Changing With The Seasons

The diagram of the structure symbolizes a roof that would be allowed to move with the seasons. In summer, the roof would be in its “down” position, which would allow the roof to be at a lower angle to more directly capture solar energy as the sun is more directly over head in the summer (~67º to the horizon). This would allow the roof to also provide overhangs to the building to provide shade to the windows to block excessive heating from the sun. In winter, the roof would be in its “up” position, which would allow the roof to again more directly capture solar energy as the sun is closer to the horizon in winter (~20º). The steep slope of the roof would additionally allow for a reduction in snow load from 21psf on a roof slope of <30º, to as little as 12.6psf with a roof slope of 45º, which would require less materials to construct.

The connection diagram symbolizes what I believe a reasonable connection would look like. Of course this is not the only solution, but what is shown is a pin or gear in the truss/rafter system that is moveable. To move this pin, two Organic Farm employees (one on each half of the building) would turn a crank that would spin sets of gears that would move the mobile pin up or down the truss/rafter system. The pin at the top could be the final gear in the gear system.
