Asymmetrical building surface baffles and building surface system

A building surface system comprising:

• a first support structure;
• a second support structure;
• and
• a plurality of baffles extending from the first support structure to the second support structure, wherein each baffle comprises:
• an elongate body extending along an axis from a first end to a second end, the elongate body having a depth including a narrow portion that extends away from the axis along a first direction and a wide portion, the wide portion including first and second projections that extend laterally outward from the first direction;
• a first aperture extending into the first end of the elongate body along the axis;
• and
• a second aperture extending into the second end of the elongate body along the axis,
• wherein each baffle is supported at the first end by a respective first pin segment that is inserted into the first aperture and is supported at the second end by respective second pin segment that is inserted into the second aperture.
