CBC Section 1206.3.2 requiros that court endosed on all four sides to ba provided with a horizontal air intake at the botlom of lho court or be adlacent to a yard or publlc way. To comply wlth the lntent of thls seclion, th6 opon-ended lirelighter tunnels will provide an avenua for natural ventilation from an ad,iacent court that is equivalent to the roquked opâ‚¬ning of 10 square feet connected directly to a street or yard. Tho courts ln the prolect buildings are much larger than the minimum dimensions required by Section 1206.3 (i.e. 9' x 16' minlmum dimensions for a S-story court). Courtyards 1 and 2 in Bullding B have approximate dimensions of 62' x 90' where Courtyard 3 has approximate dlmenslons of 48190'. These dimenslons provldo a court area that ls at lâ‚¬ast 30 limos largor than the minimum size court required by CBC Section 1206.3. The largâ‚¬r sizes of th6 courts within the prdect buildings do not havo the same characterisllcs of a smaller four-sided court that can act as a chlmnsy during summer wâ‚¬ather whon lhe bullding mass is heatod from the daytimo sun (referonced attached drawing sh6ot A2.2.1). Additionally, it ls not intended for the courls to functlon as an etlicient sourco of natural ventilation for tho spaces they front (i.e. dwelling unlts, lounges, otc) lh6refore the requirement for having the courts abut a yard or publlc way is less essential.
