The climate in a primary space within a building having a secondary space op en to and above the primary space is controlled by creating a primary microclimate within the primary space that is resistant to convection phenomena in the primary and secondary spaces. When the temperature in the secondary space is higher than the temperature in the primary space, air is drawn from the secondary space and discharged into the primary space at an initial air exchange rate which causes the temperature in the primary space to rise and the temperature in t he secondary space to fall. When the temperature in the primary space is greate r than or equal to the temperature in the secondary space, the air exchange ra te is set at a primary microclimate maintenance rate such that the temperature in the primary space remains equal to or greater than the temperature in the secondary space, thereby establishing the primary microclimate in the primary space.</ SDOAB>
