       9 . The system of  claim 6  wherein the bottom wall of the plenum is at least substantially square shaped. 
   
   
       10 . The system of  claim 6  wherein:
 the bottom wall includes four corner areas; and   at least a portion of at least some of the plurality of outlet apertures are in each of the four corner areas.   
   
   
       11 . The system of  claim 1  wherein the air mixing chamber comprises a mixing chamber outer wall extending from the bottom wall at least substantially around the angular direction and defining a radially outwards side of the air mixing chamber. 
   
   
       12 . The system of  claim 11  wherein the mixing chamber outer wall is at least substantially quadrangular in shape. 
   
   
       13 . The system of  claim 12  wherein the mixing chamber outer wall is at least substantially square in shape. 
   
   
       14 . The system of  claim 11  further comprising a grille member extending from the mixing chamber outer wall in the radial inwards direction with the grille member comprising:
 at least one louver located underneath the air mixing chamber; and   a central aperture located around the central axis.   
   
   
       15 . The system of  claim 14  wherein the grille member further comprises an upstanding wall located to be spaced radially inwards of the mixing chamber outer wall and extending toward the bottom wall, with the upstanding wall extending at least substantially around the angular direction. 
   
   
       16 . A ventilation system comprising:
 a plenum assembly comprising:
 an inlet aperture sized, shaped and located to receive primary air from a primary air source, 
 a plurality of walls defining a unitary interior volume of the plenum, the plurality of walls comprising a bottom wall defining a central axis of the ventilation system, and angular and radial directions with respect to the central axis, and 
 a plurality of outlet apertures defined in bottom wall; and 
   a heating/cooling unit located under the bottom wall and radially inwards of the plurality of outlet apertures, the heating/cooling unit extending at least substantially around the angular direction.   
   
   
       17 . The system of  claim 16  wherein the heating cooling unit comprises a matrix of fluid pipes. 
   
   
       18 . The system of  claim 16  wherein the heating/cooling unit has an outer footprint shaped at least substantially as a quadrangle. 
   
   
       19 . The system of  claim 16  further comprising an outer wall extending from the bottom wall in a direction away from the plenum assembly, with the outer wall extending at least substantially around the angular direction and being spaced apart radially outwards from the heating/cooling unit.
