were accurately controlled bydistributing the conditioned air evenly. ... AIR DISTRIBUTIOIV This was because the primary mixing of incom-ing air with existing room air took place withinthese diffusers, and because all air turbulence waslimited to their vicinity high above occupancyareas. With these diffusers discharging the air in adownward, low-velocity pattern, obstacles such ascolumns, machines and furniture did not deflectthe air-flow. Therefore, dead air pockets—whetherunder-cooled or over-cooled—were eliminated. The over-all result was even, draftless air-dis-tribution that caused both temperature and humid-ity to be closely equalized throughout the room. This scientific air-diffusion makes it possible todistribute air throughout a large or small room—aswell as a convention auditorium—at low velocity,even when unusually high velocities are employedin the air-ducts. For example, in a building of theInternational Business Machines Corporation, 400,- (Continued on Page 35)

Air is distributed uniformly and without drafts over tiie vast floor areaof this loft of the Vega Aircraft plant, at Burbank, California. By scientificair-diffusion, Anemostats (on the under-side of the trusses) insure equal-ization of both temperature and humidity.

This isnt a new idea at all, for the Greeks andSyrians had them, while the Romans went in forelaborate roof gardens. They had literally roofforests with plants in boxes, pots and lead urns,while the floor was often of mosaic that supportedin some instances pergolas of stone over whichgrape vines grew. Even today the roof garden isnot only for the city, for suburbans may have them,too. In fact there is an advantage in the sioburbandistrict as it is not likely to suffer so much wind,for often in the city sharper wind with bellowseffec
