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.
Designing a comfortable inside climate for office buildings to operate within comfort limits (PMV+/-0.5) requires a flexible operating strategy. Two systems a VAV and a VHV are identified and compared to each other. Dynamic simulation techniques are used to obtain an optimal design, based upon comfort conditions not temperatures. The control strategies are optimised to minimize energy consumption while controlling the HVAC system to remain within comfort limits in the occupied zone.
