Another important factor is determining how to funnel the cool air to the base of the chimney so the suction effect can be achieved and ventilation can occur. Typically, one of two different methods is utilized for this process.

The first option uses windows on the lowest level of the building to capture cooler air and funnel it through the dwelling to the base of the chimney. This set-up requires no underground work and is best for structures that are maybe limited on ground area around the structure. The second method utilizes a pipe buried underground; the air in the pipe cools underground and is eventually drawn through the building to the chimney’s base where, through suction, the air passes into the solar chimney where it is heated and released.

Solar Innovations, Inc. can offer solar chimneys with operable or fixed vent options for the function. Both fixed and operable vents have a place in solar chimney applications, but if you’re not sure what is best for you, consult your Solar Innovations, Inc. sales representative.
