Microclimate cooling system for an indoor/outdoor stadium

A microclimate cooling system for an indoor/outdoor stadium comprising:

• 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, the microclimate cooling system operational in either the first position or the second position;
• a field surrounded by the stadium;
• a tiered seating approximately the length of the field positioned adjacent a first side of the field;
• a raised concrete barrier adjacent a second side of the field opposing the first side of the field;
• a first wall adjacent a third side of the field, the first wall perpendicular to the tiered seating extending between at least a portion of the tiered seating and the raised concrete barrier;
• a second wall adjacent a fourth side of the field, the second wall perpendicular to the tiered seating extending between at least a portion of the tiered seating and the raised concrete barrier;
• a plurality of air handling units, the plurality of air handling units supplying cooling air to the tiered seating;
• wherein the first wall and the second wall funnel the cooling air so that the cooling air flows from the tiered seating down to the field creating a cooled microclimate around the tiered seating and the field;
• and
• wherein a first air density in the an upper portion of the stadium volume, positioned above the microclimate, is greater than a second air density associated with the microclimate.

A microclimate cooling system for an indoor/outdoor stadium comprising:

• 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 natural grass pitch surrounded by the stadium, wherein the second position exposes the natural grass pitch natural ultra-violet light for photosynthesis;
• a tiered seating approximately the length of the natural grass pitch positioned adjacent a first side of the natural grass pitch, the tiered seating comprising:
• a plurality of seating tiers, each seating tier having a plurality of seats, the plurality of seats having a plurality of multi-dimensional perforations to facilitate air flow;
• a riser between each seating tier;
• a plurality of ventilation outlets formed within the riser to deliver a cooling air to the tiered seating;
• a diffuser positioned over each ventilation outlet, the diffuser having self-balancing back pressure;
• a raised concrete barrier adjacent a second side of the natural grass pitch opposing the first side of the natural grass pitch, the raised concrete barrier being part of an external façade;
• a first wall adjacent a third side of the natural grass pitch, the first wall perpendicular to the tiered seating extending between at least a portion of the tiered seating and the raised concrete barrier;
• a second wall adjacent a fourth side of the pitch, the second wall perpendicular to the tiered seating extending between at least a portion of the tiered seating and the raised concrete barrier;
• and
• a plurality of air handling units, the plurality of air handling units supplying cooling air to a cooling plenum positioned beneath the tiered seating, the cooling plenum fluidly connected to the plurality of ventilation outlets, wherein cooling air delivered from the cooling plenum to the plurality of ventilation outlets delivers a focused cooling air to the tiered seating that flows down to the natural grass pitch.
