Rendered images of aggregated panels with tiles in different configurations, with a diagrammatic analysis of sun shading and ventilation effectiveness.

These are additional variation types, with the last being the most effective.

After receiving the material, we discovered that the bimetal is actually pre-curled, therefore starting curled when cold and flattening as it is heated, as shown in different lengths.

More studies of sun permeation at different times of the year, angles of panels, and direction of flaps.

Panel Testing

2011-05-27T08:02:00.000-07:00

SOLAR STUDIES

These are studies done on a portion of the panel simplifying the affect on the panels during different times of the day. Then I analyzed the efficiency of 3 different panelization patterns.

PANELS
These are panels I made of cardboard paper. The top right image is an extra wide panel (only half done due to assembling problems) with a guess as to how it might curl in the heat. I'm guessing because the horizontal dimension is so thin, that it will curl as shown.

PANEL VARIATIONS
5 different types of panels and how they would react in a heated situation or a half heated situation.

SHADOW STUDIES
Shadows at 3 different times of the day for 9 panel variations.

Jig mock up

2011-05-23T21:41:00.000-07:00

wood frame, with 1/2 in threaded rod, adjustable to min of 14" x 14" and max of 42 " x 42". max height of 26 " . Final Jig will need to be slightly larger to accommodated offset for clamps. cost for wood and hardware and clamps is roughly 110$. moves pretty smoothly and tightens well.

catia model places panel at "flat"as possible and returns 4 plan dimensions and 4 heights to set jig. Maybe Yukee could help automate this. We would also do this in grasshopper is we end up using rhino.

basic 90 d clamp, I ordered 4 of these, and singles of a couple of other options should be here by end of the week.
