Is there a parapet on your roof? The trespa panels will not sit directly on stud frame. Show sheathing, air barrier, et cetera. There is (hopefully) a top edge to the trespa panels (roof and third floor), how is the planter on the third floor finished on the inside?
- Energy: Insulation layers need to be continuous from roof to wall to ground. Windows will interrupt the layer, ideally the insulation hits the window at the glass line to avoid as many cold bridges as possible. It is unwise to have a concrete slab continuous from the inside to the outside. Provide a break in the slab, add a drop in the slab for waterproofing.
- Water: I need to see a continuous waterproofing membrane somewhere: roof, parapet, none in soffit, wall, flashing idea at window head, flashing into membrane at sill, trough between window and planter, planter, et cetera.
Not in my list, but equally important:
Inventions/uncommon systems: show to the laymen how does it work: adjustable louvers (show real sun ray cut-off lines, it might help you determine your geometry better), chilled beam (you are showing the equivalent of a radiator baseboard – very different from the diagram in your webpage), planter (plant material, how much soil, drainage, irrigation), et cetera
Your description needs to be followed up with drawings.
