Abstract: A passive indoor/outdoor stadium structure configured to reduce energy demands from the stadium structure includes a moveable roofing system and a micro-climate cooling system. The moveable roofing system covers an interior space of the stadium and has an open position and a closed position. The roofing system includes a fixed half-dome roof and a revolving half dome roof retractable beneath the fixed half dome roof, both the fixed half dome roof and the revolving half dome roof having an outer half dome clad with a plurality of solar hoods positioned in an overlapping arrangement. The micro-climate cooling system for cooling the indoor/outdoor stadium includes a full circulation mode for cooling a stadium volume when the roofing system is in the closed position, and a micro-climate mode for cooling a portion of the stadium volume when the roofing system is in the open position.

Abstract: A microclimate cooling system for an indoor/outdoor stadium includes a partially rotatable roof, the rotatable roof having a first position environmentally sealing an interior of the stadium. and a second position exposing a portion of the interior to the atmosphere, a field surrounded by the stadium, and a tiered seating positioned adjacent a first side of the field. The system further includes a raised concrete barrier adjacent a second side of the pitch opposing the first side of the field, a first wall adjacent a third side of the field, and a second wall adjacent a fourth side of the field, the first and second walls perpendicular to the tiered seating extending between at least a portion of the tiered seating and the raised concrete barrier. The system further includes a plurality of air handling units for supplying cooling air to the tiered seating.

Abstract: A moveable roofing system for covering an interior space includes a fixed half-dome roof fixed to and supported by a first support structure, a rotatable half-dome roof rotatable about and supported by a second support structure, the second support structure being concentric to the first support structure, and, wherein the rotatable half-dome roof is configured to rotate about the second support structure.

Abstract: A revolving canopy roof for a stadium includes a fixed half dome and revolving half dome. The fixed half dome has an outer layer clad with a plurality of shading tents, the plurality of shading tents comprising a plurality of triangular shading panels, an inner layer clad with a plurality of triangular ethylene tetraflouroethylene panels, and a plurality of bracing elements connecting the outer layer to the inner layer. The revolving half dome includes an outer layer clad with a plurality of shading tents, the plurality of shading tents comprising a plurality of triangular shading panels, an inner layer clad with a plurality of triangular ethylene tetraflouroethylene panels, and a plurality of bracing elements connecting the outer layer to the inner layer.
