Dispersion pattern of carbon dioxide from human sources - afactor to consider in demand controlled ventilation systems.

Carbon dioxide from (simulated) people distributes fairly evenly in a closed office room, but can show an irregular height distribution when the door to a connecting space is open. The distribution and room to room transfer of carbon dioxide is evaluated in a 4-room test building and is discussed in terms of its implication for C02-controlled ventilation.
